You need a $12,000 loan to buy a good used car. Your bank offers a 3-year loan with an APR of 5% and a 5-year loan with an APR of 8%. Find the monthly payment and total interest paid for each loan option. Which would you choose? What is the better deal?
In case of APR 5% total payment made is $12,947.42 and in case of APR 8% total payment made is $14,598.94. Therefore the better deal to choose to pay the less payment is 1st case.
Define APR.APR is the annual interest produced by a sum that is paid to investors or charged to borrowers is referred to as the annual percentage rate (APR). This does not account for compounding and includes any fees or additional expenditures related to the transaction. Consumers can evaluate lenders, credit cards, or investment goods using the APR as a benchmark figure.
Initial payment is $12,000 with 5% APR and 3 year loan
Monthly payment = P[ i(1+i)ⁿ] / [(1+i)ⁿ-1]
= 12,000[0.05(1+0.05)³]/[1+0.05)³-1]
=$359.65
Over 36 payments total payment is $12,947.42
And in case of 8% APR with a 5 year loan
Monthly payment = 12,000[0.08(1+0/08)⁵] / [(1+0.08)⁵-1]
=$243.31
Over 60 payments total payment is $14,598.94
So, the best deal is 5% APR with a 3 year loan.

In an adjacency list representation, corresponding to each vertex v is a linked list such that each node of the linked list contains the vertex u, and there is an edge from v to u.
This is a common way to represent a graph in computer memory, where each vertex is represented by an object that stores its adjacent vertices in a list. This representation is useful when the graph is sparse, meaning it has relatively few edges compared to the number of vertices it has. It is not as efficient for dense graphs, where the number of edges is close to the maximum possible number of edges.

Caroline went to the grocery store and bought bottles of soda and bottles of juice.
Each bottle of soda has 30 grams of sugar and each bottle of juice has 15 grams of sugar. Caroline purchased a total of 6 bottles of juice and soda which collectively contain 150 grams of sugar. Graphically solve a system of equations in order to determine the number of bottles of soda purchased, ∞, and the number of bottles of juice purchased, y.
The solution of the system of equations is the point of intersection (4, 2), as shown in the graph below.
Caroline bought 4 soda bottles.
Caroline bought 2 juice bottles.
How to Solve a System of Equations?In order to determine the solution to this problem, use the information given to create two equations.
Number of soda bottle = x.
Number of juice bottle = y.
First Equation for the total number of bottle that Kelvin bought
x + y = 6 --> eqn. 1
Second Equation 2 for the total sugar in the soda bottles and total sugar in juice bottles that equals 150 grams of sugar.
30x + 15y = 150
Simplify by dividing by 5
6x + 3y = 30 --> eqn. 2
Rewrite eqn. 1:
y = 6 - x
Solve simultaneously for the variables of x and y, by substituting the value of y into equation 2:
6x + 3(6 - x) = 30
6x + 18 - 3x = 30
3x + 18 = 30
3x = 30 - 18
3x = 12
3x/3 = 12/3
x = 4
Caroline bought 4 soda bottles.
Substitute x = 4 into equation 1 to find the value of y:
x + y = 6
4 + y = 6
y = 6 - 4
y = 2
Caroline bought 2 juice bottles.

Work out the surface area of this solid
prism.
10cm
8cm
27cm
6cm
17cm
30cm
The diagram is not drawn to scale.
Answer:
2064 cm²
Step-by-step explanation:
You want the surface area of a prism that is 30 cm between bases that are trapezoids with parallel sides 27 cm and 6 cm that are 8 cm apart, and slant sides that are 10 cm and 17 cm.
Base areaThe area of each trapezoidal base is ...
A = 1/2(b1 +b2)h
There are two identical bases, so their total area is ...
2A = (b1 +b2)h = (27 cm +6 cm)(8 cm) = 264 cm²
Lateral area
The lateral area of the prism is the area of the four rectangular faces. Each is 30 cm wide, and their total length is the perimeter of the base;
P = 27 cm +10 cm +6 cm +17 cm = 60 cm
lateral area = Ph = (60 cm)(30 cm) = 1800 cm²
Total surface area
The total surface area of the prism is the sum of the base area and the lateral area:
total area = base area + lateral area
total area = 264 cm² +1800 cm² = 2064 cm²
The surface area of the solid prism is 2064 cm².

A student receives a subsidized student loan for $10,000 with a 10-year repayment term and interest compounded monthly. Six months after she graduates from college, she will have to begin making payments. Find her monthly payment and total interest paid if the interest rate is 5.5%.
If the interest rate is 5%, the monthly payment and total interest would be $2.439.
Define interest.Interest is the sum of money that must be repaid on a loan or received in exchange for a loan. Principal refers to the borrowed or lent funds. The Amount is the total of the principal plus interest. The term "rate of interest" refers to the rate at which interest is applied to the principal.
Given,
A student receives a subsidized student loan for $10,000 with a 10-year repayment term and interest compounded monthly. Six months after she graduates from college, she will have to begin making payments.
A $10,000 subsidized student loan
Ten-year term of repayment
5.5% interest rate
First, we must determine the loan's future value (FV) over the next six months using the formula below:
FV in 6 months
= Loan Amount× (1 + Interest Rate)⁶ ($10,000×(1 + 0.055) ×6
= $2.7680.
Second, the formula for determining future value is used to determine the monthly payment:
M = FV in 6 months / (((((r)n) - 1) / r).......... (1)
When you enter all the pertinent values into equation (1), you get:
M = $2.7680 / ((((1 + 0.00466666666666667)^144) – 1) / 0.00466666666666667)

The largest possible value of 2 that satisfies the equation is approximately 1.1.
What is Exponential Form Equation?
Since y=bx, y = b x is a one-to-one inverse of the exponential function, x=by x = b y, it too is a function. We simply swap x and y and solve for y to discover the inverse function, as is the case with all inverse functions.
To solve for m in the equation -2 * log(m) - 24 = -20, we can start by converting the equation into exponential form. To do this, we can raise both sides of the equation to the power of e:
[tex]e^(-2 * log(m) - 24) = e^(-20)[/tex]
Then we can simplify:
[tex]m^(-2) = e^(-20)[/tex]
Then we can solve for m:
[tex]m = sqrt[e^20]\\\\= sqrt[20*e^9]\\\\= sqrt[20] * sqrt[e^9]\\\\= 2 * 3^(1/2)= 2 * 1.732\\\\= 3.464[/tex]
So m is approximately equal to 3.464
To find the largest value of 2 that satisfies the equation [tex]log(2^2) - log(2 + 1) = 9[/tex], we can start by expanding the left-hand side of the equation:
[tex]log(2^2) - log(2 + 1) \\\\=log(2^2 / (2 + 1))\\\\ = log(4/3) = 9[/tex]
Then we can rewrite the equation as:
log(4/3) = 9
Then we can solve for 2:
[tex]2 = (4/3)^(1/9)\\\\= (4^(1/9)) / 3^(1/9)\\\\= 1.5874010519681994 / 1.4422495703074083\\\\= 1.1[/tex]

One factor of the function f(x) = x3 − 6x2 + 11x − 6 is (x − 3). the x-intercepts and the y-intercept of the graph of f(x) are
x = 2, x = 3, and x = 4.(0, -6), (2, 0), (3, 0), and (4, 0). RespectivelyWhat are the x-intercepts?Generally, To find the x-intercepts, we set y equal to 0 and solve for x. In this case, the equation we need to solve is:
f(x) = x^3 - 6x^2 + 11x - 6 = 0
To solve this equation, we can use the fact that (x - 3) is a factor of the function. This means that we can write the function as:
f(x) = (x - 3)(x^2 - 3x + 2)
If (x - 3) is a factor, then x - 3 must equal 0. This gives us one x-intercept at x = 3.
To find the other x-intercepts, we can set the quadratic factor (x^2 - 3x + 2) equal to 0 and solve for x. This gives us the following equation:
x^2 - 3x + 2 = 0
We can use the quadratic formula to solve this equation:
x = (3 +/- √(9 - 8)) / 2 = (3 +/- √(1)) / 2 = (3 +/- 1) / 2
This gives us two more x-intercepts at x = 2 and x = 4.
So the x-intercepts of the graph of f(x) are x = 2, x = 3, and x = 4.
To find the y-intercept, we set x equal to 0 and solve for y. In this case, the equation we need to solve is:
f(0) = 0^3 - 6(0)^2 + 11(0) - 6 = -6
This gives us a y-intercept at (0, -6).
So the y-intercept of the graph of f(x) is (0, -6).
All of the intercepts of the graph of f(x) are, therefore (0, -6), (2, 0), (3, 0), and (4, 0).

(4) x (4) = 16
