Answer:
x^2(x-4) + 3(x-4)
(x^2 + 3)(x-4)
Step-by-step explanation:
X is minus 2
y is equal to 1
To understand the problem clearly, you have to illustrate it. Based on my understanding, the problem goes like this. Please refer to the picture. When the sun is high up in the sky, it causes a shadow to form. In the picture, this is represented by the bold horizontal line to the ground that measures 27.6 m. You want to find the angle of elevation of the sun, denoted as x°. With the height of the tree being 18 m, you create a right triangle. Therefore, we can apply the pythagorean theorems.
With respect to the unknown angle, you know the opposite side (18 m) and the adjacent side (27.6 m). So, it would be easier to use the tangent function.
tan x° = opposite/adjacent = 18/27.6
x = tan^-1 (18/27.6)
x = 33.11°
4.74/.06=79
19.44/.54=36
I used a calculator. You can change each decimal into a fraction to solve too.
Surface area is area so it's in^2 or inches squared
12 in=1 foot therfor
1in<1 foot
so therfor if we converted the surface area to feet, then the number would decrease, but the actual area would stay the same because we just converted the units, we didn't change the actuall area
therfor the answers are A and E
