Roger is paid $50 to sell videos of a play to an audience after the play is
performed.
he also receives $2 for each video he sells. the function e(v)=50+2v
models the amount of money roger earns by selling v videos. the play's audience
consists of 230 people and each audience member buys no more than 1 video.
what is the practical domain of the function? show how you
determined/defined the practical domain. what is the most that roger
can earn?

0 ≤ v ≤ 230

Step-by-step explanation:

The function E(v)=50+2v models the amount of money Roger earns by selling v videos.

Roger is paid $50 to sell videos of a play to an audience after the play is performed. He also receives $2 for each video he sells.

Now, it is given that the play's audience consist of 230 people and each audience member buys no more than 1 video.

Therefore, the domain of the function will be given by  

0 ≤ v ≤ 230

here v = 0 when each audience buys zero video and v = 230 when each audience buys 1 video. (Answer)

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

25.2

step-by-step explanation:

2+4x6-8/10= 25.2
