(x + 4) (x - 3)
a = 4
b = -3
a^2 + b^2 = ...
= 4^2 + (-3)^2
= 16 + 9
= 25
Answer:
B=208.72
Step-by-step explanation:
June 22
July: 22+ 22x (1+10%) = 46.2
Auq: 46.2+ 22 (1+10%) x (1+10%)= 72.82
Sep: 72. 82+ 22 (1+10%)³= 102.102
Oct: 102.102 + 22 x(1+10%)⁴= 134.3122
Nov: 134.3122 + 22×(1+10%)⁵= 169.74342
Dec:169.74342 +22(1×10%)⁶ =208.717762
=208.72
The calulation of Compound interest )
Answer:
Surface area = 4 π r2 square units
Step-by-step explanation:
Answer:
3.33% per hour
Step-by-step explanation:
Use the A=Pe^rt equation. A is the end amount, so it's 1892. P is the original amount, 1700. E is a constant, around 2.72. R is the growth constant. T is the time that passed, 3 hours. You can substitute the givens into the equation and get 1892=1700e^(3r). Divide by 1700 to isolate the e. This leaves you with 1892/1700=e^(3r). Do the natural log of each side cancel the e and bring the exponent down. This leaves you with ln(1892/1700)=3r. Divide by 3 to isolate r. ln(1892/1700) is .1. .1/3 is .03333. Multiply by 100 to get a percent. 3.33 percent is your final answer.
