g(x)=-3x^2 + 2x-6
h(x)=-4-x
Find: g(x ) - h(x)
Answer: g(x) - h(x) = (-3x^2 + 2x - 6) - (-4 - x) = -3x^2 + 3x - 2.
Step-by-step explanation: The expression g(x) - h(x) can be found by subtracting h(x) from g(x).
g(x) = -3x^2 + 2x - 6
h(x) = -4 - x
So,
g(x) - h(x) = (-3x^2 + 2x - 6) - (-4 - x) = -3x^2 + 3x - 2.
Calculate the time value, at the end of the fifth year, of a 5-year annuity that pays $200
every month, starting from the beginning of the second month, when the continu-
ously compounded interest rate is 9.959%. Give your answer to the nearest dollar.
Answer:
The time value, at the end of the fifth year, of a 5-year annuity that pays $200 every month, starting from the beginning of the second month, when the continuously compounded interest rate is 9.959%, is $11,828. To calculate this, we can use the formula A = PMT x [((1 + r)n - 1) / r], where PMT is the payment amount, r is the continuously compounded interest rate, and n is the number of payments. In this case, PMT = $200, r = 0.09959, and n = 60. Plugging these values into the formula, we get A = $200 x [((1 + 0.09959)60 - 1) / 0.09959] = $11,828.
any local College 63 of the male students are smokers in 147 or non-smokers the female students 70 or smokers and 130 are non-smokers a male student and a female student from the college are randomly selected for a survey what is the probability that both are smokers
Answer:
To find the probability that both a randomly selected male student and a randomly selected female student are smokers, we can use the formula for conditional probability: P(A and B) = P(A) * P(B|A), where A is the event that the male student is a smoker and B is the event that the female student is a smoker.
First, we need to find the probability that a randomly selected male student is a smoker:
P(A) = (number of male smokers) / (total number of male students) = 63 / (63 + 147) = 63/210
Next, we need to find the probability that a randomly selected female student is a smoker, given that the male student is a smoker:
P(B|A) = (number of female smokers and male smokers) / (number of male smokers) = 70 / 63
Finally, we can find the probability that both students are smokers by multiplying these two probabilities together:
P(A and B) = P(A) * P(B|A) = (63/210) * (70/63) = 0.09
So the probability that both a randomly selected male student and a randomly selected female student are smokers is 0.09 or 9%.

write and solve system of equations - an adult ticket to a museum costs $3 more than a childrens ticket. when 200 adult tickets and 100 childrens tickets are sold, the total revenue is $2100. what is the cost of a childrens ticket
Answer:
$5
Step-by-step explanation:
Let the cost of a children's ticket be x.
The cost of an adults ticket would be x + 3. (adult ticket costs $3 more than a children's ticket.)
200 adult tickets would cost 200(x+3), and 100 children's ticket would cost 100x.
The combined costs of children's ticket and adult would be 200(x+3) + 100x.
Using these information, the equation: 200(x+3) + 100x = 2100 can be formed.
200(x+3) + 100x = 2100
200x + 600 + 100x = 2100
300x = 1500
x = 5
The children's ticket cost $5.
Double check.
200*8 + 100*5 = 2100.
Use properties to rewrite the given equation. Which equations have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p? Select two options. 2.3p – 10.1 = 6.4p – 4 2.3p – 10.1 = 6.49p – 4 230p – 1010 = 650p – 400 – p 23p – 101 = 65p – 40 – p 2.3p – 14.1 = 6.4p – 4
The equations that have the same solution are:
2.3p – 10.1 = 6.49p – 4
230p – 1010 = 650p – 400 – p
23p – 101 = 65p – 40 – p
Options B, C, and D are the correct answer.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We have,
2.3p - 10.1 = 6.5p - 4 - 0.01p
2.3p - 6.5p + 0.01p = 10.1 - 4
2.31p - 6.5p = 6.1
-4.19p = 6.1
p = -6.1/4.19
p = -1.5
Now,
Solve for p.
2.3p – 10.1 = 6.4p – 4
2.3p - 6.4p = 10.1 - 4
-4.1p - 6.4
p = -6.4/4.1
p = -1.6
2.3p – 10.1 = 6.49p – 4
2.3p - 6.49p = 10.1 - 4
-4.19p = 6.1
p = -1.5
230p – 1010 = 650p – 400 – p
230p - 649p = 1010 - 400
-419p = 610
p = -1.5
23p – 101 = 65p – 40 – p
23p - 64p = 101 - 40
-41p = 61
p = -1.5
2.3p – 14.1 = 6.4p – 4
2.3p - 6.4p = 14.1 - 4
-4.1p = 10.1
p = 2.5
Thus,
Equations that have the same solution
2.3p – 10.1 = 6.49p – 4
230p – 1010 = 650p – 400 – p
23p – 101 = 65p – 40 – p

(b) Find the balance after 1 year.
(c) The effective yield of a savings plan is the percent increase in the balance after 1 year. Find the effective yield.
Explain or show work
Answer:
(a) 5.78%
(b) $10,594.63
(c) 5.95%
Step-by-step explanation:
You want the annual rate, the 1-year balance, and the effective yield on an account in which $10,000 is deposited, and the value doubles in 12 years.
(a) Annual rateThe compound interest formula is ...
A = Pe^(rt)
where P is the amount invested at annual rate r for t years, and A is the account balance.
Solving for r, we have ...
ln(A/P)/t = r
The account value will have doubled when A/P = 2, so the rate is ...
r = ln(2)/12 ≈ 0.057762 ≈ 5.78%
The annual rate is about 5.78%.
(b) 1-year balanceThe balance after 1 year is ...
A = 10000·e^(ln(2)/12·1) = 10000·2^(1/12) = 10594.63
The balance after 1 year will be $10,594.63.
(c) Effective yieldThe APR (r) will be ...
A = P(1 +r)^t
10594.63 = 10000(1 +r)¹
r = 10594.63/10000 -1 = 0.059463 ≈ 5.95%
The effective yield is about 5.95%.

Answer:
f'(-3.5) ≈ 0.8292
f'(2) ≈ 5.277
f'(4) ≈ 10.34
Step-by-step explanation:
You want the approximate derivative of f(x) = 8·1.4^x using h=0.001 at x = {-3.5, 2, 4}.
DerivativeThe derivative is approximated by the formula ...
[tex]f'(x)\approx\dfrac{f(x+h)-f(x)}{h}\\\\f'(x)\approx\dfrac{f(x+0.001)-f(x)}{0.001}\qquad\text{for $h=0.001$}\\\\f'(x)\approx\dfrac{8\cdot1.4^{x+0.001}-8\cdot1.4^x}{0.001}\qquad\text{using the given $f(x)$}[/tex]
The calculation for different values of x is tedious, but not difficult.
For example, ...
f'(-3.5) = (8·1.4^-3.499 -8·1.4^-3.5)/0.001 = (2.4648358 -2.4640066)/0.001
= 0.0008292/0.001
f'(-3.5) = 0.8292
The remaining f'(x) values are shown in the attached table in the column f₁(x₂).

Additional comment
When function evaluation is repeated for different values, it is usually convenient to let a calculator or spreadsheet do the math. You can enter the formula once and have it evaluated as many times as you need.
The formula shown can be simplified to f'(x) ≈ 8000(1.4^(x+.001) -1.4^x), reducing the tedium by a small amount. The second attachment shows a different calculator using this formula.

If a variable needs to be eliminated, to solve -7x - 10y = -83 4x - 10y = 16, the correct first step is to:
Subtract to eliminate y.
In order to solve a system of linear equations, we can use elimination method. The goal of elimination method is to simplify the system of equations by making one of the variables disappear or equal to zero.
Here, the system of equations is:
-7x - 10y = -834x - 10y = 16To eliminate one of the variables, we can add or subtract the equations so that one of the coefficients cancels out.
In this case, we want to eliminate y. We can do that by subtracting the first equation from the second equation.
When we subtract the first equation from the second equation, the y-term will cancel out because the coefficients are the same:
-7x - 10y = -834x - 10y = 16--------- (subtract the two equations)
11x = 99
Now, we only have one variable, x, and we can easily solve for it:
x = 9

The explicit formula for aₙ is a formula for the nth term of this sequence aₙ = 8n + 17.
What is the explicit formula?
The explicit formulae for L-functions are relations between sums over the complex number zeroes of an L-function and sums over prime powers, introduced by Riemann for the Riemann zeta function.
The formula for the nth term of this sequence is a_n = 8n + 17.
This means that each term in the sequence is equal to 8 multiplied by the position of the term (n) plus 17.
For example, the first term (n = 1) is 25, which can be calculated as 8 * 1 + 17 = 25.

These pollen sources are categorized as grasses, weeds, and treesIf the number of weeds is 7 less than thrice the number of grasses, and the number of trees is 3 more than thrice the number of grasses, find the number of grasses, weeds, and trees that are major pollen sources.
Answer: 16 grasses, 41 weeds, and 51 trees
Step-by-step explanation:
You can use a variable for the different pollen sources. Use g for grass, w for weeds, and t for trees. w=3g-7. t=3g+3. g+w+t=108. In that last equation, you can substitute other values for w and t. g+(3g-7)+(3g+3)=108. combine like terms to get, 7g-4=108. This equation simplifies to g=16. Substitute 16 for g in the first 2 equations, and find that w=41, and t=51.

The three methods are used to select a sample from a larger population in order to make inferences about the population as a whole.
Probability-proportional-to-size sampling is a method where the probability of an item being selected is proportional to its size. In this case, the size is represented by the dollar amount of the sale.
Systematic selection involves selecting items at regular intervals. In this case, the starting point is 13 and the interval is 30. Every 30th item is selected, starting from the 13th item.
The starting dollar is $17,240 and the interval is $220,000. Every item with a sales amount that falls within the interval is selected with a probability proportional to its size.
The random-number table selection technique involves using a random number table to select items. The last four digits of the invoice number are used to determine which item is selected.
The selection process starts at row (0004) and column (01) and continues across the row and then down to the next row.
The probability of an item being selected in each method differs and is important in ensuring a representative sample is obtained.

The solution to the system of equations is x = (y + 2) / 3 and y = 2.5.
What is the equations ?Equations are mathematical statements that express the relationship between two or more variables. An equation typically consists of an equal sign, two expressions containing the variables, and the equals sign is used to show that the two expressions on either side of it are equal in value. Equations are used to solve problems, make predictions, and describe patterns.
Let's start by solving for x in the first equation:
y = 3x - 2
Add 2 to both sides of the equation:
y + 2 = 3x
Divide both sides of the equation by 3:
(y + 2) / 3 = x
Now that we've solved for x, we can substitute x into the second equation.
y = x + 2
Substitute (y + 2) / 3 for x:
y = (y + 2) / 3 + 2
Simplify the left side of the equation:
y = (y + 2 + 3) / 3
Multiply both sides of the equation by 3:
3y = (y + 5)
Subtract y from both sides of the equation:
2y = 5
Divide both sides of the equation by 2:
y = 5 / 2
y = 2.5

x= the time
to get the rate of change do the following:
add 1 to the percentage of change (only if value is growing)
subtract the percentage from one (only if value is decaying)
Since the printer is depreciating it is a decay.
The rate of change for this problem is showed below.
1-0.05
0.95 is the rate of change.
Below is the equation for the problem.
y=35000(0.95)^4 Work the problem.
Y=35000(0.814506250
Y=28507.71875 Since we are working with money we round to two decimal places.
The printer's value after four years is $28,507.72.
i am 20 years older than twice my daughter's age, and i am 34 years old. How old is my daughter?
Your daughter is 7 years old.
Step-by-step explanation:1. Express the ages as variables.
Let "x" be your age.
According to the statement, your age is 34. Thus, x= 34.
Let "y" be the age of your daughter.
According to the statement, your daughter's age is given by the following equation:
[tex]2y+20=x\\ \\2y+20=34[/tex]
2. Solve the equation for "y". Start by subtracting "20" on both sides of the equation.[tex]2y+20-20=34-20\\ \\2y=14[/tex]
3. Divide by "7" on both sides of the equation.[tex]\frac{2y}{2} =\frac{14}{2} \\ \\y=7[/tex]
4. Verify the answer.Let's see if number 7 makes the original condition be true.
So, you are 20 years older than twice your daughter's age. Let's multiply your daughter○s age by 2 and add 20, it should return your age (34).
[tex]2(7)+20=\\ \\14+20=\\ \\34[/tex]
That's correct, it means that 7 is the correct answer.

What is negative 2.48 rounded to the nearest hundredth
Answer:
it's already rounded to the nearest hundredth
Step-by-step explanation:
because there is no numbers after the hundredth.
Cindy is making fruit salads and fruit smoothies. The salad recipe requires 1/3 cup of strawberries and the smoothie recipe calls for 3/4 cup of strawberries. Her friend Borling is helping make the food.How many cups of strawberries would be required for both girls and two of their friends?
The fruit salad recipe requires 1/3 cup of strawberries and the smoothie recipe requires 3/4 cup of strawberries. So in total, 1/3 + 3/4 = 5/12 cup of strawberries are required for both recipes.
Now we know that Cindy and Borling are both making the recipes. So we need to multiply the 5/12 cup of strawberries by 2 to find out how many cups of strawberries are needed for both of them.
5/12 cup * 2 = 10/12 cup or 5/6 cup of strawberries.
Now if two more friends are joining them, we need to multiply the 5/6 cup of strawberries by 4 to find the total number of cups of strawberries required for all 4 of them.
5/6 cup * 4 = 2 and 1/6 cups.
So in total, 2 and 1/6 cups of strawberries would be required for both girls and two of their friends.
Answer:
Find x.
1/3+3/4=x
4/12+9/12=x
13/12=x
1 1/12 cups of strawberries for one person.
3*1 1/12=3 1/4
3 1/4 cups of strawberries in total for both girls and two of their friends.Step-by-step explanation:

What are the zeros of the function f(x)=x4-x2-2
+/-3,+/-i
+/-2,+/-i
+/-squareroot of 2, +/- i
+/-squareroot of 3, +/- i
Please explain :)
The zeros of the function f(x) = x^4 - x² - 2 are given as follows:
+/-squareroot of 2, +/- i
How to obtain the zeros of the function?The function for this problem is defined as follows:
f(x) = x^4 - x² - 2
The zeros are the values of x for which:
f(x) = 0.
Applying the transformation y = x², the function can be reduced to a quadratic function as follows:
y² - y - 2 = 0.
Hence:
(y - 2)(y + 1) = 0.
Meaning that the solutions for y are given as follows:
y - 2 = 0 -> y = 2.y + 1 = 0 -> y = -1.Then the solutions for x are given as follows:
y = -1 -> y = x² -> x = +/- iy = 2 -> x = +/-squareroot of 2Meaning that the third option is correct.
