Answer:

8,139 cubic centimeters

Step-by-step explanation:

Step-by-step explanation:

given f(x) = 2/x and g(x) = 2/x

f(g(x)) = 2/(g(x)) = 2/2/x = x/2 × 2 = x

g(f(x)) = 2/(f(x)) = 2/2/x = x/2 × 2 = x

therefore they are inverses

since f(g(x)) = g(f(x)) = x.

The prediction of a roll of 12 is the expected value of rolling a 12

Jenny can predict 15 as the number of times she will roll a 12

The dice is a 12-sided dice.

This means that the dice has 12 sides.

So, the probability of obtaining a 12 is:

P(12) = 1/12

In a roll of 180 times, the number of times a 12 is expected to show is:

E(x) = np

This gives

E(x) = 180 * 1/12

Evaluate the product

E(x) = 15

Hence, Jenny can predict 15 as the number of times she will roll a 12

Answer:

15. Hope it helps!

Step-by-step explanation:

Answer and Step-by-step explanation:

To solve for x, we need to look at 2 deciding factors that allows us to be able to find x.

We are given 2 parallel lines, denoted by the arrow pointing right on the end of both of them, and a transversal line that cuts through the two lines. Because the lines are parallel, the angles that are formed by the transversal like will be equal or correspondent to each other in a few ways.

For the angles we are given, the angles are on the same side of the transversal line, and on the top of their respective parallel lines. Because of this, the angles are equal to each other.

To solve, set the two angles equal to each other.

4x + 20 = 2x + 60

Subtract the 2x from both sides of the equation.

2x + 20 = 60

Subtract the 20 from both sides of the equation.

2x = 40

Divide both sides by 2.

x = 20

x is equal to 20.

Given -

two parallel lines with a transversal.

To find -

to find the value for x.

Concept applied -

Here in the figure, these two angles let's say 1 = 4x + 20° and 2 = 2x + 60° are corresponding angles. And we know that corresponding angles are equal. As all these angles that have the same position in leu the parallel lines and the transversal are corresponding pairs. Therefore, 1 = 2

Solution -

➙ 4x + 20° = 2x + 60°

➙ 4x - 2x = 60° - 20°

➙ 2x = 40°

➙ x = 40°/2

➙ x = 20°

Henceforth, the value of x = 20°.

Answer: the answer is B,  each term is multiplied by the same number to arrive at the next term

Step-by-step explanation:

Answer:

It's B. Each term is multiplied by the same number to arrive at the next term. as well as D. There is a common ratio between terms.

Step-by-step explanation:

In a geometric sequence, each term is equal to the previous term times a constant, non-zero multiplier called the common factor. Geometric sequences can have a fixed number of terms, or they can be infinite. They must be a progression of terms as well.

Answer:

36/45 and 35/45

Step-by-step explanation:

5 and 9's least common denominator is 45 and to get to that you need to multiply both top and bottom of how to get to 45. How I got to 45 the easiest way is to keep multiplying both numbers until the reach the same product. In this case for 4/5, you multiply it by 9 for top and bottom. And for 7/9, it would be multiplying by 5 for top and bottom which will get you both of the answers. Hopefully this answers your question.

Answer:

The rate of change, slope, m is

m=(y2-y1)/(x2-x1), we have points (4,5) and (21,39) so

m=(39-5)/(21-4)

m=34/17

m=2

So the rate of change is 2

Line 2 presents the error for the solution presented because the square of numbers: 14 and 8 was calculated incorrectly.

This law can be applied when two sides of the triangle and the angle formed for these sides are known. Therefore, from the law of cosines, it is possible to write the relation between sides and their respective cosines. See below:

                           [tex]c^2=a^2+b^2-2*a*b*cos(C)[/tex]

For solving this question, you should apply the Law Cosines and after that compare your solution with this exercise. From the comparison, you should identify the mistake for the solution presented in this problem.

                 [tex]c^2=a^2+b^2-2*a*b*cos(C)\\ \\ c^2=14^2+8^2-2*14*8*cos(80)\\ \\ c^2=196+64-224*0.1736\\ \\ c^2=196+64-38.8864\\ \\ c^2=221.1136\\ \\ c=\sqrt{221.1136}=14.9[/tex]

He made the error in line 2. Instead of calculating the square of 14 and 8, he multiplied these numbers by 2. This was the error.
