Evaluate the following expressions, and justify your answers. WhatPower1/3(9)

Mathematics
1 answer:
Galina-37 [17]4 years ago
3 0

Answer:

correct answer is -2

Step-by-step explanation:

given data  as per question

WhatPower1/3(9)

to find out

Evaluate the expressions WhatPower1/3(9)

solution    

so here  we know that whatpower mean exponent of equation so we get by given equation  

so

we know WhatPower1/3(9)  = -2

because  here

we know that   \frac{1}{3} * \frac{1}{3}  = \frac{1}{9}

but we want only 9

so \frac{1}{\frac{1}{3}} * \frac{1}{\frac{1}{3}}  = 9

so exponent is -2

so here we can say that

(\frac{1}{3})^{-2}  = 9

so that  the exponent  is here -2 of \frac{1}{3}  that become 9

so correct answer is -2

Select the functions that have a value of 0.
Sphinxa [80]

Answer:

<h2>cos90° = 0°, tan0° = 0°,</h2><h2>cos(-90°) = 0°, cot270° = 0°</h2>

Step-by-step explanation:

k\in\mathbb{Z}\\\\\sin x=0\iff x=180^ok\\\\\cos x=0\iff x=90^o+180^ok\\\\\tan x=0\iff x=180^ok\\\\\cot x=0\iff x=90^o+180^ok\\\\\csc x\neq0\ \text{for}\ x\in\mathbb{R}-\{180^ok\}\\========================\\\\\sin270^o\neq0\\\\\cos90^o=\cos(90^o+180^o\cdot0)=0\\\\\tan0^o=\tan(180^o\cdot0)=0\\\\\csc(-180^o)\neq0\\\\\cos(-90^o)=\cos(90^o-180^o)=\cos(90^o+180^o\cdot(-1))=0\\\\\cot270^o=\cot(90^o+180^o)=0
