Line q has a slope of 5/3. Line r is parallel to line q. What is the slope if line r?

seropon [69]

Answer:

The slope remains a constant $m=\frac{5}{3}$ as it is parallel.

Explanation:

1. Line Q is defined as a slope of $\frac{5}{3}$ ; i.e. $y=\frac{5}{3}$

2. Line R is defined to be parallel of Line Q.

3. Line Q is linear and has no domain restrictions.

The definition of being parallel requires the same slope.

Where does the pythagorean identity sin^2 + cos^2=1 come from? How does it relate to right triangles?

Arada [10]

Consider a right triangle with hypotenuse of 1.
sin x means to divide the side in front of the angle by hypotenuse
cos x means to divide the side beside the angle by hypotenuse
we know that a^2+b^2=c^2 now divide two sides by c^2
$\frac{ a^{2} }{ c^{2} }+ \frac{ b^{2} }{ c^{2} }=1$
c is 1 also a/c means sinx and b/c is cos x so
sin^2(x)+cos^2(x)=1

A histogram is an image of data that resembles a bar graph and groups several categories into columns along the horizontal x-axis. The numerical count or percentage of occurrences for each column in the data are shown on the vertical y-axis. To see how data distribution patterns look, utilize columns.

(a) Use classes with a 2 minute width and a 14 minute starting point to create a histogram of the journey times. Thus, the first lesson lasts between 14 and 16 minutes.

Describe the distribution's shape. What is the average journey time interval?

If a histogram has a bell shape, its center and spread can be used to parsimoniously characterize it. The axis of symmetry is located at the middle. The spread is the separation between the center and a particular point of inflection. The inflection points of the bell-shaped histogram are indicated here.
