Answer:
t = 5 seconds
Step-by-step explanation:
It is given that, the height h, in feet of a ball above the ground is given by :

Where t is in seconds
We need to find how long does it take the ball to hit the ground? When it hits the ground, its height will be equal to 0. So,

Neglecting negative time.
It means ball will take 5 seconds to hit the ground.
Answer:
population will be 79806.
Step-by-step explanation:
Population of a town 4 years ago was 50,000
Population of town had grown exponentially and present population is 63,124.
So the formula of the population growth will be

Where
= Final population n = number of years.
= Initial population
r = rate of increase in population per year.
so 63124 = 50,000 


= 1.0813
Now we have to find the population after 4 years from now.
= 
= 
= 63124 × 1.264
= 79806
Therefore, after 4 years from now population will be 79806.
Answer:16/25
Step-by-step explanation:
0.64=64/100=16/25
Answer:
120
Step-by-step explanation:
since 26 is the longest side, it would be the hypotenus and we can exclude it.
the equation for the area of a triangle is basexheight/2.
our base or height must be the other two sides
10x24=240
240/2=120
so 120 would be ur answer
base times length times height
