50pts!!! I need proper help and an easy to understand explanation.
1 answer:
So since we know that the post is 40 yards away, plug in 40 into the x variable of the equation to solve. If y is greater than 10 when x = 40, then it made it over. If y is less than 10 when x = 40, then it does not make it over.
Firstly, solve the exponent:
Next, solve the multiplications:
Lastly, solve the addition and your answer will be:
Since the football was 16 ft high, as opposed to the goal post's 10 ft, when it was at the goal post, it had successfully gone over the post. And since 16 ft is 6 ft higher than 10 ft, the football was 6 ft higher than the goal post when it went over.

Step-by-step explanation:
<u>Compound Interest Formula</u>
where:
- A = final amount
- P = principal amount
- r = interest rate (in decimal form)
- n = number of times interest applied per time period
- t = number of time periods elapsed
<u>Part (a): semiannually</u>
Given:
- P = $15,000
- r = 5.5% = 0.055
- n = 2
- t = 6 years
Substitute the given values into the formula and solve for A:
<u>Part (b): quarterly</u>
Given:
- P = $15,000
- r = 5.5% = 0.055
- n = 4
- t = 6 years
Substitute the given values into the formula and solve for A:
<u>Part (c): monthly</u>
Given:
- P = $15,000
- r = 5.5% = 0.055
- n = 12
- t = 6 years
Substitute the given values into the formula and solve for A:
<u>Continuous Compounding Formula</u>
where:
- A = Final amount
- P = Principal amount
- e = Euler's number (constant)
- r = annual interest rate (in decimal form)
- t = time (in years)
<u>Part (d): continuous</u>
Given:
- P = $15,000
- r = 5.5% = 0.055
- t = 6 years
Substitute the given values into the formula and solve for A:
