Answer:
1: (0,-4)
2:-2x-4
Step-by-step explanation:
™The y-intercept refers to the value where the graph cuts the vertical line.
4 x + 30 = 5x + 20
-5x -5x
-x + 30 = 20
-30 -30
- x = -10
x = 10
Answer:
-5
Step-by-step explanation:
The y-coordinate of the bottom of the curve is -5. This is the minimum value of the function. There are no function values lower than this.
We can find the height of the altitude by the ratio of sin. See my attachment.
sin of angle = side in front of the angle / hypotenuse
sin x = height/distance
If the two pilot is rising in an hour, then the first distance is 400 miles, the second distance is 300 miles.
Find the height of first pilotheight/distance = sin x
height/400 = sin 30°
height = sin 30° × 400
height = 1/2 × 400
height = 200
Find the height of second pilotheight/distance = sin x
height/300 = sin 40°
height = sin 40° × 300
height = 0.642 × 300
height = 192
So the first pilot traveling 400 mph with 30° is more quickly to reach high altitude than the second pilot traveling 300 mph with 40°
