Answer:
y = 15·2.1599^x
Step-by-step explanation:
We know that the number changed by the ratio 1523/15 = 101.5333... in 6 days, so the daily multiplier is the 6th root of this:
b = 101.5333...^(1/6) = 2.1599 . . . rounded to 4 dp
Of course, the coefficient 'a' in the equation is the initial number, 15.
Your exponential equation is ...
y = 15·2.1599^x
a = 15
b = 2.1599
7 1/2 * 2 = 15
The 3rd hour was 1/4 of the total distance in 3 hours.
1/4 = 0.25 as a decimal, and 25% as a percent.
15 (0.25) = 3.75
15 + 3.75 = 18.75
0.75 = 3/4 as a fraction.
So, he cycled 18 3/4 miles in 3 hours.
I hope this helps, and I am sorry if I get this question wrong. (which is in all likelihood)
Answer:
A.
Step-by-step explanation:
We have x in exponent, so it is an exponential function.
Exponent is negative, so is is an exponential decay.
