Answer:
-4 seconds
Step-by-step explanation:
The question says he lost 8 seconds off the leader for each of the 3 pit stops that he made
8 x 3 = 24
This means that 24 seconds was lost.
If 10 seconds were gained for the next 2 pit stops, the driver gained a total of
2 x 10 = 20seconds
The amount of time he is off leader =
20 -24
= -4 seconds
We have it that -4 seconds represents time he is off the leader.
Thank you!
The exponential function that passes through (0,2) and (3,54) is a growth function
The exponetial function is y = 2 * 3^x
<h3>How to construct the exponential function?</h3>
The points are given as:
(x,y) = (0,2) and (3,54)
An exponential function is represented as:
y = ab^x
Substitute the points in the equation
2 = ab^0 and 54 = ab^3
Solve 2 = ab^0
a = 2
Substitute 2 for a in 54 = ab^3
54 = 2b^3
Divide by 2
27 = b^3
Take the cube roots of both sides
b = 3
So, we have:
y = ab^x
This becomes
y = 2 * 3^x
Hence, the exponetial function is y = 2 * 3^x
