Answer:

The equation of the line in point-slope form is y - 2 = -4(x + 5).

Step-by-step explanation:

Use the point-slope equation: [tex]y-y_1=m(x-x_1)[/tex].

Substitute the point (-5, 2) and the slope m = -4 into the equation.

If we stop here, this is the equation of the line in point-slope form.

The function f(x) is a sine graph, and the function with the greatest maximum range value is the function f(x)

From the complete question (see attachment), the functions are given as:

Functions f(x) and g(x)

The maximum range value of these functions is their maximum output value

Function f(x) has a maximum range value of 3, while function g(x) has a maximum range value of -2

3 is greater than -2

Hence, the function with the greatest maximum range value is the function f(x)

Answer: Choice C

7*r+7*4-3

=========================================================

Reason:

We use the distributive property to go from 7(r+4) to 7*r+7*4

Multiply the outer 7 by each term inside.

Then the -3 tags along without any changes to it

So we go from 7(r+4) - 3 to 7*r+7*4 - 3

This can be simplified further to 7r+25, but your teacher has chosen not to simplify at this time.

Answer:

112 degrees

Step-by-step explanation:

180-68=112

Since they are supplementary they form a straight angle, or 180 degrees so the angle AED is 112

Answer:

112

Step-by-step explanation:

∠AED and 68 are Linear pair angles.

That is their sum will be equal to 180,

∠AED + 68 = 180

∠AED = 180 - 68

∠AED = 112

Answer:

1716

Step-by-step explanation:

The first choice would be 1 of 13
The second choice would be 1 of 12 (it can't be the same as the first number since they don't repeat)
The third choice would be 1 of 11 (again, can't use the same number more than once)

That gives you 13*12*11=1716

The number of ways we can choose three different numbers in order for a unique code for this case is 2730.

In mathematics, a combination is a selection of items from a set that has distinct members, such that the order of selection does not matter.

here, we have,

We can use combinations for this case,

Total number of distinguishable things is m.

Out of those m things, k things are to be chosen such that their order doesn't matter.

This can be done in total of mCk ways.

If the order matters, then each of those choice of k distinct items would be permuted k! times.

So, total number of choices in that case would be:

mPk = m! / (m - k)!

This is called permutation of k items chosen out of m items (all distinct).

Given that:

The considered lock as a 3 number code

There are 15 numbers available.

None of the number can repeat.

In a lock, the order of the way numbers are arranged matters.

Because of no repetition allowed, we can simulate this situation as:

The number of ways we can choose 3 numbers out of 15 numbers with order = The number of different ways we can choose three different numbers in order for a unique code.

And we have:

The number of ways we can choose 3 numbers out of 15 numbers with order = 15P3 = 2730

Thus, the number of ways we can choose three different numbers in order for a unique code for this case is 2730

If  the confidence interval is 95%, the maximum number of employees who could have agreed is about  is 144.

First step

Confidence interval=(Population±Margin of error)

Confidence interval=(0.65±0.0675)

Confidence interval=(0.65-0.0675); (0.65+0.0675)

Confidence interval=0.5825; 0.7175

Second step

Maximum number= 0.7175×200

Maximum number=143.5

Maximum number=144 (Approximately)

Therefore the maximum number of employees who could have agreed is about  is 144.

Step-by-step explanation:

The area of the smallest circle with radius 3 is 28.27 unit². The area of the yellow ring and white ring is 28.27 unit² and 56.55 unit².

The area of the circle is the space occupied by it. It can be given as,

[tex]A=\pi r^2[/tex]

Here (r) is the radius of the circle.

In this diagram, three concentric circles' rectangle.

The radius of the smallest circle is 3.

[tex]r_1=3\rm\unit[/tex]

Thus, the area of it is,

[tex]A=\pi (3)^2\\A=28.27\rm\; unit^2[/tex]

Let suppose the mid-point of the rectangle is D. Here, OB is the diagonal of the rectangle in which,

[tex]OD=BD[/tex]  

The radius of the yellow ring's outer face from point O is,

[tex]r_3=OD+BD\\r_3=OD+OD\\r_3=2OD\\[/tex]

OD is the radius of the small circle, which is 3 units long. Thus,

[tex]r_3=2\times3\\r_3=6\rm\; units[/tex]

The line segment OC is the radius of the white circle from point O. In the triangle COB from the Pythagoras theorem, the radius r₂ of the middle circle is,

[tex]r_2=\sqrt{r_3^2-r_1^2}\\r_2=\sqrt{6^2-3^2}\\r_2=3\sqrt3[/tex]

Thus, the area of the yellow ring is,

[tex]A_y=\pi r_3^2-\pi r_2^2\\A_y=\pi (6)^2-\pi (3\sqrt{3})^2\\A_y=28.27\rm\; unit^2[/tex]

The area of white ring is,

[tex]A_w=\pi r_2^2-\pi r_1^2\\A_w=\pi (3\sqrt{3})^2-\pi (3)^2\\A_w=56.55\rm\; unit^2[/tex]

Hence, the area of the smallest circle with radius 3 is 28.27 unit². The area of the yellow ring and white ring is 28.27 unit² and 56.55 unit².

Solution: x = 5; The slope is undefined.

The slope that is perpendicular to the x-axis is undefined.

Explanation:

Given point: (5,2)

Since the line is perpendicular to the x-axis, then, the line is vertical.

Hence, x = 5

Answer:

x = 5, the slope is undefined

Step-by-step explanation:

Hello!

To be perpendicular to the x-axis, the line has to intersect at a 90° angle, causing it to be a vertical line with an undefined slope.

This removes the two middle options, as they have a slope of 0.

Consequently, looking at the two options, y=2, and x=5, y=2 would give us a parallel line to the x-axis, as we are drawing a line through all points with a y-coordinate of 2.

The correct option is x=5.

Step-by-step explanation:

The intersection is when both functions have same coordinates

Substitute to get

The y- coordinate is

So the intersection point is (1, 14)

Answer:

(1, 14)

Step-by-step explanation:

Given functions:

[tex]\begin{cases}f(x)=-2x+16\\g(x)=4x+10\end{cases}[/tex]

Substitute the function notation for y to create a system of equations:

[tex]\begin{cases}y=-2x+16\\y=4x+10\end{cases}[/tex]

To find the points of intersection of the given functions, solve the system of equations.

Multiply the first equation (function f(x)) by 2:

[tex]\implies 2y=-4x+32[/tex]

Add this to the second equation (function g(x)) to eliminate x:

[tex]\begin{array}{r l}4x+10 & = y\\+ \quad -4x+32 & = 2y\\\cline{1-2} 42 & = 3y\end{array}[/tex]

Solve for y:

[tex]\implies 3y=42[/tex]

[tex]\implies y=14[/tex]

Substitute the found value of y into one of the equations and solve for x:

[tex]\implies 4x+10=14[/tex]

[tex]\implies 4x=4[/tex]

[tex]\implies x=1[/tex]

Therefore, the point of intersection of the given functions is (1, 14).
