Which of these is equivalent to 1 over x to the power of 5 ? 1 fifth x negative x to the power of 5 x to the power of 5 x to the
Kisachek [45]

Answer:

x^-5 = x to the power of negative 5

Step-by-step explanation:

Which of these is equivalent to 1 over x to the power of 5 ?

Mathematically this is expressed as

(1/x)⁵

We have a rule when it comes to expressing power

(1/a)^b = a^-b

Hence, applying this rule to our question

(1/x)⁵ = (1/x)^5

= x^-5

This is written in words as:

x to the power of negative 5

luna has $50 when she got to the carnival. after 12 rides, she had $26. what was the price of each ride?
stellarik [79]

Answer:

<h2>$2</h2>

Step-by-step explanation:

Lets see how much money she spent first.

$50 - $26 = $24

Now that we know she spent $24 we can divide 24 by twelve which will tell us how much each ride costs

24 / 12 = 2

She spent $2 on each ride

The midpoint of AB is M (6,1). If the coordinates of A are (4, 8), what are the coordinates of B?
geniusboy [140]

Answer:

B = (8,-6)

Step-by-step explanation:

Given

A = (4,8)

M = (6,1) -- Midpoint

Required

Find B

This question will be solved using midpoint formula;

M(x,y) = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})

Where

A(x_1,y_1) = (4,8)

M(x,y) = (6,1)

Substitute these values in the midpoint formula;

(6,1) = (\frac{4 + x_2}{2},\frac{8+y_2}{2})

By comparison; we have:

\frac{4 + x_2}{2} = 6 -- (1)

\frac{8 + y_2}{2} = 1 -- (2)

Solving (1)

\frac{4 + x_2}{2} = 6

Multiply both sides by 2

4 + x_2 = 12

Subtract 4 from both sides

x_2 = 8

Solving (2)

\frac{8 + y_2}{2} = 1

Multiply both sides by 2

8 + y_2 = 2

Subtract 8 from both sides

y_2 = -6

Hence:

B = (8,-6)
