This problem is a projectile problem. The initial velocity is 50m/s at an optimum angle of 45. The maximum height or the height of the y component is at it's highest is asked.
Informtion needed:
Acceleration due to gravity = 9.81m/s^2
Formula:
Hmax = ((V^2)(sin(angle))^2)/2g
Hmax = ((50^2)(sin45)^2)/(2*9.81) = 63.71 or letter B 63.5 m is the closest answer.
You have to remember that "percent" means "hundredths".
So '25%' means 0.25 .
50 percent means 0.50 .
77% means 0.77 .
etc.
To find 41% of a number, multiply the number by 0.41 .
Answer:
x = 1, y=3
Step-by-step explanation:
Answer:
x=8
Step-by-step explanation:
set the equations equal to themselves and solve
3x-9=2x-1
+9 and -2x
x=8
Check:
3(8)-9=2(8)-1
24-9=16-1
15=15
The answer is probably 1/12
