A third-order polynomial of the form y = Ax³ + Bx² + Cx + D is to be fitted to four time-velocity data points. At time x = 0, 1,

2, and 3 s, the velocity is measured as 7, 14, 29, and 58 m/s.
Using Gauss-Jordan elimination, find the curve that passes through these points. Also, solve the problem by employing the backslash operator in MATLAB and compare the results with those obtained earlier.

What is the formula for finding slope?
ozzi

Answer:

To find the slope of two given points, you can use the point-slope formula of (y2 - y1) / (x2 - x1). With the points plugged in, the formula looks like (3 - 2) / (4 - 1). Simplify the formula to get a slope of ⅓.

The slope is the amount it will cost you per mile, in addition to the flat fee represented by the y-intercept.  (The cost before driving any miles.)

So b. is the  correct answer as;

$25 is the cost per day to rent the car and $0.15 is the cost per mile.

If the diameter of a youth baseball is 2. 8 inches and the diameter of an adult softball is 3. 8 inches, what is the approximate
Molodets [167]

The approximate difference in their volumes is 17.2 cubic inches

<h3>How to determine the difference in the volume?</h3>

The given parameters are:

Diameter, d = 2.8

Diameter, D = 3.8

The radii are the half of the diameter.

So, we have:

r = 1.4

R = 1.9

The volume of the balls is then calculated using:

V = \frac{4}{3}\pi r^3

The difference is then represented as:

D = \frac{4}{3}\pi (R^3 - r^3)

Substitute known values

D = \frac{4}{3}* 3.14* (1.9^3 - 1.4^3)

Evaluate

D = 17.2

Hence, the approximate difference in their volumes is 17.2 cubic inches
