S1/S2 = 1/16
Thus R1/R2 = 1/4
So V1/V2 = 1/64
Answer: 1/64
Answer:
(fog)(x)=6x-3
Step-by-step explanation:
In this problem, we are looking to find f of g of x. Simply put, we just have to <em>plug</em> g(x) into f(x). Whereever there is an x in f(x), we will <em>replace</em> with g(x).

Answer:
$1.20
Step-by-step explanation:
9.20 x 4 = 36.8
7.60 x 5 = 38
38 - 36.8 = 1.20
We know that the graph goes in units of 1.
We know that the roots are -1 and 4. (Just assume it's accurate and not off by 0.0000000001.)
We can set it up as an equation: -1(x+1)(x-4) = y (I added -1 because there are two parabolas that go through those points on the x-axis, and since this parabola is facing down, I must add a negative a value.
Then multiply (F.O.I.L. - First, Outer, Inner, Last)
x^2 -4x + x - 4 = -(x^2 - 3x - 4) = -x^2 + 3x + 4
Then using -(b/2a) solve for vertex: -(3/-2) = 3/2
Plug 3/2 back into the equation.
-(3/2)^2 + 3(3/2) + 4 = -9/4 + (9/2) + 4 = 25/4
The vertex would be: (3/2, 25/4)
Axis of symmetry would be: x = 3/2
Combined means to add so you are going to add anything over 1 because it says longer than 1
1 1/4 has 2 marks so you add 1 1/4 + 1 1/4 =
they have like denominators so you can add them together
1 + 1 = 2 and 1/4 + 1/4 = 2/4 which can be reduced to 1/2
so your answer is 2 1/2
