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

True or false: When a figure on a coordinate grid is translated down and to the right, the vertex with the largest y-coordinate
Montano1993 [528]

Answer:

  • True

A GE Lightbulb is suppose to last for 1200 hours. In fact light bulbs of this type last only 1,185 hours with a standard deviati
Andre45 [30]
This can be solved using the formula for t test which is = x - mu over standard deviation divided by the square root of the number of samples. In this case, it is 1185 - 1200 over 70 divided by square root of 100 which give us a value of 2.14 which is equal to .9839 in area. Only rarely, just over one time in a hundred tries of 100 light bulbs, would the average life exceed 1200 hours.

Elena is 56 inches tall. What is her height in centimeters? (Note: 100 inches = 254 centimeters) What is her height in meters?
LUCKY_DIMON [66]

Answer:

142.24cm

Step-by-step explanation:

If 100 inches = 254cm then if you do 254/100 you will get how many cm are in an inch. 254/100 = 2.54

This means there are 2.54 cm in an inch. Multiply 2.54cm by 56 inches and you get how many cm are in 56 inches which is 142.24cm. This means Elena is 142.24 cm tall.
