Step-by-step explanation:
x = −3
⇒ asymptote
x = −2
⇒ asymptote
x = 0
⇒ hole
x = 2
⇒ neither
x = 3
⇒ neither
x = 5
⇒ neither
To determine whether each value of x is a discontinuity of the function, we analyze the function to find asymptotes or holes. For the given function, x = -2 and x = -3 are asymptotes, x = 0 is a hole, and the remaining values of x do not create any discontinuities.
Explanation:To determine whether each value of x is a discontinuity of the function, we need to analyze the function and look for asymptotes or holes. Let's consider the function f(x) = (5x) / (x^3 + 5x^2 + 6x).
To identify asymptotes, we need to find the values of x where the denominator of the function is equal to zero. For x = -2 and x = -3, the denominator becomes zero, which indicates that there are vertical asymptotes at x = -2 and x = -3. These values are neither holes nor asymptotes.
For x = 0, the denominator also becomes zero, but the numerator is not zero. This indicates that there is a hole at x = 0.
For the remaining values of x (2, 3, and 5), neither the numerator nor the denominator becomes zero. Therefore, these values do not create either holes or asymptotes. So the answer is:
x = -3: asymptotex = -2: asymptotex = 0: holex = 2: neitherx = 3: neitherx = 5: neitherFind the unknown side of the triangle below
A. 4cm
B. 3cm
C. 9cm
D. 19cm
Answer:
C - 9 cm
Step-by-step explanation:
We can use the Pythagorean theorem to figure out the missing side length, in this case, X.
The Pythagorean theorem states: a^2 + b^2 = c^2, with c being the hypotenuse. We have the side length of the hypotenuse which is 15, and we have another side length of 12. Let's put these back in our equation:
a^2 + 12^2 = 15^2;
If we simplify the squares by simply doing them: a^2 + 144 = 225;
Now let's subtract 144 from both sides to isolate the variable, a:
a^2 = 81;
Now we square both sides to find a:
a = 9
The missing side length is 9 cm.

Problem 1.
How much greater is -20x^2 + 5x + 17 than -19x^2 + 20x + 18
Problem 1. Solution:
Subtract the second polynomial from the first polynomial.
-20x^2 + 5x + 17 - (-19x^2 + 20x + 18) =
To simplify the parentheses, think of the negative sign left of the parentheses as the number -1, and distribute it using the distributive property.

The seven students in a sewing
class equally share the cost of
fabric and other supplies. Last
month, each student paid ($167.94
+ $21.41) / 7. This month, each
student paid ($77.23 + $ 6.49) / 7.
Without doing any calculations, in
which month did each student pay
more?
Answer:
Last month
Step-by-step explanation:
Just look at the numbers.
The first number is (167.94 + 21.41) / 7 and the second number is (77.23 + 6.49) / 7. We see that they both have the denominator of 7, so we can just focus on comparing the numerators.
Look at 167.94 + 21.41. Clearly, 167.94 is bigger than 77.23 from the second number. We also see that 21.41 is clearly bigger than 6.49. If both numbers of the first number are bigger than both numbers from the second number, we know that the sum of the first two numbers will be bigger than the second sum.
Thus, the bigger the numerator, the bigger the amount paid, even including the dividing 7 at the end.
Thus, last month, the students had to pay more.
Hope this helps!

Solve this question: Can you make 100 by interspersing any number of pluses and minuses within the string of digits 9 8 7 6 5 4 3 2 1? You can’t change the order of the digits! So what’s the least number of pluses and minuses needed to make 100? For instance, 98 - 7 - 6 + 54 - 32 shows one way of interspersing pluses and minuses, but since it equals 107, it’s not a solution.
Answer:
98-76+54+3+21=100
1 Plus3 MinusesStep-by-step explanation:
Possible Variants are:
[tex]98 - 76 + 54 + 3 + 21 = 100\\9 - 8 + 76 + 54 - 32 + 1 = 100\\98 + 7 + 6 - 5 - 4 - 3 + 2 - 1 = 100\\98 - 7 - 6 - 5 - 4 + 3 + 21 = 100\\9 - 8 + 76 - 5 + 4 + 3 + 21 = 100\\98 - 7 + 6 + 5 + 4 - 3 - 2 - 1 = 100\\98 + 7 - 6 + 5 - 4 + 3 - 2 - 1 = 100[/tex]
[tex]98 + 7 - 6 + 5 - 4 - 3 + 2 + 1 = 100\\98 - 7 + 6 + 5 - 4 + 3 - 2 + 1 = 100\\98 - 7 + 6 - 5 + 4 + 3 + 2 - 1 = 100\\98 + 7 - 6 - 5 + 4 + 3 - 2 + 1 = 100\\98 - 7 - 6 + 5 + 4 + 3 + 2 + 1 = 100\\9 + 8 + 76 + 5 + 4 - 3 + 2 - 1 = 100\\9 + 8 + 76 + 5 - 4 + 3 + 2 + 1 = 100\\9 - 8 + 7 + 65 - 4 + 32 - 1 = 100\\[/tex]
From:
98-76+54+3+21=100
The least number of plus and minuses needed to make 100 are 1 and 3 respectively.
The least number of pluses and minuses needed to arrange the numbers 9 8 7 6 5 4 3 2 1 to equal 100 is four. A valid combination resulting in 100 is 98 - 7 + 65 + 43 - 21 which uses two minuses and two pluses.
Explanation:Your question asks how many pluses and minuses can be inserted in the string 9 8 7 6 5 4 3 2 1 without altering its order to make 100. An interesting mathematical challenge problem indeed!
Remember, this question pertains to arithmetic operations of addition (+) and subtraction (-). A possible solution can be 98 - 7 + 65 + 43 - 21. This results in 100 with four total operations interspersed (two minuses and two pluses).
By using the arithmetic operations strategically, the least number of pluses and minuses (total four) you need to yield 100 is produced. Hence, this combination of digits and operators achieve the intended sum balancing positive and negative values.

Which equation is equivalent to f(x) = -3(x-2)2 + 14?
The given function f(x) = -3(x-2)^2 + 14 is a quadratic equation shown in vertex form. To find an equivalent equation in standard form or solve for its roots, one can expand and simplify or use the quadratic formula with the appropriate coefficients.
The equation f(x) = -3(x-2)^2 + 14 is a quadratic equation in vertex form. In standard form, a quadratic equation is represented as at^2 + bt + c = 0. To express f(x) in this standard form, we simply need to expand the squared term and simplify. The given equation already shows that the parabola has been reflected vertically due to the negative sign before the coefficient of the squared term, and it is shifted 2 units to the right and 14 units up from the origin.
Transformations of the independent variable such as multiplying by a constant or adding a number, like in f(2x) or f(-2x), will affect the graph of the quadratic function. They result in horizontal scaling or reflection, while transformations like f{-2(x+1)} involve horizontal shifting.
To solve a quadratic equation that is set equal to zero, we can use the quadratic formula, which employs the coefficients a, b, and c. As an example, for a quadratic equation with constants a = 4.90, b = 14.3, and c = -20.0, the roots can be found through this formula.
hurry plzzzzz!!!!!!!!!!!!! Find the height of a square pyramid that has a volume of 75 cubic feet and a base length of 5 feet. A:5 feet B:9 feet C:25 feet D:45 feet
Answer:
B
Step-by-step explanation:
The volume of a square pyramid can be found using:
v=1/3 bh
Where b is the area of the base, and h is the height
First, let's find the area of the base
a=l*l
We know the length is 5, so we can substitute it in
a=5*5
a=25
Now we know b(area), is 25, and we know the volume is 75, so we can substitute them in
v=1/3 bh
75=1/3(25)h
Divide both sides by 1/3, or multiply both sides by the reciprocal, 3/1
225=25h
Divide both sides by 25
h=9
So, the height is 9 feet , or choice B

The area of Brian's cake's top = base x height
= 13 x 9
= 117 square inches
Area of Nancy's cake's top = [tex]\frac{1}{2\\}[/tex] x base x height
= [tex]\frac{1}{2}[/tex] x 15 x 12
= 6 x 15
= 90 square inches
Therefore, Brian's cake's top has a greater area than Nancy's.
Answer:
Brian's parallelogram-shaped cake top had the greater area. It was 27 in² greater than Nancy's cake top.
Step-by-step explanation:
To find the area of a parallelogram, use the formula A = b × h, where A is the area, b is the base and h is the height. Substitute the base and height into the equation.
A = 13 × 9
Then work out the equation to get:
117 = 13 × 9
This means that Brian's cake top has an area of 117 in².
Next, find the area of a triangle using the formula A = [tex]\frac{bh}{2}[/tex], where A is the area, b is the base, and h is the height. Substitute the base and height into the equation.
A = [tex]\frac{15*12}{2}[/tex]
The * symbol means the same as multiply.
Then work out the equation to get:
180 = [tex]\frac{15*12}{2}[/tex]
This means that Nancy's cake top has an area of 90 in².
We can see that Brian's cake top has a greater area than Nancy's already, but to find out how much greater, just subtract 90 from 117:
117 - 90 = 27
Hence, Brian's cake top has a greater area of 27 in².

Use the information to write an equation with variables on both sides. Let x represent Kim’s age.
Bob is 4 years older than twice Kim’s age.
Paul is 1 year younger than 3 times Kim's age.
Bob and Paul are the same age.
Which equation can be used to determine Kim’s age, x, from the information about Bob and Paul?
4x + 2 = 3x + 1
4x + 2 = 3x + (–1)
2x + 4 = 3x + 1
2x + 4 = 3x + (–1)
Hey! I hope this helps!
Answer:2x + 4 = 3x+ (-1)
Option D)
Step-by-step explanation:We are given the following in the question:
Let x represent Kim's age
"Bob is 4 years older than twice Kim's age"
Thus, Bob's age =
4 + 2x years
"Paul is 1 year younger than 3 times Kim's age."
Thus. Paul's age is
(3x - 1) years
If Bob's age and Paul's age is equal, we can write:
2x + 4 = 3x + (-1)
Thus, the required expression is
2x + 4 = 3x + (-1)Option D)
Option D! 2x + 4 = 3x + (-1)The equation can be used to determine Kim’s age will be 2x + 4 = 3x + (–1). Then the correct option is D.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Use the information to write an equation with variables on both sides. Let x represent Kim’s age.
Bob is 4 years older than twice Kim’s age. Then the age of the Bob will be in terms of x.
B = 2x + 4
Paul is 1 year younger than 3 times Kim's age. Then the age of the Paul will be in terms of x.
P = 3x – 1
Bob and Paul are the same age.
B = P
Put the value of B and P, then we have the equation will be
2x + 4 = 3x – 1
2x + 4 = 3x + (–1)
Then the correct option is D.
