Answer:

The answer to your question is: - 7

Step-by-step explanation:

3125 = (- 1 - 18t) ⁵/³

(3125)³ = ( -1 - 18t)⁵

(3125)³/⁵ = - 1 - 18t

125 = - 1 - 18t

125 + 1 = - 18t

126 = - 18t

t = 126 / -18

t = -7

3125³ = 3.0518 x 10¹⁰

$\sqrt[5]{3.0518 x 10¹⁰}$ = 125

A) $(tanx-4)(9sin^2x-1)=0\\\\\\$

$9sin^2x-1=0\\\\sin^2x=\frac{1}{9} sinx=\frac{1}{3}$ or $sinx=\frac{-1}{3}$

OR $tanx=4\\$

$3sin2x=3.2.sinx.cosx\\\\6.sinx.cosx-4.sinx= 2sinx.(3cosx-2)=0\\\\3.cosx=2 cosx=\frac{2}{3}$
