case A) The equation of the diagonal AC is [tex]x+y=0[/tex]

case B) The equation of the diagonal BD is [tex]x-y=0[/tex]

Step-by-step explanation:

Part 1)

step 1

Find the midpoint

The formula to calculate the midpoint between two points is equal to

[tex]M=(\frac{x1+x2}{2},\frac{y1+y2}{2})[/tex]

substitute the values

[tex]M=(\frac{2-6}{2},\frac{-3+5}{2})[/tex]

[tex]M=(-2,1)[/tex]

step 2

The equation of the line into point slope form is equal to

[tex]y-1=\frac{9}{7}(x+2)\\ \\y=\frac{9}{7}x+\frac{18}{7}+1\\ \\y=\frac{9}{7}x+\frac{25}{7}[/tex]

step 3

Convert to standard form

Remember that the equation of the line into standard form is equal to

[tex]Ax+By=C[/tex]

where

A is a positive integer, and B, and C are integers

[tex]y=\frac{9}{7}x+\frac{25}{7}[/tex]

Multiply by 7 both sides

[tex]7y=9x+25[/tex]

[tex]9x-7y=-25[/tex]

Part 2)

step 1

Find the midpoint

The formula to calculate the midpoint between two points is equal to

[tex]M=(\frac{x1+x2}{2},\frac{y1+y2}{2})[/tex]

substitute the values

[tex]M=(\frac{1+5}{2},\frac{0-2}{2})[/tex]

[tex]M=(3,-1)[/tex]

step 2

Find the slope

The slope between two points is equal to

[tex]m=\frac{-2-0}{5-1}=-\frac{1}{2}[/tex]

step 3

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

Find the slope of the line perpendicular to the segment joining the given points

[tex]m1=-\frac{1}{2}[/tex]

[tex]m1*m2=-1[/tex]

therefore

[tex]m2=2[/tex]

step 4

The equation of the line into point slope form is equal to

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=2[/tex] and point [tex](1,0)[/tex]

[tex]y-0=2(x-1)\\ \\y=2x-2[/tex]

step 5

Convert to standard form

Remember that the equation of the line into standard form is equal to

[tex]Ax+By=C[/tex]

where

A is a positive integer, and B, and C are integers

[tex]y=2x-2[/tex]

The slope between two points is equal to

[tex]m=\frac{2.5-3}{2+2}=-\frac{1}{8}[/tex]

step 4

The equation of the line into point slope form is equal to

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=-\frac{1}{8}[/tex] and point [tex](-2,3)[/tex]

[tex]y-3=-\frac{1}{8}(x+2)\\ \\y=-\frac{1}{8}x-\frac{1}{4}+3\\ \\y=-\frac{1}{8}x+\frac{11}{4}[/tex]

step 5

Convert to standard form

Remember that the equation of the line into standard form is equal to

[tex]Ax+By=C[/tex]

where

A is a positive integer, and B, and C are integers

[tex]y=-\frac{1}{8}x+\frac{11}{4}[/tex]

Multiply by 8 both sides

[tex]8y=-x+22[/tex]

[tex]x+8y=22[/tex]  

Part 4)

In this problem the hypotenuse is AC (plot the figure)

step 1

Find the slope AC

The slope between two points is equal to

[tex]m=\frac{4-5}{3+5}=-\frac{1}{8}[/tex]

step 3

Convert to standard form

Remember that the equation of the line into standard form is equal to

[tex]Ax+By=C[/tex]

where

A is a positive integer, and B, and C are integers

[tex]y=\frac{3}{4}x+\frac{6}{4}-2[/tex]

[tex]y=\frac{3}{4}x-\frac{2}{4}[/tex]

step 3

Convert to standard form

Remember that the equation of the line into standard form is equal to

The function f(x) = ?x2 + 16x ? 60 models the daily profit, in dollars, a shop makes for selling candles, where x is the number of candles sold, and f(x) is the amount of profit. Part A: Determine the vertex. What does this calculation mean in the context of the problem? (5 points) Part B: Determine the x-intercepts. What do these values mean in the context of the problem?

Answers

Answer:

Step-by-step explanation:

A

The vertex form: f(x) = a(x-h)^2 + k

f(x) = x^2 + 16x + 60 = (x^2 + 16x) + 60

We want to get a perfect square in the brackets, so we solve for our b^2 coefficient.

b^2 = (16/2)^2 = 64

f(x) = (x^2 + 16x + 64 - 64) + 60. Note we subtracted 60 right away to end up with an equivalent expression and not some other function.

f(x) = (x+8)^2 - 4, as you can see it matches the general vertex form.

The vertex form shows when the profit is minimal. The point (h, k) or f(h).

B. The x-intercepts or when the function is equal to 0, or the profit is 0 in the context of the problem.

f(x) = x^2 + 16x + 60 set = 0

x^2 + 16x + 60 = 0

[tex]x_{12} = \frac{-16 \pm \sqrt{256 - 4(1)(60)}}{2} = \frac{-16 \pm \sqrt{16}}{2} = \frac{-16 \pm 4}{2} = -8 \pm 2[/tex]

Answer:

the vertex is either the maximum or minimum value

since the leading coefinet is negative (the number in front of the x² term), the parabola opens down and is a maximum

so

A.

a hack version is to use the -b/(2a) form

if  you have f(x)=ax²+bx+c, then the x value of the vertex is -b/(2a)

so

given

f(x)=-1x²+16x-60

the x value of the vertex is -16/(2*-1)=-16/-2=8

the y value is f(8)=-1(8)²+16(8)-60=

-1(64)+128-60=

4

the vertex is (8,4)

so you selll 8 candels to make the max profit which is $4

B.

x intercepts are where the line crosses the x axis or where f(x)=0

solve

0=-x²+16x-60

0=-1(x²-16x+60)

factor

what 2 numbers multiply to get 60 and add to get -16

-6 and -10

0=-1(x-6)(x-10)

set each factor to 0

0=x-6

x=6

0=x-10

10=x

x intercepts are at x=6 and 10

that is where you make 0 profit

The school production of​ 'Our Town' was a big success. For opening​ night, 503 tickets were sold. Students paid ​$4.00 ​each, while​ non-students paid ​$6.00 each. If a total of $ 2296.00 was​ collected, how many students and how many​ non-students attended?
The number of students was
nothing. ​(Simplify your​ answer.)
The number of​ non-students was
nothing. ​(Simplify your​ answer.)

Answers

4x➕6(503-x)=2296

Distribute the 6 into the parentheses

Let x represent the students

503-x will represent the non-students

4x➕3018➖6x=2296

Then combine like terms

-2x➕3018=2296

Now since you move your constant your sign has to change as well,

-2x=2296➖3018

Then subtract

-2x=-722

Then divide both sides by -2

You are left with x=361

This represents the students

503➖361= 142 which equal the non-students

Therefore your answer is:

361=students

142=non-students

Hope this helps! :3

Answer:

Apply the distributive property

1/4(16a+8b+c)

Answers

Answer:

4a + 2b + 1/4 c.

Step-by-step explanation:

1/4(16a+8b+c)

= 1/4 * 16a + 1/4 * 8b + 1/4 * c

= 4a + 2b + 1/4 c.

Final answer:

To apply the distributive property to the expression 1/4(16a+8b+c), we distribute the 1/4 to each term inside the parentheses and simplify the expression.

Explanation:

To apply the distributive property to the expression 1/4(16a+8b+c), we distribute the 1/4 to each term inside the parentheses. This means multiplying 1/4 by 16a, 1/4 by 8b, and 1/4 by c. The distributive property states that a (b + c) = ab + ac. So, the expression becomes:

1/4(16a) + 1/4(8b) + 1/4(c)

Since 1/4 times any number equals the number divided by 4, we can simplify further:

(16a/4) + (8b/4) + (c/4)

Which simplifies to:

4a + 2b + c/4

Answers

A function assigns the values. The temperature that will model most accurately predict the time spent cooling will be 300.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

For the given function [tex]f(t)=349.2 (0.98)^t[/tex], the value of t which will lie within the given function range will be the value function that will model most accurately predict the time spent on cooling. Therefore, let's substitute the values and check,

A.) t = 0

[tex]f(t)=349.2 (0.98)^t\\\\0=349.2 (0.98)^t[/tex]

As the value of t will lie at infinite, therefore, this will not give an accurate prediction of the model.

B.) f(t) = 100

When the value of the function will be 100 then the value of t will be 61.6, therefore, this can not be the most accurate prediction.

C.) f(t) =300

When the value of the function will be 300 then the value of t will be 7.5, therefore, this is the most accurate prediction.

D) f(t) = 400

When the value of the function will be 400 then the value of t will be -6.724, therefore, this can not be the most accurate prediction.

Thus, the temperature that will model most accurately predict the time spent cooling will be 300.

Given triangle QRS is congruent to triangle TUV, QS = 3v + 2 and TV = 7v - 6, find the length of QS and TV.

Answers

Answer:

The length of QS and TV is 8 units

Step-by-step explanation:

we know that

If triangle QRS is congruent with triangle TUV

then

QS=TV

QR=TU

RS=UV

In this problem

we have

QS=3v+2

TV=7v-6

so

QS=TV

3v+2=7v-6

Solve for v

7v-3v=2+6

4v=8

v=2

Find the length of QS

substitute the value of v

QS=3(2)+2=8 units

so

TS=8 units

Final answer:

Triangle QRS is congruent to triangle TUV, so side QS is equal to side TV. By setting the expressions for QS and TV equal and solving for 'v', we find that both lengths are 8 units.

Explanation:

To solve the problem of finding the length of QS and TV given that triangle QRS is congruent to triangle TUV, and being given the expressions QS = 3v + 2 and TV = 7v - 6, we must recognize that congruent triangles have corresponding sides of equal length. Thus, we can set the expressions for QS and TV equal to each other:

3v + 2 = 7v - 6

We then solve for 'v' by subtracting 3v from both sides:

2 = 4v - 6

Next, we add 6 to both sides:

8 = 4v

Divide both sides by 4 to find 'v':

v = 2

Now that we have the value of 'v', we can substitute it back into the expressions for QS and TV to find their lengths:

QS = 3(2) + 2 = 8

TV = 7(2) - 6 = 8

Therefore, the length of QS and TV is 8 units each.

3) y = cos (3x - π/3)

Looking at the graphs, we can see that the identical ones

are equations one and three

Correct option:

c. 1 and 3

Answer:

The correct option is:

             option: c     c.   1 and 3

Step-by-step explanation:

The first trignometric function is given by:

     [tex]y=\sin (3x+\dfrac{\pi}{6})[/tex]

and also we know that:

[tex]\sin \theta=\cos(\dfrac{\pi}{2}-\theta)[/tex]

This means that:

[tex]\sin (3x+\dfrac{\pi}{6})=\cos (\dfrac{\pi}{2}-(3x+\dfrac{\pi}{6})\\\\\\\sin (3x+\dfrac{\pi}{6})=\cos (\dfrac{\pi}{2}-3x-\dfrac{\pi}{6})\\\\\\\sin (3x+\dfrac{\pi}{6})=\cos (\dfrac{\pi}{2}-\dfrac{\pi}{6}-3x)\\\\\\\sin (3x+\dfrac{\pi}{6})=\cos (\dfrac{2\pi}{6}-3x)\\\\\\\sin (3x+\dfrac{\pi}{6})=\cos (\dfrac{\pi}{3}-3x)\\\\\\\sin (3x+\dfrac{\pi}{6})=cos (-(3x-\dfrac{\pi}{3}))[/tex]

As we know that:

[tex]\cos (-\theta)=cos(\theta)[/tex]

Hence, we have:

[tex]\sin (3x+\dfrac{\pi}{6})=\cos (3x-\dfrac{\pi}{3})[/tex]

Also,  by the graph we may see that the graph of 1 and 2 function do not match.

Hence, they are not equivalent.

Answers

Answer:

The x intercepts are x=-4 and x=2

axis of symmetry x=-1

vertex (-1,-9)

D: {x: all real numbers}

R: {y: y≥ -9}

Step-by-step explanation:

f(x) = x^2+2x-8

y= x^2+2x-8

Factor the equation

What 2 numbers multiply to -8 and add to 2

4*-2 = -8

4+-2 =2

y = (x+4) (x-2)

The x intercepts are found when we set y =0

0=  (x+4) (x-2)

Using the zero product property

x+4=0   x-2 =0

x=-4 and x=2

The x intercepts are x=-4 and x=2

The axis of symmetry is halfway between the x intercepts.  It is symmetric must be in the middle of the x intercepts

1/2 (-4+2) = 1/2(-2) = -1

The axis of symmetry is at x=-1

To find the vertex, it is along the axis of symmetry.  Substitute x=-1 into the equation

y = (x+4) (x-2)

y = (-1+4) (-1-2)

  =3*-3

  =-9

The vertex is (-1,-9)

The domain is the values that x can take

x can be any number

D: {x: all real numbers}

The range is the values that y can take

since the parabola opens upward, the vertex is the minimum,Y must be greater than or equal to -9

R: {y: y≥ -9}

In a particular game, a spinner with four equally-sized sectors labeled 1, 4, 6, and 8 is spun twice. One turn is considered 2 spins of the spinner.

If the sum of the spins is even, you move forward 6 spaces. Otherwise, you move back 2 spaces.

What is the mathematical expectation for the number of spaces moved in one turn?



A. 3 spaces forward
B. 3 spaces backward
C. 1 space backward
D. 1 space forward

Answers

Answer:

The mathematical expectation for the number of spaces moved in one turn is:

           A.    3 spaces forward.

Step-by-step explanation:

Th result or the sample space on spinning a spinner twice is:

           (1,1)    (1,4)    (1,6)    (1,8)

           (4,1)   (4,4)    (4,6)  (4,8)

           (6,1)   (6,4)    (6,6)  (6,8)

           (8,1)   (8,4)    (8,6)   (8,8)

Total number of outcomes= 16

The number of outcomes whose sum is even= 10

( Since the outcomes are: {(1,1) , (4,4) , (4,6) , (4,8) , (6,4) , (6,6) , (6,8) , (8,4) , (8,6) , (8,8)}  )

The number of outcomes whose sum is odd= 6

( Since, the outcomes are: { (1,4) , (1,6) , (1,8) , (4,1) , (6,1) , (8,1) }

Probability(sum even)=10/16

Probability(sum odd)=6/16

Hence, the expectation is:

 [tex]E(X)=\dfrac{10}{16}\times (+6)+\dfrac{6}{16}\times (-2)\\\\\\E(X)=\dfrac{60-12}{16}\\\\\\E(X)=\dfrac{48}{16}\\\\\\E(X)=+3[/tex]

                 Hence, the answer is:

              A.  3 spaces forward.

What is the sum of the first 703 terms of the sequence -5, -1, 3, 7, ...?

Answers

Answer:

983497

step-by-step explanation:

The sum formula of arithmetic sequence is given by:

[tex]S_n = \frac{n}{2}(2a_1 +(n - 1)d[/tex]

a_1 is the first term, n is the nth term and d is the common difference

From the given information

[tex]d = - 1 -( - 5) = - 1 + 5 = 4[/tex]

[tex]a_1 = - 5 \: and \: n = 703[/tex]

By substitution we obtain:

[tex]S_{703}= \frac{703}{2}(2( - 5) +(703- 1)4)[/tex]

[tex]S_{703}= \frac{703}{2}( - 10 + 2808)[/tex]

[tex]S_{703}= \frac{703}{2}(2798)[/tex]

[tex]S_{703}=98397[/tex]

Answer:

S = 983,497

Step-by-step explanation:

We are given the following sequence and we are to find the sum of the first 703 terms of this sequence:

[tex]-5, -1, 3, 7, ...[/tex]

Finding the common difference [tex]d[/tex] = [tex]-1-(-5)[/tex] = [tex]4[/tex]

[tex]a_1=-5[/tex]

[tex]a_n=?[/tex]

[tex]a_n=a_1+(n-1)d[/tex]

[tex] a_n = - 5 + ( 7 0 3 - 1 ) 4 [/tex]

[tex] a _ n = 2803 [/tex]

Finding the sum using the formula [tex]S_n = \frac{n}{2}(a_1+a_n)[/tex].

[tex]S_n = \frac{703}{2}(-5+2803)[/tex]

S = 983,497

Find the difference between the medians of Set A and Set B as a multiple of the interquartile range of Set A. A) 1 2 B) 3 4 C) 1 1 2 D) 2

Answers

Answer:

B) 3/4

Step-by-step explanation:

3 /4

Set A interquartile range = 4

Difference between medians is 3.

Therefore,  3 /4

The difference between the median of set A and set B as a multiple of interquartile range of set A is 3/4.

Set A interquartile range is 4

Difference between their medians is 3

What is interquartile range?

The interquartile range is a measure of the “middle fifty” in a data set in which a range is a measure of the beginning and end are in a set, an interquartile range is a measure of the bulk of the values lie.

Difference between the median = Median / Interquartile range of A

                                                       = 3/4

Thus, the difference between the median set A and set B as multiple of interquartile range is 3/4.

B. This graph is a function whose range is the set {3}
C. The equation fo this line is x=3.
D. This graph is a function whose domain is the set {3}
E. This graph is a function because the value of x is the same for every value of y.

Answers

Answer:

Option A

Option C

Step-by-step explanation:

A relationship is defined as a function if and only if each element of the "domain" set is assigned only one element of the "range" set. That is, there is only one output value y assigned to each input value x.

The relation x = 3 is not a function because there are infinite output values y, assigned to the same input element x.

(3, 2), (3, 5) (3, 9) (3,10000)

Then the option A is true

Option C is also true, the equation of the line shown is

[tex]x = 3[/tex]

The rest of the options are false because x = 3 is not a function

Graph a system of equations to solve log (−5.6x + 1.3) = −1 − x. Round to the nearest tenth. From the least to the greatest, the solutions are: x ≈ and x ≈ .

Answers

Answer:

See the graph attachedx₁ ≈ - 2.1x₂ ≈ 0.2

Explanation:

To solve log (−5.6x + 1.3) = −1 − x graphycally, you must graph this system of equations on the same coordinate plane:

Equation 1: y = log (5.6x + 1.3)Equatin2:    y = - 1 - x

1) To graph the equation 1 you can use these features of logarithmfunctions:

Domain: positive values ⇒ -5.6x + 1.3 > 0 ⇒ x < 13/56 (≈ 0.23)

Range: all real numbers (- ∞ , ∞)

x-intercept:

        log ( -5.6x + 1.3) = 0 ⇒ -5.6x + 1.3 = 1 ⇒x = 0.3/5.6 ≈ 0.054

y-intercept:

       x = 0 ⇒ log (0 + 1.3) = log (1.3) ≈ 0.11

Pick some other values and build a table:

        x            log (-5.6x + 1.3)

        -1           0.8

        -2           1.1

        -3           1.3

You can see such graph on the picture attached: it is the red curve.

2) Graphing the equation 2 is easier because it is a line: y = - 1 - x

slope, m = - 1 (the coeficient of x)y - intercept, b = - 1 (the constant term)x - intercept: y = 0 = - 1 - x ⇒ x = - 1The graph is the blue line on the picture.

3) The solution or solutions of the equations are the intersection points of the two graphs. So, now the graph method just requires that you read the x coordinates of the intersection points. From the least to the greatest, rounded to the nearest tenth, they are:

Answers

Answer:

Sanjay watched television last weekend for 180 minutes.

Step-by-step explanation:

Sanjay watched 3 television shows and one movie on television last week.

Time duration of 1 television shows = 30 mins

Time duration of 3 television shows = 3* 30 = 90 mins

Time duration of movie = 90 mins

Total number of minutes Sanjay watched television last weekend = Time duration of 3 television shows + Time duration of movie

= 90 + 90

= 180 min

So, Sanjay watched television last weekend for 180 minutes.

PLEASE HELP ASAP! WILL GIVE BRAINLIEST! Thank you!
Given: mKP=2mIP, mIVK=120°
Find: m∠KJL

Answers

That is 99 degrees if you have the triangle facing the other way

the measure of angle KJL is [tex]\( 40^\circ \)[/tex].

Given information

[tex]\( m(KP) = 2 \cdot m(IP) \)\\\( m(IVK) = 120^\circ \)[/tex]

Using the fact that the sum of angles in a circle is [tex]\( 360^\circ \)[/tex], we have:

[tex]\[ m(KP) + m(IP) + m(IVK) = 360^\circ \][/tex]

Substituting the given values:

[tex]\[ 2 \cdot m(IP) + m(IP) + 120^\circ = 360^\circ \][/tex]

Solving for [tex]\( m(IP) \)[/tex]:

[tex]\[ 3 \cdot m(IP) = 360^\circ - 120^\circ \]\[ 3 \cdot m(IP) = 240^\circ \]\[ m(IP) = \frac{240^\circ}{3} \]\[ m(IP) = 80^\circ \][/tex]

Finding [tex]\( m(KP) \)[/tex]:

[tex]\[ m(KP) = 2 \cdot m(IP) = 2 \cdot 80^\circ = 160^\circ \][/tex]

Using the angle formed by a tangent and a secant theorem, we can find [tex]\( m(\angle KJL) \)[/tex]:

[tex]\[ m(\angle KJL) = \frac{1}{2} (m(KP) - m(IP)) \][/tex]

Substituting the known values:

[tex]\[ m(\angle KJL) = \frac{1}{2} (160^\circ - 80^\circ) \]\[ m(\angle KJL) = \frac{1}{2} (80^\circ) \]\[ m(\angle KJL) = 40^\circ \][/tex]

Therefore, the measure of angle KJL is [tex]\( 40^\circ \)[/tex].

The complete question is:

given:  [tex]\( m(KP) = 2 \cdot m(IP) \)\\[/tex] and [tex]\( m(IVK) = 120^\circ \)[/tex]

find: m∠KJL.
