Question: Which expression is undefined in the set of real numbers? A √-4 B 0/-4 с 0-4 D - 4x0​

Answer:

B

Step-by-step explanation:

Here, let find some discontinuity in the y direction.

We have a removable discontinuity (a hole) at y=-4

We have a horizontal asymptote ( infinite discontinuity)

at y=-3.

This means our y values will approach -3 but not reach -3.

Our y values can be either negative or positive.

So our range is All Reals except -3 and -4.

They need to sell 18 pieces to cover their expenditures (have a profit of zero).

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

here, we have,

How many cakes will they have sold?

We know that the costs are:

$36 for the booth at the fair.

$6 for each piece of cake they sell.

And the revenue is:

$8 for each piece of cake.

So, the profit (the difference between the revenue and the cost) for selling x pieces is:

p(x) = $8*x - $6*x - $36

p(x) = $2*x - $36

We want to find the value of x such that p(x) = 0, then:

0 =  $2*x - $36

x = $36/$2

  = 18

They need to sell 18 pieces to cover their expenditures (have a profit of zero).

Answer:

A

Step-by-step explanation:

Answer:

D. 9/40 would be the answer.

Step-by-step explanation:

formula

sinQ= opp/hyp (9/41)

TanQ= opp/adj (which mean 9 /40)

Since the triangles are congruent. Then The size of angle Q is 47°

Congruent Angle:

Congruent angles are often used in architecture, construction, design, and art. Isometrics have the same angular measurements. For example, a regular pentagon has 5 sides and 5 angles, each measuring 108 degrees. Regardless of the size or scale of a regular polygon, the angles are always congruent.

Here is a list of rules for the congruence of angles.

1. The only condition for two angles to be congruent is if the measurements of the angles agree.

2. The lengths and orientations of the two sides of this congruent angle are not important.

According to the Question:

It is given that :

B = 6 cm, 12 cm and 9 cm

A = 47°

R' = 29°

If the triangle is congruent, then all the three sides and angles will be same.

Therefore,

Angle Q = Angle A

Therefore, Angle Q = 47°

The sale of the four different sizes is an illustration of the Goodness of Fit Tests

The expected counts for each size box are 0.8, 3.6, 36.6 and 4.05 respectively

The null hypothesis is always represented by the equality sign i.e. 0 change or no change.

While the alternate hypothesis is always represented by an inequality.

So, the null and the alternate hypotheses are:

This calculated as:

E(x) = np

So, we have:

Small = 8 * 10% = 0.8

Medium = 24 * 15% = 3.6

Large = 61 * 60% = 36.6

Jumbo = 27 * 15% = 4.05

Answer:

Step-by-step explanation:

Not sure what the question is but...

At 4 o clock Devon + 6 people know the weather forecast

At 6 o clock the 6 people that know the weather forecast call another 6 people, making it a total of 36 people + Devon who know about the weather forecast. To find the amount of people called, subtract 36 by 6, which means 30 people were called.

At 8 o clock the 30 friends who were informed about the weather forecast each call another 6 of their friends. 6*30 is 180. So, 180 + Devon knows about the weather forecast. In total 180 + Devon knows about the weather forecast. The find the amount of people called at 8 o clock, subtract 180 by 30, so 150 people were called at 8 o clock.

My own multi-step combination problem is given below:

To solve this problem, Amanda  need to use the formula for combinations and it is:

nCr = n! / (r! x (n-r)!)

where:

n = total number of items to select from

r is the number of items to select.

First, we have to calculate the number of ways to select 3 fruit from 5, hence it will be:

5C3

=  5! / (3! x (5-3)!)

= 10

Next, we have to calculate the number of ways to select 2 meatpie from 4 and it will be

4C2

= 4! / (2! x  (4-2)!)

= 6

Lastly,, we need to calculate the number of ways to select 2 desserts from 3 and it will be:

3C2

= 3! / (2! x  (3-2)!)

= 3

To have the total number of dinner menus, we have to multiply these three numbers together:

= 10 x 6 x 3

= 180

Therefore, one can say that Amanda have 180 different dinner menus that she can be create.

The value of sin is : 12/13

Step-by-step explanation:

The formula for cosine of an angle is the length adjacent to that angle divided by the hypotenuse.

This means if ;

cos∅ = A/H  

then using this information and given that;

cos ∅ = 5 by 13

cos ∅ = 5/13

You can find the opposite side length from Pythagorean relationship as;

13²-5²=b²

144 = b²

√144 = b

12 = b

Opposite side length = 12

Sin ∅ = opposite side length / hypotenuse

Sin ∅ = 12/13

the vector function that represents the curve of intersection is:

\(r( t)=t\hat{i}+3t^2\hat{j}+(3t^2+18t^4)\hat{k},\)

A vector-valued function, also referred to as a vector function, is a mathematical function of one or more variables whose range is a set of multidimensional vectors or infinite-dimensional vectors. The input of a vector-valued function could be a scalar or a vector (that is, the dimension of the domain could be 1 or greater than 1); the dimension of the function's domain has no relation to the dimension of its range.

First plug the equation of y into the equation of z, so that we get their intersection:

We plug\(y=3x^2\ into \ z=3x^2+2y^2\)

We get ,

\(z=3x^2+18x^4\)

Then we set x=t

And plug that in the equation and the one we just got for z.

\(y=3t^2 , z=3t^2+18t^4\)

Therefore, the vector function that represents the curve of intersection is:

\(r( t)=t\hat{i}+3t^2\hat{j}+(3t^2+18t^4)\hat{k},\)
