Answer:
A, B, D, F
Step-by-step explanation:
Given
f(x) = (x + 3)(x - 1)(x - 2)(x + 2)
To find the zeros let f(x) = 0, that is
(x + 3)(x - 1)(x - 2)(x + 2) = 0
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3 → B
x - 1 = 0 ⇒ x = 1 → F
x - 2 = 0 ⇒ x = 2 → D
x + 2 = 0 ⇒ x = - 2 → A
I’m pretty sure this is like a more personal question so you should answer it.
Answer:
c
Step-by-step explanation:
<span>Circumference of a circle = Diameter × pi
Circumference of a circle = 40 cm × 3.14
<u>Circumference of the wheel = 125.6 cm
</u>
1 Km = 1000m
</span>Circumference of the wheel × 1000m = The number of revolutions
125.6 × 1000m = 125600
<u><em>
</em></u>
The wheel would make <u>
125600 revolutions</u>
if the bike travels 1 km.
