Answer:
First Option: cos(x)
Step-by-step explanation:
What is given is csc(x) = 14/10
The graph lies in the first quadrant since 0 < x < pi/2
Create a triangle:
The length across is 14
The adjacent is 10
The length of the shorter side is root 96
Use the pythagorean theorem
BC^2 = 14^2 - 10^2
BC^2 = 196 - 100, 96
BC^2 = root 96/14
Recall SOH-CAH-TOA
Adjacent over Hypotenuse is cos
That is how the answer is cos(x)
5x+4y=16 y=3/5x-3
y=mx+b <------ slope-intercept form
5x+4y=16
-5x -5x
============
4y=-5x+16
--------------
4
============
y= -5/4+4
Slope is -5/4
y-intercept is 4
y=3/5x-3
slope is 3/5
y intercept is -3
I can't do the graph but I'm sure you can figure it out!
Hope I helped.
Answer:
c.
Step-by-step explanation:
It's B) A straight line can be drawn through all the points and the line passes through the point (0,0)
This is because in the problem it says that the points are paired and proportional. For example, say you're given the point (3,6). To make this a proportional relationship, you'd have another point in the third quadrant: (-3,-6). When you draw a line from one of these points to the other, it passes through the origin.
