You have to find out 300 or less customers per day
<span>d = q + 10
10d + 25q = 345 cents
----
Substitute for "d" and solve for "q";
10(q+10) + 25q = 345
35q + 100 = 345
35q = 245
q = 7 (# of quarters)
---
Since d = q+10, d = 17 (# of dimes)

Parabola equation with a vertex at (h, k) is given by y = a(x - h)^2 + k
For the give parabola, y = a(x - 4)^2 - 3
y = a(x^2 - 8x + 16) - 3
At (5, -6)
-6 = a((5)^2 - 8(5) + 16) - 3 = a(25 - 40 + 16) - 3 = a - 3
a = -6 + 3 = -3
Therefore, the coefficient of the squared expression is -3.
Answer:
B and C
Step-by-step explanation:
The way I got these answers was by using pythagorean theorem since all right triangles must be able to be used in the pythagorean theorem
