Answer:
m∠4:55°
Step-by-step explanation:
this is because 2 and 4 are congruent to each other
Answer:
The z score of the 65-mph speed limit is -0.75
Step-by-step explanation:
The z score is given by the relation;
Where:
Z = Normal (Standard) or z score
x = Observed speed score
μ = Mean, expected speed
σ = Standard deviation
Where we plug in the values for x = 65-mph, σ = 8 mph and μ = 71 mph, into the z-score equation, we get;
Hence the z score of the 65-mph speed limit =-3/4 or -0.75.
15/9 = 1.66 = 1.7 so, technically 2 vans will need to be rented.
Line BD is perpendicular to line AC. both angles ADB and CDB are right angles.
4x+10=90
subtract 10 from both sides
4x=80
divide both sides by 4 to isolate x
x=20
plug in 20 for x in the equation (x+11) to find the measure of angle c
20+11=31°
the measure if angle c is 30°
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.
