Haley’s work evaluating (Negative 2) Superscript 8 is shown below.
PSYCHO15rus [73]

Answer:

D

Step-by-step explanation:

<em>The statements are shown below:</em>

<em>A) She used the wrong number as a repeated factor and should have evaluated -2x2x2x2x2x2x2x2. </em>

<em>B) She used the wrong number as a repeated factor and should have evaluated -(8x8). </em>

<em>C) She misinterpreted the exponential form and should have multiplied -2 and 8. </em>

<em>D) She made a sign error when multiplying and should have had 256 as a final answer.</em>

<em />

<u>Solution:</u>

<u />

The problem to simplify is:

(-2)^{8}

Haley's steps are shown below:

(-2)^{8}=(-2)(-2)(-2)(-2)(-2)(-2)(-2)(-2)=-256

Generally,

(a)^b  is actually "a" multiplied "b" times.

So, Haley wrote "-2" eight times multiplied together. That is okay.

Now,

We are dealing with negative numbers.

  • When negative numbers are multiplied "odd" number of times, the answer is negative.
  • When negative numbers are multiplied "even" number of times, the answer is positive.

Haley wrote "-2" eight times, which is EVEN number of times, so the answer would be POSITIVE. But, Haley's answer is negative. Which is wrong. But "256" is right.

Haley's error is:

Find the length of the third side. If necessary, write in simplest radical form.
Arlecino [84]
Answer:

9

Explanation:

9 root 2 = root 81 x root 2 = root 162
Root 162 = 12.7279220614
9^2 + b^2 = 12.7279220614^2
81 + b^2 = 162
b^2 = 81
Root both
B = 9

The drama club sold bags of candy and cookies to raise money for the spring show. Bags of candy cost $8.50, and bags of cookies
Lina20 [59]

The bags of candy that was sold is 6

The bags of cookies that was sold is 10.

<h3>What are the linear equations that represent the question?</h3>

$8.50c + $4.50o = 79 equation 1

o - c = 6

o = 6 + c  equation 2

Where:

  • o = bags of cookies sold
  • c = bags of candies sold

<h3>How many  bags of candy and cookies were sold?</h3>

Substitute for o in equation 1 using equation 2

$8.50c + $4.50(6 + c) = 79

$8.50c + 27 + 4.50c = 79

$8.50c + 4.50c = 79 - 27

$13c = 52

c = 52 / 13

c = 4

Substitute for c in equation 2

0 = 6 + 4 = 10
