Circumference = 10pi
Radius = 10/2 = 5
Area = pi x 5^2 = 25pi
Answer:
When f(x) is 0, then x is -1.8.
Step-by-step explanation:
To find this, you simply have to look for the place where the line crosses the x axis. This is where y (or f(x)) is equal to 0. Since this graph only crosses that axis at x = -1.8, that is the number we are looking for.
Answer:
(5 t ) cubed = 5 cubed . t cubed = 125 t cubed applies the power of a product rule to simplify (5 t) cubed ⇒ 3rd answer
Step-by-step explanation:
Let us revise some rules of exponents
× =
×÷ =
=
= .
To simplify
∵ 5t means 5 × t
∵ Both of them are cubed
- Use the 4th rule above
∴ =
∵ (5)³ = 5 × 5 × 5 = 125
∴ = = 125 t³
(5 t ) cubed = 5 cubed . t cubed = 125 t cubed applies the power of a product rule to simplify (5 t) cubed
First start in the parentheses. (4+5) = 9 and (3+4)+7. Then 3+9 = 7+5. Both of those = 12.
The answer is 12:15
The only thing you have to do to get this answer is remove the zero of the number.
