Answer:

Each side of the photocopy of the picture is  enlarged by a factor of 2.

Step-by-step explanation:

A picture is photocopied by using a scale factor of 2.

This actually means that the dimensions of the picture are multiplied by a factor 2.

For example, if the width and the height of a photograph are w and h respectively and when photocopied by using a scale factor of 2, then the final width and height of the copy will become 2w and 2h.

Hence, each side of the photocopy of the picture is enlarged by a factor of 2. (Answer)

An engineer needs to determine the distance across a river without swimming to the other side. The engineer notices a tree on th
nasty-shy [4]

Answer:

Step-by-step explanation:

The engineer can use a clinometer to measure the angle of elevation of the top of the tree. Let the height of the tree be represented by x, the she could determine the distance across the river, d, by applying the trigonometric function.

Tan θ = \frac{opposite}{adjacent}

           = \frac{x}{d}

the the distance, d = x ÷ Tan θ

Assume the angle of elevation of the top of the tree is 30^{o}, and the height of the tree is 10 m, then the distance, d, across the river would be;

d = \frac{10}{0.5774}

  = 17.3190

d = 17.32 m

The sketch to the explanation is attached to this answer for more clarification.

Calculate the slope between the two points: (7, –4), (7, 8)
Valentin [98]

Answer:

undefined

Step-by-step explanation:

We can find the slope by using the formula

m = (y2-y1)/(x2-x1)

m = (8 - -4)/97-7)

   = (8+4)/(7-7)

   = 12/0

We cannot divide by 0 so the slope is undefined

Which of the following inequalities is equivalent to 3-(w+2)&gt;4+2w
Kay [80]

3 - w - 2 > 4 + 2w  \\  - w - 2w > 4 + 2 - 3 \\  - 3w > 6 - 3 \\   \frac{ - 3w}{ - 3}  >  \frac{3}{ - 3} \\ w <  - 1
The sign at the end changes because both sides of the equation are being divided by a negative number.
