Simplified radical form of 4800 feet how many seconds was the diver in a free fall? Using functions (t)=16t^2 models the distanc

amm1812

Answer:

The diver will be in free fall for $10\sqrt{3}$ seconds.

Step-by-step explanation:

The distance in feet, that an object falls in t seconds is given by the function $h(t) = 16t^{2}$ .

Now, given that the height is 4800 feet and we have to calculate the number of seconds the diver was in a free fall.

Therefore, $4800 = 16t^{2}$

⇒ $t^{2} = \frac{4800}{16} = 300$

⇒ $t = \sqrt{300} = \sqrt{100 \times 3} = 10\sqrt{3}$ seconds.

Therefore, the diver will be in free fall for $10\sqrt{3}$ seconds. (Answer)

Sarah plants 760 vines in rows containing either 20 vines or 25 vines. There are 3 times as many rows containing 25 vines as the

bogdanovich [222]

Answer: 27 rows contain 25 vines.

Step-by-step explanation:

Let x represent the number of rows that contain 20 vines.

Let y represent the number of rows that contain 25 vines.

Sarah plants 760 vines in rows containing either 20 vines or 25 vines. This means that

20x + 25y = 760- - - - - - - - - - -1

There are 3 times as many rows containing 25 vines as there are rows containing 20 vines. This means that

y = 3x

Substituting y = 3x into equation 1, it becomes

20x + 25 × 3x = 760

20x + 75x = 760

95x = 760

x = 760/95

x = 9

y = 3x = 3 × 9

y = 27

Maddie's bedroom is rectangular. The length of one wall of Maddie's bedroom is 4 meters. The length from one corner of the bedro

salantis [7]

Answer:

The length of other wall is 3 meters.

Step-by-step explanation:

Given that:

Length of one wall = 4 meters

Length of diagonal from one corner to opposite corner = 5 meters

As the room is rectangular, the diagonal will form a right angled triangle.

The diagonal will be the hypotenuse.

Using pythagorean theorem;

$a^2+b^2=c^2$

Here,

a = 4 and c = 5

$(4)^2+b^2=(5)^2\\16+b^2=25\\b^2=25-16\\b^2=9$

Taking square root on both sides

$\sqrt{b^2}=\sqrt{9}$

b = 3 meters

Hence,

The length of other wall is 3 meters.
