Marina CMI [18]

The average rate of change is also known as the slope. If we are looking to find the average rate of change between x = -1 and x = 2, in order to find the slope between those 2 x values, we need the y's that go along with them. Fill in -1 for x in the function and solve for y: (-1)^3-3(-1)^2-(-1)+3=0. That means that the coordinate is (-1, 0). Fill in 2 for x in the function and solve for y: (2)^3-3(2)^2-(2)+3=-3. The coordinate there is (2, -3). Now we can set up the slope formula to find the average rate of change between those 2 points: \frac{-3-0}{2-(-1)}=\frac{-3}{3}=-1. Therefore, the average rate of change between x = -1 and x = 2 is -1

Answer:

32 goldfish

Step-by-step explanation:

Given:

  • Number of fish tanks = 8
  • Volume of water per fish tank = 5,544 in³
  • Water required by 1 goldfish = min 1,386 in³

Number of fish per tank = water per tank ÷ water per goldfish

                                        = 5544 ÷ 1386

                                        = 4

Therefore, each tank can hold a maximum of 4 goldfish.

Greatest number of goldfish = number of tanks × fish per tank

                                               = 8 × 4

                                               = 32

Question 9 (5 points)
Ad libitum [116K]

9514 1404 393

Answer:

  $3291.60

Step-by-step explanation:

If the loan is amortized in the usual way, the monthly payment is ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t)) . . . . . loan of P at rate r for t years

  A = $15,000(0.081/12)/(1 -(1 +0.081/12)^(-12·5)) ≈ $304.86

The total of payments is ...

  (60 months) × ($304.86/month) = $18,291.60

Then the profit to the bank is ...

  $18,291.60 -15,000 = $3,291.60 . . . bank profit

Featured snippet from the web

A right prism is made up of two identical, parallel bases on the ends, and the faces are perpendicular to the bases. The formula for finding surface area is 2B + hP (where B is the area of one of the bases, h is the prism's height and P is the perimeter of the base)

the +4 turns into -4

6-4=2 the (+4-4 on the left would cancel out)

-2x/2 would cancel out as well

2 divided by 2 = 1

you could have used a scientific calculator on google (for future reference)
