The scatterplot shows a linear relationship between left and right forearm lengths in cm, for 55 college students.

The regression line is the best fit line that describes the relationship between the two variables. The formula for a linear regression line is  y = mx + b, where m is the slope of the line and b is the y-intercept. The slope of the line in the scatterplot is 0.95, which indicates that for every 1 cm increase in the left arm, there is a 0.95 cm increase in the right arm. The y-intercept of the regression line is 8.4, meaning that when the left arm is 0, the right arm is 8.4 cm long. The equation for the regression line in the scatterplot is y = 0.95x + 8.4. This equation can be used to predict the right arm length for any given left arm length.

-√12 i is the complex conjugate of the complex number√-12

A complex number is an element of a number system that extends the real numbers with a specific element denoted i, called the imaginary unit.

A conjugate of a complex number is another complex number which has the same real part as the original complex number and the imaginary part has the same magnitude but opposite sign.

It's important to remember that i²=-1

This means we can rewrite

√-12 as √12i² =√12i

For complex number z=x+iy the conjugate of complex number is z=x-iy

Jorge's water bottle holds 2 2/5 liters of water, which can be written as 22/5 liters or 4.4 liters.

Jorge's estimate of his water bottle holding about 1/2 liter more water than Carmen's is reasonable because:

4.4 liters (Jorge's bottle) - 1.8 liters (Carmen's bottle) = 2.6 liters

2.6 liters is close to the estimate of 1/2 liter, so Jorge's estimate is reasonable.

Answer:64 PI

Step-by-step explanation:

The final solution for the initial value problem: y = −e∫x dx√40 − ∫x2e∫x dx − ∫y2e∫x dx.

The given initial value problem is yy′+x=x2+y2 with y(3) = −√40. To solve this we make the substitution U = u' and u = y. This transforms the given equation into the linear differential equation in x, u, and u': u'+xu=x2+u2. To solve this, we can use the integrating factor method. Multiplying both sides by the integrating factor e∫x dx gives us u'e∫x dx + xue∫x dx = x2e∫x dx + u2e∫x dx. Taking the integral of both sides, we obtain ue∫x dx = ∫x2e∫x dx + ∫u2e∫x dx + c, where c is the constant of integration. Solving for u, we have u = c/e∫x dx − ∫x2e∫x dx − ∫u2e∫x dx. Using the fact that u = y, we can substitute this expression into the equation to obtain the solution in terms of x and y: y = (c/e∫x dx) − ∫x2e∫x dx − ∫y2e∫x dx. Using the initial condition y(3) = −√40, we can solve for c to get c = −e∫3 dx√40. Substituting this into the solution, we get the final solution for the initial value problem: y = −e∫x dx√40 − ∫x2e∫x dx − ∫y2e∫x dx.

Consider the simple given arrangement of three resistors, the total equivalent resistance of the arrangement will be smaller than the resistor C.

Please refer to the attached picture below for the give resistors arrangement.

The three resistors are arranged in a paralel circuit. Hence, the total equivalent resistance for the arrangement will be:

1/R total = 1/Ra + 1/Rb + 1/Rc

Where:

Ra = A

Rb = b

Rc = C

A < B < C

Then, the total resistance will be:

1/R total = 1/A + 1/B + 1/C

    1       = BC + AC + AB

R total              ABC

R total =           ABC      

                BC + AC + AB

Next, we will try to choose any random numbers that meet the resistors condition to proof this condition. This time, we choose:

A = 3

B = 2

C = 1

Then, we need to subtitute each number to its positions:

R total =          3 x 2 x 1

The slope of the line is 1/3.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.

Slope of a line passing through (x, y) and (x', y') is given by,

Slope = (y' - y) / (x' - x)

Consider the points on the given line.

The line passes through (0, 2) and (3, 3).

The cost per square inches of the circular pie is C = $ 0.164

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

Given data ,

Let the cost per square inch of the apple pie be C

Let the area of the circle be represented as A

Now , the diameter of the circle is d = 10 inches

So , the radius of the circle r = d/2 = 5 inches

And , area of the circle = πr²

Substituting the values in the equation , we get

Area of Circle A = π x ( 5 )²

Area of Circle A = 78.5398 inches²

The cost of the apple pie = $ 12.85

Now , the cost for 78.5398 inches² of apple pie = $ 12.85

So , the cost for 1 inches² of pie C = 12.85 / 78.5398

On simplifying the equation , we get
