1. Cindy did an experiment. She started out with 700 bacteria cells. She found that the growth rate of the bacteria cells was 4.

3%. Create an equation for the situation that would work for any time, x. Type your equation into Desmos to make a graph that represents her experiment. Take a screenshot that includes both the equation and the graph in Desmos. Paste the screenshot to this page or attach it separately to the assignment submission drop box. Please help!!!!

Answer:

  • This is an exponential function of the form y=a(b^x)
  • We will use the following
  • y for the number of bacteria at a given time
  • x for the time
  • a for the starting number of bacteria, which is 700
  • b for the base of the exponent
  • so lets find b, we need the following:
  • r, which will be our rate, which is 4.3% or 0.043, so
  • b=1+r\\b=1+0.043\\b=1.043
  • With this info, let's substitute, and get the equation as the answer: y=700(1.043^x)
  • Put that into desmos, (I attached a screenshot for you)

A) Because the 80 is by itself that would be the start up fee.

B) We are told x is the number of months. Since the X is being multiplied by 30, we know that would be the total monthly cost. This is being added to the 80, which does not have an exponent, so we know this is a single cost, which would be the start up fee.

C) Copying the same format as the given equation above, change the numbers:

f(x) = 20 + 35x

D) I used the same format as the first equation, which meant replacing the start up cost from the original one ( 80) with the start up of the new one (20). Then I changed the monthly cost from the original one (30) with the monthly cost of the new one (35).

E) Replace x in each equation with 8 and calculate the cost of each:

80 + 30(8) = 80 + 240 = $320

20 + 35(8) = 20 + 280 = $300

The second club (club B) is the cheaper option for her.

H=-t^2+95
The y intercept here is 95, and it represented from where the boy threw the ball.

If he threw it from 95 ft above the ground, the best answer for where he is is on a bridge.
His backyard is at 0 ft (sea level). An underground cave is below sea level. A ladder is probably not 95 ft.

Final answer: D
