A cyclist travels 2/3 of his journey at the average speed of 12 miles per hour. He then travels the remaining 30 miles of his jo

natita [175]

If the cyclist traveled 2/3 of his journey already, then the remainder would be 1/3 of his journey, which we know is 30 miles. Double that and we have the miles he traveled during the first 2/3, 60. Then divide 60 by the miles per hour, 12, to get 5 hours. Add in the 3 hours from the remaining 1/3 of the journey and you have your total; the cyclist's trip took 8 hours.

Place the steps for finding f -1(x) f(x)=2x+5

olya-2409 [2.1K]

Answer:

$f^{-1}(x) = \frac{x-5}{2}$

Step-by-step explanation:

$f(x) = 2x+5$

Step 1) Replace y = f(x)

$y = 2x+5$

Step 2) Exchange x and y

$x =2y+5$

Step 3) Solve for y

$x =2y+5$

Subtracting both sides by -5

$x - 5= 2y$

$2y = x-5$

Dividing both sides by 2

$y = \frac{x-5}{2}$

Step 4) Replace $y = f^{-1}(x)$

$f^{-1}(x) = \frac{x-5}{2}$

EGG DROP The physics class is holding an egg drop competition. The formula h= −16t2+h0 can be used to approximate the number of

WITCHER [35]

By solving a quadratic equation we will see that the egg will hit the ground after 1.58 seconds.

<h3>How long will take the egg to reach the ground?</h3>

Here we know that the initial height of the egg is 40ft, so the equation for the height will be:

$h(t) = -16*t^2 + 40$

The egg will hit the ground when h(t) = 0, so we need to solve the quadratic equation:

$h(t) = -16*t^2 + 40 = 0\\\\16t^2 = 40\\\\t^2 = 40/16\\\\t = \sqrt{40/16} = 1.58$

This means that the egg will hit the ground after 1.58 seconds.
