After six years, the population will grow to 586,455 if compounded annually at a rate of 7.5%.
This is exactly like a compound interest problem where the interest rate is 7.5% compounded annually for 6 years.
If we use the compound interest formula A = P(1+r/n)nt where A is the end amount to be found, p = initial amount (p= 380,000), n = number of times the interest is compounded annually (n= 1) and t is the time in years (t=6)
A = 380,000(1 + .075/1)1(6)
A = 380,000(1.075)6
A = 586,454.58 people
Rounded to the nearest whole number
the population after 6 years should be
586,455 people
Hence we get the required answer.

What is parallel slope intercept form?
Parallel slope intercept form is a form of linear equation that describes a line parallel to a given line with slope m.
It is written as y = mx + b, where m is the slope of the line and b is the y-intercept of the line. This form is useful for finding equations of lines that are parallel to a given line.
y = mx + b
y = mx + b is an equation in the form of a straight line, where m is the slope of the line and b is the y-intercept of the line. This form can be used to determine the equation of a line that is parallel to a given line. The equation can be re-arranged to solve for x, if needed. To solve for x, the equation can be rewritten as x = (y - b) / m.

The coordinates of the vertices after a reflection over the line x = 2.
D = (8, 5)
E = (6, 5)

What is a reflection?There are two ways of translation.
Along x-axis:
(x, y) – (x, -y)
Along y-axis:
(x, y) - (-x, y)
We have,
The coordinates:
D = (-4, 5)
E = (-2, 5)
F = (0, 8)
G = (3, 8)
The line x = 2.
We count the units from the line x = 2.
After the reflection, the number of units of each coordinate from the line
x = 2 must be equal to the number of units from the line x = 2 before the reflection.

Ruby is going to a carnival that has games and rides. Each game costs $1.25 and each ride costs $2.50. Ruby spent $15 altogether at the carnival and the number of games she played is twice the number of rides she went on. Graphically solve a system of equations in order to determine the number of games Ruby played, x, and the number of rides Ruby went on, y.
$15 = 1.25x + 2.50y
x number of games, y = number of rides
Graphing this will show a line with coordinates (x, y) on it who 'fit' in this equation to make it = 15
I graphed points where both x and y are whole numbers.
These are answers to the equation that make it = 15.
Graph the line 2x = y (2 times the number of games is the number of rides)
Where the lines intersect is where number of rides is twice taht of games, and the price is 15.
Visually, we can determine that they intersect at (2.4, 4.8)
To verify that this is correct, plug them into the first function to see if this gives you 15.
It does equal 15.
While these are not whole numbers, they do make the equations true, but in the real world we would not have numbers like this.

The square of given expression √1 ( square root of 1 ) is equal to 1.
As given in the question,
Given expression is equal to √1 ( square root of 1 )
To calculate the square of √1 we have,
Let us consider variable x is equal to √1
x = √1
Now take square on both the sides of the given expression we get,
x² = (√1 )²
⇒ x² = √1 × √1
Multiplying square root of 1 to square root of 1 is equal to 1 we get,
or use law of exponent :

3. The length and breadth of a hall are 28 m and 21 m respectively. If the ratio of its length to its height is 7:6, find the ratio of its breadth to its height.
Answer: The ratio of the breadth to the height of the hall is 7:8
Step-by-step explanation:
The ratio of the length to the height of the hall is 7:6, which means that if the length of the hall is represented by 7, the height is represented by 6. We can write this as a proportion as follows:
7/6 = L/H
We know that the length of the hall is 28 meters, so we can substitute this value for L in the proportion to find the height:
7/6 = 28/H
Solving for H, we get:
7/6 = 28/H
7H = 168
H = 168/7 = 24
The height of the hall is 24 meters.
The ratio of the breadth of the hall to its height is the same as the ratio of 21 to 24, which simplifies to 7:8. Therefore, the ratio of the breadth to the height of the hall is 7:8.

n = 3;
-2 and 6+4i are zeros;
f(2)=128
Answer:
f(x) = x³ -10x² +28x +104
Step-by-step explanation:
You want a cubic polynomial f(x) with real coefficients, and its graph, such that one root is -2, another is 6+4i, and f(2) = 128.
Conjugate rootsA polynomial with real coefficients will have complex (or radical) roots that are conjugate pairs. That means the root 6+4i will be paired with a root 6-4i. The factored form of the required polynomial will be ...
f(x) = a(x -(-2))(x -(6 +4i))(x -(6 -4i))
f(x) = a(x +2)(x² -12x +52)
Scale factorWe can use the given value of f(2) to find the scale factor, a.
f(2) = 128 = a(2 +2)(2² -12·2 +52) = a(4)(32) = 128a
a = 1 . . . . . divide by 128
The required polynomial is ...
f(x) = (x +2)(x² -12x +52)
f(x) = x³ -10x² +28x +104

What is the first thing a lender might do if a borrower is late with a payment?
Answer:
they will probably contact them orrr charge late fees
The first thing a lender might do if a borrower is late with a payment is to send a reminder.
This reminder will usually be a phone call, email, or letter. The reminder will typically state the amount that is due, the due date, and any late fees that may be charged.
If the borrower does not make the payment after receiving the reminder, the lender may then contact the borrower directly. This contact may be made by a phone call, email, or letter. The lender may also try to work with the borrower to come up with a payment plan.
If the borrower still does not make the payment, the lender may then report the borrower to the credit bureaus. This will have a negative impact on the borrower's credit score. The lender may also start legal proceedings to collect the debt.
The specific steps that a lender will take if a borrower is late with a payment will vary depending on the lender's policies and the borrower's situation. However, sending a reminder is usually the first step.
Here are some additional things that a lender might do if a borrower is late with a payment:
Charge late fees.
Terminate the loan.
Sue the borrower.
Foreclose on the borrower's property.
It is important to note that the lender's actions will also depend on the terms of the loan agreement. The loan agreement will typically specify what happens if a borrower is late with a payment.
If you are a borrower who is late with a payment, it is important to contact your lender as soon as possible. You should try to work out a payment plan with the lender. If you do not make the payment, the lender may take legal action against you.

At least Eight yards need to raked to earn minimum $52. The equation of model is $6.50 Y≥ $52. So, the correct answer is option(C).
The total earned income by rake leaves in your neighborhood after school is $6.50 per yard. The Minimum amount that you want to earn = at least $52
We have determined a equation of model for the given situation.
Let Y be the number of yards raked to earn at least $52. We have one yard raked which implies to earn $6.50
So,for Y yards raked it implies to earn $6.50× Y. But Y has to rake in atleast $52 , here the minimum is to earn either $52 or more than $52. So,Y($6.50 ) ≥ $52
dividing both sides by $6.50 we get,
Y ≥ 52/6.50
=> Y ≥ 52/6.50 = 8

A blimp is fully expanded when it contains 35,000 cubic feet of gas. If the blimp is inflated with 28,700
cubic feet of gas, what percent full is it?
Answer: The blimp is 82% full
Step-by-step explanation:
To find the percentage of the blimp that is filled with gas, we need to divide the volume of the gas that is in the blimp by the total volume of the blimp and then multiply the result by 100%.
The blimp is filled with 28,700 cubic feet of gas, and it has a total volume of 35,000 cubic feet when fully expanded, so the percentage of the blimp that is filled with gas is 28,700 / 35,000 = 0.82.
To express this as a percentage, we need to multiply the result by 100%, so the blimp is 82% full.
Here's the complete solution:
The blimp is filled with 28,700 cubic feet of gas.
The blimp has a total volume of 35,000 cubic feet when fully expanded.
Therefore, the percentage of the blimp that is filled with gas is 28,700 / 35,000 = 0.82.
To express this as a percentage, we multiply the result by 100%, so the blimp is 82% full.
