The answer to this question is choice B. To complete the square, we take the coefficient on the x term, halve it, and then square it. This results in -9/2, and then 81/4. This value of 81/4 is added to both sides, allowing for factorization of the lefthand side of the equation.

What is the average rate of change for the sequence shown below?

Mkey [24]

Hey There!

To find the rate of change, simply use the following formula.

y2 - y1 = x2 - x1

Keeping this in mind, let's begin to solve.

3 - 4 = -1

1 - (-1) = 2

Therefore, the answer would be C

Would an experience downhill skier want the slope of the hill to be 1/10 or 9/10? Why?<br><br>

kolezko [41]

Answer:

9/10

Step-by-step explanation:

step 1

Compare the slopes

$1/10=0.10$

$9/10=0.9$

$0.9 > 0.10$

therefore

An experienced skier would like the 9/10 hill slope because it is steeper, while the 1/10 is a softer slope.
