Nick’s parents purchased their first home in the 1980’s with a 30-year mortgage at 19.5%.
Answers
$ 2037.40
Interesting that there was no down payment..........The staggering monthly payment above would be enough to pay off the total mortgage in just over 5 years. Nick's parents would be much better off to save their money for a few years.
Final answer:
Using the formula for a fixed-rate mortgage payment, the monthly mortgage payment for Nick's parents, who bought a home for $125,000 with a 30-year mortgage at 19.5%, is calculated to be $2,037.40, making the answer A. $2,037.40.
Explanation:
To calculate the monthly mortgage payment for Nick's parents, who purchased their first home with a 30-year mortgage at 19.5% interest, we need to use the formula for a fixed-rate mortgage payment. The formula is:
M = P[r(1+r)ⁿ]/[(1+r)ⁿ⁻¹]
Where:
M is the total monthly mortgage payment.P is the principal loan amount.r is the monthly interest rate (annual rate divided by 12 months).n is the number of payments (loan term in years multiplied by 12 months).For this calculation:
P = $125,000r = 19.5% annual interest rate, which is 0.195/12 per month.n = 30 years x 12 months = 360 payments.We insert these numbers into our formula:
M = $125,000[0.195/12(1+0.195/12)³⁶⁰]/[(1+0.195/12)³⁶⁰⁻¹]
After calculating, we find that the monthly mortgage payment (rounded to two decimal places) would be $2,037.40.
Therefore, the answer is A. $2,037.40.

Answers
∵ Δ KJL is a right triangle at ∠J
∴ KL is the hypotenuse = 8√2
∵ ∠ JKL = 30°
∴ The side which faces the angle 30° will be the half of the hypotenuse because sin 30° = JL/KL = 0.5
∴ JL = 0.5 KL = 0.5 * 8√2 = 4√2
Δ JML is a right triangle at ∠M
∴ JL is the hypotenuse = 4√2 ⇒⇒⇒ (proved)
∵ ∠LJM = 45° , ML = x
∴ sin 45° = x/JL
∴ x = JL sin 45° = 4√2 * (1/√2) = 4

Explanation:
The given is:
(1/36)^n = 216
Take log base 6 both sides:
log base 6 of (1/36)^n = log base 6 of (216)
log base 6 of (1/6)^2n = log base 6 of (1/6)^-3
2n * log base of (1/6) = -3 * log base 6 of (1/6)
This means that:
2n = -3
n = -3/2
Hope this helps :)
(1/36) ^ n = 216
We use log function:
log ((1/36) ^ n) = log (216)
For log properties we have:
nlog ((1/36)) = log (216)
n = log (216) / log ((1/36))
n = -1.5

Notice that in the denominator all the numbers are divisible by two, so 2 is part of our common factor; also, all the terms have the variable [tex]x[/tex], and the least exponent of that variable is 1, so [tex]x[/tex] will be the other part of our common factor. Lets put the two parts of our common factor together to get [tex]2x[/tex].
Now that we have our common factor, we can rewrite our numerator as follows:
[tex] \frac{2x(x^{5}-6x+2(2y)}{2x} [/tex]
We are luckily, we have [tex]2x[/tex] in both numerator and denominator, so we can cancel those out:
[tex]x^{5}-6x+2(2y)[/tex]
[tex]x^5-6x+4y[/tex]
We can conclude that the simplified version of our rational function is [tex]x^{5}-6x+4y[/tex].

ASAP What is the lateral area of this regular octagonal pyramid?? Explain your answer if you can plz thanks
Answers
The lateral area is the area of all of the lateral faces of the pyramid. There are 8 triangles making up the lateral faces. Each has a base of 6.6. The formula for the area of a triangle is
A=1/2bh,
so we still need the height of the triangle.
The height of each lateral triangle is the slant height of the pyramid. The slant height of the pyramid forms a right triangle with the height of the pyramid and the "radius" as it were of the pyramid. Thus we use the Pythagorean theorem:
8²+8²=h²
64+64=h²
128=h²
√128=√(h²)
8√2 = h
Substituting this into our area formula we have:
A=1/2(6.6)(8√2)
We will go ahead and multiply this by 8, since there are 8 lateral faces:
LA=8(1/2)(6.6)(8√2)
LA = 298.7

Answer:

m < A =

Answers
1. m ∠C = 88°
2. m ∠B = 100°
3. m ∠A = 92°
4. m ∠D = 80°
Explanation:
∠A and ∠C are supplementary angles; therefore:
∠A + ∠C = 180° --- (A)
Since,
∠A = (x+2)°
and
∠C = (x-2)°
Plug-in the values in equation (A):
(A) => (x+2)° + (x-2)° = 180°
=> x° + 2° + x° - 2° = 180°
=> 2x° = 180°
=> x = 90°
Since x = 90°, therefore,
∠A = (x+2)° = 92°,
and
∠C = (x-2)° = 88°
Since ∠B and ∠D are supplementary angles; therefore,
∠B + ∠D = 180°
∠B + (x-10)° = 180°
Since,
x = 90°; therefore,
∠B + 80° = 180°
∠B = 100°
And since,
∠B + ∠D = 180°
and
∠B = 100°
Therefore,
∠D = 180° - 100°
∠D= 80°

We take the interval and we divide it n times:

The area of the i-th rectangle in the right Riemann sum is:

For the first part of our integral we have:
[tex]A_i=\Delta x(i\Delta x)^3=(\Delta x)^4 i^3[/tex]
For the second part we have:
[tex]A_i=-6\Delta x(i\Delta x)=-6(\Delta x)^2i[/tex]
We can now put it all together:

To express the integral from 0 to 3 of the function as the limit of a Riemann sum, divide the interval into [tex]f(x) = x^3 - 6x[/tex] subintervals of equal width, find a Riemann sum, and then take the limit as n approaches infinity.
Explanation:To express the given integral as the limit of a Riemann sum without evaluating, we represent the integral of the function [tex]f(x) = x^3 - 6x[/tex]split the interval [0,3] into n equal subintervals, each of width Δx = 3/n. Then we choose sample points x_i in each subinterval [x_{i-1}, x_i]. The Riemann sum is thus [tex]R = Σ(x_i^3 - 6x_i)Δx[/tex]en from i=1 to n and x_i is any point in the ith subinterval.
As n approaches infinity, which is equivalent to Δx approaching zero, the Riemann sums converge to the integral. The limit of the Riemann sum is then represented as lim_{n to ∞} R, which gives the exact area under the curve f(x) between 0 and 3, but we are not evaluating this limit.
Kevin is 2 times as old as Gabriela. 12 years, Kevin was 6 times as old as Gabriela.How old is Gabriela now
Answers
Final answer:
Gabriela's current age is found by setting up algebraic equations based on the information that Kevin is twice as old as Gabriela now, and was six times as old 12 years ago. Solving the equations, we find that Gabriela is 15 years old.
Explanation:
Finding Gabriela's Current Age:
The problem statement tells us that Kevin is currently 2 times as old as Gabriela and that 12 years ago, Kevin was 6 times as old as Gabriela. To solve for Gabriela's current age, let us use algebra. Let's denote Gabriela's current age as G and Kevin's current age as K. The given information can be translated into the following two equations:
K = 2G (Kevin is 2 times as old as Gabriela now)K - 12 = 6(G - 12) (12 years ago, Kevin was 6 times as old as Gabriela)Substituting the first equation into the second, we get:
2G - 12 = 6(G - 12)
Expanding both sides:
2G - 12 = 6G - 72
Moving all terms involving G to one side and constant terms to the other side, we get:
2G - 6G = -72 + 12
-4G = -60
Dividing both sides by -4 to solve for G:
G = 15
So, Gabriela is currently 15 years old.

a percentage is a number or ratio expressed as a fraction of 100.it is often denoted using the percent sign "%".Given is that a car salesman earns 2% commission on all of his sales. He needs to make $3,000 a month for his living expenses,
Assume that the total dollar amount he must sell to make that in commission each month is ${x}. Then, we can write -
3000 = 2% of {x}
3000 = (2/100) × {x}
{x} = (3000 x 100)/2
{x] = 300000/2
{x} = 150000
