Answer:
The answer to your question is speed = 9 m/s
Step-by-step explanation:
Data
Winner Last runner
time = 45 s time = 48 s
speed = 9.6 m/s
Process
1) Calculate the distance they ran using the data of the winner
speed = distance / time
-Solve for distance
distance = speed x time
-Substitution
distance = (9.6)(45)
-Result
distance = 432 m
2.- Calculate the speed of the last runner
-Substitution
speed = 432/48
-Result
speed = 9 m/s
Answer: 9
Step-by-step explanation:
There are 8 equal sections which are meant to reflect the data Jasmine collected from surveying the students.
This means that each section represents;
= 36/8
= 4.5 students.
There are 2 sections that represent the number of students who said they would be traveling during the holiday break.
= 4.5 * 2
= 9 students
Please type this as 2(sin 2x)^2=2 <span>2sin^2 2x=2 is confusing.
Reducing this expression: (sin 2x)^2 = 1
Taking the sqrt of both sides, sin 2x = plus or minus 1
If sin 2x = 1, then 2x must be pi/2 or 3pi/2, and so x must be pi/4 or 3pi/4.
Now you do this for sin 2x = -1.</span>
Is it 100 because it just is done ya and 1000
Answer: 2900185 Joules
Step-by-step explanation:
Force used to tow the car is 1600N
Angle(α)= 25
Displacement = 2km
Recall that 1km= 1000m
Therefore 2km= 2000m
Workdone= FdCos α
W= 1600 * 2000 * cos 25
W=2900184.919
W= 2900185 Nm(when approximated to the nearest integer)
Since 1J = 1Nm
Work done = 2900185 J
