George has opened a new store and he is monitoring its success closely.


He has found that this store’s revenue each month can be modeled by r(x)=x2+6x+10 where x represents the number of months since the store opens the doors and r(x) is measured in hundreds of dollars.


He has also found that his expenses each month can be modeled by c(x)=x2−4x+5 where x represents the number of months the store has been open and c(x) is measured in hundreds of dollars.




What does (r−c)(4) mean about George's new store?





The new store will have a profit of $2300 after its fourth month in business.


The new store will sell 4500 items in its fourth month in business.

Answer:

x = [tex]i\sqrt{55} , -i\sqrt{55}[/tex]

Step-by-step explanation:

x^2 + 8^2 = 9

Simplify the 8^2

x^2 + 64 = 9

Subtract 64 from both sides

x^2 = -55

Take the square root from both sides

x = +/- [tex]\sqrt{-55}[/tex]

Simplify

x = [tex]i\sqrt{55} , -i\sqrt{55}[/tex]

Answer:

5 Hours

Step-by-step explanation:

Assuming their time is cut in half (roughly), you could do 1 + 2 + 2 = 5

It would take 1.1 hours for all working together, option B is correct.

Two or more expressions with an Equal sign is called as Equation.

We use the formula 1 / (time taken by all three to complete the job) = (1 / time taken by Laine) + (1 / time taken by Leslie) + (1 / time taken by Lance)

Plugging in the values given in the question, we get:

1 / (time taken by all three) = (1 / 2) + (1 / 4) + (1 / 5)

To simplify this equation, we first find a common denominator, which is 20.

Then we can rewrite the fractions:

1 / (time taken by all three) = (10 / 20) + (5 / 20) + (4 / 20)

1 / (time taken by all three) = 19 / 20

Multiplying both sides by 20, we get:

time taken by all three = 20 / 19

Hence, it would take 1.1 hours for all working together,

Step-by-step explanation:

F(x) problems or function problems are input/output questions. You put the X value in for X in F(x) to get an output. In this question a graph is used. In this case the question gives a table, so you can simply find the inputs and outputs based on a pattern.

In the X-values or the input values: -4, -2, 0

You can keep going by two: 2, 4

In the F(x) values or output values: 1, 3, 5

Answer:

150 degrees

Step-by-step explanation:

Let's call the angle in the triangle next to the 78 A, the one next to the 132 B, and the one next to the x C. You know that the measure of angle A is 180-78=102 because they are linear pairs. Similarly, the measure of angle B is 180-132=48 degrees. Because all of the angles in a triangle must add up to 180 degrees, C must be 180-102-48=30 degrees. Finally, since x and C are linear pairs, x's angle measure must be 180-30=150 degrees. Hope this helps!

Answer:

C, at least that's what I think.

It will take 7 gallons of gas to drive from Central City to Smithville to Jonesburg in a car that gets 30 miles per gallon.

To calculate the total amount of gas needed to drive from Central City to Smithville to Jonesburg, we need to add up the distances for each leg of the trip and then divide by the car's mileage per gallon.

Central City to Smithville: 85 miles

Smithville to Jonesburg: 125 miles

Total distance: 85 + 125 = 210 miles

Given the car gets 30 miles per gallon, divide total distance by mileage per gallon:

Total gallons of gas needed = 210 miles ÷ 30 MPG = 7 gallons

Therefore, it will take 7 gallons of gas to drive from Central City to Smithville to Jonesburg in a car that gets 30 miles per gallon.

Given: LM bisects [tex]\angle JLK[/tex]

To find: LJ

Solution:

According to angle bisector theorem,

an angle bisector of a triangle divides the interior angle's opposite side into two segments that are proportional to the other two sides of the triangle.

In [tex]\Delta JKL[/tex], LM bisects [tex]\angle JLK[/tex]

Using angle bisector theorem,

[tex]\frac{LK}{LJ}=\frac{KM}{JM}\\\frac{LK}{LJ}=\frac{KM}{JK-MK}\\\frac{8}{x+3}=\frac{4}{x-4}\\8(x-4)=4(x+3)\\8x-32=4x+12\\8x-4x=12+32\\4x=44\\x=\frac{44}{4}=11[/tex]

Sale Price :160 | 180 | 200 | 220 | 240 | 260 | 280

New home     : 126 | 103 | 82 | 75 | 82 | 40 | 20

A.) state the linear regression function that estimates the number of new homes available at a specific price.

B.) state the correlation Coefficient of the data, and explain what it means in the context of the problem

Answer:

Y = -0.79X + 249.86

R = -0.9543

Step-by-step explanation:

Sale Price :160 | 180 | 200 | 220 | 240 | 260 | 280

New home     : 126 | 103 | 82 | 75 | 82 | 40 | 20

Calculate the Linear regression equation :

Using the linear regression calculator :

The linear regression equation is :

Y = -0.79X + 249.86

The correlation Coefficient 'R' measures the strength of statistical relationship between the relative movement of two variables. The The value of R is -0.9543 in the question above.

This is a strong negative correlation, which means that high sales price of homes scores correlates with low number of new homes  scores (and vice versa). Homes with high sales price have fewer number of new homes.

The correct answer to the given table based on the linear regression is:

This refers to the number between -1 and +1 where the interdependence of two variables are shown.

Hence, based on the given table:

Sale Price :160 | 180 | 200 | 220 | 240 | 260 | 280

New home    : 126 | 103 | 82 | 75 | 82 | 40 | 20

To find the Linear regression equation :

Y = -0.79X + 249.86

R= -0.9543

Hence, we can see that the correlation coefficient "R" is used to show the statistical relationship between the two variables.

As a result of the strong negative correlation, then there would be higher prices for homes and lower number of new homes.

Answer:

q = 270 degrees + 360n  where n is an integer

Step-by-step explanation:

2 sin q + 3 = sin q + 2

Subtract sin q from each side

2 sin q - sin q + 3 = sin q + 2

sin q + 3 = 2

Subtract 3 from each side

sin q +3-3 = 2-3

sin q = -1

Take the inverse sin of each side

sin ^-1 (sin q) = sin^-1 (-1)

q = 270 degrees + 360n  where n is an integer

Final answer:

Triangle B is the translation of triangle X as it is moved 3 units down and 4 units to the left.

Explanation:

The question involves finding a triangle that is a translation of another triangle on a coordinate plane. A translation in geometric terms means moving a shape in the plane without rotating or resizing it.

According to the given information, triangle X is translated 3 units down and 4 units to the left to form triangle B.

Based on this information, triangle B is the translated figure of triangle X, and thus it is the correct answer.

The cost of each ticket is $4.

Here we know that the family buys 6 tickets, and they also pay $3 for a parking fee.

The total amount that they spend is $27.

If we remove what the paid for the parking fee, we only will have the cost of the 6 tickets, then we have:

$27 - $3 = $24

Now, we divide this by the number of tickets bought:

$24/6 = $4

Each ticket costs $4.
