If the measure of a central angle is 124°, then what is the measure of the arc it creates? 248° 62° 31° 124°


PLEASE HELP!!!!!!!!!!!

Answer: C

Step-by-step explanation:

1 + 2sin(x+pi)

1 is adding to the y, so it is a vertical shift of 1 unit,

2 is a stretch because it is multiplying to the sin,

and pi is adding to the x, so it is a phase shift.

D

(-71+1) + 0 = (-71+1)

This is because the whole equation involves addition thus it is an example of associative property of addition

Answer:

(-71 + 1) + 0 = (-71 +1)

Step-by-step explanation:

Given 3 numbers: a,b,c

Associative property of addition: (a + b) + c = a + (b + c)

On this case: a= -71

b = 1

c = 0

(a + b) + c = (-71 + 1) + 0 = -70 + 0 = -70

(-71 + (1 + 0)) = (-71 + 1) = -70

Both the sums are equal to -70 and hence the associative property of addition for the three numbers a= -71, b = 1, c= 0 holds.

All the other options in the question contain a reference to variable i and does not have the same three values a,b,c on both sides of the equality. So they do not represent the associative property.

Answer:

g^5h^2

Step-by-step explanation:

12g^5h^4, g^5h^2

This is one way of doing it. Break down every number and every variable into a product of the simplest factors. Then see how many of each factor appear in both monomials.

12g^5h^4 = 2 * 2 * 3 * g * g * g * g * g * h * h * h * h

g^5h^2 = g * g * g * g * g * h * h

So far you see every single prime factor of each monomial.

Now I will mark the ones that are present in both. Those are the common factors.

12g^5h^4 = 2 * 2 * 3 * g * g * g * g * g * h * h * h * h

g^5h^2 = g * g * g * g * g * h * h

The greatest common factor is the product of all the factors that appear in both monomials.

GCF = g * g * g * g * g * h * h = g^5h^2

Answer:

1) the factored form is  y= ( x-5 ) ( x+4 )

2) the vertex is (4.5, -0.25)

3) the y intercept is when x equals 0 so it is at (0,20)

4) it opens upward and the vertex is (4.5, -0.25) the x intercepts are (4,0) and (5,0) and the y intercept is  (0,20)

5)

a. it dips  between 4 seconds and 5 seconds so the x intercepts are (4,0) and (5,0)

b. it is taken at the vertex aka the lowest point so the height is -0.25

Answer:

Part 1:

[tex]y= (x-4)(x-5)[/tex]

Part 2:

[tex](\frac{9}{2}, - \frac{1}{4})[/tex]

Part 3:

[tex]Y=20[/tex]

Part 5:

The height:

[tex]-\frac{1}{4}[/tex]

The time:

[tex]\frac{9}{2}[/tex]s

Step-by-step explanation:

[tex]y = x^{2}  -9x+20[/tex] Is a quadratic equation.

Part 1:

We use [tex]x = \frac {-b \pm \sqrt {b^2 - 4ac}}{2a}[/tex] to factor quadratic equations

[tex]y = x^{2}  -9x+20[/tex]

a=1 b=-9 c=20

[tex]x = \frac {-(-9) \pm \sqrt {(-9)^2 - 4(1)(20)}}{2(1)}[/tex]

[tex]x = \frac {9 \pm \sqrt {81 -80}}{2}[/tex]

[tex]x = \frac {9 \pm {1}}{2}[/tex]

we solve both possibilities

[tex]x = \frac {9 + {1}}{2}=5[/tex]

[tex]x = 5[/tex]  

[tex]x = \frac {9 -{1}}{2}=4[/tex]

[tex]x=4[/tex]

The factored form would be

[tex]y= (x-4)(x-5)[/tex]

Part 2:

We use the formula to find the x coordinate of the vertex of a parabola

[tex]V_{x}=\frac{-b}{2a}[/tex]

[tex]y = x^{2}  -9x+20[/tex]

a=1 b=-9 c=20

[tex]V_{x}=\frac{9}{2}[/tex]

Now we substitute the value of x in [tex]y = x^{2}  -9x+20[/tex] to find the value of the coordinate y of the vertex

[tex]y = \ (\frac{9}{2} )^{2}   -9(\frac{9}{2}) +20\\ y=  \frac{81}{4} -\frac{81}{2} +20\\ y= -\frac{1}{4}[/tex]

The vertex of the parabola is

Vertex:

[tex](\frac{9}{2}, - \frac{1}{4})[/tex]

Part 3:

the y-intercept is when the value of x = 0.

We substitute this value in [tex]y = x^{2}  -9x+20[/tex]

[tex]y = 0^{2}  -9(0)+20= 20[/tex]

The y-intercept is [tex]y=20[/tex]

Part 5:

A.

Between 4s and 5s

B and C.

Erin's photograph is taken at the lowest point of the roller coaster.

The lowest point of the parabola is the vertex.

The coordinate y of the vertex gives us the height and the coordinate x the time.

The height:

[tex]-\frac{1}{4}[/tex]

It is negative because it is below the point we take as zero.

The time:

[tex]\frac{9}{2}[/tex]s

[tex]a=6\sqrt{3}[/tex]

[tex]b=12[/tex]

[tex]c=6\sqrt{2}[/tex]

Step-by-step explanation:

step 1

Find the value of a

we know that

[tex]tan(60\°)=a/6[/tex]

Remember that

[tex]tan(60\°)=\sqrt{3}[/tex]

so

[tex]a/6=\sqrt{3}[/tex]

[tex]a=6\sqrt{3}[/tex]

step 2

Find the value of b

we know that

[tex]cos(60\°)=6/b[/tex]

Remember that

[tex]cos(60\°)=1/2[/tex]

so

[tex]6/b=1/2[/tex]

[tex]b=12[/tex]

step 3

Find the value of c

we know that

[tex]cos(45\°)=c/b[/tex]

[tex]cos(45\°)=c/12[/tex]

Remember that

[tex]cos(45\°)=\sqrt{2}/2[/tex]

[tex]c/12=\sqrt{2}/2[/tex]

[tex]c=6\sqrt{2}[/tex]

Answer:

x=2                x=-3

Step-by-step explanation:

4x2+3x=24-x

Subtract 24 from each side

4x^2 +3x -24 = 24-24 -x

4x^2 +3x -24 = -x

Add x to each side

4x^2 +3x+x -24 = -x+x

4x^2 +4x -24 = 0

Factor out a 4

4(x^2 +x -6) = 0

Divide by 4

x^2 +x -6 =0

Factor

What 2 numbers multiply to -6 and add to 1

-2*3 = -6

-2+3 =1

(x-2) (x+3) =0

Using the zero product property

x-2 =0            x+3 =0

x-2+2=0+2    x+3-3=0-3

x=2                x=-3

Answer:x=-3 , x = 2

Step-by-step explanation:

First move the expression ( 24-x) to the left.

This gives us 4x^2+3x+24-x.

Collect the like terms which gives us 4x^2+4x+24

4x^2+4x-24 = 0.  Divide both sides by 4.

x^2 + x-6 = 0

Factorise the expression so you get (x+3)(x-2)=0

Solve the equations x+3 = 0 and x-2=0

The final solutions are x=-3 and x=2.

Answer:

a = 2

Step-by-step explanation:

Let's find the equation of the line using the 2 points given.

Let's call -1 as x_1 and -5 as y_1

also, 4 as x_2 and 5 as y_2

The equation of line is :

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Let's plug the points and get the equation of the line:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\y+5=\frac{5+5}{4+1}(x+1)\\y+5=2(x+1)\\y+5=2x+2\\y=2x-3[/tex]

Now, to find a, we substitute a in x and 1 in y of the equation of the line we just got:

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

Answer: [tex]a=2[/tex]

Step-by-step explanation:

We know that this line passes through the point [tex](a,1)[/tex] where "a" is the  unknown x-coordinate of that point and 1 is the y-coordinate.

We also know that this line passes through the points (-1, -5) and (4, 5).

Then, in order to find the value of "a", we can plot the known points and draw the line (Observe the image attached).

You can observe in the image attached that the point whose y-coordinate is 1 is the point (2,1). Therefore, the value of "a" is:

[tex]a=2[/tex]

Answer:

y = - [tex]\frac{1}{3}[/tex] x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 3 ← is in slope- intercept form

with slope m = 3

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex], hence

y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation of the perpendicular line

To find c substitute (3, 1) into the partial equation

1 = - 1 + c ⇒ c = 1 + 1 = 2

y = - [tex]\frac{1}{3}[/tex] x + 2 ← equation of perpendicular line

Answer:

y = -1/3x + 2

Answer:

The company earned 68 billion dollars in the year 2008..

Step-by-step explanation:

This is because  the time t is the number of years since the END of 2008. The  time t = 0 at the end of 2008, so the earnings = 0^2 + 10(0) + 68 = 68 billion.

Answer:

option B

Step-by-step explanation:

A particular company's net sales is modeled by the expression (t² + 10t + 68)

Where t represents number of years since the end of year 2008.

In this expression 68 is the constant term which represents the earning of the company before 2008. or in year 2008.

The company earned 68 billion dollars in 2008.

Step-by-step explanation:

Rise over run is another term for slope, with we can use to derive a linear equation.

The term rise over run in technical terms is the change of y over the change of x.

To find the rise over run, subtract the y terms and divide that by the x terms.

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

You can use this to derive a linear equation as earlier mentioned by plugging in given points.

For example, a line passes through (3,4) with a rise over run of 3.

[tex]y=mx+b[/tex]

[tex]4=3(3)+b[/tex]

[tex]4=9+b[/tex]

[tex]b=-5[/tex]

So therefore the y intercept is -5, and the equation is [tex]y=3x-5[/tex]

Answer:

Age of Jacob is 10 years.

Step-by-step explanation:

Let the age of Jacob = x years and age of Kinsley = y years

Then by first statement " Kinsley's age is 7 years less than twice of Jacob's age"

y = 2x - 7

By second statement " Kensley is 13 years old "

y = 3 years

By putting y = 13 years in the equation

13 = 2x - 7

2x = 13 + 7

2x = 20

x = [tex]\frac{20}{2}[/tex] = 10 years

Therefore, age of Jacob is 10 years.

L = 4d + 54

when d = 31 days

L = 4(31) + 54

L = 124 + 54

L = 178 miles

Step-by-step explanation:

The length of the road after 35 days of construction is 76 miles.

The length of the road after 35 days can be calculated using the given function L(d) = 41 + d, where L represents the length in miles and d represents the number of days of construction. To find the length after 35 days, we substitute d = 35 into the function.

L(35) = 41 + 35

L(35) = 76

Therefore, the length of the road after 35 days of construction is 76 miles.
