If f(x) = 21 + 3sqrt(x+12) and g(x) = 2x^2+ 5, compute the composition (f ∘ g)(4).

(f ∘ g)(4) =

sqrt= square root of what’s in ( )

42

Step-by-step explanation:

g(4) = 2x^2+5

= 2(4)^2+5

= 2(16)+5

= 32+5

= 37

f(g(4)) = 21+3sqrt(x+12)

= 21+3sqrt(37+12)

= 21+3sqrt(49)

= 21+3(7)

= 21+21

= 42

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
