Answer:  8^4 \times 3^2

On a keyboard, you can type 8^4*3^2 to indicate the same thing.

===========================================================

Explanation:

There are four copies of 8 being multiplied. Writing 8^4 is a shorthand way of saying 8 \times 8 \times 8 \times 8. The exponent tells us how many copies of the base to multiply out.

Similarly, we have two copies of 3 which means 3 \times 3 = 3^2

Step-by-step explanation:

8 ^{4}  \times 3 {}^{2}

Count how many of the same number, since you have four 8's the exponent will be

8 {}^{4}

same applies for 3

ANSWER

D. 13

EXPLANATION

We have

f(x) =  \frac{2x + 1}{x - 4}

To find

{f}^{ - 1} (3)

means we want to find an x-value whose image is 3.

\frac{2x + 1}{x - 4}  = 3

We cross multiply,

2x + 1 = 3(x - 4)

Expand:

2x + 1 = 3x - 12

Combine like terms,

3x - 2x = 12 + 1

x = 13

\therefore{f}^{ - 1} (3)= 13

2. Sandi can run for one hour at a constant speed of 348 cm per second. Marci can run for one
Zanzabum

Answer:

Marci is the faster runner.

Step-by-step explanation:

Sandi can run 348 cm in a second. Let's find out how many cm she can run in a minute: in a minute there are 60 seconds. So lets multiply 348cm times 60, this gives you 20,880. That is how much she travels in a minute, now let's find out how much she runs in an hour: if she runs 20,880 cm in an minute and there are 60 minutes in an hour, then all you have to do is multiply 20,880 times 60, this gives you 1,252,800. That is how many cm she runs in an hour. Now let's change from cm to miles. There are 160,934 cm in a mile. If we divide 1,252,800 by 160,934 this will give you

Zachary says that the equation 0 =-1/2 (x – 4)(x –
melomori [17]
<u><em>Answer:</em></u>
c = 4

<u><em>Explanation:</em></u>
The number of solutions for any equation is equal to the degree of the equation.

The given equation is a second degree equation which means that it has two solutions.

The only possible way for it to have one unique real solution is that the two <u>solutions are equal</u>

<u>This means that:</u>
x - 4 = x - c
<u>Now, we solve for c:</u>
x - 4 - x = x - c - x
-4 = -c
c = 4

Hope this helps :)

Evaluate the following using<br> powers of ten rules.<br> 104)1.042
Alinara [238K]

Answer:

0.0001042

Step-by-step explanation:

Power of tens rule states that if the denominator of a fraction has the positive power of 10, decimal in the numerator will be shifted to the left by the same number of places as exponent.

10⁴) 1.042 = \frac{1.042}{10^4}

In the denominator of the given fraction, exponent of 10 = +4

So the decimal in numerator will be shifted left by 4 places.

\frac{1.042}{10^4}=0.0001042

Therefore, answer is 0.0001042
