Answer:

f(x) = 11x^2 + 12x - 12

g(x) = 12x^2 - 11x + 11

find g(f(3))

I'm not sure if i did everything correct, I came up with g(f(3)):31,734. I'd just like to know if this is right, and if not I'd like to see the steps so I know what I did wrong, thank you!

If you place a 26-foot ladder against the top of a 10-foot building, how many feet will the bottom of the ladder be from the bot

True [87]

Answer:

24 foot

Step-by-step explanation:

We are given that

Length of ladder=26 foot

Height of building=10 foot

We have to find the distance between the bottom of ladder and the bottom of building.

Pythagorus theorem:

$(Hypotenuse)^2=(Base)^2+(Perpendicular\;side)^2$

We have hypotenuse =AC=26 foot

Perpendicular side =AB=10 foot

Base=BC

Substitute the values in the given formula

$(26)^2=(10)^2+(BC)^2$

$676=100+(BC)^2$

$(BC)^2=676-100=576$

$BC=\sqrt{576}=24$ (Take positive because length is always positive)

BC=24 foot

Hence, the bottom of the ladder will be 24 foot from the bottom of the building.
