Damien deposited $250 in an account that earned 3.75% interest compounded annually. He did not make additional deposits or withdrawals. What will be the balance in this account at the end of 4 years? $127.26 $287.50 $289.66 $370.50
Answers
Answer:
$289.66
Step-by-step explanation:
A=P(1+r)^t
P=250
r= .0375
t= 4
A=250(1+.0375)^4
A= 289.66
$ 289.66 will be the balance at the end of the 4 years.
What is compound interest?One of the most important ideas in finance is compound interest, which means that the interest you earn each year is added to your principal and grows at a growing rate. It serves as the foundation for everything from a personal savings strategy to long-term stock market development. It also takes into consideration the effects of inflation and the relevance of debt repayment.
Given, Damien deposited $250 in an account that earned 3.75% interest compounded yearly. Hence,
principal amount = 250
rate = 3.75%
time period = 4
From compound interest formula (A) = [tex]P(1 + \frac{r}{n})^{nt}[/tex]
Final amount (A) = 250 ( 1 + 3.75/ 1)^4 = 289.66
Therefore Damien will have 283.66$ at the end of the four years.

Answer:
15π cubic units
Step-by-step explanation:
the formula for the volume of a cone is:
V = (base area x height) / 3
In this case we have
(5π x 9)/3 = 15π cubic units
Answer:
235.5 Cubic Units
Step-by-step explanation:
V=1/3B*H
=1/3(π5^2)9

=3(3.14*25)
=75*3.14=235.5 Cubic Units
The retangular prism shows is made from cubs.Each cube is 1 cubic unit. What is the volume in cubic units
Answers
Answer:
72 square units
Step-by-step explanation:
To get these, we will use the attached diagram as a case study
Since each cube is 1cubic unit, hence the length of the side of a cube is 1unit
From the diagram
Length = 6units
Width = 3 units
Height = 4units
Volume of the prism = Length * Width * Height
Volume of the prism = 6 * 3 * 4
Volume of the prism = 18 * 4
Volume of the prism = 72 sq.units
Hence the volume of the prism is 72 square units

Answers
Answer:
30.67
Step-by-step explanation:
Given the following
Opposite side = x
Adjacent = 17
Angle = 61degrees
Using the SOH CAH TOA identity
tan theta = opp/adj
tan 61 = x/17
x = 17tan61
x = 17(1.8040)
x = 30.67
Hence the value of x is 30.67
A small car has a tire with a 13-inch diameter. A truck has a tire with a 29-inch diameter. How much farther than the car does the truck have to drive for its tire to complete one revolution?
Answers
Answer:
50.27in
Step-by-step explanation:
Given data
Diameter of small tire= 13in
Radius= 13/2= 6.5in
Circumference= 2πr
C= 2*3.142*6.5
C= 40.85 in
Diameter of Big tire= 29in
Radius= 29/2= 14.5in
Circumference= 2πr
C= 2*3.142*14.5
C= 91.118in
Hence the difference in distance between the two tires after on revolution is
=91.118-40.85
=50.27in
If the student is a domain/inout and the hair color is the range/output how is these two set of relation not a function?
Answers
Answer:
A function is a relation that maps inputs from a set called the domain, into outputs from a set called the range.
Such that each input can be mapped into only one output.
So for example, if we have a relation that maps the input 2 into two different values:
f(2) = 4
f(2) = 8
Then this is not a function.
In the case of the problem, we have a student as the input, and the hair color as the output.
So we will have something like:
f(student) = blond
And if this student decides to change his/her hair color to red?
Then the function becomes:
f(student) = red
So for the same input, we had two different outputs, which means that this is not a function.
We also could have the case where a given student has two colors (Californian for example)
Where again, we would see two different outputs for one single input.
