Answer:

(A-P)/PT = R

Step-by-step explanation:

A=P+PRT

Subtract P from each side

A-P=P-P+PRT

A- P = PRT

Divide each side by PT

(A-P)/PT = PRT/PT

(A-P)/PT = R

Write an expression that represents the area of the polygon shown below?
Alisiya [41]

Answer:

A = 5x + 12 (See explanation!)

Step-by-step explanation:

So, this "polygon" is really just two rectangles combined! With that in mind, remember that the area of a rectangle is base*height. Now, apply that to the problem. We know that the total length of the bottom base is 7, and 5 is the length of the second rectangle's base, so the 1st rectangle's base must be 7 - 5 = 2. The area of the 1st rectangle is then 6*2 = 12. The second rectangle's area is 5*x. So, if the area of the polygon is the sum of the two rectangles' areas, the expression you could use is:

5*x + 6* 2 = A

Simplify/Rewrite:

A = 5x + 12

(A is area, x is the unknown length in the diagram)

Hope this helps!

An eagle perched 40 ft up in a tree looks down at a 35 degree angle(angle of depression) and spots a vole. How far is the vole f
maria [59]

Answer:

X=49ft

Step-by-step explanation:

From the question we are told that:

Height of Eagle h=40ft

Angle of depression \theta=35\textdegree

 

Generally the trigonometry equation for diagonal X is mathematically given by

Cos\theta \textdegree=\frac{Adjacent}{Hypotenuse} }

Cos\theta \textdegree=\frac{h}{X} }

X=\frac{40}{Cos 35 } }

X=48.83ft

X=49ft
