Answer: x^2-2x+8
Step-by-step explanation:
its does not factor any more
its already in its lest form so therefore
the answer is x^2-2x+8
Hope this helps :)
Look at the picture.
![\cos 36^\circ = \frac{x}{12} \\ 0.809 \approx \frac{x}{12} \\ 0.809 \times 12 \approx x \\ x \approx 9.708](https://tex.z-dn.net/?f=%5Ccos%2036%5E%5Ccirc%20%3D%20%5Cfrac%7Bx%7D%7B12%7D%20%5C%5C%0A0.809%20%5Capprox%20%5Cfrac%7Bx%7D%7B12%7D%20%5C%5C%0A0.809%20%5Ctimes%2012%20%5Capprox%20x%20%5C%5C%0Ax%20%5Capprox%209.708)
The base of the ladder is approximately 9.708 feet from the tree trunk base.
The equation of the function is f"(x) = 2x^2 - 3
<h3>How to determine the equation?</h3>
The parent function is given as:
f(x) = x^4
When it is stretched vertically by a factor of 2, the rule is
f'(x) = 2f(x)
So, we have
f'(x) = 2x^2
When shifted down 3 spaces, the rule is
f"(x) = f'(x) - 3
So, we have:
f"(x) = 2x^2 - 3
Hence, the equation of the function is f"(x) = 2x^2 - 3
