To determine To calculate: The velocity and acceleration function of the given position function s ( t ) = 7 t 2 + 2 t + 10 . Explanation Given: The position function is s ( t ) = 7 t 2 + 2 t + 10 . Formula used: The velocity of an object: v = d s ( t ) d t = s ′ ( t ) Here, v is the velocity of the object and s is the position of the object. and a = d 2 s ( t ) d t 2 = s ″ ( t ) Here, a is the acceleration of the object and s is the position of the object. Calculation: The function is given as s ( t ) = 7 t 2 + 2 t + 10 . The first derivative of the position function with respect to time gives the velocity function.. d d t ( s ( t ) ) = d d t ( 7 t 2 + 2 t + 10 ) v ( t ) = d d t ( 7 t 2 ) + d d t ( 2 t ) + d d t ( 10 ) = 7 ( 2 t ) + 2 ( 1 ) + 0 Further solve, v ( t ) = 14 t + 2 …... (1) Thus, the velocity function is v ( t ) = 14 t + 2

Family of Curves

A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These…

XZ Plane

In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are…

Euclidean Geometry

Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) ge…

Lines and Angles

In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.

Name: Lab Time: Quiz 7 & 8 (Take Home) - due Wednesday, Feb. 26 Contingency Analysis (Ch. 9) In lab 5, part 3, you will create a mosaic plot and conducted a chi-square contingency test to evaluate whether elderly patients who did not stop walking to talk (vs. those who did stop) were more likely to suffer a fall in the next six months. I have tabulated the data below. Answer the questions below. Please show your calculations on this or a separate sheet. Did not stop walking to talk Stopped walking to talk Totals Suffered a fall Did not suffer a fall Totals 12 11 23 2 35 37 14 14 46 60 Quiz 7: 1. (2 pts) Compute the odds of falling for each group. Compute the odds ratio for those who did not stop walking vs. those who did stop walking. Interpret your result verbally.

Solve please and thank you!
