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

A money box contains only 10-cent and 20-cent coins. There are 34 coins with a total value of $5.40. How many coins of each

kow [346]

10x+20y=540
x+y=34
y=34-x

Plug in (34-x) for y:
10x+20(34-x)=540
10x+680-20x=540
-10x=-140
10x=140
x=14

There were 14 ten cent coins and 20 20 cent coins

In the interval 0 degrees < x < 360 degrees, find the values of x for which tan x = 2.7475. Give your answers to the neare

LuckyWell [14K]

Answer:

<em>Thus, the values of x are 70° and 250°</em>

Step-by-step explanation:

<u>Trigonometric Functions</u>

The tangent is defined as:

$\displaystyle \tan\theta=\frac{\sin\theta}{\cos\theta}$

Given a value for the tangent, there are two angles with the same tangent, one of them being $\theta$ and the other $\theta$ +180°.

We are given:

$\tan x=2.7475$

The angle is the inverse tangent:

$x=arctan (2.7475)$

Using a scientific calculator, we find the first angle:

x=70°

The second angle is found adding 180°:

x=70°+180°=250°

Thus, the values of x are 70° and 250°
