X=rcos∅=r cos (-210)=r cos 210=rcos (180+30)=-r cos 30
x=-r* \frac{sqrt 3}{2} = \frac{- sqrt 3r}{2} ,
y=r sin (-210)=-rsin 210=-rsin (180+30)=-r(-sin 30)
1or y=r sin 30=r* \frac{ 1}{2} = \frac{r}{2}

Classify each of the following random variables as either discrete or continuous: a. The fuel efficiency (mpg) of an automobile
MrRissso [65]

Answer:

a. The fuel efficiency (mpg) of an automobile is a continuous variable

b. The amount of rainfall at a particular location during the next year is a continuous variable

c. The distance that a person throws a baseball is a continuous variable

d. The number of questions asked during a 1-hr lecture is a discrete variable

e. The tension (in pounds per square inch) at which a tennis racket is strung is a continuous variable

f. The amount of water used by a household during a given month is a continuous variable

g. The number of traffic citations issued by the high- way patrol in a particular county on a given day is a discrete variable

Step-by-step explanation:

<em>Continuous </em>variables assign values in a range of infinitely many values, while <em>discrete</em> variables are countable.

<em>Continuous variables</em> in the above can assume real numbers and there are infinitely many real numbers between any two real numbers.

<em>Discrete variables </em>above can be counted in the given time interval.

Integrate (x^3)/(a^2)-(x^2) ?
notka56 [123]

Hi!

\frac{x^3}{(a^2)-(x^2)}

<em>First remove parenthesis.</em>

\frac{x^3}{a^2-x^2}

<em>Factor a^2-x^2 or (x+a)(a-x)</em>

=\frac{x^3}{(a+x)(a-x)}

Hope this helps! Thank you for posting your question at here on Brainly. Have a great day.

Audrey has $120 to spend on a tennis racket and lessons. The racket costs $45 and the lessons cost $15 per hour. Define a variab
vodka [1.7K]
I would do 120 - 45. Now that she has 75 left I would do 75 - 15 * 3 Since 45 Is all that she has left.

If I were you choose a variable I would say h for hours. And h is equal to 3.

In result the whole equation would be 120 - 45 - 15 * h but since h is equal to 3 , We can write it as 120 - 45 - 15 * 3. Leaving Audrey with $30 left.

Correct me if I am wrong :)
