<u>Part 1: Finding radius</u>

The radius of a circle is defined as the distance from the center to a point on the circle's circumference.

Using the distance formula,

r=\sqrt{(-7-8)^{2}+(-1-7)^{2}}=\boxed{17}

<u>Part 2: Finding the point with x-coordinate -15</u>

Let the y coordinate of the point be y. Then, we have the point (-15, y). Substituting into the distance formula,

\sqrt{(-15-(-7))^{2}+(-1-y)^{2}}=17\\\\64+(-1-y)^{2}=289\\\\(-1-y)^{2}=225\\\\-1-y =\om 15\\\\y=\boxed{-16, 14}

Leona [35]

Answer:

First, you multiply 0.07 by 0.15

60 + (0.07) * (0.15)

60 + 0.0105

= 60.0105

Hal is asked to write an exponential function to represent the value of a $10,000 investment decreasing at 2% annually. What
jek_recluse [69]

Answer:

0.98

Step-by-step explanation:

The investment starts at $10,000.

$10,000 is 100% of the investment.

In the first year, it loses 2% of its value. That means that after 1 year, the value of 100% of $10,000 is decreased by 2% of $10,000.

100% - 2% = 98%

After the first year, the investment is worth 98% of the original value.

98% as a decimal is 0.98

Answer: 0.98
