28 is 4 times 7, so we will rewrite it like that.
7 is 7 times 7, so we will rewrite it like that.
So the simplest form is,
G(h(x))
g(x^2 -2)
4(x^2 - 2) + 1
4x^2 - 8 + 1
4x^2 - 7
Answer:
x=-7±√97/4
Step-by-step explanation:
-7±√97
______
4
Answer:
8
Step-by-step explanation:
The area of a circle with twice the radius is 4 times the area of the smaller circle. If John's hours are proportional to area, we expect it will take him 4 times as long for the larger area.
John can expect to take 8 hours cutting the grass in the larger lawn.
___
The area of a circle with radius r is ...
A = πr²
The area of a circle with radius 2r is ...
π(2r)² = 4πr² = 4A . . . . . 4 times the area of the smaller circle
Answer:
Step-by-step explanation:
In the absence of additional information, will assume rotation is about the origin.
A 180° rotation about the origin has the equation
(x,y) => (-x,-y)
Therefore
R(-10, 5.6) => R'(10, -5.6)
S(0, 7) => S'(0, -7)
T(-6, -34) => T'(6, 34)
