In this question all required information's are already provided. Based on these details the answer to the question can be easily determined. Let us now write down all the information's that are already given.
Mass of the roller coaster = 1000 kg
Velocity of the roller coaster = 20.0 m/s
We know the formula for finding the kinetic energy is
Kinetic energy = 0.5 * mass * (velocity) ^2
= 0.5 * 1000 * (20)^2
= 0.5 * 1000 * 400
= 200000 Joules
So the Kinetic energy of the roller coaster is 200000 joules.
Answer:
Angle k = 14°,L = 70° and N = 96°
Step-by-step explanation:
According to the question,Enzo drew Triangle K L N. In Enzo’s triangle, Measure of angle K is represented as x degrees. The measure of Angle L is 5 times Measure of angle K. The measure of Angle N is 16 degrees less than 8 times Measure of angle K.
From here,we know that angles in a triangle sum up to 180°
If angle k = x
Angle L = 5x
And angle N = 8x - 16
Sum of a all three is equal to 180°
(8x - 16) + x + 5x = 180
14x -16 = 180
X = 196/14
X= 14.
Therefore,angles k = 14°, L = 70° and N= 96°
Let's now assume that the question was to find the angles k,l and n which is already written above and to pick the correct statement relating to the question.
My statement here is( since we weren't given the complete question) that the triangle is a scalene triangle
The answer is 20.5 feet, because when you draw out the triangle and label the angles and given sides and then use the law of sines, you end up with it.
It’s Number A have a nice day
Answer:
A. Statistic
Step-by-step explanation:
Usually whole population is difficult to cover so the part of population is considered to assess the aspects of population. The statistic is the quantity which summarizes the sample. The problem illustrate that summary measure is calculated from sample to describe a population. As the summary measure is computed from sample then it is a statistic.
