The cost y to rent an off road vehicle is proportional to the time that you rent it. It costs $48 to rent it for 3 hours. Write

Flura [38]

y = 16h is the equation that represents the situation, where "y" is the total cost to rent and "h" is the number of hours

<h3>Solution:</h3>

Given that, cost y to rent an off road vehicle is proportional to the time that you rent it

Let "y" be the cost to rent the road vehicle

Let "h" be the number of hours rented for

Then, by given statement,

$\text{ cost to rent the vehicle } \propto \text{ number of hours rented for }$

$y \propto h\\\\y = kh$ -------- eqn 1

Where "k" is the constant of proportionality

Given that it costs $ 48 to rent it for 3 hours

Therefore, y = 48 and h = 3

$48 = k \times 3\\\\k = \frac{48}{3} = 16$

Substitute k = 16 in eqn 1

$y = 16 \times h\\\\y = 16h$

Thus y = 16h is the equation that represents the situation

Find the equation of the exponential function represented by the table below:

Klio2033 [76]

Answer:

$y =5(3)^x$

Step-by-step explanation:

Given

The attached table

Required

Determine the equation of the table

The table represents an exponential function. So, we make use of

$y = ab^x$

When x = 0, y= 5.

So:

$y = ab^x$ becomes

$5 = ab^0$

$5 = a*1$

$5 = a$

$a = 5$

When x = 1; y = 15

So;

$y = ab^x$ becomes

$15 = a * b^1$

$15 = a * b$

Substitute 5 for a

$15 = 5 * b$

Divide both sides by 5

$\frac{15}{5} = \frac{5 * b}{5}$

$3 = b$

$b = 3$

Substitute values for a and b in: $y = ab^x$

$y =5(3)^x$

A ball rolls down an inclined plane such that the distance (in centimeters) that it rolls in t seconds is given by s(t) = 2t^3 +

IRISSAK [1]

The ball's velocity will be represented by the derivative of its distance function:

$s'(t)=6t^2+6t$

Now find the times $t$ for which this is equal to 30, i.e. solve

$6t^2+6t=30\implies t^2+t-5=0$

This has two solutions, $t=-\dfrac{1\pm\sqrt{21}}2$ , but only one is positive and falls in the interval $[0,3]$ . So the velocity reaches 30 cm/s when $t=-\dfrac{1-\sqrt{21}}2\approx1.79$ .

How many miles you can cover in 65 minutes

slega [8]

It depends on what type of transportation you would be using. If you were walking, it would be reeeaaaalllly slooowww. If a train, much faster!
