Y varies directly as the square of x means:

y = kx^2

Where,

k is the constant of variation. You can use any letter except y or x for constant

Put values of y and x: (24) = k * (4)^2

k = 24/(4*4) = 24/16 = 3/2 = 1.5

Answer: The constant of variation
is 1.5

Don't expect a quilt to be as accurate from a serger as from a sewing machine. First, you probably want to focus a strip quilt where rows of strips are stitched together. If you do strips, you won't have to worry so much about maintaining an exact 1/4" seam. You can also vary the widths of strips in order to camouflage any seam variations. Avoid a pattern that requires points being aligned! Any seam width variances will not as obvious as an error (it is intensive getting an accurate 1/4" on a sewing machine--so-o-o-o much more difficult on a serger). There are usually seam width marks on a serger that you can follow as a guide, but straight line serging is very difficult to accomplish. You can always try marking a line on your serger using painter's tape.

FWIW, making a strip quilt on a serger is a fast way of finishing a quilt. I divide my quilt into 3 or 4 sections, like making it in thirds or fourths. That way, when the quilt begins to grow, you are not constantly grappling with flipping or turning the heavy and bulky fabric. Instead, do each section separately, then stitch the sections together to make the whole quilt.

Also, be sure to press all the seams of a strip quilt in the same direction.

The rate of change for the function y=5x+4 is the coefficient 5 that multiplies the independent variable x. For a unit variation of x (x varies by 1) y varies by 5 units.

Between x1=2 to x2=3, y varies from y1=5*2+4=14 to y2=5*3+4=19.

The rate of change is defined as

**(variation in y)/(variation in x)=(19-14)/(3-2)=5**

Between x1=2 to x2=3, y varies from y1=5*2+4=14 to y2=5*3+4=19.

Linear feet are a measure of length (no different from feet); square feet measure area. You cannot simply convert between measures of different kinds of quantities;the connection between them will be specific to a particular problem.A practical example in which this question can arise is in buying countertops for a kitchen. Some materials are sold by the square foot; others (basically those that are extruded, so they come in standard widths) are sold by the linear foot. In order to compare the two, you need to compute the area and wall length for the countertop you want.You can't convert between the two. All you have to do is to make the appropriate measurements so you can calculate the price of each item.The terms used in the lumber industry are a bit confusing.There are two terms that I think you might be mixing up.A LINEAR FOOT is simply the length of a board. If you want to know the area or volume of the board,you need additional information. For instance, 6 linear feet of 1-by-12 has an area of 6 square feet (12 inches = 1 foot, times 6 feet), and it's 1 inch thick, so the volume is 1/2 cubic foot (6 square feet times 1/12 foot). But 6 linear feet of a 1-by-6 board would have half the area and half the volume.A BOARD FOOT is equivalent to one square foot of a 1-inch-thick board. In other words, it is a square-foot-inch (ft^2-in), or 1/12 cubic foot.Linear feet are used for the pricing of a single size such as two-by-fours. Board feet are used for larger lumber that you are more likely to want to compare directly with different size boards .To sum up, neither a linear foot nor a board foot can be converted directly to square feet. A linear foot is a linear (length) measure, and a board foot is a volume measure. You need to know your particular board to do anything more, such as find the area.an example with an" L" shaped countertop will betwo rectangles are 24 by 80 inches and 24 by 36 inches. Thus the area is: 24 * 80 + 24 * 36 = 24 * (80 + 36) = 24 * 116= 2784 sq. in.To get it in square feet, divide by 144:

2784 / 144 = 19.33 sq. ft.The linear measure of this countertop would be 60 + 80 = 140 inches = 140/12 feet = 11.67 feet

2784 / 144 = 19.33 sq. ft.The linear measure of this countertop would be 60 + 80 = 140 inches = 140/12 feet = 11.67 feet

No need for a claculator to understand these concepts.

A linear function is a function of the form y=ax+b. It contains an independent variable,x, a dependent variable, y, and two constants, a and b,

The value of the constant a is the measure of the rate of change of the function, The value of the constant b is the ordinate (value along the y-axis) where the straight line cuts the y-axis. It is called the y-intercept, or the initial value.

If the value of b=0, the straight line passes through the origin O(0,0). The purists call this type of variation, a direct variation. If b is not equal to 0, it is called a partial variation or some other name.

If you have the graph drawn, b is read off the y-axis: You look at the graph and try to estimate the ordinate of the point where the line cuts (intersects) the y-axis.

To get the rate of change a, you select two points on the line. Let 1st point have coordinates (x1,y1) and the 2nd point have coordinates (x2,y2).

The rate of change is given by the ratio (y2-y1)/(x2-x1). You can also use a= (y1-y2)/(x1-x2). Respect the order in the two expression or you will get the negative value of the rate of change.

Sometimes the voltage will be higher with absolutely NO load. Try a small load and see if it comes down. If not, then need a replacement AVR.

The stopping distance is proportional to square of speed.

that is 90ft proportional to 40^2 mph.

We can write as 90 = X * 40^2. ( X is a constant of proportionality) .

Which implies X = 90 / 1600 = .05625.

Assume S be the distance at which car stops when the speed is 90 mph.

S = X * 90^2. ( since X does not vary as same car is used)

=> S =.05625 * 8100 = 455.625 ft.

Thank you.

http://en.wikipedia.org/wiki/Root_mean_square

In mathematics, the root mean square (abbreviated RMS or rms), also known as the quadratic mean, is a statistical measure of the magnitude of a varying quantity. It is especially useful when variates are positive and negative, e.g., sinusoids.

However, the term "RMS power" is sometimes used in the audio industry as a synonym for "mean power" or "average power". For a discussion of audio power measurements and their shortcomings, see Audio power.
