Given a table, with an input (x) and output (y) , you could actually use the slope formula to get the rate of change because slope is the same thing as rate of change. If you recall, the slope formula is (y2-y1)÷(x2-x1)
Just pick two points from the chart and plug them in and that is your rate of change
Answer:

Step-by-step explanation:
In the triangle,
Hypotenuse = 13
Opposite = Perpendicular = 5
Adjacent = Base = 12
Now,
Cos B = 
Cos B = 12/13
If the triangle is just like in the attached file!
Answer:
D. 15G > 9
Step-by-step explanation:
Given: G = 3/5
Here we have to check each options and find which is true.
Let's start from A.
G - 1 > 2/5
G > 2/5 + 1
G > 7/5 is not true.
B. -10G > 6
Dividing both sides by -10 , we get
G < -6/10
G < -3/5 Is not true.
C. 1 2/5 + G > 3
Now convert 1 2/5 to improper fraction.
1 2/5 = 7/5
7/5 + G > 3
G > 3 - 7/5
G > (15 - 7)/5
G > 8/5 is not rule.
D. 15G > 9
Dividing both sides by 15, we get
G > 9/15
Now we have to simplify 9/15
G > 3/5 which is true.
Answer: D. 15G > 9
Thank you.
