Agroup of children decide to run a lemonade stand in their neighborhood. they plan
to charge $0.75 for each glass of lemonade, and they spend $6 on supplies.
the function y = 0.75x - 6 models their profits, y, after selling x glasses of lemonade.
what is the zero of that function, or the point at which they will break even?

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..

10 you would take 50/ .2

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
