Answer: 32

Step-by-step explanation:

     When the set has <em>n</em> elements, the power set has 2^n elements. This also gives us the cardinality of the power set, which is what we are looking for.

A = {2,3,9,7,5}

(1) 2

(2) 3

(3) 9

(4) 7

(5) 5

    <em>n</em> = 5

\displaystyle 2^n

\displaystyle 2^5

32

A 4-pound bag of sugar contains 454 one-teaspoon servings and costs $3.49. A batch of muffins uses 1 2 cup of sugar. How many wh
grin007 [14]

Answer:

a) 19 batches

b) $0.18

Step-by-step explanation:

A 4-pound bag of sugar contains 4 54 one-teaspoon servings and costs $3.49. A batch of muffins uses 1/2 cup of sugar.

1 cup = 48 teaspoons

a) How many whole batches can you make if you use as much of the sugar as possible?

1 batch = 1/2 cups of sugar = 24 teaspoons of sugar

Hence,

24 teaspoons of sugar = 1 batch

454 one-teaspoon servings = x

Cross Multiply

24 × x = 1 × 454

x = 454/24

x = 18.9166666667

Approximately to whole batches = 19 batches

b) What is the cost of sugar for each batch?

454 one-teaspoon servings and costs $3.49 = 19 batches

Hence

19 batches = $3.49

1 batch = x

x= $3.49/19

x = $0.18368421052

Approximately = $0.18

Which statement about the function is true?
almond37 [142]

Answer:

A.) The function is increasing for all real values of x where x < -4

Step-by-step explanation:

On the interval x < -4, all of the x values are increasing. Before x = -4, the line assumes a positive slope because it is heading upwards. After this interval, the function is decreasing because the slope is heading downwards.

On the interval -6 < x < -2, all of the x values are positive because they lie above the x-axis. This does not necessarily mean that all of the values are increasing.

On the interval x < -6 and x > -2, all of the x values are negative because they lie below the x-axis.
