scoray [572]

Answer:

5/6

Step-by-step explanation:

1/3 + 1/2 is a simple addition fraction problem.

You'd find the LCM (lowest common denominator) which is 6. First, we'll take 1/3 which the denominator becomes 6. You see one side has been basically multiplied by 2, so you'd do it to both sides, giving us 2/6. Next, we do the same thing with 1/2. 2 -> 6 1 -> 3. 3/6. So finally, we have 3/6 + 2/6, which is 5/6.

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
