Answer:
Surface area of sphere = 4πr²
r = radius
and radius = diameter/2
radius = 13/2
= 6.5cm
Surface area = 4 × π × 6.5
= 26 × π
= 81.68
= 81.7cm²
Hope this helps.
Answer: -11 & 9
Step-by-step explanation: Coefficients are the numbers before the variables.
For this case we have the following expression:
^ 5sqrt4x ^ 2 ^ 5sqrt4x ^ 2
Rewriting the expression we have:
((4x ^ 2) ^ (1/5)) ((4x ^ 2) ^ (1/5))
For power properties we have:
(4x ^ 2) ^ (1/5 + 1/5)
(4x ^ 2) ^ (2/5)
Rewriting we have:
(16x ^ 4) ^ (1/5)
^ 5sqrt16x ^ 4
Answer:
^5sqrt16x^4
This occurs for the input(s) x where the outputs, f(x) and g(x), are equal. So here, f(x) = g(x) when x = 1, because 5 = 5.
