Why can’t you raise 0 to a negative exponent?

4 0

Step-by-step explanation:

To know this, you first have to know what a negative exponent is. A positive exponent multiplies the base by itself a given amount of times, but a negative exponent makes a fraction with 1 in the numerator and the base and exponent in the denominator. For example:

$2^{-2}$ = $\frac{1}{2^2}$ = $\frac{1}{4}$

So let's try to do the same thing with 0 with a negative exponent.

$0^{-2}$ = $\frac{1}{0^2}$ = $\frac{1}{0}$

This is a big no-no. You can never have 0 as the denominator since it is undefined. Therefore, you can't raise 0 to a negative exponent.

I really hope this helps you =)

If EFH = (5x + 1)°, HFG = 62°, and EFG = (18x + 11)°, find EFH

olga55 [171]

Given:

Consider the below figure attached with this question.

∠EFH = (5x + 1)°, ∠HFG = 62°, and ∠EFG = (18x + 11)°

To find:

The measure of ∠EFH.

Solution:

From the figure it is clear that ∠EFG is divide in two parts ∠EFH and ∠HFG. So,

$\angle EFG=\angle EFH+\angle HFG$

$18x+11=(5x+1)+(62)$

$18x+11=5x+63$

Isolate variable terms.

$18x-5x=63-11$

$13x=52$

Divide both sides by 13.

$x=\dfrac{52}{13}$

$x=4$

The value of x is 4.

$\angle EFH=(5x+1)^\circ$

$\angle EFH=(5(4)+1)^\circ$

$\angle EFH=(20+1)^\circ$

$\angle EFH=21^\circ$

Therefore, the measure of ∠EFH is 21°.

BRAINLIEST!!! 11. Solve the inequality and graph the solution on a number line.

PilotLPTM [1.2K]

Answer:

y≤-1/3 (fraction)

And on the number line it will start from -1/3 (-0.333) and go less than -1/3 ( to the left, and it will be shaded

Step-by-step explanation:

First we expand the brackets, making it -15y+12≥17

Then we move 12 to the other side, making it negative, -15y≥17-12

Simplify, -15y≥5

Then we divide on both sides to isolate y, flipping the greater than sign to less than because when you divide or multiply by a negative number, the sign flips. y≤5/-15

Then we simplify by dividing the fraction by 5, making it -1/3. y≤-1/3

Kahi can eat 32 pieces of candy in 1 hr her sisters can eat the same amount in 3 hrs how long will it take both them togethr to

pantera1 [17]

So, in order to find the answer, this is what we are going to do.
Let K be the number of candies that Kahi can eat per hour and S be the number of candies that her sisters can eat per hour.
So for the sisters, let us divide 32 by 3 and we get, 10.67. so 10.67/ hour.
Now, consider this expression: (K+S)*h = 32
Plug in the given values.
(32 +10.67)h = 32
42.67h = 32
Divide both sides by 42.67 and we get
h= 1.33. Therefore, it will take 1.33 hour for both of them together to eat 32 candies. Hope this answer helps.
