The question is incomplete, the complete question is;
Chelsea dropped a bouncy ball off the roof while Nery recorded its rebound height. The table shows their data. Note that the 0 in the "Bounce " column represents the starting height. To what family does the function belong? Explain how you know. b. Show the data as a sequence. Is the sequence arithmetic, geometric, quadratic, or something else? Justify your answer.
Bounce Rebound Height 0 800 cm 1 475 cm 2 290 cm 3 175 cm 4 100 cm 5 60 cm
Answer:
exponential
Geometric
Step-by-step explanation:
We have to test the data to know where it falls in. Let us just take three data points for our test.
To test if it is AP;
475 - 800 = -325
290 - 475 = 185
It is not an AP
Let us test if it is exponential with three data points
475/800 = 0.6
290/475 = 0.6
It is exponential hence we can write;
t(n) = 800(0.6)^n-1
Since a common difference that can always be approximated to 0.6 is obtained throughout, the sequence is geometric.
Answer: inverse
Step-by-step explanation: inverse is the relationship between the variables in the table a direct variation.
Answer:
x=12
Step-by-step explanation:
Distribute:
3x - 3 = 2x + 9
Combine like terms to one side:
x = 12
Answer:
The distance you are from the base of plateau = 
Step-by-step explanation:
Given:
Height of plateau = 70 m
Angle of elevation to the top of plateau = 35°
To find the distance you are from the base of plateau.
We will construct a triangle ABC to model the given situation. The triangle would be a right triangle for which we know an angle and its opposite side. We need to find the adjacent side of the triangle.
We will apply trigonometric ratio to find the adjacent side.
where 
represents the angle of reference.
Plugging in the values from the triangle.
Multiplying both sides by AC.
Dividing both sides by 
∴ 
The distance you are from the base of plateau =
Answer:
Yes
Step-by-step explanation:
They both equal 50%
