Answer:

Pretty sure it's 38 ft^2

Step-by-step explanation:

Formula for circles=πr^2

So radius is 3.5 because radius is half the diameter

so 3.5^2=12.25

And 12.25 times 3.14 is your answer

Area = 3.14(r)^2
3.14(3.5)^2
=38.465
=38.5 (rounded)

Explain how the graph of y=-3tan(1/2x) is related to the graph of the basic trigonometric function y =tan x
Colt1911 [192]
The shapes of the 2 graphs are the same.  However, because x has a fractional coefficient between 0 and 1, the period of the graphed function is twice as long (that is, 2pi instead of pi), and the graph has been reflected about the x-axis and then stretched vertically by a factor of 3.

Find the average rate of change for the function f(x)=32 + 25
mixas84 [53]

given the function, there is no independent variable, x. Because of that your equation remains constant at the y axis, where you get f(x)=57. This means that for any input of x you’ll get 57 as the output. Because youre looking for average rate of change, you would use delta y/ delta x.

(2,57) and (6,57)

When you solve for change between the y and x, you get (57-57)/(6-2
) which ultimately gives you an average rate of change of 0.
