Answer:

Either x = 2 or y = 6, depending on the original line

Step-by-step explanation:

So, if the original line is horizontal, our new line is vertical, and all vertical lines in a graph is x = some number. To pass through the point (2, 6), x has to equal 2, since the point's x-coordinate is 2.

On the other hand, if the original line is vertical, our new line is horizontal, which is y = some number. Our point's y-coordinate is 6, so our line should be that y = 6.

It's A, x=2. I hope i helped!!

Answer:

x = 12.5

Step-by-step explanation:

The given triangle is a right angle triangle.

We cannot use the Pythagoras theorem as the lengths of all sides are not known. We will use triangular ratios here to solve the given problem.  

As it is clear from the diagram that x is the hypotenuse of the triangle and 11 is the length of the base. We will use a ratio in which base and hypotenuse are used.

So,

cos ⁡θ= base/hypotenuse

cos⁡ 28=11/x

x=11/cos⁡28  

x=11/0.8829

x=12.45

Rounding off to nearest 10

x=12.5

Answer:

an inequality

Step-by-step explanation:

An inequality is the relation between two expressions that are not equal.  The symbols generally used are less than (<) or greater than (>), as in:

4 > 3 or 4 < 9

That means that each side of the symbol represents a value that  is different from the other side.  The relationship is described with the sign to indicate which side has a greater value.

If both sides have an equal value, then it's an equation.

Answer:

Part 2) Option D. yes; k = 1/4 and y = 1/4x

Part 6) Option D. y = 1/5x-1

Part 8) Option C. line b

Part 11) Option D. -1/5

Part 15) Option A. line a

Step-by-step explanation:

Part 2) we know that

A relationship between two variables, x, and y, represent a directly variation if it can be expressed in the form  [tex]y=kx[/tex]

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem the line passes through the origin

therefore

Yes. y varies directly with x

Let

A(4,1)

The constant k is equal to

[tex]k=y/x[/tex]

substitute

[tex]k=1/4[/tex]

the equation is equal to

[tex]y=(1/4)x[/tex]

Part 6) we know that

The y-intercept of the trend line is -1 (For x=0)

The slope of the trend line is positive

The x-intercept of the trend line is 5 (For y=0)

therefore

the equation is equal to

[tex]y=(1/5)x-1[/tex]

Part 8) we have

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

This is the equation of a line into point slope form

The slope is negative [tex]m=-2/3[/tex]

Pass through the point (0,-4) ----> y-intercept

The x-intercept is equal to

[tex]0+4=-\frac{2}{3}x[/tex]

[tex]x=-4*3/2=-6[/tex]

therefore

Is the line b

Part 11)

What is the slope of the line through the points (–2, –1) and (8, –3)?

we know that

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

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

substitute the values

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

[tex]m=\frac{-2}{10}[/tex]

simplify

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

Part 15) we have

[tex]y=3x-2[/tex]

The slope is positive [tex]m=3[/tex]

The y-intercept is -2 (For x=0)

The x-intercept is  (For y=0)

[tex]0=3x-2[/tex]

[tex]3x=2[/tex]

[tex]x=2/3[/tex]

therefore the line is a

Step-by-step explanation:

Having proven that the triangles are similar, we can write the proportion:

AP / CP = CP / MP

9 / CP = CP / 16

CP² = 144

CP = 12

Now, we can simply use Pythagorean theorem to find the other sides.

AC² = AP² + CP²

AC² = 9² + 12²

AC = 15

CM² = CP² + PM²

CM² = 12² + 16²

CM = 20

Answer:

A) The equation in factored form is (4t + 1)(t - 2) = 0

B) The solutions of the equation are t = -1/4 and t = 2

C) It will take 2 seconds for the rocket to hit the ground

Step-by-step explanation:

* Lets study the information in the problem

- A child launches a toy rocket from the top of a slide

- The equation of the motion is -16² + 28t + 8 = 0, where t is the time

 of rocket to hit the ground

* Now lets solve the problem

- At first simplify the equation

∵ -16t² + 28t + 8 = 0

∵ Al the terms have a factor 4

- Divide all terms by 4

∴ -4t² + 7t + 2 = 0 ⇒ multiply all terms by -1

∴ 4t² - 7t - 2 = 0

- Lets factorize

∵ 4t² = 4t × 1t ⇒ 1st term in the 1st bracket × 1st term in the 2nd bracket

∵ -2 = 1 × -2 ⇒ 2nd term in the 1st bracket × 2nd term in the 2nd bracket

∵ 4t + -2 = -8t ⇒ product of the extremes

∵ 1t × 1 = 1t ⇒ product of means

∵ -8t + 1t = -7t ⇒ middle term

∴ The factorization of 4t² - 7t - 2 is (4t + 1)(t - 2)

∴ (4t + 1)(t - 2) = 0

A) The equation in factored form is (4t + 1)(t - 2) = 0

- Lets use the zero product property to solve the equation

∵ (4t + 1)(t - 2) = 0

- Equate each factor by 0

∵ 4t + 1 = 0 ⇒ subtract 1 from both sides

∴ 4t = -1 ⇒ divide both sides by 4

∴ t = -1/4

OR

∵ t - 2 = 0 ⇒ add 2 for both sides

∴ t = 2

B) The solutions of the equation are t = -1/4 and t = 2

C) We can not accept the answer t = -1/4 because there is no negative

    value for the time

∴ The answer is t = 2 only

Step-by-step explanation:

The square root of an integer is rational only if that integer is a square number. The closest squares to 8 are 2^2 = 4 and 3^2 = 9. 8 is not a square number, so has an irrational square root.

The square root of 8 is an irrational number.

A square root is a mathematical operation that, when applied to a number, finds a value that, when multiplied by itself, equals the original number. For example, the square root of 25 is 5 because 5 x 5 = 25. It is denoted by the √ symbol. Whether the square root of 8 is a rational number or not can be determined by finding the square root and checking if it can be expressed as a fraction.

The square root of 8 is approximately 2.828, which is an irrational number because it cannot be expressed as a fraction. To further prove that it is irrational, we can use the prime factorization method and show that 8 does not have a perfect square factor.

Step-by-step explanation:

If Vanessa pulls out a 2 from the first bag, then the possibilities based on the second bag are:

X = 2*3 = 6

X = 2*4 = 8

X = 2*5 = 10

X = 2*6 = 12

Repeat this for the other values from the first bag.  If she pulls a 3, the possibilities are:

X = 3*3 = 9

X = 3*4 = 12

X = 3*5 = 15

X = 3*6 = 18

If she pulls a 4:

X = 4*3 = 12

X = 4*4 = 16

X = 4*5 = 20

X = 4*6 = 24

And finally, if she pulls a 5:

X = 5*3 = 15

X = 5*4 = 20

X = 5*5 = 25

X = 5*6 = 30

Of the 16 total combinations, 5 are greater than or equal to 12 and less than or equal to 15.

Therefore, P(12 ≤ X ≤ 15) = 5/16.

Answer:

Step-by-step explanation:

Set up a table for a distance = rate × time problem.  We are considering the trips taken on Monday and Tuesday.

                         d     =     r     ×     t

Monday

Tuesday

Now let's start filling in what we know.  First off, Fran went to her Mother's both days.  Unless her Mother moved overnight from Monday to Tuesday, the distance from Fran to her mom is the same both days, even though we don't know how far it is.  So we will just call that "d".

                           d     =     r     ×     t

Monday               d     =

Tuesday              d     =

Now we are told about the times it took to get there on both days.  Monday took 2.7 hours and Tuesday took 3 hours.  Filling in that:

                            d     =     r     ×     t

Monday                d     =           ×     2.7

Tuesday               d     =           ×     3

We're getting there.  Now let's look at rates.  Again, we don't know her rate (that's what we are solving for!) but we do know that she drove faster on Monday than Tuesday.  Tuesday she was 6 miles per hour slower than Monday.  Since we don't know Monday's rate, we will call it r.  Since we don't know Tuesday's rate, but only that it is 6 mph slower than Monday, we will call it r - 6

                            d     =     r     ×     t

Monday               d     =     r      ×     2.7

Tuesday               d     =    r-6   ×     3

Now we have our equations.  We know that d = rt.  Since the distances are the same, d = d, by the transitive property of equality, we can set the 2 expressions equal to each other:

2.7r = 3(r - 6) and solve for r:

2.7r = 3r - 18

-.3r = -18

r = 60

If r = 60, then that r value goes in for Monday.  That means that Tuesday is 60 - 6 which is 54

What was her average speed on Tuesday is 54 mph

Monday

Time = 2.7 hours

Date = r mph

Distance = 4.5r miles

Tuesday

Time = 3 hours

rate = r-6 mph

Distance = 3(r-6) miles

Hence:

Distance = distance

2.7r=3(r-6)

2.7r = 3r - 18

0.3r = 18

r =18/0.3

r 60 mph ( Monday rate)

r-6=60-3  (Tuesday rate)

r-6 = 54 mph (Tuesday rate)

Inconclusion  What was her average speed on Tuesday is 54 mph.

the rectangle

Step-by-step explanation:

the cylinder folds like a circle but it is not a circle.

A rectangular shape can be rotated about an axis to form a cylinder.

A cylindrical shape is a three-dimensional geometrical shape consisting of two parallel circular bases which are connected by some height h.

We know that cylinder has some height h and two base circles.

If we compare the curved part of the cylinder then we can see that its shape is similar to a rectangle.

The length of the rectangle is similar to the circumference of the circular base of a cylinder and the height of the cylinder with the breadth of the rectangle.

A regular polygon is defined to be a convex polygon with congruent sides and congruent angles.

Convex means that all interior angles are less than 180 degrees.  However, if all interior angles are equal, the polygon has to be convex.

Final answer:

A regular polygon is a convex shape with sides and angles that are all congruent, exemplified by the faces of an icosahedron or an equilateral triangle.

Explanation:

A regular polygon is defined to be a convex polygon with congruent sides and congruent angles. This means that all sides are the same length and all interior angles are equal in measure, which contributes to the polygon's symmetry. As an example from three-dimensional geometry, an icosahedron is a symmetrical, solid shape with 20 faces, each of which is an equilateral triangle.

The fully simplified product of (b-2c)(-3bc) has 2 terms and a degree of 3. The number of negative terms in the simplified product depends on the values of b and c, which are not provided.

When simplifying the expression (b-2c)(-3bc), we use the distributive property to multiply each term in the first parenthesis by each term in the second parenthesis. However, since the two terms -2c and -3bc will multiply to produce a term with a higher degree than b times -3bc, the simplified expression does not have 4 terms, but rather only 2 terms. The correct simplified form is -3b^2c + 6c^2. There are two terms, and the highest degree of any term, which is the sum of the exponents of the variables in that term, is 3 (b^2c having degree 3, since 2+1=3).

Therefore, the correct statements about the fully simplified product of (b-2c)(-3bc) are:

Explanation:

The altitude CH divides triangle ABC into similar triangles:

ΔABC ~ ΔACH ~ ΔCBH

Angle bisector AL divides the triangle(s) into proportional parts:

BL/BA = CL/CA

HD/HA = CD/CA

Of course, the Pythagorean theorem applies to the sides of each right triangle:

AH^2 +CH^2 = AC^2

DH^2 +AH^2 = AD^2

LC^2 + AC^2 = LA^2

AC^2 +BC^2 = AB^2

And segment lengths sum:

HD +DC = HC

AD +DL = AL

AH +HB = AB

CL +LB = CB

Solving the problem involves picking the relations that let you find something you don't know from the things you do know. You keep going this way until the whole geometry is solved (or, at least, the parts you care about).

___

We can use the Pythagorean theorem to find AH right away, since we already know AD and DH.

DH^2 +AH^2 = AD^2

4^2 + AH^2 = 8^2 . . . . . . . substitute known values

AH^2 = 64 -16 = 48 . . . . . . subtract 16

AH = 4√3 . . . . . . . . . . . . . . take the square root

Now, we can use this with the angle bisector relation to tell us how CD and CA are related.

HD/HA = CD/CA

4/(4√3) = CD/CA . . . . . substitute known values

CA = CD·√3 . . . . . . . . . cross multiply and simplify

Using the sum of lengths equation, we have ...

CH = HD +CD

CH = 4 + CD

From the Pythagorean theorem ...

AH^2 +CH^2 = AC^2

(4√3)^2 + (4 +CD)^2 = (CD√3)^2 . . . . . substitute known values

48 + (16 +8·CD +CD^2) = 3·CD^2 . . . . . simplify a bit

2·CD^2 -8·CD -64 = 0 . . . . . . . . . . . . . . . put the quadratic into standard form

2(CD -8)(CD +4) = 0 . . . . . . . . . . . . . . . . factor

CD = 8 . . . . . only the positive solution is useful here

Now, we know ...

∆ADC is isosceles, so ∠ACH = ∠CAD = ∠DAH = ∠CBA

CH = 8+4 = 12

AC = 8√3 . . . . . = 2·AH

Then by similar triangles, ...

AB = 2·AC = 16√3

BC = AC·√3 = 24

Where h is a constant such that:

If [tex]h> 0[/tex] then the graph of f(x) moves h units to the left

If [tex]h <0[/tex] then the graph of f(x) moves h units to the right.

In this case we have the function [tex]y = x ^ 2[/tex] and we know that 8 units are moved to the right. If you move 8 units to the right This means that

[tex]h <0[/tex] and [tex]h = -8[/tex]
