Find cardinality of set B

B = {∅, {1}, {1, 2}, {1, 2,3}, · · · , {1, 2, · · · , m}}

Answers

Answer:

m + 1

Step-by-step explanation:

Given set,

B = {∅, {1}, {1, 2}, {1, 2,3}, · · · , {1, 2, · · · , m}},

Since, the elements of S are,

{} , {1}, {1, 2}, {1, 2, 3}....... {1, 2,.....m }

Thus, every next set contains one more succeeding natural number than the previous set.

So, if the last set contains m natural numbers.

Then there are 'm + 1' sets in B ( m sets included ∅ )

Hence, the number of elements in B is 'm+1'

I.e. Cardinality of B is m + 1.

Answers

Answer:

75 ft

Step-by-step explanation:

Here we are given a right angled triangle with a known angle of 20°, length of the hypotenuse to be 80 and we are to find the length of the base x.

For that, we can use the formula for cosine for which we need an angle and the lengths of base and hypotenuse.

cos \alpha =(base)/(hypotenuse)

So putting in the given values to get:

cos 20=(x)/(80) \n\nx= cos 20*80\n\nx=75.17

Therefore, the value of x is the closest to 75 ft.

A linear function m models the amount of milk sold by a farm per month. The amount decreases 500 gallons for every $1 increase in price. Graph m when m(0)=3000. Identify the slope. Interpret the x- and y-intercepts of the graph.

Answers

The linear function that models this situation is:

m(x) = 3000 - 500x, 0 \leq x \leq 6

  • The y-intercept is y = 3000, which means that when there is no increase on the price, the farm sells 3000 gallons.
  • The x-intercept is x = 6, which means that if the price increases $6, no gallons will be sold.
  • The slope is of -500.
  • The graph is sketched at the end of this answer.

The equation of a line has the following format:

y = ax + b

In which:

  • a is the slope, which is by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0.

In this problem, m(0) = 3000, thus, b = 3000, that is:

  • The y-intercept is y = 3000, which means that when there is no increase on the price, the farm sells 3000 gallons.

The amount decreases 500 gallons for every $1 increase in price, thus, the slope is -500, and the equation is:

m(x) = 3000 - 500x

The x-intercept is the value of x for which:

m(x) = 0

Then

500x = 3000

x = (3000)/(500)

x = 6

  • The x-intercept is x = 6, which means that if the price increases $6, no gallons will be sold.

Answer:

Slope of the graph -500 gallons per dollar.

Intercept is 3000.

Step-by-step explanation:

General format of an equation of a linear graph is;

y=mx+c

Where,

y is the dependent variable

m is the slope of the graph

x is the independent variable of the graph

c is the intercept of the graph.

m(0)=3000 means when we substitute 0 for x values of the graph the y value is 3000. Therefore the intercept is 3000.

Slope of the graph = (-500gallons)/(1dollar)

                               =-500 gallons per dollar.

So we can write the equation as;

y=-500x+3000

but in this question y is given as m. Therefore function can be re-written as:

m=-500x+3000

The graph is attached with the answer.
