Answer:
10)$38.50
11)D
Step-by-step explanation:
10) n = no. of rides
f(n) + g(n) = 1 + 2.5n
when n=15, 1 + 2.5(15)
= $38.50
11)f(x) = 4x³+3x²-5x+20
g(x) = 9x³-4x²+10x-55
(g-f)(x)=9x³-4x²+10x-55-(4x³
+3x²-5x+20)
= 9x³-4x²+10x-55-4x³
-3x²+5x-20
= 5x³-7x²+15x-75
(Correct me if i am wrong)
The solution to what you put down is 1,3
What is asked in the problem is simply the volume of the solid rubber ball. The volume of sphere given the diameter may be calculated by,
V = πd^3 / 6
Substituting the given value of diameter,
V = (π x 3³) / 6 = 9π/2 or 14.14
Thus, one needs approximately 14.14 in³ of material.
The 4 is in the ten thousands place
Answer:
x=13
Step-by-step explanation:
I guess the angles are supplementary,Which means they have a sum of 180°.
11x - 15+5x-13=180
16x-28=180
16x=208
x=13
