12
Step-by-step explanation:
Answer:
Slope is Zero 0
Step-by-step explanation:
this is because the line is horizontal and therefore has no slope
Answer:
7/8 of a cake
Step-by-step explanation:
4 4/4 - 3 1/4 = 1 3/4
7/4 x 1/2 = 7/8
I^32 = (i^4)^8 and i^4 = 1
so (i^4)^8 =1^8 = 1
The trick on all questions like this is to get as many i^4’s out of the way, since they’re all just 1s.
<span>Before all let's just convert Km/s into m/s :
2.41 km/s = 2410m/s\
To solve the second part
First we have to find Vy
Vy = 2410 m/s * sin 61.5
= 2410 m/s * 0.8788
=2117.908 m/s.
When the shell reaches it's maximum height the vertical velocity component will be zero
based on that theorem let's apply linear motion equation
V = u + at
0 = 2117.908 m/s - 9.8 m/S^2 * (t)
t = 216.1130 s
As the shell has to go upward and comes back to earth the shell will require a same amount of time in order to reach earth again so the total time that shell will spend on the air will be
<span>2*t
= 432.226 s
I hope my answer has come to your help. Have a nice day ahead and may God bless you always!</span></span>
