P = √ab
p² = ab
p²/b = a
a = p²/b
Answer:
60
Step-by-step explanation:
había multiplicado 4 y 15 espero que esto ayude
Take into account, that in general, a cosine function of amplitude A, period T and vertical translation b, can be written as follow:

In the given case, you have:
A = 4
T = 3π/4
b = -3
By replacing you obtain:

Hence, the answer is:
f(x) = 4cos(8/3 x) - 3
2u + 1 > -5/4u - 9
2u + 5/4u > -9 - 1
8/4u + 5/4u > -10
13/4u > -10
u > - 10 * 4/13
u > -40/13 or - 3 1/13 <=
Hello,
505/1 000 = ( 505 / 5 ) / ( 1 000 / 5 ) = 101/200
Bye :)
