Answer: The second to last option I think
Step-by-step explanation:
Answer:
Step-by-step explanation:
10% discount means you pay 90% of the original cost x.
90% of x = $40.50
0.90x = $40.50
x = $40.50/0.90 = $45
:::::
total cost = 1.065·$40.50 ≅ $43.13
Answer:
See below
Step-by-step explanation:
<u>Point -slope form is:</u>
By having one set of coordinates and knowing the value of the slope (m in the equation) you can use the form.
<u>How to find the slope?</u>
Here you need 2 points: Point 1 with coordinates x1, y1 and point 2 with the coordinates x2, y2
<u>Use the formula:</u>
<u>Example:</u>
- m = -5, and one of the points has coordinates (9, 2) then point-slope form is:
I got 48-(-12) equals to 60
Answer:
Option D:

Step-by-step explanation:
Differential equation:
For the population in function of the time, is:

The population P of rabbits on a small island grows at a rate that is jointly proportional to the size of the rabbit population and the difference between the rabbit population and the carrying capacity of the population
Carring capacity is 2400.
This means that the differential equation is kP(size of the population multiplied by the constant) multiplied by 2400 - P(difference between the population and the carrying capacity). So

So the answer is given by option D.
