If C lies between A and B on AB¯¯¯¯¯¯, then AC + CB = AB. Choose the option you can logically conclude about AB¯¯¯¯¯¯. AB is a line segment. Point C is on the line segment AB. The distance between point A and C is five point five and the distance between point C and B is five point two. A. AB = 2(AC) B. AB = 11 C. AB = 10.7 D. none of the above

Answers

C. AB = 10.7

Since we know that AC=5.5 and CB=5.2, we can add them up to get get AB.

5.5+5.2=10.7

redo question 18 above with the same amount of deposit and the same interest rate, but with the interest compounded quarterly. how much money would you have at the end of the four years in this situation?

Answers

There are no given figures. I'll just show what the difference is. Let us assume the following
Principal = 10,000
interest rate = 12%
term = 4 years

Simple Interest = Principal * interest rate * term
S.I = 10,000 * 12% * 4 years
S.I = 4,800

Total value at the end of 4 yrs = 10,000 + 4,800 = 14,800

Compounded Interest. Compounded quarterly.
A = P(1 + r/n)^n*t
A = 10,000 (1 + 12%/4)^4*4
A = 10,000 (1.03)^16
A = 10,000 (1.60)
A = 16,000 value after 4 years.

The solution to the equation 14h = 98 is h = 7.

To solve for h in the equation 14h = 98, we can divide both sides of the equation by 14. This gives us:

h = 98 / 14

h = 7

Therefore, the solution to the equation 14h = 98 is h = 7.

example
if ab=6
and a=3
b=2

a. 6 must be factor of 3 or 2 FALSE
b. 3 must be a factor of 3 OR 2 TRUE
