Answer:
2 hours
Step-by-step explanation:
monday = 6 hrs
tuesday = 4 hrs
6 - 4 = 2
2 hours
The answer to this would be 40 because you multiply 12x0.30 and get 40 which mean 12 is 30% of 40 total
The answer to 4x×3y-2 (x to the second power ×3) x=4 y=6
The answer is 35
Answer:
-2.5
I got -2.5 as slope because slope is equal to rise over run so that means
the equation would turn out as -29+9/15-7=-20/8
-20/8=-2 4/8,-2 1/2,1/2=0.5,so the answer turns into -2.5
Answer:the horizontal displacement is 34.64 meters
The maximum height is 15 meters
Step-by-step explanation:
As the ball moves from the ground at 30 degrees, it travels through a parabolic path. It can therefore be likened to a projectile. The horizontal displacement to where it lands is the range. The formula for determining range,R is
R = U^2Sin2#)/g
Where
U represents the initial velocity of the ball
g is acceleration due to gravity
# represents the angle above the horizontal.
From the information given
# = 30 degrees
U = 20 m/s
g = 10m/s^2
R = 20^2Sin2×30)/10 = (400Sin60)/20 = (400×0.8660)/10
= 34.64 meters
To determine the maximum height of the ball, H,
H = (U^2Sin^2#)/2g
H = (20^2 × Sin^2 30)/2×10
H = (400 × 0.866^2)/20 = 15 meters
