Answer:

p^(a-1)

Step-by-step explanation:

The simplified expression can be seen in the picture attached below

As the factors have the same base, we just need to add or substract the exponents

p^(a-3+2) = p^(a-1)

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.

Gina has completed her CAD drawing and wants to take a print out. What final step must she take before taking the print out?

viktelen [127]

Answer:

D. delete all the layers created and retain only the final layer

Step-by-step explanation:

CAD (Computer aided design) drawing is used in designing 2 and 3 dimensional drawings. It uses some computer software such as the C++ programming which supports custom objects. It was also one of the earliest forms of computer aided design programs that could be used on personal computers.

The final steps in the CAD drawing involves the deletion of all the extra layers created as a result of measurements, and the retention of only the final layer. This final layer would give us the real shape we need,
