Answer:
50
Step-by-step explanation:
So you would have to set up a equation to find the length and width. The equation would be w+(w+2)=16
that simplifies to 2w+2=16
2w=14
w=7
the width is 7
the length is 9
Answer:
The stone will be in flight for 3 seconds
Step-by-step explanation:
Given the equation;
d = -16t^2 + vt + h
Where;
v = the initial velocity
h = the initial height
Given;
v = 48 ft/s
h = 0
Substituting into function d;
d = -16t^2 + 48t + 0
d = -16t^2 + 48t
At the point of launch and the point of landing d = 0.
We need to calculate the values of t for d to be equal to zero.
d = -16t^2 + 48t = 0
-16t^2 + 48t = 0
Factorising, we have;
16(-t+3)t = 0
So,
t = 0 or -t+3 = 0
t= 0 or t =3
Change in t is;
∆t = t2 - t1 = 3 - 0
∆t = 3 seconds.
The stone will be in flight for 3 seconds.
Answer:
Average = 16, standard deviation =
Step-by-step explanation:
15+12=27
27+(17+14)+22=27+31+22=80
80/5=16
Distance from 22 to 16=6, from 12 to 16=4, so deviation = 5
