Answer:
Step-by-step explanation:
okay don't feel bad, you actually got it right, let me help you with some holes!
You calculate slope by the rise over run. These people are confusing you a bit - do problem 2 then 1
the vertical change is -1 horizontal change is 3 so by rise/run=-1/3
-1/3 is the slope
for the second problem this is confusing but just read and try to analyze
vertical change/horizontal change = 5-4/0-3= 1/-3(or -1/3)
The y intercept is the point where the line hits the y axis, so at point (0, 5)
The function is y=mx+b
m is the slope
b is the y intercept
so y=-1/3x+5

Determine the percentage of protein
First, we need to calculate the total:
Percentage of protein is calculated as thus:
that is, hypotenuse.
Therefore, let the length of the hypotenuse be 'x.'
625+3600=
4225=
Therefore,
=x
65=x
The length of the hypotenuse is B.65 centimetres.
Answer:
D.) Quadrant 4
Step-by-step explanation:
Sin theta < 0 tells us the angle is in quadrant 3 or 4
The y component is negative
Cos theta >0 tells us the angle is in quadrant 1 or 4
The x component is positive
Therefore theta must be in quadrant 4
