The length of a rectangle is 8 inches longer than half of its width.The area of the rectangle is 18 square inches.How many inches wide is the rectangle
Answer:
The correct answer is 2 inches.
Step-by-step explanation:
Let l inches and w inches be the length and width of a rectangle respectively.
According to the given problem, l - 8 = [tex]\frac{w}{2}[/tex].
Area of the rectangle is given to be, according to the question, 18 square inches.
Thus l × w = 18
⇒ l × (2l - 16) = 18
⇒ 2 [tex]l^{2}[/tex] - 16l - 18 = 0
⇒ [tex]l^{2}[/tex] - 8l - 9 = 0
⇒ ( l - 9) ( l + 1) = 0
The possible values of l are 9 and -1. As the length cannot be equal to -1, thus the value of the length is 9 inches.
Width of the rectangle is 2 inches.

Your college fund has $65,000. It is currently in an account which pays 2.3% compounded monthly. How much money will you have in 15 years
Answer:
$91,749.04
Step-by-step explanation:
Lets use the compound interest formula provided to solve this:
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
P = initial balance
r = interest rate (decimal)
n = number of times compounded annually
t = time
First, change 2.3% into a decimal:
2.3% -> [tex]\frac{2.3}{100}[/tex] -> 0.023
Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:
[tex]A=65,000(1+\frac{0.023}{12})^{12(15)}[/tex]
[tex]A=91,749.04[/tex]
You will have $91,749.04 in 15 years.
Joe wants to rent an apartment with an initial monthly rent of $1,400. He has been told that the landlord raises the rent 1.25% each year. Using an exponential function ( or a method of your own) to model this situation, calculate the rent that Joe will have to pay for the 4th year of living in the apartment.
Answer: his pay for the 4th year is $1453.16
Step-by-step explanation:
The landlord raises the rent 1.25% each year. It means that the rent is increasing in geometric progression.
The formula for determining the nth term of a geometric progression is expressed as
Tn = ar^(n - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
From the information given,
a = $1,400
r = 1 + 1.25/100 = 1.0125
n = 4 years
The 4th term(year), T4 is
T4 = 1400 × 1.0125^(4 - 1)
T4 = 1400 × 1.0125^3
T4 = $1453.16
Using an exponential function, the rent Joe will have to pay for the fourth year, with a 1.25% annual increase, is approximately $1,453.38.
To calculate the rent Joe will have to pay for the fourth year of living in the apartment with an annual rent increase of 1.25%, we will use an exponential function. The general formula for compounded growth is given by:
Future Value = Present Value ×(1 + rate)number of periods
In Joe's case, the Present Value is the initial monthly rent of $1,400, the rate is 1.25% or 0.0125 when expressed as a decimal, and the number of periods is 3 years since we are calculating the rent at the start of the fourth year. Plugging these values into the formula:
Rent for the fourth year = $1,400 × (1 + 0.0125)3
Let's calculate that:
Rent for the fourth year = $1,400 × (1.0125)3
Rent for the fourth year approximately = $1,400 × 1.038128
$1,453.38
Hence, Joe will have to pay about $1,453.38 for the fourth year of rent.
