The earning of Lin per year is $ 42,540 .
Step-by-step explanation:
Given as :
The total earning of James and Lin together = $ 81,980 per year
The earning of Lin is $ 3100 more per year than James
Let The earning of James = $ J
And The earning of Lin = $ J + $ 3100
So, According to question
The total earning of James and Lin together = $ 81,980 per year
Or, The earning of Lin + The earning of James = $ 81,980 per year
Or, $ J + $ 3100 + $ J = $ 81,980 per year
or, 2 $ J = $ 81,980 - $ 3100
Or, 2 $ J = $ 78880
∴ J =
I.e The earning to James per year = $ 39,440
And The earning of Lin per year = $ 34,440 + $ 3100 = $ 42,540
Hence, The earning to James per year is $ 39,440
And The earning of Lin per year is $ 42,540 . answer
Answer:
16 seconds (Approximately)
Step-by-step explanation:
Given:
The function that gives the distance of snowboarder from the bottom of hill with time 'x' is:
Final position of the snowboarder is
Now, plugging in 100 for 'd' and solving for 'x', we get:
Adding -1100 both sides, we get:
Dividing both sides by -4, we get:
Taking square root and neglecting the negative root as time can't be negative. So,
Therefore, after 16 seconds, the snowboarder will be at a distance of 100 ft from bottom of hill.
