kolbaska11 [484]

Answer:

Step-by-step explanation:

A motorcycle has an initial speed of u m/s. It accelerates to a speed of 1.2u in 10 seconds

V = U + at

1.2u  = u  + a*10

=> a = 0.02u

S= ut + (1/2)at²

Distance in 1st 10 secs

S = u(10) + (1/2)(0.02)(10)²

=> S = 10u + u

=>  S = 11u  m

Constant speed 1.2u for 15 secs

S = 1.2u * 15

=> S = 18u m

Total Distance Covered d  = 11u + 18u = 29u  m

The growth of a species of fish in a lake can be modeled by the function ƒ(x) = 500(1.10)x, where x is time in months since Janu
Lyrx [107]

Answer:

f(x) = 500(1.1)^x

And we want to know what repreent the value 500 for this equation. If we see the general expression for an exponential function we have:

y= ab^x

Where a is the constant or the initial amount, b te base and x the independnet variable (time)

For this special  case we know that:

a = 500, b =1.1

And 500 represent the constant or initial value for the function

Step-by-step explanation:

We have the following function given:

f(x) = 500(1.1)^x

And we want to know what repreent the value 500 for this equation. If we see the general expression for an exponential function we have:

y= ab^x

Where a is the constant or the initial amount, b te base and x the independnet variable (time)
