Answer:
The x-intercept is 2.
The y-intercept is 5.
Step-by-step explanation:
The x-intercept is basically finding what the value of x when y is 0; y-intercept is vise-versa.
The format it is currently in is not in y=mx+b form which makes you unable to put on a graph...HOWEVER, YOU ACTUALLY CAN!
You goal for these type of questions is to isolate y by itself.
Your equation has been converted into y=mx+b which now can be used to easily find the x and y intercepts.
<u>You can either look at a graph and find the x and y intercepts or do it algebraically. </u>
Since, "<em>x-intercept is basically finding what the value of x when y is 0</em>", we plug in y with 0.
<u>Solve for X-Intercept: </u>
X-Intercept is -2
<u>Solve for Y-intercept:</u>
Y-Intercept is 5

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 pilot
height/distance = sin x
height/400 = sin 30°
height = sin 30° × 400
height = 1/2 × 400
height = 200
Find the height of second pilot
height/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°
