The profitability, P, of a popular restaurant franchise can be modeled by the function P (t) = t4 – 9t3 + 24t2 – 20t, where t is the number of months since the restaurant opened. How many months after the franchise opens will it begin to show a profit?

5 months
3 months
2 months
1 month

Answers

Replace t with the months given as choices to see which one gives a positive value as an answer.

P(1) = 1^4-9(1)^3 + 24(1)^2-20(1) = -4

P(2) = 2^4-9(2)^3+24(2)^2-20(2) = 0

P(3) = 3^4 -9(3)^3+24(3)^2-20(3) = -6

P(5) = 5^4-9(5)^3+24(5)^2-20(5) = 0

P(6) = 6^4-9(6)^3+24(6)^2-20(6) = 96

It shows a profit in month 6 so it would start showing a profit in month 5.

The answer is 5 months

If x = 2y then, 5y - x in terms of y is equal to 3y and when y = 2, the value of 5y - x is 6.

To solve 5y - x in terms of y, we need to substitute the value of x in terms of y. Given that x = 2y, we can replace x with 2y in the expression 5y - x:

5y - x = 5y - (2y)

Now we simplify the expression by subtracting 2y from 5y:

5y - (2y) = 3y

Therefore, 5y - x in terms of y is equal to 3y.

To find the value of the expression when y = 2, we substitute y = 2 into the expression:

3y = 3 * 2 = 6

Thus, when y = 2, the value of 5y - x is 6.

use the following list to find the average or mean, the median, the mode, and the range 10, 15, 5, 8, 6, 6, 2

Answers

Answer:

Mean - 7.43

Median - 6

Mode - 8

Range - 13

Step-by-step explanation:

To find the mean/average, add up all the numbers and divide the sum by the # of data points.  (ex. you have 7 numbers, so you divide the sum of the numbers by 7.)

The median of a set of data is the middle number of ascending numbers in the data.  If there was an even number of data points you would have to add the 2 middle numbers and divide by 2.

The mode is the number that appears most frequently in the data set.

To find the range, just subtract the lowest number in the data set from the greatest number.

Answer:

mean= 7.4, median = 6, mode =6, range = 13

Step-by-step explanation:

mean = 10 + 15 + 5 + 8 + 6 + 6 + 2 ÷ 7

= 52 ÷ 7

= 7.4

median= 2, 5, 6, 6, 8, 10 , 15

6

median is the middle number from ascending order

mode = 6

mode is the number that occurs the most

range = 15 - 2

13

range is the different between the largest and smallest number

fiind the missing value ?

Answers

Step by step process:

Let's solve for x.

y−3=2(x+1)

Step 1: Flip the equation.

2x+2=y−3

Step 2: Add -2 to both sides.

2x+2+−2=y−3+−2

2x=y−5

Step 3: Divide both sides by 2.

2x/2=y−5/2

x=1/2y+(−5/2)

Answer: x=1/2y+(−5/2)

Let's solve for y.

y−3=2(x+1)

Step 1: Add 3 to both sides.

y−3+3=2x+2+3

y=2x+5

Answer:
