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

Please answer ASAP! Compare and contrast the graphs of y < -x + 2 and y > -x + 2.
VikaD [51]
The greater than and less than equal signs determine which way the graph is shaded. The graphs follow the same line but are shaded in different directions. y<-x+2 is shaded below the line because the sign is less than (<). y>-x+2 is shaded above the line because the sign is greater than (>).

The legs of a right triangle are 10 centimeters and 24 centimeters long. What is the length of the hypotenuse?
Rina8888 [55]
A² + b² = c²

Where a and b are the legs and c is the hypotenuse

So, plug in 10 for one of the legs and 24 for the other leg

c will be left blank because that is what you are trying to find, the hypotenuse

10² + 24² = c²

100 + 576 = c²

676 = c²

Take the square root of both sides of the equation to isolate c

√676 = √c²

Square of c and the square root cross out on the right

Take the square root of 676

c = 26

So, the length of the hypotenuse is 26 centimeters

Volume cylinder pi 3.14 d=12 cm h = 6cm d=2r
alexira [117]

Answer:

678.24cm³

Step-by-step explanation:

Volume of cylinder = # r² h

Where # = 3.14

r = radius = d/2 = 12/2 = 6cm

h = 6cm

Therefore

Volume = #r²h

= 3.14 × 6² × 6

= 3.14 × 36 × 6

= 678.24cm³

a man buys a dozen cameras for $1800. He sells them at a profit of $36 each. Express his profit as a percentage of his selling p
Helga [31]

First of all, we need to deduce the price of a single camera:

\dfrac{1800}{12}=150

Now, we know that he profits 36 dollars from each camera. So, we are asking: which percentage of 150 is 36? We have

36 = 150\cdot\dfrac{x}{100}

This equation literally says: 36 is x-percent of 150. And we need to solve for x:

x=\dfrac{36\cdot 100}{150} =24
