Answer:
4. j(11) = 8
I think it is linear
5. g(-3) = 18
No, it's a parabola since x is to the second power
6. f(-7) = 5
No, I think it's an absolute value function
7. h(0) = 13
I think it is linear, just the slope is 0
Step-by-step explanation:
-------
Ans: (x/(3/4)) mph = (4x/3)mph = (4/3)x mph
------------------------
1. If you have 1 first then... 1,2,3,4 - 1,3,2,4 - 1,2,4,3 - 1,3,4,2 - 1,4,3,2 - 1,4,2,3
2. If you have 2 first the.... 2,1,3,4,- 2,1,4,3 - 2,3,1,4 - 2,3,4,1 - 2,4,3,1- 2,4,1,3
3. And so one with 3,4
Hope this helps:)
Let α represent the acute angle between the horizontal and the straight line from the plane to the station. If the 4-mile measure is the straight-line distance from the plane to the station, then
sin(α) = 3/4
and
cos(α) = √(1 - (3/4)²) = (√7)/4
The distance from the station to the plane is increasing at a rate that is the plane's speed multiplied by the cosine of the angle α. Hence the plane–station distance is increasing at the rate of
(440 mph)×(√7)/4 ≈ 291 mph
