Answer:
Option 2 which is r^6
Step-by-step explanation:
You need to apply the exponent rules.
Since the r's are the same, you can subtract the exponents.
r^9 - r^3 = r^6
Notice that the bases ("r") stayed the same.
Answer: Choice [B] -r^6 ✅
Step-by-step explanation:
Hii!
Do you need to know the answer to your question? No problem!
We can use the Exponents' Property of division to work out the answer to this particular problem. (:
This property says that if you divide two numbers with the same base, you subtract their exponents.
Do we have the same base here? Yea', sure! The same variable can't stand for two different numbers in the same expression.
Let's work out the answer!
[tex]\LARGE\boldsymbol{r^9/r^3=r^{9-3}=r^6}[/tex]
Voila! There's our answer, cheers!

what are the x-intercept(s) of the function
Answers
To find the zeros of a rational function, we must identify values of x that make the numerator equal to 0. We can do this by factoring and by keeping in mind the zero-product property.
The zero-product property states that if the product of two terms is 0, then one of the terms must be equal to 0.
Solving the QuestionWe're given:
[tex]f(x)=\dfrac{4x^2-36x}{x-9}[/tex]
First, factor 4x out of the numerator:
[tex]f(x)=\dfrac{4x(x-9)}{x-9}[/tex]
Let f(x) = 0:
[tex]0=\dfrac{4x(x-9)}{x-9}[/tex]
In this case, either x or (x-9) is equal to zero, as they are the two terms being multiplied in the numerator to get 0 as a product.
This makes the x-intercepts of this function 0 and 9.
However, the denominator in this function is x - 9. If x = 9, then it would make the denominator 0, which is not allowed. Therefore, x cannot equal 9, and the only x-intercept is 0.
Answerx = 0

Answer: D. 60x²y⁸ is the simplified form of the fifth term of the
expansion ⁶C₄ (2x)² (-y²)⁴.
What is an Expression?An expression is a sentence with a minimum of two numbers or variables and at least one math operation.
This math operation can be addition, subtraction, multiplication, or division.
According to the Given Expression,
⁶C₄ (2x)² (-y²)⁴
The value of the combination can be written as,
[tex]= [\frac{6!}{4!(6-4)!} ] (2x)^{2} (-y^{2})^{4}[/tex]
= 15 (4x²) (-y²)⁴
The value of y can be written as,

What is Angle?A figure which is formed by two rays or lines that shares a common endpoint is called an angle.
Here,
Theta (angle) θ = arc length / radius
θ = 15 π / 60 cm
θ = 0.79 radians
Convert to degrees
θ = 0.79 radians = 0.79 X 180/ π
= 0.79 X 180/ 3.14
= 45⁰

A charity bingo game costs $2 per round and has a $13 entry fee for an adult. It costs $3 per round and a $10 entry fee for a child. For how many rounds of bingo are the costs the same for an adult and a child?.
Answers
The number of rounds of bingo when the two costs would be the same is 3.
When would the two costs be the same?The equation that represents the total cost for adults is : 13 +2r
The equation that represents the total cost for children: 10 + 3r
where r is the number of rounds
When the two costs are the same, the two above equations would be equal: 13 + 2r = 10 + 3r
13 - 10 = 3r - 2r

t = 2
Step-by-step explanation:
Look at the fraction on the left, 1/3.
Notice that the denominator is 3 times the numerator.
Since the fractions are equal, for the second fraction, you also need the denominator to be 3 times the numerator. Since the denominator is 6, the numerator must be 2 since 6 is 3 times 2.
Answer: t = 2
Of course, since you have two fractions that are equal, and fractions are also ratios, you have a proportion.
You can solve the problem as a proportion.
1/3 = t/6
Cross multiply:
3t = 1 × 6
3t = 6
t = 6/3
t = 2
Either way, you get t = 2.
