let missing num be x ,

0.2 + x = 4.7

or, x = 4.7 - 0.2

In homer run derby competition there were 32 home rinse hit out of 124 hits approximately what percent of hits were home runs
RoseWind [281]

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.

\text{Formula for percentage }=\frac{\text{Number of hit by home run}}{\text{Total number of hits}}\times 100

Number of home runs hit = 32

Total number of hit = 124

Now we calculate the percentage

\%=\frac{32}{124}\times 100\approx 26

Thus, 26% of hits were home runs.

If f(x)=4arctan(7x), find f'(x). Find f'(4).
Pachacha [2.7K]

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)
