At Which values of x does the function f(x) have a vertical asymptote? Check all that apply
Answer:
C, D and E
Step-by-step explanation:
The denominator of f(x) cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the values that x cannot be and if the numerator is non zero for these values then they are vertical asymptotes.
solve 3x(x - 1)(x + 5) = 0
Equate each factor to zero and solve for x
3x = 0 ⇒ x = 0
x - 1 = 0 ⇒ x = 1
x + 5 = 0 ⇒ x = - 5

Step-by-step explanation:
Under a counterclockwise rotation about the origin of 180°
a point (x, y ) → (- x, - y) → C
Answer: C) (x, y) → (−x, −y)
Step-by-step explanation:
When we rotate a figure 180°clockwise or counter-clockwise , the magnitude of x and y coordinates remains same but their signs got changed.
For example : After a rotation of 180°clockwise or counter-clockwise (3,4) becomes (-3,-4).
Algebraically , we can say
Ordered pair (x , y ) will become (-x, -y) after a rotation of 180°clockwise or counter-clockwise.
Thus , the algebraic rule describes the 180° counter-clockwise rotation about the origin will be :-

Use the four-step process to find f'(x) and then find f'(1), f'(2), and f'(3).
f(x) = -x^2+6x-5
f'(x) =
Step 1: evaluate f(x+h) and f(x)
We have
[tex]f(x+h) = -(x+h)^2+6(x+h)-5 = -(x^2+2xh+h^2)+6x+6h-5[/tex]
[tex]= -x^2-2xh-h^2+6x+6h-5[/tex]
And, of course,
[tex]f(x)=-x^2+6x-5[/tex]
Step 2: evaluate f(x+h)-f(x)
[tex]f(x+h)-f(x)=-x^2-2xh-h^2+6x+6h-5-(-x^2+6x-5)=-2xh-h^2+6h[/tex]
Step 3: evaluate (f(x+h)-f(x))/h
[tex]\dfrac{f(x+h)-f(x)}{h}=-2x-h+6[/tex]
Step 4: evaluate the limit of step 3 as h->0
[tex]f'(x) = \displaystyle \lim_{h\to 0} \dfrac{f(x+h)-f(x)}{h}=-2x+6[/tex]
So, we have
[tex]f'(1) = -2\cdot 1+6 = 4,\quad f'(2) = -2\cdot 2+6 = 2,\quad f'(3) = -2\cdot 3+6 = 0[/tex]

Find the value of a-b+c+d 2x+8y=7 4x-2y=9
Answer:
The value of a - b + c + d = -4
Step-by-step explanation:
* Lets explain the linear equation
- The linear equation is the equation that represented graphically
by a line
- The general form of its equation is ax + by = c
- The slope of the line is -a/b and the y-intercept of the line is c/a,
where a is the coefficient of x , b is the coefficient of y and c is the
numerical term
∵ We have two linear equation in the problem
∴ Their general form is ax + by = e , cx + dy = f
∵ The equation are 2x + 8y = 7 and 4x - 2y = 9
- By comparing the two equations with their general forms
∴ a = 2 , b = 8 , c = 4 , d = -2
- Now we can find the value of a - b + c + d
∵ a = 2 , b = 8 , c = 4 , d = -2
∴ a - b + c + d = 2 - 8 + 4 + (-2) = 2 - 8 + 4 - 2 = -4
* The value of a - b + c + d = -4

A triangular brace has an angle measure of 30 degrees, with a side opposite this angle measuring 8 inches. The base of the triangular brace, which is adjacent to the given angle measure, is 11 inches in length. Which of the following statements is correct?
The problem can be solved using trigonometric principles where the hypotenuse measures 16 inches.
Explanation:The problem involving a triangular brace can be solved using trigonometry principles. As it involves a right triangle, you can use the sine function to solve the problem. In a right triangle, the sine of an angle (hypotenuse) is the length of the side opposite the angle divided by the length of the hypotenuse.
In this case, you have the opposite side (8 inches), the angle (30 degrees), and the adjacent side (base, 11 inches). Using these values and the sine rule, we can determine the length of the hypotenuse. In a 30-degree angle, the sine is 0.5, so the unknown length can be obtained by dividing the length of the opposite side by the sine of the angle. This gives: 8/0.5 = 16 inches.
Therefore, the correct statement will be that the hypotenuse of the triangular brace is 16 inches.

Using the principles of trigonometry, specifically the sin and cos functions, applied to a triangle with a 30 degrees angle and known lengths of the sides opposite and adjacent to this angle, we can calculate the length of the hypotenuse.
Explanation:The question asked pertains to the principles of trigonometry. In particular, we have a triangle with one angle of 30 degrees, and we know the lengths of the side opposite this angle (8 inches) and the base of the triangle, which is adjacent to this angle (11 inches).
With a 30 degree angle, we can use sin, cos, and tan functions to form relationships with the opposite, adjacent, and hypotenuse sides of the triangle. In this scenario, the sin(30 degrees) = opposite length/hypotenuse = 8 inches/hypotenuse. Alternatively, the cos(30 degrees) = adjacent length/hypotenuse = 11 inches/hypotenuse.
To solve for the hypotenuse using the sin, you'd do 8/sin(30 degrees). From the cos, you'd do 11/cos(30 degrees).
Note that while you have two ways to solve for the hypotenuse, these should give you the same answer if your angle and side lengths are correct.

Step-by-step explanation:
Solve (X + 6)(x - 4) = -16
O {-4, 6)
O {-4, 2]
O (-12, 22)
Final answer:
To solve the equation (x + 6)(x - 4) = -16, expand the brackets, rearrange the equation, and factorize to find the solutions.
Explanation:
To solve the equation (x + 6)(x - 4) = -16, we can start by expanding the brackets:
x2 - 4x + 6x - 24 = -16
x2 + 2x - 24 = -16
Next, we can rearrange the equation to one side:
x2 + 2x - 24 + 16 = 0
x2 + 2x - 8 = 0
Finally, we can factorize the quadratic equation:
(x + 4)(x - 2) = 0
This gives us two possible values for x: x = -4 or x = 2.
Which statement accurately describes how to perform a 90° clockwise rotation of point A (1,4) around the origin?
I was expecting a choice that said A(1,4) is in the first quadrant so 90 degrees clockwise is fourth quadrant. For perpendicularity we reverse the coordinates, negating one of them. For the fourth quadrant, it must be the y coordinate that's negative. We end up at A'(4,-1).
The answer is the second choice: create a circle with the center at the origin. The image of A' will be on the circle, 90 degrees clockwise from A.
Solve for x.
5(х – 10) = 30 — 15х
x = 1
x = 4
х = 5
х = 8
In order to solve for x, we must do the following:
5(x - 10) = 30 - 15x
5x - 50 = 30 - 15x (Expand 5(x - 10) )
5x - 50 + 50 = 30 - 15x + 50 (Add 50 to both sides of the equation)
5x = 80 - 15x
5x + 15x = 80 - 15x + 15x (Add 15x to both sides)
20x = 80
20x/20 = 80/20 (Divide both sides by 20)
x = 4
Therefor, the correct answer is the second option (x = 4).
You can always check if this is correct by substituting your answer back into the original equation and seeing if the left side is equal to the right side (this is also a potential method for solving the question itself if it is multiple choice, but I find it is often better to actually solve the equation rather than substitute each answer to see which works):
5(x - 10) = 30 - 15x
if x = 4:
5(4 - 10) = 30 - 15(4)
5(-6) = 30 - 60
-30 = -30
The two sides are equal, therefor x = 4 is confirmed as the correct answer.
Final answer:
To solve the equation 5(x - 10) = 30 - 15x, we expand and rearrange to get 20x = 80 and divide both sides by 20 to find that x = 4.
Explanation:
The student is asking us to solve for x given the equation 5(x – 10) = 30 – 15x.
To solve for x, we first expand the left side of the equation:
5x - 50 = 30 - 15x. Next, we collect like terms by adding 15x to both sides and adding 50 to both sides to isolate x:
5x + 15x = 30 + 50.
This simplifies to:
20x = 80.
We then divide both sides by 20 to solve for x:
x = 80 / 20.
This results in:
x = 4. Therefore, x equals 4 is the solution.
As a check, substituting x = 4 back into the original equation yields the identity 5(4 - 10) = 30 - 15(4), or -30 = -30, confirming that x = 4 is indeed the correct solution.

Answer:
cos 2Ф = - 161/289 , tan 2Ф = - 240/161
Step-by-step explanation:
* Lets explain how to solve the problem
∵ cos Ф = - 8/17
∵ Ф lies in the 3rd quadrant
- In the 3rd quadrant sin and cos are negative values, but tan is
a positive value
∵ sin²Ф + cos²Ф = 1
∴ sin²Ф + (-8/17)² = 1
∴ sin²Ф + 64/289 = 1
- Subtract 64/289 from both sides
∴ sin²Ф = 225/289 ⇒ take √ for both sides
∴ sin Ф = ± 15/17
∵ Ф lies in the 3rd quadrant
∴ sin Ф = -15/17
∵ cos 2Ф = 2cos²Ф - 1 ⇒ the rule of the double angle
∵ cos Ф = - 8/17
∴ cos 2Ф = 2(-8/17)² - 1 = (128/289) - 1 = - 161/289
* cos 2Ф = - 161/289
∵ tan 2Ф = sin 2Ф/cos 2Ф
∵ sin 2Ф = 2 sin Ф × cos Ф
∵ sin Ф = - 15/17 and cos Ф = - 8/17
∴ sin 2Ф = 2 × (-15/17) × (-8/17) = 240/289
∵ cos 2Ф = - 161/289
∴ tan 2Ф = (240/289)/(-161/289) = - 240/161
* tan 2Ф = - 240/161
