For the vectors Bold uequalsleft angle negative 8 comma 0 comma 1 right angleand Bold vequalsleft angle 1 comma 3 comma negative
trapecia [35]

Answer:

Step-by-step explanation:

Given that there are two vectors U = (-8,0,1)

V = (1,3,-3)

To find projection of u on V and also projection of V on U

First let us find the dot product U and V

U.V = -8(1)+0(3)+1(-3)\\= -11

Projection of U on V =\frac{U.V}{|V|} \\=\frac{-11}{\sqrt{1+9+9} } \\=\frac{-11}{\sqrt{19} }

Similarly projection of V on U

=\frac{U.V}{|U|} \\=\frac{-11}{\sqrt{64+0+1} } \\=\frac{-11}{\sqrt{65} }

The points (0, 1) and (-9, -9) fall on a particular line. What is its equation in slope-intercept form?
prohojiy [21]

The slope-intercept form:

y=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

m - slope

b - y-intercept → (0, b)

We have the points (-9, -9) and (0, 1) - y-intercept → b = 1.

Calculate the slope:

m=\dfrac{1-(-9)}{0-(-9)}=\dfrac{10}{9}

Answer: y=\dfrac{10}{9}x+1

decide whether the random variable x is discrete or continuous. x represents the length of time it takes to get to work
FromTheMoon [43]

The given variable is a continuous variable.

<h3>What is continuous variable?</h3>

A quantitative variable can be either continuous or discrete depending on whether it is normally obtained through measurement or counting. A variable is continuous over a range of real values if it can take on any two specific real values and all other real values in between.

<h3>What is mercury thermometer?</h3>

In Amsterdam, physicist Daniel Gabriel Fahrenheit created the mercury thermometer, also known as a mercury-in-glass thermometer. It consists of a glass tube with a small diameter and a mercury bulb attached to it; the bulb contains far more mercury than the tube does.

<h3>According to the information:</h3>

A mercury thermometer was used to take the subject's temperature.

Because of the temperature:

  • Not counting but measuring it.
  • You can use a decimal number to represent its value.
  • As a result, it is open to any value inside an interval.
  • Temperature is therefore a continuous variable.
  • The only format in which discrete values can be stated is as whole numbers.

so

Temperature is a continuous variable,
