Answer:

(-6, 3)

Step-by-step explanation:

If you rotate the coordinates, (2, -3), 90° clockwise around the point, (1, 4), then it will become Point P' at (-6, 3). There isn't a very efficient way to explain this but since Point P is 7 units south and 1 unit east of (1, 4) we need to keep it the same distances away when we turn it 90°. You can use something like parchment paper, record the point you're turning it around, (1, 4), and the point to be turned, Point P at (2, -3). If you rotate it exactly 90° without ever moving the point on (1, 4), Point P should now be at (-6, 3) if that makes sense.

The rate at which the distance from the plane to the station is increasing when it has a total distance of 4 miles away from the station is 317.5 mi/h.

A rate in which a certain number of units of the first quantity are compared to one unit of the second quantity is not the same as a unit rate. In other words, we may state that the comparison's second amount is always 1.

Thus, P denotes the plane's location, R denotes the radar's location, and V denotes the point that is vertical to the radar and at the plane's height.

Assume that h is the height of the plane, s is the separation from the radar, and x is the separation from point V.

The plane travels at 480 miles per hour and has a 3 mile height. Ds-480 miles per hour.

dt By Pythagorean theorem,

x² = h² + s²

x² = 3²+s²

x² = 9 + s²

Differentiate implicitly with respect to t.

2x dx/dt = 2s ds/dt + 0

x dx/dt = s ds/dt

Use (1)

dx/dt = \(\frac{dx}{dt} =\frac{\sqrt{x^2-9} }{x}\)

= √7/4 x 480

= 120√7

≈ 317.49

Hence, the distance increasing at the rate of dx/dt is 317.5 mi/h.

{ Equation }

y=16/x² is required equation for y in terms of x and x=4/5 when y=25.

Two or more expressions with an Equal sign is called as Equation.

The table of values are

x         1         2         3         4

y        16        4        16/9      1

Given that y is inversely proportional to square of x.

y=k/x²

Let us consider

y=16 and x=1

16=k/1

k=16.

y=16/x²

So y=16/x² is equation for y in terms of x

b) We need to find value of x when y=25

25=16/x²

Use cross multiplication

x²=16/25

Take square root on both sides

√x²=√16/25

x=±4/5

The piecewise function graphed in this problem is given as follows:

C) y = x² + 2, x < 1, y = -x + 2, x ≥ 1.

A piece-wise function is a function that has different definitions, depending on the input of the function.

To the left of x = 1 in this problem, we have the quadratic function with vertex at (0,2), hence it is given as follows:

y = x² + 2, x < 1.

To the right of x = 1, including x = 1, we have a linear function with slope of -1 and intercept of 2, hence it is given as follows:

y = -x + 2, x ≥ 1.

\(20\frac{ 3}{7}\)  is the circumference of a circular swimming pool with a diameter of 6 1/2 ft.

Circumference of a circle is πd,  where d is the diameter

From the question

d = 6½ feet = 13/2 feet

Circumference is

π × 13/2

= 22/7 × 13/2

= 143/7

= \(20\frac{3}{7}\)

What's the circumference?

The meaning of circumference is the distance around a circle or any twisted geometrical shape. It's the one- dimensional direct dimension of the boundary across any two- dimensional indirect face. In figure, the circumference( from Latin circumferens, meaning" carrying around") is the border of a circle or cirque. That is, the circumference would be the bow length of the circle, as if it were opened up and uncurled out to a line member.

Answer:

let the numbers be, x and x+1 ( as it is consecutive number the next number will have 1 more than the number )

sum = 41

so, x + ( x + 1 ) = 41

      x + x + 1 = 41

        2x + 1 = 41

             2x = 41 -1 = 40

              2x = 40

                x = 40/2 = 20

x = 20

x + 1 = 20 + 1 = 21

The reflection of shape A in the line y = x can be sketched as shown in the attached image.

Transformations are used to describe changes in geometric figures. Reflection is a transformation that mirrors an object across a line or a plane called the line of reflection or the mirror line.

Each point of the object is reflected across the line, resulting in a flipped image.

When a point with coordinate (x, y) is reflected in the line y = x, the coordinate of the image is (y, x).

From the picture, the coordinate of shape A are:

(1, -2)

(4, -2)

(1, -4)

(3, -4)

(3, -3)

(4, -3)

Thus, when reflected in the line y = x, the coordinate of shape A are:

(-2, 1)

(-2, 4)

(-4, 1)

(-4, 3)

(-3, 3)

(-3, 4)

Therefore, the reflection can be sketched as shown in the attached image.

The composite method for determining the location of the center of gravity of a composite body requires integration.

So, the answer is A.

The center of gravity is the point at which the entire weight of a body appears to act when the body is in equilibrium.

The concept of a center of gravity is used to calculate the behavior of a body when subjected to external forces. The composite method for determining the location of the center of gravity of a composite body involves integration.

The center of gravity is found by dividing the sum of the products of individual masses with their corresponding distance from an arbitrary reference line by the total mass of the system. When there is more than one weight distribution involved, the composite method is employed.

The equation of the tangent line to the curve `y = 2ex cos(x)` at the point (0,2) is given by `y = 2ex + 2`.

To find an equation of the tangent line to the curve at the given point (0,2) whose equation is given by `y = 2ex cos(x)`, we need to determine the derivative `y'` of `y = 2ex cos(x)` first. Using the product rule, we have;

`y = 2ex cos(x)`...let `u = 2ex` and `v = cos(x)`, then `u' = 2ex` and `v' = -sin(x)`.`y' = u'v + uv'` `= 2ex cos(x) - 2ex sin(x)` `= 2ex(cos(x) - sin(x))`

Therefore, the derivative of `y = 2ex cos(x)` is `y' = 2ex(cos(x) - sin(x))`.

The equation of the tangent line to the curve at the point (0,2) is obtained by using the point-slope formula, which is given by: `y - y1 = m(x - x1)`where `(x1,y1)` is the point of tangency, `m` is the slope of the tangent line.

Substituting the values of `m`, `x1` and `y1`, we obtain: `m = y' |(0,2)` `= 2e(1 - 0)` `= 2e`Using the point-slope formula with `(x1,y1) = (0,2)` and `m = 2e`, we have: `y - 2 = 2e(x - 0)` `y - 2 = 2ex` `y = 2ex + 2`

The correct answer is: Yes, because 12a(a + b) is a multiple of 6a.

To see why, we can simplify the expression 12a(a + b) by factoring out the common factor of 6a:

12a(a + b) = 6a(2a+2b) = 6a(2(a + b))

When we factor out 6a from 12a(a + b), we get 6a(2(a + b)). This means that 6a is a divisor of 12a(a+b), making it a multiple of 6a.

Additionally, since all variables represent integers, we can be sure that 2a+2b is also an integer. Therefore, 6a(2a+2b) is an integer because it is a product of two integers. Thus, the original expression, 12a(a + b), is a multiple of 6a.. Therefore, the statement is true.

It's important to note that the other answer choices are not correct. While it is true that 12a(a + b) can be written as 6a(2(a + b)), this fact alone does not necessarily imply that it is a multiple of 6a. Similarly, while 6 is a factor of 12, this fact alone does not help us determine whether 12a(a + b) is a multiple of 6a. Finally, the fact that 12a(a + b) can be written as 6a multiplied by an integer does not depend on whether 6 is a divisor of 12.

As X and Y are two numerical variables. Because they are independent so there is no relationship between the two variables other than the linear relationship described by the regression equation. The correct answer is B. III only, that is  X and Yare independent.

When performing a regression analysis involving two numerical variables, we assume that X and Y are independent, meaning that the value of one variable does not depend on the value of the other variable. However, we do not assume that the variances of X and Y are equal or that the variation around the line of regression is the same for each X value. These assumptions are not necessary for performing a regression analysis. Violation of this assumption can lead to spurious results and incorrect inferences. So, the correct option in  B. III only.
