Answer:
PV= $925
Step-by-step explanation:
Giving the following information:
Money is borrowed at 8% simple interest. After one year, $999 pays off the loan.
To calculate the original value of the loan, we need to use the following formula:
PV= FV/(1+i*n)
PV= 999/(1+0.08*1)
PV= $925

Health officials in Parsnipville are concerned about the recent outbreak of the flu. While scientists are working hard to find a vaccine, the town leaders are turning to you to predict how many people will be sick over time. They hope to find a vaccine in a week. Here are the facts: The epidemic started on Day 0 when Velma and Stanley returned from their exotic jungle vacation with symptoms of the flu. Each day, a sick person infects two additional people. The town of Parsnipville has 3800 citizens.
Answer:
4372 people would have been sick over time.
Step-by-step explanation:
Since the vaccine would be found in a week, then the over time is a week (7 days). Each day, a sick person infects two additional people.
Number of people infected by Velma can be predicted as follows:
Day 1 - 2, Day 2 - 6, Day 3 - 18, Day 4 - 54, Day 5 - 162, Day 6 - 486, Day 7 - 1458
Number of people infected by Velma = 1458 + 486 + 162 + 54 + 18 + 6 + 2
= 2186
Also, number of people infected by Stanley can be predicted as follows:
Day 1 - 2, Day 2 - 6, Day 3 - 18, Day 4 - 54, Day 5 - 162, Day 6 - 486, Day 7 - 1458
Number of people infected by Stanley = 1458 + 486 + 162 + 54 + 18 + 6 + 2
= 2186
Total number of people than can be infected over time = 2186 + 2186
= 4372
Therefore, the predictable number of infected people over time would be 4372. All citizens of Parsnipville would have been infected before the vaccine is available.

A bakery sells a dozen bagels for $8.50 and a dozen donuts for $3.99. Write an expression for the
cost of buying b dozen bagels and d dozen donuts.
Answer:
Total cost = ($8.50b) + ($3.99d)
Step-by-step explanation:
In a bakery, the cost of a dozen bagels = $8.50
and the cost of a dozen donuts = $3.99
1 Dozen = 12 pieces
Let 'b' represents the number of bagels (in dozen) and d represents dozen donuts.
The expression that represents total cost of b dozen bagels and d dozen donuts would be :
Total cost = ($8.50b) + ($3.99d)
what is the value of y in this equation. 3-4y=19
Steps to solve:
3 - 4y = 19
~Subtract 3 to both sides
-4y = 16
~Divide -4 to both sides
y = -4
Best of Luck!

Solve each equation 9-4(2x-1)=45
I think it is done like this but I am not sure.
Simplifying
9 + -4(2x + -1) = 45
Reorder the terms:
9 + -4(-1 + 2x) = 45
9 + (-1 * -4 + 2x * -4) = 45
9 + (4 + -8x) = 45
Combine like terms: 9 + 4 = 13
13 + -8x = 45
Solving
13 + -8x = 45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-13' to each side of the equation.
13 + -13 + -8x = 45 + -13
Combine like terms: 13 + -13 = 0
0 + -8x = 45 + -13
-8x = 45 + -13
Combine like terms: 45 + -13 = 32
-8x = 32
Divide each side by '-8'.
x = -4
Simplifying
x = -4
The solution to the equation 9 - 4(2x - 1) = 45 is x = -4.
We have,
Distribute the -4 to the terms inside the parentheses:
9 - 4(2x - 1) = 45
9 - 8x + 4 = 45
Combine like terms:
13 - 8x = 45
Move the constant term to the other side of the equation by subtracting 13 from both sides:
13 - 8x - 13 = 45 - 13
-8x = 32
Divide both sides of the equation by -8 to isolate the variable:
(-8x) / (-8) = 32 / (-8)
x = -4
Therefore,
The solution to the equation 9 - 4(2x - 1) = 45 is x = -4.

Factor completely
4x^2 - 18x - 36
Answer: 2(2x + 3)(x - 6)
Step-by-step explanation: For any factoring problem you do, your first
task will be to determine if a GCF exists for the original polynomial.
If a GCF does exist, it must be factored out as the first step to the problem.
In the problem you see here, the 3 terms in
the original polynomial have a GCF of 2.
So a 2 must be factored out as your first step.
This leaves you with 2(2x² - 9x - 18).
This does not make your life a whole lot easier however
because you still have a coefficient on the x squared term.
Factoring from here, you get 2(2x + 3)(x - 6).
Answer:
2(x - 6)(2x + 3)
Step-by-step explanation:
There are a few steps to factoring depending on the polynomial.
Step 1. Factor our a common factor if possible.
Every term is divisible by 2, so factor out a 2.
4x^2 - 18x - 36 =
= 2(2x^2 - 9x - 18)
Step 2. We need to factor the quadratic trinomial.
Now we have a quadratic trinomial, in which the x^2 term is not plain x^2, but it has a coefficient of 2.
Our polynomial is of the form ax^2 + bx + c, with "a" not equal to 1.
We have 2x^2 - 9x - 18, so we have a = 2, b = -9, c = -18.
We can try guessing, but instead, I will use the "ac" method.
Step A. Multiply coefficients ac:
ac = 2(-18) = -36
Step B. Now we need two numbers that add to b and multiply to ac.
We need two numbers that add to -9 and multiply to -36.
The numbers are -12 and 3 since (-12)(3) = -36, and -12 + 3 = -9.
We now break up the middle term, -9x, using these two numbers.
= 2(2x^2 - 12x + 3x - 18)
Now we factor by grouping. Factor a common factor out of the first two terms, and factor a common factor out of the last two terms.
= 2[2x(x - 6) + 3(x - 6)]
x - 6 is a common factor inside the brackets, so we factor it out inside the brackets.
= 2[(x - 6)(2x + 3)]
= 2(x - 6)(2x + 3)
