Answer:
2.45 gallons of gasoline were in the tank before.
Step-by-step explanation:
Consider the provided information.
The tank can hold gallons of gasoline when completely full. He had some gas in the tank and added 10.3 gallons of gasoline to fill it completely.
We need to find: How many gallons of gasoline were in the tank before Javier added some?
For this, we need to subtract added gallons of gasoline from the capacity of the tank.
Hence, 2.45 gallons of gasoline were in the tank before.
The exponential function which represented by the values in the table is ⇒ 3rd answer
Step-by-step explanation:
The form of the exponential function is , where
- a is the initial value (when x = 0)
- b is the growth/decay factor
- If k > 1, then it is a growth factor
- If 0 < k < 1, then it is a decay factor
The table:
→ x : f(x)
→ -2 : 16
→ -1 : 8
→ 0 : 4
→ 1 : 2
→ 2 : 1
∵
- To find the exponential function substitute the value of x and f(x)
by some values from the table to find a and b, at first use the
point (0 , 4) to find the value of a
∵ x = 0 and f(x) = 4
∴
- Remember that any number to the power of zero equal 1
except the zero
∵
∴ 4 = a(1)
∴ a = 4
Substitute the value of a in the equation
∴
- Chose any other point fro the table to find b, lets take (1 , 2)
∵ x = 1 and f(x) = 2
∴
∴ 2 = 4 b
- Divide both sides by 4
∴
- Substitute the value of b in the equation
∴
The exponential function which represented by the values in the table is
