(a) Loan you can afford is $143097.67. (b) Total money will you pay the loan company is $378000. (c) Interest amount is $234902.33.
What is Loan interest ?Loan interest is the additional cost that a borrower must pay on top of the principal amount of a loan. Interest is typically expressed as a percentage of the principal and is charged over a specific period of time. The rate of interest charged on a loan is determined by a variety of factors, including the borrower's creditworthiness and the type of loan. The purpose of interest is to compensate the lender for the risk and cost of providing the loan.
Given data:
Principal = $1050 per month
Time = 30 year
= 30 × 12
= 360 months
Interest rate = 8%
= 0.08/12
= 0.006667 monthly
(a) We get here first maximum amount of loan by present value of annuity as
Present value of annuity = principal × [tex]\frac{1-(1+rate)^{-t} }{rate}[/tex] .........(1)
Put here value we get
value of annuity = 1050 × [tex]\frac{1-(1+0.006667)^{-360} }{0.006667}[/tex]
value of annuity = $143097.67
(b) Total amount = principal × time period
= $1050 × 360
= $378000
(c) Total amount of interest paid will be
interest amount = total amount paid - loan amount
interest amount = $378000 - $143097.67
interest amount = $234902.33

The expression that is a factor of the polynomial x³ + 2x² - 9x - 18 is (x + 2).
How to find the factors of a polynomial?Factoring of a polynomial is the method of breaking the polynomial into a product of its factors.
For example x² - 4 can be broken as (x - 2) and (x + 2).
Therefore, the expression that factor the polynomial x³ + 2x² - 9x - 18 is as follows:
Therefore,
x³ + 2x² - 9x - 18 = (x - 3)(x² + 5x + 6)
Let's break (x² + 5x + 6) down
x² + 5x + 6
x² + 2x + 3x + 6
x(x + 2) + 3(x + 2)
(x + 3)(x + 2)
Therefore, the factors are (x + 3)(x + 2) and (x - 3)

John drew a triangle with side lengths of 5, 12 and 13. His friend, Bryan, looked at it and asked John if it is a right triangle. John’s response was yes. Explain or show how John can prove to Bryan that the triangle is a right triangle
It's a right angle as 13² is the addition of 5² and 12².
How to prove the right angle?A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly known as a rectangled triangle, is a triangle with one right angle, i.e. two perpendicular sides. Trigonometry is founded on the relationship between the sides and other angles of a right triangle.
In this case, the values given are 5, 12 and 13. This will be illustrated thus:
5² + 12² = 13²
25 + 144 = 169
169 = 169
This was done based on Pythagoras theorem.
Therefore, it's a right angle.

What is factorization and compound interest?
Factorization is the reduction of an algebraic expression into two or more algebraic expressions of smaller degree
If the interest on a certain principal at a certain rate over a certain period of time increases exponentially rather than linearly, the interest earned is called compound interest.
1) a) f(x) = x³+7 x²-36
f(2) = 2³+7(2)²-36
f(2) = 36 - 36 = 0
b) Since f(2) = 0, (x - 2) is a factor of f(x)
f(x) = x²(x - 2) + 9x(x - 2) + 18(x - 2)
f(x) = (x - 2)(x² + 9x + 18)
f(x) = (x - 2)(x² + 6x + 3x + 18)
f(x) = (x - 2){x(x + 6) + 3(x + 6)}
f(x) = (x - 2)(x + 6)(x + 3)
c) Let the principal be $p
Rate = 3%
Time = 4 years
[tex]560000 = p(1 + \frac{3}{200})^{4 \times 2}\\\\560000 = p(\frac{203}{200})^8\\\\\\p = 560000 \times (\frac{200}{203})^8\\\\p = 497118.23[/tex]

Find the angle between 0 and 2π in radians that is coterminal with the angle -25π/6
Hi,
I hope you and your family are doing well!
An angle is coterminal with another angle if it has the same terminal side as the other angle, but may have a different degree measure. In other words, coterminal angles are angles that are measured around the same point on the unit circle, but may start at different points.
To find the angle between 0 and 2π in radians that is coterminal with the angle -25π/6, we can add or subtract multiples of 2π to -25π/6 until we get an angle between 0 and 2π.
For example, adding 2π to -25π/6 gives us:
-25π/6 + 2π = -π/6 + 2π = 7π/6
This angle is between 0 and 2π, so it is coterminal with -25π/6.
Alternatively, subtracting 4π from -25π/6 gives us:
-25π/6 - 4π = -29π/6 = -π/2
This angle is also between 0 and 2π, so it is coterminal with -25π/6.
Therefore, the angle between 0 and 2π in radians that is coterminal with -25π/6 is either 7π/6 or -π/2.

The value equivalent to [tex](64)^{1/4}[/tex] is [tex]2\sqrt[4]{4}[/tex].
What is meant by an expression?An expression or mathematical expression is a finite arrangement of symbols that are well-formed in line with context-dependent criteria. To help define the logical grammar and order of operations, mathematical symbols can be used to represent variables, operations, functions, brackets, punctuation, and grouping.
A formula and an expression are often distinguished by authors, with the former designating a mathematical entity and the latter a statement about such a thing.
But in contemporary mathematics, and particularly in computer algebra, formulas are seen as expressions that can be evaluated as true or false, depending on the values given to the variables present in the expressions.
Given expression is [tex](64)^{1/4}[/tex]
The number 64 can be written as 2 × 2 × 2 × 2 × 2× 2 =2⁶
So, the above given expression becomes,
[tex](64)^{1/4}[/tex]=[tex](2^{6}) ^{1/4}[/tex]
2⁶=2⁴.2²
So,
[tex](2^{6}) ^{1/4}[/tex]=[tex](2^{4} 2^{2})^{1/4}[/tex]
By simplifying we get,
[tex](64)^{1/4}[/tex]=[tex]2\sqrt[4]{4}[/tex]

Using trigonometric relations we will see that:

b = 5
The correct option is the one you marked.
How to get the values of a and b?For a right triangle with a known hypotenuse H and a known angle x, we can use the trigonometric relations:
cos(x)= (adjacent cathetus)/h
sin(x) = (opposite cathetus)/h
Here the hypotenuse measures 10 units, and the known angle is x = 30°.
The adjacent cathetus to that angle is a, so we can write:
cos(30°) = a/10
a = cos(30°)*10 = 10*√3/2 = 5*√3
And b is the opposite cathetus:
sin(30°) = b/10
b = 10*sin(30°) = 5

Step-by-step explanation:
this is a college question ?
oh, my dear ...
we start at -426 ft.
swimming upwards reduces depth by adding hight.
so,
-426 + 212 = -214 ft
basically the same method is used as if we would subtract 212 from 426.
so, the diver is currently at -214 ft (214 ft below the surface).

a. For what number of songs will both companies charge the same amount? Justify your answer using mathematics.
_________ Songs
You anticipate that you will download 150 songs. Which company should you choose if you want to spend the least amount of money? Justify your answer using mathematics.
________ (Type Company A or Company B)
a. Using linear equations in one variable we get the number of songs at which both companies would charge the same amount is 100 songs.
b. Company B would be a better choice as the total charges for 150 songs would be $127.5.
Explain linear equations in one variable.
A straight line with only one variable is a linear equation. the single variable's power is 1. Simple algebraic methods are used to solve these equations, which have the form ax+b=0.
a) Assume the number of songs downloaded is 'x'.
Now according to the question,
Total charges by company A is 15+0.75x
Total charges by company B is 0.90x
For equal charges, both must be equal,
Hence equating the 2 expressions we get,
15+0.75x=0.90x
15=0.15x
x=100
Hence total number of songs to reach the charge of the same amount is 100.
b)Let us take 150 songs from company A, we get the total charge to be
15+0.75*150=$127.5
Taking for company B, we get
0.90*150=$135.
We see that for 150 songs, the charges of company A is less compared to company B. Therefore I would choose company B over company A.

The function f(x)=∣x−3∣ can be used to determine how far a number x is away from the number 3 on the number line. Find and interpret the given function values and determine an appropriate domain for the function.
Answer:
The function f(x) = |x - 3| can be used to determine how far a number x is away from the number 3 on the number line. To find the function value for a given x, we first need to subtract 3 from x and then take the absolute value of the result. For example, if x = 5, then the function value would be f(5) = |5 - 3| = |2| = 2.
The domain of the function is the set of all possible values of x that we can plug into the function to get a real number result. In this case, the function will work for any real number value of x, so the domain of the function is the set of all real numbers, which can be written as:
Domain: (-∞, ∞)
In other words, the function f(x) = |x - 3| can be used to determine how far any real number x is away from the number 3 on the number line.
