Answer:

Step-by-step explanation:

The speed limit is about 11.2 meters per second. Usain is running 10.38 meters per second. So he is running slower than the speed limit.

100 m / 9.63 s = 10.38 m/s

He ran at about 10.38 m/s.

10.38 m/s = 37,368 m/hr

(40,234 m/hr) / (3600 s/hr) = 11.2 m/s

The speed limit is about 11.2 m/s.

His speed will be less than the speed limit.

1. A student invests $500 in a savings account that earns 4% interest per
bixtya [17]

Answer:

The equation can be used to determine the amount of money S(t)  that her savings account has after t years is S(t)=500(1.04)^t

Step-by-step explanation:

A student invests $500 in a savings account

Principal = $500

Rate of interest = 4% = 0.04

We are supposed to find equation can be used to determine the amount of money S(t)  that her savings account has after t years

Formula : A=P(1+r)^t

Where A is the amount after t years =S(t)

t = time

r = rate of interest in decimals =0.04

P = Principal=500

Substitute the value in the formula :

So, S(t)=500(1+0.04)^t

S(t)=500(1.04)^t

Hence The equation can be used to determine the amount of money S(t)  that her savings account has after t years is S(t)=500(1.04)^t

Unit rate of Kim => 9 miles in 12 minutes => 0.75 miles / minutes => 25 / 0.75 It will take 33.33 minutes for Kim to arrive Unit rate of Jay 10 miles in 15 minutes. => 10 miles /15 minutes => 0.67 miles /minute => 25 / 0.67 It will take Jay 37.31 minutes to arrive at the beach. SO Kim will arrive first
