Answer:
see below
Step-by-step explanation:
f(x)= -0.08x(x^2-11x+18)
Factor
f(x)= -0.08x(x-9)(x-2)
Using the zero product property to find the zeros
0= -0.08x(x-2)(x-9)
-0.8x =0 x-2 =0 x-9 =0
x=0 x=2 x=9
Multiply out
f(x) = -0.08 x^3 + 0.88 x^2 - 1.44 x
The highest power is x^3
f(-∞) = -0.08( -∞)^3 = - ( -∞) = ∞
As x goes to -∞ f(x) goes to +∞
f(∞) = -0.08( ∞)^3 = - ( ∞) = -∞
As x goes to ∞ f(x) goes to -∞

Answer:
a. 4/13, b. 1/2, c. 3/52, d. 8/13
Step-by-step explanation:
a.
aces in a deck: 4
face cards in a deck: 12
(4+12)/52 = 16/52 = 4/13
b.
even numbers in a deck: 26
26/52 = 1/2
c.
only 3 face cards that are diamonds
3/52
d.
reds in a deck: 26
face cards in a deck: 12
face cards that are red: 6
(26+12-6)/52 = 32/52 = 8/13
Answer:
7k
Step-by-step explanation:
Note that - (- 8k) = + 8k
Given
- k - (- 8k)
= - k + 8k
= 7k
