Answer:
Step-by-step explanation:
y=ar^x
(ar^5)/(ar^3)=72/432
r^2=1/6
Since r^2 < 1
This is exponential decay.
Answer: =125.6
Step-by-step explanation:
Add 26.5 to both sides of the equation
Simplify
Answer:
F. 6s > 4s +8
Step-by-step explanation:
From a reference point at the beginning of the track, Ward's car will be located 4s+8 feet down the track after s seconds. That is, it starts 8 feet down the track, and increases its distance by 4 feet every second.
From the same reference point, Heskey's car will be located 6s feet down the track after s seconds. Its distance starts from zero and is increasing at the rate of 6 feet every second.
For Heskey's distance to exceed Ward's distance you want ...
6s > 4s +8 . . . . . . matches choice F
4.022 is greater. Hope it helps
