Step-by-step explanation:

The equation for the tangent to the graph of y = arcsin(x/2) at the origin is y = x. This means that for any given x-value, the corresponding y-value is equal to that x-value, creating a line with a slope of 1. This line is tangent to the graph of y = arcsin(x/2) at the origin, which is (0, 0).

To find the equation for the tangent to the graph of y = arcsin(x/2) at the origin, we must first find the slope at the origin. We can do this by taking the derivative of the function y = arcsin(x/2) with respect to x.

The derivative of

y = arcsin(x/2) with respect to x is y' = (1/2)cos(x/2).

At the origin, x = 0, so the slope of the tangent at the origin is

y' = (1/2)cos(0) = 1.

Therefore, the equation for the tangent to the graph of

y = arcsin(x/2) at the origin is y = x, which has a slope of 1.

Only options I and III are (C)'s correct responses.

I. k-fold cross-validation requires fitting the model k times, whereas LOOCV requires fitting the model n times. Since k > n, k-fold cross-validation is more efficient computationally than LOOCV.

II. k-fold cross-validation has an advantage over LOOCV in bias reduction since each training set is a random sample of the data and tends to reduce bias.

III. LOOCV has an advantage over k-fold cross-validation in variance reduction since LOOCV uses almost all the data to fit the model for each test observation, resulting in lower variance in the test error estimate. In contrast, k-fold cross-validation uses only a subset of the data for each training set, which can lead to higher variance in the test error estimate.

In conclusion, assertions I and III are valid, and the proper response is (C) I and III alone.

The width of rectangular driveway is  6 ft while and 28 ft long.

Let's start by defining variables for the length and width of the driveway. We can let "L" represent the length and "W" represent the width.

From the problem statement, we know that the length of the driveway is two feet less than five times the width. This can be written as:

L = 5W - 2

We also know that the area of the driveway is 168 sq. ft. This means:

L x W = 168

Thus, area

(5W - 2) x W = 168

Expanding the parentheses and simplifying, we get:

5W^2 - 2W - 168 = 0

Thus,

W = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 5, b = -2, and c = -168.

Plugging in these values, we get:

W = 6 or W = -5.6

Since the width cannot be negative, we can discard the solution of W = -5.6. Therefore, the width of the driveway is 6 ft.

To find the length, we can plug in W = 6 into the equation we derived earlier:

L = 5W - 2 = 28

So the length of the driveway is 28 ft, and the width is 6 ft. Therefore, the answer is (d) 28 ft long by 6 ft wide.

Your monthly payments with taxes and insurance included would be $2,903.71. This is calculated by taking the loan amount of $450,000 and multiplying it by the simple interest rate of 6.00%. The result is $27,000, which is then divided by the length of the loan, 30 years. This gives you

the principal and interest portion of your monthly payment, which is $2,033.33. To that, you add your yearly taxes of $2,000 and insurance of $1,500, divided by 12 months, to get an additional $416.67 and $125, respectively. Adding these two numbers together gives you your total monthly payment of $2,903.71.

The number of panels that Plant B produced is; 11000 panels

We are told that Plant A produced 4000 fewer panels than Plant B did.

Thus;

A = B - 4000    -----(1)

Four percent of the panels from Plant A and 2% of the panels from Plant B were defective. Thus;

0.04A + 0.02B = 500   ------(2)

Put eq 1 in eq 2 to get;

0.04(B - 4000) + 0.02B = 500

0.04B - 160 + 0.02B = 500

Formula for peak voltage is;

V_p = V_rms × √2

Making V_rms the formula, we have;

V_rms = (V_p)/√2

We are given:Peak voltage: V_p = 50 VAC

The number of ways to pick 6 people from a group of 10 so that the bride and groom must be next to each other is 8!4!4!⋅5!⋅2!

We can reduce your problem to a simpler one, as you claim that the bride must be in the picture. Now you have to select 5 people out of 9.

It's just 9!4!5!

Now it's just a matter of choosing the participants of the picture. Since there are 6 people in the picture, you can arrange 6 of them! ways. This leaves the total number of possible combinations 9!4!5!⋅6!

I would also like to discuss another possible option of 6 people from a group of 10 where 2 of the 6 must be the bride and groom and must be next to each other. I can see it coming in a similar situation.

This has a familiar beginning. We already know 2 of the 6 people, so only 4 left to choose from the remaining 8. This is given by 8!4!4!.

Now we need to permute the group of 6 participants. One would like to say that this is simply a 6! like the first problem, but it's a little different. Remember that the bride and groom must be next to each other. You can basically think of these two people as one person.

So the actual number of ways to permute this group of 6 people with a constraint is 5! . There is one more condition. If you don't subscribe to the opinion that the groom must always be on the left (facing the couple), you have two options to arrange our couple.

The number of ways to pick 6 people from a group of 10 so that the bride and groom must be next to each other is 8!4!4!⋅5!⋅2!

Answer:

When I work with function composition, I usually convert "( f o g)(x)" to the more intuitive " f (g(x))" form. This is not required, but I certainly find it helpful. In this case, I get:

(g o f )(1) = g( f(1))

This means that, working from right to left (or from the inside out), I am plugging x = 1 into f(x), evaluating f(x), and then plugging the result into g(x). I can do the calculations bit by bit, like this: Since f(1) = 2(1) + 3 = 2 + 3 = 5, and since g(5) = –(5)2 + 5 = –25 + 5 = –20, then (g o f )(1) = g( f(1)) = g(5) = –20. Doing the calculations all together (which will be useful later on when we're doing things symbolically), it looks like this:

(g o f )(1) = g( f (1))

  = g(2(   ) + 3)   ... setting up to insert the original input

  = g(2(1) + 3)

  = g(2 + 3)

  = g(5)

  = –(   )2 + 5    ... setting up to insert the new input

  = –(5)2 + 5

  = –25 + 5

  = –20

Note how I wrote each function's rule clearly, leaving open parentheses for where the input (x or whatever) would go. This is a useful technique. Whichever method you use (bit-by-bit or all-in-one), the answer is:

(g o f )(1) = g( f (1)) = –20

I just computed (g o f )(1); the composition can also work in the other order

Step-by-step explanation:

The value of a is 4.

Hence, a = 4

Here,

\(f(x) = (5 - x)^3 and, g(x) = a + x^2,\)

and \(f(g(x)) = (1 - x^{2} )^3\)

We have to find the value of a.

What is composite function?

Function composition is an operation that takes two functions f and g and produces a function h such that h(x) = g(f(x)).

Now,

\(f(x) = (5 - x)^3 and, g(x) = a + x^2,\)

and \(f(g(x)) = (1 - x^{2} )^3\)

⇒ \(f(g(x)) = f ( a + x^{2} )\)

⇒ \(f ( a + x^{2} ) = ( 5 - a - x^{2} )^3\)

And,

\(f(g(x)) = (1 - x^{2} )^3\)

\(( 5 - a - x^{2} )^3 = ( 1 - x^{2} )^3\\\)

Taking cube root both sides,

\(( 5 - a - x^{2} ) = ( 1 - x^{2} )\\ 5 - a - x^{2} = 1 - x^{2} \\a = 4\)

Answer:

200 miles

Step-by-step explanation:

Given data

cost of car rental per day= $40

cost per mile= $0.22

We are told that the budget is $84

The expression for the total cost is given as

y= 40+0.22x

where x = the distance travelled

now for y=$84, by substituting we can get x

84=40+0.22x

84-40=0.22x

44=0.22x

divide both sides by 0.22

x= 44/0.22

x=200

Hence the distance that $84 will go is 200 miles
