Answer:
A+ B is the radius of the circle
When we draw line AE it is also a radius of the circle
Line EC^2 = AE^2 -AC^2
Line EC^2 = 8^2 -5^2
Line EC^2 = 64 -25
Line EC^2 = 39
EC = square root of 39 = 6.2449979984
EC = 6.245 rounded.

Answer:
1/2x + 2 because rise over run and y intercept and yea
Step-by-step explanation:
Answer:
y=-x+7
Step-by-step explanation:
every year she goes down how many times she is younger than him by 1 so -x is actually -1x, and it starts at 7 years so we put that as our y intercept
Answer:
6.532 x 10^-9
Step-by-step:
1. 0.000000006532
2. move the decimal to where the first number is greater than or equal to 1 and less than 10. In this case we move the decimal to the right 9 times. You will get 6.532
3. We moved the decimal to the right meaning the power to 10 would be a negative number. The number is how many times we moved the decimal by 1 spot, in this problem we moved it 9 times. 6.532 x 10^-9 is what you should get for scientific notation
