Answer: simple interest rate is 19%
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the amount invested.
P represents the principal or amount invested.
R represents interest rate
T represents the duration of the investment in years.
From the information given,
P = 90000
I = 400000 - 90000 = $310000
T = 18 years
Therefore,
310000 = (90000 × R × 18)/100
310000 = 16200R
R = 310000/16200
R = 19%
Answer:
Step-by-step explanation:
The path covered by the volleyball will be a downward parabola with the vertex being the highest point of the ball.
A general form of a downward parabola is given as:
Where 
is the vertex of the parabola and 'a' is a constant.
Now, let 'h' be the vertical height and 't' be the time taken.
So, the equation would be of the form:
Now, as per question:
h = 2 seconds, k = 13 feet.
Now, taking a = 1. So, the formula that can be used is:
Answer and Step-by-step explanation:
A) A(t) = 5000(1 + 0.012)t
B) A(t) = 106260
A) 5000 is the initial amount, 1 + 0.012 is the interest rate, and t represents the years.
B) When we plug 21 into the equation, we get 106260.

The estimate that 2.8 million square feet of the building is used for office space is not reasonable
<h3>How to determine the true statement?</h3>
From the plan, the width of the building is:
Width = 230 feet
The building has a circular area, and it has four floors
So, the estimate of the building area is:
Area= 4πR²
So, we have:
Area= 4 * 3.14 * 230²
Evaluate
Area= 664424
The above value cannot be approximated to 2.8 million
Hence, the estimate used for office space is not reasonable
