No. -3=2(4)+1 simplifies down to -3=9 and that is not true

If you place a 100-foot ladder against the top of a 96-foot building, how many feet will the bottom of the ladder be from the bo

soldier1979 [14.2K]

X^2+y^2=z^2

x^2+96^2=100^2

x=sqrt(100^2-96^2)

x=28 so the distance from the base of the ladder and the base of the ladder is 28ft.

Hope this helps. Any questions please just ask. Thank you.

Find the indicated values, where

Rom4ik [11]

Answer:

option (b) is correct.

The value of $g(f(3)-2f(1))$ is 0.

Step-by-step explanation:

Given: $g(t)=t^2-t$ and $f(x)=1+x$

We have to find the value of $g(f(3)-2f(1))$

Consider the given function $f(x)=1+x$

First evaluate value of function f(x) at x = 3 and 1 then substitute it in $g(f(3)-2f(1))$ .

f(3) = 1 + 3 = 4

f(1) = 1 + 1 = 2

Substitute, we get

$g(f(3)-2f(1))=g(4-2(2))$

Solving further , we get,

$g(f(3)-2f(1))=g(4-4)=g(0)$

Now evaluate $g(t)=t^2-t$ at t = 0 , we get,

$g(0)=0^2-0=0-0=0$

Thus, value of $g(f(3)-2f(1))$ is 0.

Thus, option (b) is correct.
