Supplementary angles are two angles on a line that equal to 180°
Answer:
1) -43 2)-10
Step-by-step explanation:
so for the first one you would enter -9 into all of the x's
g(x)=4x-7
g(-9)=4(-9)-7 ( you would get -36, then you would minus y. so the answer is -43!)
g(-9)=-43
second one would be the same thing
g(x)=x^2-4x+11
g(-4)=-7^2-4(-7)+11
g(-4)=-10
Answer:
<h3><u>C≈131.97cm</u></h3>
A Area
1386cm²
Using the formulas
A=πr²
C=2πr
Solving forC
C=2√πA
=2·√π·1386
≈131.97344cm
