Joseph tweets 13 times a day. define each variable and write an algebraic expression to describe the number of posts after any given number of day.

It is given that:

Joseph tweets 13 times a day.

Let x represents the number of days since he starts to tweet.

and y represents the number of tweets.

Hence, we know that y is the dependent variable i.e. the output variable since it's value is obtained corresponding to the variable x.

and x is the independent variable or the input variable since it is assigned to the equation.

Hence, the algebraic equation which describes the number of posts after any given number of day is given by:

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
