Answer:
The answer to your question is: 161x + 17y - 391 = 0
Step-by-step explanation:
Data
y-intercept = 23 Get the points (0, 23)
x- intercept = 4.75 (4.75, 0)
4.75 = 17/4 (17/4, 0)
slope
m = (y2 - y1) / (x2 - x1)
m = (0 - 23) / (17/4 - 0)
m = -23 / 17/4
m = - 161 / 17
equation
(y - y1) = m (x - x1)
( y - 23) = -161 / 17 (x - 0)
y - 23 = -161/17 x
17(y - 23) = -161x
17y - 391 = -161x
161x + 17y - 391 = 0
Answer:
Step-by-step explanation:
For plane A,
Equation that represents the relationship between time 'x' and distance 'y' is,
y = 470x
By comparing this equation with the slope-intercept form of the equation,
y = mx + b
m = slope = 470
b = 0
Here, slope represents the speed of plane A.
Therefore, speed of plane A = 470 mi per hour
For plane B,
From the given table,
Slope of the graph = 
= 
= 480
Speed of plane B = 480 miles per hour
Since, speed of plane B is more than plane A,
Plane B is flying faster.
If sinα=1/4 and it is in q2 it means that the x coordinate is negative.
The triangle has a height of one and a hypotenuse of 4 so:
x=-√(4^2-1)
x=-√15
so tanα=-1/√15
tanα=-√(1/15)
tanα≈ -0.258
