Answer:
-3/2
Step-by-step explanation:
The average rate of change is synonymous to the slope.
So, to find the average rate of change from the interval x=-2 to x=2, first find the y-values at x=-2 and x=2.
At x=-2, we can see that y is 4. Thus, we have (-2,4).
At x=2, we can see that y is -2. Thus, we have (2,-2).
Now, use the slope formula. The formula for slope is:
Let (-2,4) be x₁ and y₁ and let (2,-2) be x₂ and y₂. Therefore:
Simplify:
Reduce:
So, our average rate of change from the interval x=-2 to x=2 is -3/2.
The formula for an area of a circle is pi•r^2.
The diameter is 16, so the radius (half of the diameter) is 8. plug that into the formula and you get 64pi, or roughly 200.96
Using proportions, it is found that each of the 6 people got $0.5.
<h3>Proportions:</h3>
- This question is solved by <em>proportions</em>, using a rule of three.
- $3.00 is shared between 6 people, which are Larry, Curly, Moe, Alvin, Simon and Theodore. How much did each people(1 person) get?
The <em>rule of three</em> is:
$3.00 - 6 people
$x - 1 person
Applying cross multiplication:
Each of the 6 people got $0.5.

Answer:
150(0.4),2,500(0.11)
Step-by-step explanation:The first question says 150 participants and 40%of the participants are eliminated. so it's 150(0.4)n
same goes for the second 2,500 bacteria in a colony the colony grows at a rate of 11% every hour so the answer to the question is 2,500(0.11)n
-60 -90 -120 it’s going by -30 and that should figure out the next three te rms
