Answer:
m(c(a)) = 4.8875a can be used to find the marked-up price of a marble countertop depending on the area
Step-by-step explanation:
We are given that The cost for the raw materials of marble countertops, C s can be represented by the function c(a) = 4.25a --------1
a = area of the countertops.
we are also given that The retail markup, m, can be represented by the function m(c) = 1.15c.
We are supposed to find function can be used to find the marked-up price of a marble countertop depending on the area?
Marked up price function : m(c) = 1.15c.
Substitute the value of c form 1
Marked up price function of a marble countertop depending on the area:
m(c(a))=1.15(4.25 a)
m(c(a))= 4.8875 a
So, Option 1 is true
Hence m(c(a)) = 4.8875a can be used to find the marked-up price of a marble countertop depending on the area
Answer:
2x
Step-by-step explanation:
Just solve the function operation:
f/g=(2x/2x+1)/(1/2x+1) = 2x since (2x/1)/(2x+1/2x+1) simplifies to 2x/1 the answer is 2x
Answer:
(1, 0)
Step-by-step explanation:
To find the vertex of a quadratic function use the formula: x = -b/2a to find the x-value, which is "h" in (h, k).
The a-value is 2 and the b-value is -4. Substitute these values into the formula to find the x coordinate of the vertex.
Two negatives make a positive so the -(-4) becomes a 4, and 2 * 2 is 4.
- x = 4/4 which simplifies to 1.
To find the y-coordinate (k) substitute 1 for x into the original equation.
Evaluate the exponent.
Multiply 2 and -4 by 1.
Simplify by combining like terms.
You have x = 1 and y = 0, which is (x, y) ⇒ (h, k) so the vertex coordinates are (1, 0).
