The activity type would be the input and the cost would be the output. Because there are two different costs for the same activity, this would not be a function.
Answer:
or in "simple" form
Step-by-step explanation:
a(2) = a(1) * (2/3) = 20*(2/3) = 40/3
a(3) = a(2) * (2/3) = 40/3*(2/3) = 80/9
Answer:
Molly earned $856 on the first day.
Step-by-step explanation:
From the information given, you know that over 3 days Molly earned $2,568 which is:
x+y+z=2568, where:
x is the amount earned on the first day
y is the amount earned on the second day
z is the amount earned on the third day
Also, you know that she earns twice as much money on the first day then the second day, which is: x=2y and that she earns 3 times as much money than the second day on the 3rd day, which is: z=3y.
Now you can replace x and y in the first equation and solve for y:
2y+y+3y=2568
6y=2568
y=2568/6
y=428
No, you can replace the value of y to find x and z:
x=2(428)
x=856
z=3(428)
z=1284
According to this, the answer is that Molly earned $856 on the first day.
Answer:
I believe this would be the correct answer. It has been a while since I have done a problem like this.
The range of the function is
{-7,2,3,8}.
