Answer:
rectangle: 30 in^2
triangle: 12 in^2
composite: 42 in^2
Step-by-step explanation:
area of a rectangle: length times width
area of a triangle: 
composite area: break the area up by shapes you can find the area of, then add it back together
Answer:A. 3x^2-2x-1+9x+2x^2-3=5x^2+7x-4
B. 5x^3+4x^2-x-3-5x^2-7x+4=5x^3-x^2-8x+1
C. Polynomials are closed under addition and subtraction...
Step-by-step explanation:
$12.80 is your answer.. see all you needed to do was divide $2.40 by three.. as that is one oz you would only then multiply by twelve for your answer.
Given:
• Amount to save, A = $28,000
,
• Time, t = 6 years
,
• Interest rate, r = 5.3% ==> 0.053
,
• Number of times compounded = quarterly = 4 times
Let's find the amount that must be deposited into the account quarterly.
Apply the formula:

Where:
FV is the future value = $28,000
r = 0.053
n = 4
t = 6 years
Thus, we have:

Let's solve for P.
We have:

Solving further:

Divide both sides by 28.0384237:

Therefore, the amount that must be deposited quarterly into the account is $998.60
