Let's solve your equation step-by-step.
−7x=−2x2+15
Step 1: Subtract -2x^2+15 from both sides.
−7x−(−2x2+15)=−2x2+15−(−2x2+15)
2x2−7x−15=0
Step 2: Factor left side of equation.
(2x+3)(x−5)=0
Step 3: Set factors equal to 0.
2x+3=0 or x−5=0
x= or x=5
Answer:
x= or x=5

Answer:
option (c) $18,032
Step-by-step explanation:
Data provided in the question;
Amount deposited at the end of each day = $1
Interest paid = 8% compounded daily = 0.08
Daily interest rate = = 0.000219
Duration = 20 years = 20 × 365 days = 7300 days
Now,
the Future value is given as:
Future value = Part payment ×
here, r is the interest rate
n is the duration
thus,
Future value = $1 ×
or
Future value = $18033.56 ≈ $18,032
Hence, the correct answer is option (c) $18,032
