[tex]Time = 17.143\ mins[/tex] -- When going

[tex]Time = 40\ mins[/tex] -- When coming back

Step-by-step explanation:

Given

[tex]Speed\ to = 7mi/hr[/tex]

[tex]Speed\ from = 3mi/hr[/tex]

[tex]Distance = 2\ mi[/tex]

Required

Determine time taken to your friend's house

Determine time taken from your friend's house

Distance is calculated as:

[tex]Time = \frac{Distance}{Speed}[/tex]

From the question, we understand that:

[tex]Distance = 2\ mi[/tex]

When going:

[tex]Speed\ to = 7mi/hr[/tex]

So, we have:

[tex]Time = \frac{2mi}{7mi/hr}[/tex]

[tex]Time = \frac{2}{7}hr[/tex]

Express in Minutes

[tex]Time = \frac{2}{7} * 60[/tex]

[tex]Time = \frac{120}{7}[/tex]

[tex]Time = 17.143\ mins[/tex]

When coming back:

[tex]Speed\ from = 3mi/hr[/tex]

[tex]Time = \frac{2mi}{3mi/hr}[/tex]

[tex]Time = \frac{2}{3}hr[/tex]

Express in Minutes

[tex]Time = \frac{2}{3} * 60[/tex]

[tex]Time = \frac{120}{3}[/tex]

[tex]Time = 40\ mins[/tex]

Answer:

88

Step-by-step explanation:

[tex]\sqrt{(64)(121)}\\\sqrt{64} \sqrt{121} \\(8)(11)\\88[/tex]

The square root of 64×121 is 88.

Square root is a factor of a number that, when multiplied by itself, gives the original number.

According to the given question

We have to find the square root of 64 × 121

The prime factorization of 64 is 2 × 2 × 2 × 2 × 2 × 2

And the prime factorization of 121 is 11 × 11.

Therefore the square root of 64 × 121 is given by

[tex]\sqrt{(64)(121)} =\sqrt{(2)(2)(2)(2)(2)(2)(11)(11)} = (11)(2)(2)(2)=88[/tex]

Hence, the square root of 64×121 is 88.

Answer:

Dilate circle A by a scale factor of 4. (c)

Step-by-step explanation:

HOPE THIS HELPS!!!

The steps will help show that circle A is similar to circle B is Dilate circle A by a scale factor of 4.

The correct option is (C).

Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.

Circle A has center of (0, 4) and a radius of 6

circle B has a center of (−3, 5) and a radius of 24.

The radius of circle A is 6 cm and radius of circle B is 24 cm, which 4 times the radius of circle A.

We know, Dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller.

This transformation produces an image that is the same as the original shape.

Thus, Dilate circle A by a scale factor of 4.

Answer:

x = 45°

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 8 ( number of sides of an octagon ) , then

sum = 180° × 6 = 1080°

the interior angles of a regular octagon are congruent , so

∠ ABC = 1080° ÷ 8 = 135°

x and 135° are adjacent angles on a straight line and sum to 180° , then

x = 180° - 135° = 45°

The riders experience free fall for about 3.12 seconds.

Step-by-step explanation:

Find t when  h = 105

105= [tex]-16t^{2} +256[/tex]

0= [tex]16t^{2}[/tex] +160

0 = -16([tex]t^{2}[/tex]-10)

[tex]t^{2}[/tex] - 10 = 0

[tex]t^{2}[/tex] = 10

[tex]t = \sqrt{10}[/tex]

The riders experience free fall for about 3.16 seconds.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To find how long the riders experience free fall, we need to find the time when the height is 105 feet above the ground.

So, we need to solve the equation:

-16t² + 265 = 105

Adding 16t² to both sides, we get:

16t² = 160

Dividing both sides by 16, we get:

t² = 10

Taking the square root of both sides, we get:

t = ±3.16

Since we are only interested in the positive value of t, we can round 3.16 to the nearest hundredth to get:

t = 3.16 seconds

Therefore,

The riders experience free fall for about 3.16 seconds.

x = 24

Step-by-step explanation:

First, substitute x = -6y into the top equation:

-6y + 3y = 12

-3y = 12

Divide both sides by -3, and you get:

y = -4

Now, you plug in the y value to the second equation:

x = -6(-4)

x =24

Given :
