Answer:
y=21
Step-by-step explanation:
y= 9 cos x =3 so y=3 when x=1 on the base level so if x=7 would be x=1 on the base level * 7 then y=3 on the base level * 7 would be y = 21
Answer: The number of movies Abdul watches each month if he watches two per month is:
Number of movies = n

Answer:
Distance between the observer and the red car is
Step-by-step explanation:
Diameter of field = 500 m
Radius of field =
Let R be the radius and the speed at which the car completes race be w
So,
Car finished 5 laps in minutes = 30
Car finished 1 lap in minutes =
So,
Refer the attached figure
Angle between car and observer = wt
So, Distance between the observer and the red car is give as A sin wt
So, Distance between the observer and the red car=
Answer:
6y^2√10 +12y √5
Step-by-step explanation:
3√10(y^2√4 + √8y)
Distribute
3√10(y^2√4) +3√10 (√8y)
3y^2 √40+3y√80
We know that √ab = √a√b
3y^2 √4*√10+3y√16√5
3y^2 *2*√10+3y*4√5
6y^2√10 +12y √5
