Answer: 608/3

using my program, it simplifies up to 1/3 pi (608), and it wants you to write it as 608/3 in the answer box. Haven't seen a correct answer for my schooling program yet, hope this helps :)

edit: brainly censors my schooling program for some reason? but i use e*genuity (hope you can figure out what that one means :) )

The shadow of a 60 foot pole is a 100 feet long. What is the angle of evaluation from the end of the shadow to the top of the po

Lilit [14]

Answer:

θ = 36.86°

Step-by-step explanation:

Given that,

The shadow of a 60 foot pole is a 100 feet long.

We need to find the angle of elevation from the end of the shadow to the top of the pole.

Height, h = 60 foot

Hypotenuse, H = 100 feet

Using trigonometry to find it.

$\sin\theta=\dfrac{\text{Height}}{\text{Hypotenuse}}\\\\\sin\theta=\dfrac{60}{100}\\\\\theta=\sin^{-1}(\dfrac{60}{100})\\\\\theta=36.86^{\circ}$

So, the angle of elevation is 36.86 degrees.

Answer:

-2x²(x + 1)(x - 4)

Step-by-step explanation:

Hello!

Factor:

$-2x^4 + 6x^3 + 8x^2$
$-2x^2(x^2 - 3x - 4)$ Take out GCF

Think: What numbers add up to -3 and multiply to -4?

Answer: -4 and 1

Continue:

$-2x^2(x^2 - 3x - 4)$
$-2x^2(x^2 - 4x + x - 4)$
$-2x^2(x(x - 4) + 1(x - 4))$ Factor by Grouping
$-2x^2(x + 1)(x - 4)$

The complete factored form is -2x²(x + 1)(x - 4)
