Answer:
A. Inside the circle
Step-by-step explanation:
K(0, 0), U (6, - 4), V (\( \sqrt 2,\: 7)\)
In order to determine whether point V lie inside, outside or on the circle, first we will find the distances between points K & U and then K & V.
KU would be radius of the circle.
If KV is smaller than KU, then V will lie inside. If KV is larger than KU, then V will lie outside And If KV = KU, then V will lie ion the circle.\(d(KU) = \sqrt{ {(6 - 0)}^{2} + {( - 4 - 0)}^{2} } \\ = \sqrt{ {6}^{2} + {( - 4)}^{2} } \\ = \sqrt{36 + 16} \\ \red{ \bold{ d(KU)= \sqrt{52} }} \\ \\ d(KV) = \sqrt{ {( \sqrt{2} - 0)}^{2} + {( 7 - 0)}^{2} } \\ = \sqrt{ {( \sqrt{2)} }^{2} + {(7)}^{2} } \\ = \sqrt{2 + 49} \\ \purple{ \bold{ d(KV)= \sqrt{51} }} \\ \\ \because \: d(KU) > d(KV) \\ \)
Hence point V lie inside of the circle.

a) The inequality into slope- intercept form, and then change it into an equation is y = x + 3. b) y-values are 2, 3, and 4
How to find the slope of an inequalitya. To change the inequality into slope-intercept form, we can first isolate y on one side of the inequality:
y > x - 3
y + 3 > x
Now we can switch the order and write it in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept:
x > y - 3
y - 3 < x
y < x + 3
y = x + 3
b. To create a table using the x-values indicated, we can substitute each value into the equation y = x + 3 and solve for y:
I x y
1 -1 2
2 0 3
3 1 4
So the table would have the x-values -1, 0, and 1 in the first column, and the corresponding y-values 2, 3, and 4 in the second column.

A sequence of transformations occurred to create the two similar polygons. Provide a specific set of steps that can be used to create the image from the pre-image with one, two, or three transformations.
Answer:
Step-by-step explanation:
To create a similar polygon from a pre-image, you can use one or more of the following transformations:
Scaling: Multiply the coordinates of each vertex of the pre-image by a scale factor to obtain the corresponding vertices of the similar polygon. This will change the size of the polygon but not its shape.
Translation: Move the pre-image by adding a fixed value to each coordinate of every vertex. This will shift the polygon horizontally and/or vertically.
Rotation: Rotate the pre-image by a certain angle around a fixed point. This will change the orientation of the polygon.
Here are some specific steps you can follow to create a similar polygon from a pre-image using one, two, or three of these transformations:
One transformation:
Scaling: Choose a scale factor and multiply the coordinates of each vertex of the pre-image by this factor.
Two transformations:
Scaling: Choose a scale factor and multiply the coordinates of each vertex of the pre-image by this factor.
Translation: Choose a vector and add this vector to each coordinate of every vertex of the scaled pre-image.
Three transformations:
Scaling: Choose a scale factor and multiply the coordinates of each vertex of the pre-image by this factor.
Rotation: Choose an angle and a fixed point, and rotate the scaled pre-image around this point by the chosen angle.
Translation: Choose a vector and add this vector to each coordinate of every vertex of the rotated pre-image.
Note that the order of the transformations matters. In general, scaling should be done first, followed by rotation, and then translation.

let r be the region in the first quadrant bounded by the graph of y=2tan(x5), the line y=5−x, and the y-axis. what is the volume of the solid generated when r is revolved about the line y=6
The volume of the solid is 29.865 cubic units.
We have,
To find the volume of the solid generated by revolving region R around the line y = 6, we can use the method of cylindrical shells.
The volume of the solid can be obtained by integrating the area of each cylindrical shell.
Each shell is formed by taking a thin vertical strip of width dx from region R and rotating it around the line y = 6.
Let's denote the radius of each cylindrical shell as r(x), where r(x) is the distance from the line y = 6 to the curve y = 2tan(\(x^5\)).
Since the shell is formed by revolving the strip around y = 6, the radius of the shell is given by r(x) = 6 - 2tan(\(x^5\)).
The height of each cylindrical shell is the difference in x-values between the curve y = 5 - x and the y-axis, which is given by h(x) = x.
The differential volume of each cylindrical shell is given by:
dV = 2π x r(x) x h(x) x dx.
To find the total volume of the solid, we integrate the differential volume over the interval where region R exists, which is determined by the intersection of the curves y = 2tan(\(x^5\)) and y = 5 - x.
The volume V is given by the integral:
V = ∫[a,b] 2π x (6 - 2tan(\(x^5\))) x dx
Setting the two equations equal to each other, we have:
2tan(\(x^5\)) = 5 -x
Let's use numerical approximation to find the intersection points.
Using a numerical solver, we find that one intersection point is approximately x ≈ 1.051.
Now, we can set up the integral to find the volume of the solid:
V = ∫[a,b] 2π (6 - 2tan(\(x^5\))) x dx
Since we are revolving around the line y = 6, the limits of integration will be from x = 0 to x = 1.051.
V = ∫[0,1.051] 2π (6 - 2tan(\(x^5\))) x dx
The integral does not have an elementary antiderivative, so we cannot find the exact value of the integral.
However, we can still approximate the value using numerical methods or software.
Using numerical approximation methods, the volume is approximately V ≈ 29.865 cubic units.
Thus,
The volume of the solid is 29.865 cubic units.

What are lines and their slopes?An equation of a line in slope-intercept form is y = mx + b.
Where slope = m and b = y-intercept.
The slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
From, The given graph the pair of coordinate points can be,

the lifetime of a certain electronic component is a random variable with the expectation of 5000 hours and a standard deviation of 100 hours. what is the probability that the average lifetime of 400 components is less than 5012 hours?
The probability that the average lifetime of 400 components is less than 5012 hours is approximately 89.15%.
To find the probability that the average lifetime of 400 components is less than 5012 hours, we need to calculate the z-score and find the corresponding probability from the standard normal distribution.
The formula to calculate the z-score is:
z = (x - μ) / (σ / sqrt(n)) ,
where x is the given value (5012 hours), μ is the population mean (5000 hours), σ is the population standard deviation (100 hours), and n is the sample size (400 components).
Substituting the given values into the formula:
z = (5012 - 5000) / (100 / sqrt(400))
z = 12 / (100 / 20)
z = 12 / 5
Using a standard normal distribution table or a calculator, we can find the probability corresponding to the z-score of 12/5. Looking up the z-score of 12/5 in a standard normal distribution table, we find that the probability is approximately 0.8915.
