Compundinterest
F=P(1+(r/n))^(nt)
F=future value
P=present value
r=rate in decimal form
n=number of times per yera it is compunded
t=time in years
P=20000
r=0.03
12 months per year so n=12
t=15
F=20000(1+(0.03/12)^(12*15)
F=20000(1.0025)^(180)
F=20000(1.56743)
F=31348.634
round
$31348.63
B is answer
Break it down into shapes you know. There's a triangle and a rectangle. The area of a rectangle is l*w and in this case it's 5*6 or 30 units². The area of a triangle is 1/2b*h and in this case that is 1/2 * 6 * 3 or 9 units². Add the areas together to find the total area, which is 39 units².
Step-by-step explanation:
a)
Dividing both sides by sin^2x, we get
The 2nd term on the LHS is simply cot^2x and the RHS is simply csc^2x
b)
You can also graph it to arrive at the solution.
Answer:
1
Step-by-step explanation:
12 divided by 4 = 3
3 divided by 3 = 1
1/4
Answer:
Two.
Step-by-step explanation:
In algebra, a term is either a single number or variable, or numbers and variables multiplied together. In any equation, all of the numbers there that aren't divided by a mathematical operation (times or divide symbols) are terms.
3x2 isn't a term, it's an expression - but 5x and 9 are, so therefore there are 2 terms.
