Find an equation of the line. Write the equation using function notation.
Through (8,8); perpendicular to 5y = x - 10
Answer:
f(x) = -5x +48
Step-by-step explanation:
A fairly easy way to write the equation of the perpendicular line is to swap the x- and y-coefficients, negating one of them. Then choose the constant in the equation to make it true at the given point.
Swapped coefficientsIn this instance, we find it convenient to leave the coefficient of y as positive.
5y = x -10 . . . . . . original equation
y = -5x +c . . . . . . with coefficients swapped, x-coefficient negated
New constantAt the given point, the equation becomes ...

When you start your career, you decide to set aside $250 every month to deposit into an investment account. The investment firm claims that historically their accounts have earned an annual interest rate of 9.0% compounded monthly. Assuming this to be true, how much money will your account be worth after 20 years of depositing and investing? Round your answer to the nearest cent. Do not include labels or units. Just enter the numerical value.
After 20 years of depositing and investing there will be 168474.01 dollars in your account.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
The formula for calculating how much money will your account be worth after 20 years of depositing and investing is:
P = $250, r = 9% = 0.09, t = 20 years, n = 12 and PMD = $250(per month deposit)
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}+\dfrac{PMD((1+\dfrac{r}{n})^{nt}-1)}{\dfrac{r}{n}}[/tex]
[tex]\rm A = 250(1+\dfrac{0.09}{12})^{12\times20}+\dfrac{250((1+\dfrac{0.09}{12})^{12\times12}-1)}{\dfrac{0.09}{12}}[/tex]
A = 1502.287 + 166971.717
A = $168474.01
Thus, after 20 years of depositing and investing there will be 168474.01 dollars in your account.

The bisection method is being used to calculate the zero of the following function between x = 0 and x = 1.
The bisection method will converge to the solution after three iterations.
How to illustrate the information?It should be noted that after one iteration, x1 will be:
= (1 + 9)/2
= 10/2
= 5
Since f(x¹) > 0, x² will then replace x1. Now x0 = 1 and x1 = 5.
After the second iteration, x2 will be:
= (1 + 5)/2
= 3
Also, this is greater than 0. The third iteration will be:
m= (1 + 3)/2
= 2.
Now, f(2) = 2⁴ -2³ - 2² - 4
= 0
Therefore, the method converges exactly to the root in 3 iterations.

What is the factored form of 8x² + 12x?
O 4(4x² + 8x).
O 4x(2x + 3)
O8x(x + 4)
O 8x(x² + 4)
Answer:
Step-by-step explanation:
Solution
The factored form is going to be the HCF (highest common factor)
The fest way to do this is to turn this into primes.
8x^2 + 12x
8x^2 = 2*2*2*x*x
12x = 2 * 2 * x
Now bold the HCF.
8x^2 = 2*2*2*x*x
12x = 2 * 2 * x
The HCF = 2*2*x
Divide that into the original question to determine the second factor.
8x^2 / 4x = 2x
12x / 4x = 3 Notice how the x-s cancel

How to solve geometric progression?
Each month, there is an increase by a factor of 0.06 of the previous months model.
From geometric sequence formula of aₙ = ar^(n - 1),
where;
a is first term

aₙ is nth term
we have;
