An object is dropped from a bridge and allowed to freefall to the ground. The height of the object over time can be modeled usin
ioda
The height at time t is
h(t) = 144 - 16t²

When t = 0, then h = 144.
Therefore the height from the ground is 144 when the object is dropped.

When the object reaches the ground, h = 0.
Therefore
144 - 16t² = 0
t² = 144/16 = 9
t = 3 s

Answer:
The object reaches the ground in 3 seconds.

Explain how to compute 3/4 x 4/5 using one diagram.
Drupady [299]

Answer:

The simplified form of given expression is 3/5.

Step-by-step explanation:

The given expression is

\frac{3}{4}\times \frac{4}{5}

We need to find the product of two factions using diagram.

For 3/4, draw a box and divide it in 4 equal parts by using vertical lines. The  color three parts of it.

For 4/5, draw a box and divide it in 5 equal parts by using horizontal lines. Then color the four parts of it.

Now combined both boxes and shown below.

From the below figure it is clear that

The number of common shaded small boxes =  12

Total number of small boxes = 20

The required fraction is

Fraction=\frac{\text{Number of common shaded small boxes}}{\text{Total number of small boxes}}

Fraction=\frac{12}{20}

Cancel out common factor.

Fraction=\frac{3}{5}

Therefore, the simplified form of given expression is 3/5.
