Allushta [10]3 years ago
8 0

Answer:

7.D

8.A

Step-by-step explanation:

7.

r=√((0-6)²+(0+8)²)=√(36+64)=√100=10

eq. of circle is (x-6)²+(y+8)²=10²

(x-6)²+(y+8)²=100

8.

CM=1/2CD=1/2×60=30

OM=18

OC=√(30²+18²)=√(900+324)=√(1224)=√(4×306)=√(4×9×34)=2×3√34=6√34

radius r=OC=6√34

OF=r=6√34

ON=15

FN=√((6√34)²-15²)=√(1224-225)=√999=√(9×111)=3√111

Find the value of X.<br><br><br>3(4x + 8) = - 35+23​
damaskus [11]

Answer:

x = -3

Step-by-step explanation:

3(4x + 8) = - 35+23​

Combine like terms

3(4x + 8) =-12

Divide by 3

3/3(4x + 8) = -12/3

4x+8 = -4

Subtract 8 from each side

4x+8-8 = -4-8

4x = -12

Divide by 4

4x/4 = -12/4

x = -3

A weed called the raindrop vine is known for growing at a very fast rate.
Vinvika [58]

First, we need to convert 0.75 feet to inches.

0.75 feet = 9 inches

Now, we need to divide 9 by how many hours are in a day, which is 24.

9/24 = 0.375

The raindrop vine can grow up to 0.375 inches per hour.

you deposit 10000 into a bank account. the account pays 4 annual interest compounded quarterly. find the balance after 5 years.
Ann [662]
<h3>Answer: 12,201.90 dollars</h3>

You may need to delete the comma if you are entering this result into a computer system.

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

Work Shown:

P = 10,000 = deposit

r = 0.04 = decimal form of 4% interest rate

n = 4 = we're compounding 4 times a year

t = 5 years

-------------

A = P*(1+r/n)^(n*t) .... compound interest formula

A = 10,000*(1+0.04/4)^(4*5)

A = 12,201.9003994797

A = 12,201.90

After 5 years, there is $12,201.90 in the account.

This is assuming you do not deposit any more money, and it also assumes that you don't take any money out during the 5 year timespan either.
