Answer:
1/4 or .25
Step-by-step explanation:
Answer:
26% of hits were home runs.
Step-by-step explanation:
In homer run derby competition there were 32 home rinse hit out of 124 hits approximately.
We need to find what percentage of hits were home runs.

Number of home runs hit = 32
Total number of hit = 124
Now we calculate the percentage

Thus, 26% of hits were home runs.
f'(x) = (4 arctan(7x))'
f'(x) = 4 (arctan(7x))'
By the chain rule,
f'(x) = 4/(1 + (7x)^2) * (7x)'
f'(x) = 28/(1 + 49x^2)
and hence
f'(4) = 28/(1 + 49*16) = 28/785
In case you're not sure about the derivative of arctan: If y = arctan(x), then x = tan(y). Differentiating both sides with respect to x gives
1 = sec^2y y' = (1 + tan^2y) y' = (1 + x^2) y'
==> y' = 1/(1 + x^2)
