10. The height, h, in meters aboveground, of a projectile at any time, t, in seconds, after the launch is defined by the functio

RSB [31]

Answer:

Option B

The projectile reached a maximum height of 11.4 meters in 1.3 seconds and it was launched from 2.0 meters above the ground.

Step-by-step explanation:

$h(t) = −6t^{2} + 15t + 2$

Differentiating the above equation with respect to time t

h'=-12t+15

h'=0

12t=15

$t=\frac {15}{12}=1.25 s$

$h_{max}= −6t^{2} + 15t + 2= −6\times 1.25^{2} + 15\times 1.25 + 2=11.375 m\approx 11.4 m$

at t=0 then $h=−6\times 0^{2} + 15\times 0 + 2=2 m$

The population of City A in 2000 was 40 thousand people and the population increased by 13% each year. The function f determines

Fofino [41]

Answer:

f(x) = 40(1 + 0.13)^x

Step-by-step explanation:

The general formula for an exponential growth function is;

f(x) = a(1 + r)^x

Where;

a= initial population of the city

r= population growth rate

x = number of years

Given that;

a= 40,000

r= 0.13

The population of the city in thousands of people in terms of x is;

f(x) = 40(1 + 0.13)^x
