Answer:

8km

Step-by-step explanation:

Given parameters:

Distance covered during the first 5hours  = 20km

Time taken to cover this distance  = 5hours

  Since ;

              Speed  = \frac{distance}{time}

               Speed  = \frac{20}{5}   = 4km/hr

Given also that the car traveled with a constant speed throughout the tour and we have found the speed to be 4km/hr;

            Distance covered in 2hrs;

                Distance  = speed x time

                                  = 4 x 2

                                    = 8km

8 km

Step-by-step explanation:

We begin by finding the speed of the tour boat;

Speed = distance/ time

= 20 / 5

= 4km/hr

To find distance traveled by the boat in 2 hrs;

Distance = speed * time

= 4 * 2

= 8 km

Answer:

We get t= 7.22 and t=0.28

The correct options are Option A and Option G

Step-by-step explanation:

The height h of toy rocket at time t seconds after  launch is given by the equation h(t) = -16t^2 + 120t + 8

We need to find how many seconds  until the rocket is 40 feet?

We are given height of rocket h(t) = 40 feet

and we need to find time t

Using the equation h(t) = -16t^2 + 120t + 8 we can find time t

We have h(t)=40

h(t) = -16t^2 + 120t + 8\\Put\:h(t)=40\\40= -16t^2 + 120t + 8\\16t^2-120t-8+40=0\\16t^2-120t+32=0

Now, we will solve the quadratic equation using quadratic formula: t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

We have a =16, b=-120 and c=32

Putting values and finding t

t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\t=\frac{-(-120)\pm\sqrt{(-120)^2-4(16)(32)}}{2(16)}\\t=\frac{120\pm\sqrt{14400-2048}}{32}\\t=\frac{120\pm\sqrt{12352}}{32}\\t=\frac{120\pm111.12}{32}\\t=\frac{120+111.12}{32}, t=\frac{120-111.12}{32}\\t=7.22\:,\:t=0.28

So, we get t= 7.22 and t=0.28

The correct options are Option A and Option G

Which of the following is a function equivalent to f(x) = 3(1.7)4x?
Molodets [167]
If you would like to find a function which is equivalent to f(x) = 3(1.7)4x, you can do this using the following steps:

<span>f(x) = 3(1.7)4x = 3(1.7)^(4x) = 3(1.7^4)^x = 3(8.35)^x = 3(8.35)x
</span>
The correct result would be B <span>f(x) = 3(8.35)x.</span>
