I believe the average rate of change is 1

9514 1404 393

Answer:

  -1

Step-by-step explanation:

The graph goes through the points (-1, 1) and (1, -1). The average rate of change is the slope of the line through those points. It can be calculated using the slope formula. Alternatively, you can recognize that the line will have a "rise" of -1 for each "run" of 1, so rise/run = -1/1 = -1.

__

Using the slope formula, we have ...

  m = (y2 -y1)/(x2 -x1)

  m = (-1 -1)/(1 -(-1)) = -2/2 = -1

The average rate of change on the interval is -1.

Q 1: You are making chocolate chip cookies. The recipe calls for 1/8 teaspoon salt to 1/4 teaspoon baking soda. How much baking soda is needed for 1 teaspoon of salt?
Q 2:Use the information contained within the question one. How much salt is needed for 1 teaspoon of baking soda?

Answers

Answer:

x = teaspoon of soda needed = 2 teaspoons of baking soda for 1 teaspoon of salt

y = teaspoons of baking soda needed = 1/2 teaspoons of salt needed for 1 teaspoon of baking soda

Step-by-step explanation:

Teaspoon of salt : Teaspoon of soda

1/8 : 1/4

How much baking soda is needed for 1 teaspoon of salt?

Let

x = teaspoon of soda needed

Teaspoon of salt : Teaspoon of soda

1 : x

Equate both proportion

Teaspoon of salt : Teaspoon of soda

1/8 : 1/4 = 1 : x

1/8 ÷ 1/4 = 1/x

1/8 × 4/1 = 1/x

4/8 = 1/x

Cross product

4*x = 8*1

4x = 8

x = 8/4

= 2

x = 2 teaspoons of

x = teaspoon of soda needed = 2 teaspoons for 1 teaspoon of salt

2. How much salt is needed for 1 teaspoon of baking soda?

Let y = teaspoons of baking soda needed

Teaspoon of salt : Teaspoon of soda = y : 1

Equate the proportion

1/8 : 1/4 = y : 1

1/8 ÷ 1/4 = y / 1

1/8 × 4/1 = y / 1

4/8 = y / 1

Cross product

4 * 1 = 8 * y

4 = 8y

y = 4/8

= 1/2

y = 1/2 teaspoons of baking soda

y = teaspoons of baking soda needed = 1/2 teaspoons needed for 1 teaspoon of baking soda

Let the measure of the other interior angle = M

The exterior angle is equal to the sum of the interior angles in a given triangle.

An exterior angle of a triangle has a measure of 80°, and one of the remote interior angles has a measure of 20°.

This means,

M + 20 = 80

Solve for M.

M + 20 = 80

Subtract 20 on both sides.

M = 80 - 20

M = 60

Thus,

The measure of the other remote interior angle is 60°.

Answers

Answer: the ANSWER IS 11 sqt

Step-by-step explanation:

Factor 1331 into its prime factors

          1331 = 113

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

Factors which will be extracted are :

          121 = 112

Factors which will remain inside the root are :

          11 = 11

To complete the simplification we take the squre root of the factors which are to be extracted. We do this by dividing their exponents by 2 :

          11 = 11

The simplified SQRT looks like this:

        11 • sqrt (11)  

Simplified Root :

11 • sqrt(11)

The Answer is going to 11
