Ok, 8^(-5) divided by 8^(-3) would be 8^(-5-(-3)), because when you divide numbers with the same base, you subtract the exponents. That would be 8^(-2), which I suppose is A

Ghella [55]

Answer:

x = 4.

Step-by-step explanation:

We see that it passes through the x axis at the point (4, 0) so x = 4 is a solution.

Check by solving the equation

x^2 - 4x + 13 = 13

Subtract 13 from both sides:

x^2 - 4x = 0

x(x - 4) = 0

x = 0 or x - 4 = 0, so:

x = 0 or 4.

Bond [772]

Answer:

Coach's friend jog 8.6 miles.

Step-by-step explanation:

Given:

A coach jogs 1.8 miles on Monday, 1.3 miles on Tuesday, and 1.2 miles on Wednesday.

If the coach's friend jogs twice as far as the coach.

Now, to find the miles the coach's friend jog.

Coach jogs on Monday = 1.8 miles.

Coach jogs on Tuesday = 1.3 miles.

Coach jogs on Wednesday = 1.2 miles.

Total miles coach jog = $1.8+1.3+1.2=4.3\ miles.$

As, coach's friend jogs twice as coach.

So, to get the miles coach's friend jogs multiply total miles coach jog by 2 we get:

$Total\ miles\ coach\ jog\times 2$

$4.3\times 2\\\\=8.6\ miles.$

Therefore, coach's friend jog 8.6 miles.
