Answer: I think the answer is 38.
Step-by-step explanation:
Answer:
The formula for exponential growth is f(x)=a(1+r)^x, where a is the initial amount/number, r is the growth rate, and x is the number of years/month/etc. The problem tells us that the initial area is 4500. Every year, it decreases by 7.25%, which is technically -0.0725. "t" is the time. Therefore, we plug in those values into the formula. Then, we have:
f(x) = 4500(1-0.0725)^t
f(x) = 4500(0.9275)^t.
Answer:
x =8/9 i dont know if im correct
The speed of Sali is 18.75 km/hr.
Given,
Total distance travelled by Jane and Sali =63 km.
The total time is taken by Jane=3.5 hours.
Sali started to cycle 4 minutes after Jane started to cycle
hours.
<h3>What is the formula to find speed?</h3>
The formula to find speed is
.
The speed of Jane
.
Let the speed of Sali be
.
Sali caught up with Jane when they had both cycled 30 km.
Thus, 





Therefore, the speed of Sali is 18.75 km/hr.
