Step-by-step explanation:
(2, m) => (n, 5) => (10, 2)
We have 2n = 2 + 10 and 2(5) = m + 2
Hence n = 6 and m = 8.
You are a kite sailing across the ocean. The table gives your height at different times.
A. How many feet do you move each second?
Answer: From the given table information, we clearly see that after every second the kite moves 2 feet
B. What is your speed? Give the units.
Answer: We know that :
Therefore, the speed of the kite is 2 feet per second
C. Is your velocity positive or negative?
Answer: The velocity is positive, because the height of the kite goes on increasing direction
D. What is your velocity? Give the units.
Answer: Here the velocity of kite is:
feet per second
Answer:
The initial weight of the bar soap is 123g
Step-by-step explanation:
No options but the question can still be solved.
Given
Required
What does the y intercept mean
Start by calculating the y intercept (i.e. when x = 0)
The equation becomes
This means that the initial weight of the bar soap is 123g
