the number of hours h that it takes for ice to malt varies inversely with the temperature t it takes 3hours for a piece of ice t

Reptile [31]

Answer:

Step-by-step explanation:

Formula

h = k/temp

Givens

h = 4 hours

t = 45 degrees

Solution

3 = k / 45 Multiply both sides by 45

3*45 = k

k = 135

Problem

what happens when h = 4 hours?

h = 4

k = 135

temp = ?

4 = 135 / temp Multiply both sides by temp

4temp = 135 Divide by 4

temp = 135 / 4

temp = 33.75

Note that as the time went up, the temperature came down

SOLUTION: a diver jumps from a diving board that is 24 feet above the water. the height of the diver is given by h= -16(t-1.5)(t

lara [203]

Answer:

The diver will hit the water at 1.5 seconds

Step-by-step explanation:

Given

$h= -16(t-1.5)(t+1)$

Required (Missing from the question)

When will the diver hit the water?

To do this, we simply solve for t

When the diver hits the water, the height is 0 (at that point)

So, substitute 0 for h in $h= -16(t-1.5)(t+1)$

$0= -16(t-1.5)(t+1)$

Divide both sides by -16

$\frac{0}{-16} =\frac{-16(t-1.5)(t+1)}{-16}$

$\frac{0}{-16} =(t-1.5)(t+1)$

$0 =(t-1.5)(t+1)$

$(t-1.5)(t+1)=0$

Split

$t - 1.5 = 0$ or $t + 1 = 0$

Solve for t

$t = 1.5$ or $t = -1$

But time (t) can not be negative.

So:

$t = 1.5$

Hence, the diver will hit the water at 1.5 seconds
