Answer:

Step-by-step explanation:

During the breaststroke competitions of a recent olympics, Nelson diebel swam 100 meters in 62 seconds, this means that his unit rate would be 100/62 = 1.61 meters per second.

Mike bower man swam 200 meters in 130 seconds. This means that his unit rate would be 200/130 = 1.54 meters per second. The rate of 1.61 meters per second is higher than the rate of 1.54 meters per second. Therefore, Nelson diebel swam at a faster rate.

Answer:

The expression that represents the number of deer in the forest is

y(x) = 50*(1.013)^x

Step-by-step explanation:

Assuming that the number of deer is "y" and the number of months is "x", then after the first month the number of deer is:

y(1) = 50*(1+ 0.15/12) = 50*(1.0125) = 50.625

y(2) = y(1)*(1.0125) = y(0)*(1.0125)² =51.258

y(3) = y(2)*(1.0125) = y(0)*(1.0125)³ = 51.898

This keeps going as the time goes on, so we can model this growth with the equation:

y(x) = 50*(1 - 0.15/12)^(x)

y(x) = 50*(1.013)^x

2x+3y=41 and 5x+4y=85
Sever21 [200]

Answer:

5x+4y=85-

 Slope = -2.500/2.000 = -1.250

 x-intercept = 85/5 = 17

 y-intercept = 85/4 = 21.25000

2x+3y=41-

 Slope = -1.333/2.000 = -0.667

 x-intercept = 41/2 = 20.50000

 y-intercept = 41/3 = 13.66667
