Applying the Compound Interest Formula

Mathematics
1 answer:
Dmitry_Shevchenko [17]3 years ago
4 0

Answer:

The amount is $8358.7 and the interest is $3858.7.

Step-by-step explanation:

STEP 1: To find amount we use formula:

 

A=P(1+rn)n⋅t

A = total amount  

P = principal or amount of money deposited,

r = annual interest rate  

n = number of times compounded per year

t = time in years

In this example we have

P=$4500 , r=7% , n=2 and t=9 years

After plugging the given information we have

 

 

A=4500(1+0.072)2⋅9A=4500⋅1.03518A=4500⋅1.857489A=8358.7

STEP 2: To find interest we use formula A=P+I, since A=8358.7 and P = 4500 we have:

A wastewater treatment plant receives 20million gallons per day (mgd) of flow. This wastewater has a solid concentration of 384m
xxMikexx [17]

Answer:

64,092.73 pounds

Step-by-step explanation:

1 gallon = 3.78541 liter

1 pound = 453592 mg

In order to obtain the weight of solids that enter the plant each day, simply multiply the wastewater flow by the solids concentration and make the necessary unit adjustments:

W=20,000,000\ gal*384\frac{mg}{L}*\frac{3.78541\ L}{1\ gal}*\frac{1\ lbs}{453592\ mg} \\W=64,092.73\ lbs

64,092.73 pounds of solids enter the plant each day.

The base of a circular fence with radius 10 m is given by x = 10cos(t), y = 10sin(t). the height of the fence at position (x, y)
Karo-lina-s [1.5K]
The average height of the fence is 2 m; its length is 20π m. So, its 2-sided area is
  A = 2*(2 m)*(20π m) = 80π m² ≈ 251 m²

At 1 L/(100 m²), it will take 2.51 L of paint to paint both sides.

Finding the inverse function of f(x) = 5\sqrt{x + 3} - 2, it is best described by graph B.

<h3>How to find the inverse of a function?</h3>

Supposing we have a function y = f(x), to find the inverse, we exchange x and y, and isolate y.

In this problem, the function is:

f(x) = 5\sqrt{x + 3} - 2

y = 5\sqrt{x + 3} - 2

Exchanging x and y:

x = 5\sqrt{y + 3} - 2

Working through the function to isolate y:

5\sqrt{y + 3} = x + 2

\sqrt{y + 3} = \frac{x + 2}{5}

(\sqrt{y + 3})^2 = \left(\frac{x + 2}{5}\right)^2

y + 3 = \frac{(x + 2)^2}{25}

y = \frac{(x + 2)^2}{25} - 3

f^{-1}(x) = \frac{(x + 2)^2}{25} - 3

Which is best represented by graph B.
