I would say neither of the above.
A is incorrect because in the graph, the curves get shorter over time, and if you were riding the same Ferris wheel, the curves would be the same size the whole time, because the Ferris Wheel would stay the same shape and height.
B is incorrect because the height increases then decreases and increases and decreases, etc, while the description is simply, a descending paper plane.
C is incorrect because it wouldn't be both of the above since they were both wrong.
Answer:
The two lines are not perpendicular because the product of their slopes is not equal to -1
Step-by-step explanation:
The product of the slopes of the perpendicular line is -1
- That means one of them is and additive and multiplicative inverse of the other
- If the slope of one of them is m, then reciprocal m and change its sign, then the slope of the perpendicular is
- The formula of the slope is

Let us find from the graph two points lie on each line and calculate the slopes of them and then find its product if the product is -1, then the two lines are perpendicular
From the graph
∵ The red line passes through points (4 , 0) and (0 , 8)
∴
= 4 and
= 0
∴
= 0 and
= 8
∵ 
∴ The slope of the red line is -2
∵ The blue line passes through points (5 , 5) and (0 , -5)
∴
= 5 and
= 0
∴
= 5 and
= -5
∵ 
∴ The slope of the blue line is 2
∵ The products of the slopes of the two lines = -2 × 2 = -4
∴ The product of the slopes of the lines not equal -1
∴ The two lines are not perpendicular
Answer:
7
Step-by-step explanation: 5.5 divided by 0.75 is 7.3333333333
Find the difference in the two numbers you're comparing and then divide that number by the original number and multiply by 100. it should give you the percentage of the value im not sure how to add the years in there.
