Jacinta says that the product of a rational number and an irrational number is always irrational. Explain her error.
Jacinta says that the product of a rational number and an irrational number is always irrational her claim is wrong.
What is a rational number?A rational number is one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.
Irrational numbers are all real numbers that are not rational numbers in mathematics. Irrational numbers, on the other hand, cannot be stated as the ratio of two integers. Decimal notation is the term used to describe the method of representing numbers in the decimal system.
Given that Jacinta says that the product of a rational number and an irrational number is always irrational.
Her statement is incorrect because if 0 a rational number is multiplied with the π which is irrational then the result will be 0 which is rational.
Therefore, Jacinta's claim is wrong.

This is the graph of f(x) = x+A/x+B. The grid lines in the graph are one unit apart. What is the value of A/B
The value of A/B is given as follows:
A/B = -2.
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:
B = -1 -> as x + B = 0 -> x = -B = -1.
When x = 0, y = -2, hence the value of A is obtained as follows:
A/-1 = -2
A = 2.
Then the division is given as follows:
A/B = 2/-1 = -2.

19/20 + (−18/20) + 17/20 + (−16/20) + ... + (−4/20) + 3/20 + (−2/20) + 1/20
Answer:
\(\frac{1}{2}\)
Step-by-step explanation:
There is a pattern. All the odd numbers are positive. \(\frac{19}{20}\), \(\frac{17}{20}\), \(\frac{3}{20}\), \(\frac{1}{20}\) and the even numbers are positive \(\frac{-18}{20}\), \(\frac{-16}{20}\), \(\frac{-4}{20}\), \(\frac{-2}{20}\). The three dots in between mean to include the fractions inbetween \(\frac{-16}{20}\) and \(\frac{-4}{20}\). This is \(\frac{15}{20}\) to \(\frac{5}{20}\). Because all the fractions have a denominator of 20 every number between 5 and 15 is the numerator and 20 is the denominator.

What is the measure of angle C?
Answer:
x = 29
Angle C = 93°
Step-by-step explanation:
Since all of the interior angles of a triangle add up to 180° and we are given the values of angle A and angle B, we can find angle C by subtracting A and B from 180.
35 + 52 = 87
180 - 87 = 93
Thus, the measure of angle C is 93°.
Now that we know the measure of angle C, we can determine the value of x.
Set up an equation:
3(x + 2) = 93
3x + 6 = 93
3x = 87
x = 29
Answer:
x = 29
Angle C = 93

Jacob mixes 1/3 cup of yellow paint for every 1/5 cup of blue paint to make green paint. How many cups of yellow paint are needed for 1 cup of blue paint?
A. 2/3 cups
B. 1/2 cups
C. 1 1/2 cups
D. 1 2/3 cups
Answer:
1 2/3 cups
Step-by-step Explanation:
If Jacob uses 1/3 cup of yellow paint for every 1/5 cup of blue paint to make green paint.
If he needed one cup of blue paint he would have to get 5, 1/5 cups for get a full cup.
So if he needed 1/3 cup of yellow paint for every 1/5 cup of blue paint he would also need to get 5, 1/3 cups of yellow paint. Which would leave him with 5/3 cups of yellow paint, which simplifies to 1 2/3 cups of yellow paint and 1 cup of blue paint.

The number of players participating in an online game increases each
day. On the day of the game's release, there are no players. One day
after the release of the game, there are 1,208 players. Two days after
the release, there are 2,398 players. Three days after the release, the
game has 3,621 players.
• Create an equation to approximate the number of players, p, that
will participate in the game d days after the game's release.
Explain how you created this equation.
• Using your equation, estimate how many players there will be
7 days after the game's release.
Enter your equation, your explanation, and your answer in the space
provided.
Hi ttttttttthhhhhhhheeeeeeerrrrrrreeeeeee!!!
The number of players there will be 7 days after the game's release is 0.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that;
We have four data points: (0, 0), (1, 1208), (2, 2398), and (3, 3621).
Now,
These points represent the pairs of days and players for the game. We can substitute these points into the general exponential equation and solve for a and b. In general, we have to solve this system of equations:
p = ab^d 0 = ab^0 1208 = ab^1 2398 = ab^2 3621 = ab^3
We can simplify the first equation by using the fact that b^0 = 1 for any nonzero b. This gives us:
0 = a
This means that a is zero, which makes sense because there are no players on the day of the game’s release. We can substitute a = 0 into the other equations and solve for b. This gives us:
1208 = 0b^1 2398 = 0b^2 3621 = 0b^3
We can divide each equation by 1208 to get:
1 = b 1.98 ≈ b^2 2.99 ≈ b^3
We can take the cube root of the last equation to get:
b ≈ 1.44
This means that b is approximately 1.44, which means that the number of players increases by about 44% each day. We can substitute a = 0 and b = 1.44 into the general exponential equation to get:
p ≈ 0(1.44)^d
This is our exponential equation that approximates the number of players for the game.
Using this equation, we can estimate how many players there will be 7 days after the game’s release by plugging in d = 7 and solving for p. This gives us:
p ≈ 0(1.44)^7 p ≈ 0(5.38) p ≈ 0
Therefore, by the equation the answer will be 0.
