Answer:
21/4
Step-by-step explanation:
Rate of change also means slope.
Pick any two points, for example (8,167) and (12, 188)
Now use the formula y2-y1/x2 - x1 to find slope
188 - 167/ 12 - 8
21/4
The rate of change is 21/4, <em>note you would NOT convert the fraction into to a decimal until your teacher specifies you to.</em>
Solving the inequality:
we get 
Step-by-step explanation:
We need to solve the inequality: 
Solving the inequality:
Switch the sides and reverse the inequality:

<h3>let ABC be a triangle</h3>
where,
now
applying tan 30°
tan theta = perpendicular/base
=>tan 30° = 6/a
(since tan 30° = 1/√3)
=>1/√3 = 6/a
=> a = 6√3
applying cos Q for finding b
=>cos 60° = b/h
(since cos 60° = 1/2)
=>1/2= 6/b
=> b= 12
