Answer:

[tex]\displaystyle n^3-\frac{1}{n^{2}}[/tex]

Step-by-step explanation:

Exponents Properties

We need to recall the following properties of exponents:

[tex](a^x)^y=(a^y)^x=a^{xy}[/tex]

[tex]\displaystyle a^{-x}=\frac{1}{a^x}[/tex]

We are given the expression:

[tex]2^m=n[/tex]

We need to express the following expression in terms of n.

[tex]8^m-4^{-m}[/tex]

It's necessary to modify the expression to use the given equivalence.

Recall [tex]8=2^3 \text{ and }4 = 2^2[/tex]. Thus:

[tex](2^3)^m-(2^2)^{-m}[/tex]

Applying the property:

[tex](2^m)^3-(2^m)^{-2}[/tex]

Substituting the given expression:

[tex]n^3-n^{-2}[/tex]

Or, equivalently:

[tex]\mathbf{\displaystyle 8^m-4^{-m}= n^3-\frac{1}{n^{2}}}[/tex]

1.15 is the answer

Step-by-step explanation:

Answer:

100 sq m

Step-by-step explanation:

if you fill in the shape to be a big rectangle it will be 8 x 22 =176 sq m

then the little piece on the left that is taken out is 2 x 2 = 4 sq m

the piece on the right is 6 x 12 = 72 sq m

so subtract them from the big rectangle

176 - 4 - 72 = 100 sq m

Answer:

100m^2

Step-by-step explanation:

To do this we need to break the shape into sections as illustrated in the picture I attached, I color coded the squares to make it easier to explain. Now we just find the area of each shape and add them all together.

Area= base•height

So for the purple shape:

6•2=12

Orange:

8•8=64

Green:

2•12=24

In total:

12+64+24=100

And since it's area it would be in square units which just means it'd look like this:

[tex] {100m}^{2} [/tex]

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Answer:

the answer is 144 folders

Step-by-step explanation:

you have to convert the ft of the file cabinet to inches. so the cabinet is 12 in wide, 36 in deep and 36 in tall. the volume of it is 15,552 cu in. each folder is 108 cu in. divide 15,552 by 108 = 144 folders can fit in the cabinet. sorry my pic is messy.

I hope this helped and good luck!

Answer: Distance= 450km

Step-by-step explanation:

90 times 5= 450

=5^6/5^4

=5^(6-4)

=5^2 ANSWER..

Answer:

The answer is undefined.

Step-by-step explanation:

The x will never change, no matter what the y is, so the answer will always be undefined.

Answer:

YES you are right

Step-by-step explanation:11 squared equals 121

Answer:

y=-1/2x+2

the y-intercept is at 2 and the slope is -1/2

meaning the y coordinates with move down 1 while the x coordinates will move 2 in a positive (right) direction

Answer:

a

Step-by-step explanation:

4x+9y= -108

4(0)=9y= -108

9y= -108

-108/9

y- intercept= -12

Answer:

92,776

Step-by-step explanation:

I have 5 digits. My 9 is worth 9*10,000. My 2 is worth 2 thousand. One of my 7s is worth 70. The other is worth 10 times as much. My other digit is a 6. What number am I?

My 9 is worth 9*10,000 = 9 * 10,000

= 90,000

My 2 is worth 2 thousand = 2,000

One of my 7s is worth 70 = 70

The other is worth 10 times as much = 70 * 10

= 700

My other digit is a 6 = 6

The number is

90,000 + 2,000 + 700 + 70 + 6

= 92,776

Answer:

C. Infinitely many solutions

Step-by-step explanation:

Answer:

INFINITE SOLUTIONS

Step-by-step :(examples)

any value of x makes the equation true

true for all= infinite solutions

one solution= x=30

no solution= 7=0

Answer:

x = 18

y = 54

Step-by-step explanation:

A straight line equals 180 degrees.

Since Lines CD and AB are straight, we can deduce that the angle 3x = 2x + angle AN.

Because there is a right angle, we can subtract 90 -72 = 18.

18 + 2x = 3x

18 = x

A straight line equals 180 degrees. Once we figure out that x = 18, we can figure out y by plugging in x and then subtracting your answer from 180 degrees.

Step-by-step explanation:

because 20+5t=20+5t even if you put any number as the variable

Answer:

Step-by-step explanation:

Turn

Just turn the percentage into a decimal, in this case turn 20% into the decimal form .20.

Multiply

Multiply the decimal by the dollar.

.20 x 30 = 6$.

This applies to other questions similar to this. Turn the percentage into a decimal.

102% of 50$

102% = 1.02

1.02 x 50 = 51 $

3% of 8$

3% = 0.03

0.03 x 8 = 0.24 $

Answer:

A
