Answer:
Cost for 13 rides: $92
Cost for r rides: I am guessing it would be 40+4r
Step-by-step explanation:
If you automatically pay 40 dollars to get in, then that is the constant, and paying 4 dollars per ride is a coefficient, so that would be multiplied by how many rides you go on, the variable. Once you plug those into the equation above, you would get 92 dollars for the thirteen rides.
Answer:
They are equivalent
Step-by-step explanation:
3/6 is equal to 1/2
2/4 is equal to 1/2
Answer:
(0,3) and (5,0)
Step-by-step explanation:
Given:
The table of values of an exponential function.
To find:
The missing values in the exponential function.
Solution:
The general exponential function is defined as:
...(i)
Where, a is the initial value and b is the growth factor.
First point from the given table is (1,10). It means, the equation (i) must be true for (1,10).
...(ii)
Second point from the given table is (2,20). It means, the equation (i) must be true for (2,20).
...(iii)
Dividing (iii) by (ii), we get
![\dfrac{20}{10}=\dfrac{a(b)^2}{ab}](https://tex.z-dn.net/?f=%5Cdfrac%7B20%7D%7B10%7D%3D%5Cdfrac%7Ba%28b%29%5E2%7D%7Bab%7D)
![2=b](https://tex.z-dn.net/?f=2%3Db)
Putting
in (ii), we get
![10=a(2)^1](https://tex.z-dn.net/?f=10%3Da%282%29%5E1)
![\dfrac{10}{2}=a](https://tex.z-dn.net/?f=%5Cdfrac%7B10%7D%7B2%7D%3Da)
![5=a](https://tex.z-dn.net/?f=5%3Da)
Putting
in (i), we get
![y=5(2)^x](https://tex.z-dn.net/?f=y%3D5%282%29%5Ex)
The required exponential function for the given table of values is
. So, the missing values are 2 and x, where 2 is in the base and x is in the power.
