Step-by-step explanation:

From the given picture, we can that the coordinates of point C and D are (5,4) and (4,2).

After dilation with scale factor of 8 with the origin as the center of dilation , the coordinates of C' and D' will be :-

[tex]C'=(8\times5,8\times4)=(40,32)[/tex]

[tex]D'=(8\times4,8\times2)=(32,16)[/tex]

Now, the slope of line segment C'D' will be

[tex]\text{Slope}=\dfrac{\text{Change in y-coordinate}}{\text{Changein x-coordinate}}\\\\\Rightarrow\text{Slope}=\dfrac{16-32}{32-40}\\\\\Rightarrow\text{Slope}=\dfrac{-16}{-8}\\\\\Rightarrow\text{Slope}=2[/tex]

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

Vertical asymptotes at x = -5, x = 1 and x = 0

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

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.

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

Step-by-step answer:

Area of a kite is half of the product of the diagonals.

The length of diagonal in the x-direction is 4+5 = 9

The length of diagonal in the y-direction is 4+4 = 8

Therefore

Area of kite = 8*9/2 = 36 units.

ANSWER

The correct answer is A.

EXPLANATION

If you know the diagonals of a kite you can easily find the area.

The area of a kite is half the product of the diagonals.

From the graph, the from -5 to 4.

Using the number line approach. The longer diagonal is

[tex] |4 - - 5| = |4 + 5| = |9| = 9 \: \: units[/tex]

Similarly the shorter diagonal is from -4 to 4

[tex] |4 - - 4| = |4 + 4| = |8| = 8 \: \: units[/tex]

The area of the kite is:

[tex]Area= \frac{1}{2} \times 8 \times 9[/tex]

[tex]Area=4 \times 9[/tex]

This implies that

[tex]Area=36 \: square \: \: units[/tex]

X - intercept is the point where the graph crosses the x-axis

in this case, the graph crosses at x = 2 and y = 0; or (2,0)

Answer:

(2, 0)

Step-by-step explanation:

The x- intercept is where the line crosses the x- axis at x = 2

x- intercept is (2, 0)

The y- intercept is where the line crosses the y- axis at y = - 4

y- intercept is (0, - 4)

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]

Answer:

Hi there!

The answer is A, and C

Step-by-step explanation:

cos(-x)=cos(x)

sec(-x)=sec(x)

Answer:

A and C.

Step-by-step explanation:

Graphs that have symmetry with respect to the y-axis are called even functions. So, let's check each of the graphs:

1. As we can see in the graph attached, y=cos(x) is symmetrical with respecto to the y-axis.

2. As we can see in the graph attached, y=sin(x) is not symmetrical with respecto to the y-axis.

3. As we can see in the graph attached, y=sec(x) is symmetrical with respecto to the y-axis.

4. As we can see in the graph attached, y=csc(x) is not symmetrical with respecto to the y-axis.

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.

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.

arc JL = 2(82)

arc JL = 164°

The measure of JL is 164°.

The correct option is (B)

An arc whose measure is less than 180 degrees is called a minor arc.

Given: angle JKL= 82°

We know by the theorem that

"When two angles are subtended by the same arc, the angle at the centre of a circle is twice the angle at the circumference."

Then,

JL= 2 (JKL)

JL= 2(82)

JL= 164°.

The problem can be solved using trigonometric principles where the hypotenuse measures 16 inches.

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.

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.
