Item 14 you develop an app to students complete their homework. to earn money, you sell advertising space on the app’s main screen. an advertiser pays you $20 per month and an additional $0.005 each time the app is opened. graph the linear equation that represents your monthly income y (in dollars) when the app is opened x times.

See attached diagram

Step-by-step explanation:

Let x be the number of times the app is opened and y be your monthly income (in dollars).

If an advertiser pays you  $0.005 each time the app is opened, then he pays you $0.005x for all times the app is opened. Since an advertiser pays you $20 per month, then the total income is

y=20+0.005x.

Plot this line on the coordinate plane (see attached diagram).

he spend 5.1 minutes chatting with his friends

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5 1/10

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
