Answer:

The answer to your question is letter D. x = 64

Step-by-step explanation:

Equation

log x 8 = 0.5

Express the log as a exponential equation

x $x^{0.5}$ = 8

Express the power as a fraction

$x^{1/2} = 8$

$\sqrt{x^{2}}$

Look for a number which squared root is 8

$\sqrt{64} = 8$

Then

x = 64

Which basic trigonometric identity would you use to verify that tan x cos x =sin x

True [87]

Answer:

$\huge\boxed{\tan x=\dfrac{\sin x}{\cos x}}$

Step-by-step explanation:

$\tan x\cos x=\sin x\\\\\tan x=\dfrac{\sin x}{\cos x}\\\\\text{Therefore}\\\\\tan x\cos x=\dfrac{\sin x}{\cos x}\cdot\cos x\qquad\text{cancel}\ \cos x\\\\\tan x\cos x=\sin x\\\\\text{For}\ x\neq\dfrac{\pi}{2}+k\pi},\ k\in\mathbb{Z}$
