Answer:
0.9043secs and 0.3456secs
Step-by-step explanation:
Given the height of an overhand volleyball modeled as h=-16t^2+20t+6.
If the height is 11feet, then;
11 = -16t^2+20t+6.
-16t^2+20t+6 - 11 = 0
-16t^2+20t-5 = 0
Multiply thriugh by -1
16t^2-20t+5 = 0
Factorize
t = 20±√20²-4(16)(5)/2(16)
t = 20 ±√400-320/32
t = 20 ±√80/32
t = 20 ±4√5/32
t = 20±8.94/32
t = 28.94/32 and 11.06/32
t = 0.9043 and 0.3456
Hence the required time are 0.9043secs and 0.3456secs

Step-by-step explanation:
5 is completely irrelevant, Vertical angles are congruent.
The explicit formula of the function d(n) is 
<h3>How to determine the explicit formula?</h3>
The function is given as:
d(1) = 2.7
d(n) = d(n-1) x (6.1)
The above means that the function is an exponential function, and it has the following parameters:
First term, d(1) = 2.7
Common ratio, r = 6.1
The explicit formula of an exponential function is:
So, we have
Hence, the explicit formula of d(n) is

Answer:
what
Step-by-step explanation:
Answer:
Domain is the x and the range is the y, that being said, 1) domain: 1,3,5 range: 2,4,6
2) you need to solve for x then plug x in and solve for y when solving for x you can plug in a number like 1
3) same circumstance as number 2!
