Answer:

a^7/8^2

Step-by-step explanation:

Here, we want to write the expression using only positive exponents

An important rule for indices to use here is that;

a^-b = 1/a^b

thus;

8^-2 = 1/8^2

So we have;

1/8^2 * a^7

= a^7/8^2

Find the distance between the two points in simplest radical form.<br> (-9,5) and (0,0)

7nadin3 [17]

Answer:

$\sqrt{106}$ units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 9, 5)

d = $\sqrt{(-9-0)^2+(5-0)^2}$

= $\sqrt{(-9)^2+5^2}$

= $\sqrt{81+25}$

= $\sqrt{106}$

Nathan usually drinks 31 ounces of water per day. He read that he should drink 59 ounces of water per day. If he starts drinking

Pie

You have to know the difference in change, so you do 59-31 and you get 28, then since you want to know the change in percent you divide the difference, which is 28 and divide that by 31, which is the original amount consumed, and you get 28/31, and you get .90 which is 90%
