Answer:
-93
Step-by-step explanation:
Step one:
given the expressions
[tex]f(x) = -4x + 7\\\\g(x) = 2x^2 + 5x- 8[/tex]
we want (fog)(-3).
but (fog) is
[tex]f(x) = -4x + 7\\\\\ (fog)=-4(2x^2 + 5x -8) + 7\\\\ (fog)=-8x^2-20x+32+7[/tex]
Step two:
fog(-3)= put x= -3 in (fog)(-3)=-8x^2-20x+32+7
[tex](fog)(-3)=-8x^2-20x+32+7\\\\ (fog)(-3)=-8(-3)^2-20(-3)+32+7\\\\ (fog)(-3)=-8*9+60+32+7\\\\ (fog)(-3)=-72-60+32+7\\\\ (fog)(-3)=-93[/tex]

−4(m+3)=24
What does m=
Answer: m= -9
Step-by-step explanation: First use distributive property, -4(m) is -4m and -4(3) is -12. Then you have -4m -12 =24. Then use 12 and add it to the other side of the equation, cause of the subtraction sign, 12+24=36. Then you have -4m=36. Then divide the 4 to get the m by its self. 36 divided by -4 is -9. Your answer is m=-9

Answer:
f(-4) = -8
Step-by-step explanation:
Okay fo if f(n) is f(-4), then n = -4.
f(-4) = 3/4n - 5
f(-4) = 3/4 (-4) -5
f(-4) = -3 - 5

Joe borrowed $4,000 from the bank at a rate of 7% simple interest per year. How much interest did he pay in 4 years?
Answer:
1,120 dollars interest will be paid by Joe in 4 years
Step-by-step explanation:
4,000 times 7 ( 0.07 ) is 280, and 280 times 4 is 1,120
when you convert 10000 present dollars into future dollars of year 15 if the inflation rate is 77% per year, the result is equal to __________.
Answer:
$125,500
Step-by-step explanation:
From the question we are given the following
Present amount = 10000
Inflation rate = 77%
Time = 15years
Using the simple interest method n
Get the inflation amount after 15years
SI = Principal × Rate ×Time/100
SI = 10000×77×15/100
SI = 100×77×15
SI= $115500
The amount after 15years = Present amount + interest
Amount after 15years = 10000+115500
Amount after 15years = $125500
Hence the required result is equal to $125,500

A company ships gift baskets that contain apples and pears the distributions of weight for the apples the pears and baskets are each approximately normal with mean and standard deviation for each distribution as shown in the table below the way to the items are assumed independent let the random variable W represent the total weight for apple six pairs in one basket which of the following is closest standard deviation of W
Answer:
1.97
Step-by-step explanation:
Following are the solution to the given points:
Assume A, P, and B is the masses of apples, pears, and basket, respectively.
[tex]\to W = 4A + 6P + B[/tex]
Calculating the mean of W:
[tex]\to \bold{W = E(W) }[/tex]
[tex]\bold{= E(4A + 6P + B)} \\\\ \bold{= 4E(A) + 6E(P) + E(B)}\\\\\bold{= 4 \times 4.72 + 6 \times 5.41 + 13.52} \\\\ \bold{= 18.88 + 32.46 + 13.52} \\\\ \bold{= 64.86 }[/tex]
Calculating the variance of W:
[tex]\to \bold{W=Var(W)}\\\\[/tex]
[tex]\bold{= Var(4A + 6P + B)}\\\\ \bold{= 42 Var(A) + 62 Var(P) + Var(B)}\\\\\bold{= 16 \times 0.22 + 36 \times 0.182 + 1.882}\\\\ \bold{= 3.52 + 6.552 + 1.882}\\\\ \bold{= 5.3408}[/tex]
Calculating the standard deviation of W:
[tex]\to \bold{W= \sqrt{5.3408}= 2.311017}[/tex]
The linear combination of Normal random variables is known to follow the normal distribution.
[tex]\to \bold{W \sim N(64.86 , 2.311017)}[/tex]
Calculating the Probability of the Total Weight is more difficult.[tex]\to \bold{67 = P(W > 67)}[/tex]
[tex]\bold{= P[ Z > \frac{(67 - 64.86)}{ 2.311017}]}\\\\\bold{= P[Z > 0.93]}\\\\\bold{= 0.1762}[/tex] (Using Standard Normal distribution)
Therefore, the final answer is "64.86, 2.311017, and 0.1762".

A ________ function specifies the relationship between the demand for a product LaTeX: x and the price of the product LaTeX: p.
Answer:
Price demand function
Step-by-step explanation:
The price demand function is the function in which there is a relationship between the demand and the price of the product
The Price demand function is
[tex]= Price \times demand[/tex]
[tex]= p \times x[/tex]
hence, the price demand function represents that there is a relationship that lies between the demand and the price

A family wants to purchase a house that costs $110,000. They plan to take out a $100,000 mortgage on the house and put $10,000 as a down payment. The bank informs them that with a 15-year mortgage their monthly payment would be $761.52 and with a 30-year mortgage their monthly payment would be $574.01. Determine the amount they would save on the cost of the house if they selected the 15-year mortgage rather than the 30-year mortgage.
Answer:
you do 761.52 times 15.
then 574.01 times 30
which ever number is lowest is the one where you save more money. e.g IF the 15 times 761.52 is lower then the 30 times 574.01 then you take them away from each other.The answer to that is how much ur saving.

If the measure of angle 1= (6x+25) and the measure of angle 4= (10x-11) find the measure of angle 1
The measure of angle 1 is 79°
Given:
Value of angle 1 = (6x + 25)
Value of angle 4 = (10x - 11)
Find:
The measure of angle 1
Computation:
In the absence of complete question,
Assume;
Angle 1 = Angle 4
So,
6x + 25 = 10x - 11
10x - 6x = 25 + 11
4x = 36
x = 36 / 4
Value of x = 9
By putting value of x in angle 1
Value of angle 1 = (6x + 25)
Value of angle 1 = 6(9) + 25
Value of angle 1 = 54 + 25
Value of angle 1 = 79

You have a coupon for $4.00 off of your purchase totals more than $15.00 or %10 off if the total is more than $20.00. The food sales tax is 3%. What is your total purchase?
Cheese:$1.99/lb

Potato chips:$1.99/ea Or 2 for $3.00
Salsa:$1.39/container
Be sure to include in your response.
The steps you followed to complete your computations.
The choice you made regarding which discount to use.
The total cost of your purchase.
The total purchase is $18.90.
What is the total purchase?A discount would reduce the cost of the purchase. A tax increases the cost of the purchase.
The first step is to determine the total cost of the items purchased.
Total cost = (cost of lb of cheese x lb bought) + (cost of sliced ham x lbs bought) + (cost of bread x loaves bought) + (cost of a bag of potato chips x number of bags bought) + (cost of one salsa container x number of containers bought)
(1.99 x 1/2) + (3 x 3.29) + (1.59 x 2) + (2 x $3) + (1.39 x 1) = $20.39
Since, the total cost is greater than $20 she qualifies for the 10% discount
Total cost after the discount = (1 - 0.1) x $20.39
0.9 x $20.39= $18.35
Cost after the tax = (1 + 0.03) x $18.35
1.03 x $18.35 = $18.90
