April shoots an arrow upward at a speed of 80 ft/sec from a platform of 25 ft. High. The pathway of the arrow can be represented

soldi70 [24.7K]

Answer:

125feet

Step-by-step explanation:

Given the equation that modeled the height expressed as h = -16t^2 + 80t + 25, where h is the height and t is the time in seconds.

The arrow reaches the maximum height at dh/dt = 0

dh/dt = -32t + 80

0= -32t+80

32t = 80

t = 80/32

t = 2.5secs

substitute t = 2.5 into the formula;

h = -16t^2 + 80t + 25

h = -16(2.5)^2 + 80(2.5) + 25

h = -16(6.25)+225

h = -100+225

h = 125

Hence the maximum height the arrow reaches is 125feet

During the calendar year of 1971 a total of 171 deaths were caused by influenza in a city of 450,000 persons. The temporal distr

masha68 [24]

Answer and Step-by-step explanation:

The computation of annual and quarterly mortality rates per 100,000 population is shown below:-

Quarterly mortality rates are

$= \frac{Deaths}{Population\ in\ the\ city}\times Population$

For the first quarter

$= \frac{54}{450,000}\times 100,000$

= 12 death per 100,000 population

For the second quarter

$= \frac{43}{450,000}\times 100,000$

= 9.5 death per 100,000 population

For the third quarter

$= \frac{35}{450,000}\times 100,000$

= 7.7 death per 100,000 population

For the fourth quarter

$= \frac{39}{450,000}\times 100,000$

= 8.6 death per 100,000 population

Now the annual mortality is

$= \frac{Deaths}{Population\ in\ the\ city}\times Population$

$= \frac{171}{450,000}\times 100,000$

= 38 death per 100,000 population
