Log\frac{}{2} 3=a, log\frac{}{2} 5=b. Express the following in terms of a and b (a) log\frac{}{2} 60.(b), log\frac{}{4} 0.2.(c), log\frac{}{3}25.

step-by-step explanation: 4 cause 2+2=4

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

regards,  

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

answer: you need to organize this better it does not make sense.

step-by-step explanation: ?

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
