A rectangular beam is to be cut from a cylindrical log of diameter 12 in. (a) Find the cross-sectional area of the beam as the function of where is as shown in the figure.
A(O) =
(b) Find the maximum cross-sectional area of such a beam. [Hint: Use the fact that sinu achieve its maximum value at
u= pi/2.]
_in. 2

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
