On circle OOO below, \overline{ZX} ZX start overline, Z, X, end overline is a diameter. The measure of \stackrel{\LARGE{\frown}}{ZY} ZY ⌢ Z, Y, start superscript, \frown, end superscript is 104^\circ104 ∘ 104, degrees. What is the measure of \angle OZY∠OZYangle, O, Z, Y? ^\circ ∘ degrees

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

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

mrb

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