Answer:
f(3) =-12
f(-1) =-12
Step-by-step explanation:
HELLO THERE
f(3)=-2(3)^2+8(3)
f(3)=-36+24
f(3)=-12
----------------------------
f(-1) =2(-1) ^2+8(-1)
f(-1) =-4-8
f(-1) =-12
//Both equal -12//
HAVE A GREAT DAY
Use the Pythagorean Theorem
6 feet and 14 feet are the "legs" and the ladder length is the hypotenuse.
hypotenuse^2 = 6^2 + 14^2
hypotenuse^2 = 36 + 196
hypotenuse^2 = 232

ladder length = 15 feet

The future value of the investment if the interest is compounded monthly is $89,354.89.
<h3>What is the future value of the investment?</h3>
Given that;
- Principal P = $20,000
- Annual interest rate r = 5% = 5/100 = 0.05
- Time t = 30 years
- Compound monthly = 12
- Future value = A = ?
Using the compound interest formula;
A = P( 1 + r/n )^(nt)
We plug in our values.
A = 20000( 1 + 0.05/12 )^(12 × 30)
A = 20000( 1 + 0.0041666666666667)^(360)
A = 20000( 1.0041666666666667)^(360)
A = 20000( 4.46774965 )
A = 89354.89
Therefore, the future value of the investment if the interest is compounded monthly is $89,354.89.
