Answer:
<em>3 seconds</em>
Step-by-step explanation:
Complete question:
<em>An object is dropped from a bridge and allowed to freefall to the ground. The height of the object over time can be modeled using h(t)=144-16t2. How many seconds will it take the object to reach the ground? 2 seconds 3 seconds 9 seconds 16 seconds</em>
<em></em>
Given the height of an object modelled by the expression;
<em>h(t)=144-16t²</em>
The object will reach the ground when h(t) = 0
Substitute into the formula
0 = 144 - 16t²
-144 = -16t²
144 = 16t²
Swap
16t² = 144
t² = 144/16
t² = 9
Square root both sides
√t² = ±√9
t = ±3secs
<em>Since the time cannot be negative, hence the object will reach the ground 3 seconds after</em>

Step-by-step explanation:
<u><em>The complete question is</em></u>
On Saturday,1/8 of the people who visited were senior citizens,1/8 were infants,1/4 were children,and 1/2 were adults.How many of each group visited the zoo on Saturday? It's has to equal to 32,096 people
we know that
1/8 of people were senior citizen
1/8 were infants
1/4 were children
1/2 were adults
To find out how many of each group visited the zoo on Saturday, multiply the total of people by the fraction of each group
so
<u><em>Verify</em></u>
The sum of the total of each group must be equal to 32,096 people
so
