Let's say you are in Monument Valley and decided to measure the height of a rock formation using the method you learned from the workbook. The distance from your eyes to your finger is 23 inches. When you look
2
through your fingers at the rock, the gap between your fingers is of an inch. You know that you are about 6
miles from the rock. According to this information, approximately how tall is that rock formation? Find your
answer in miles (round your answer to the nearest hundredth), then convert it to feet (round it to the nearest
tenth).

The answer is "0.163 miles and 860.64 feet"

Step-by-step explanation:

Length between all the finger and the eyes = 23 inches  

Length between fingers = 3/4 inches = 0.75 inches    

Length between all the person as well as the rock = 5 miles

Length of the shape of rocks =?  

The height of an object can be found, as we can see from the above form, using the distance between both the fingertips, its length between all the eyes and thus the fingertips, or the length between the person is calculated by the given formula:    

calculating the height of rock:

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
