Acomputer manufacturer built a new facility for assembling computers. there were construction and new equipment costs. the company paid for these costs and made combined profits of $40 million after 4 years while profits increased $30 million per year. select the correct graph of this function.

The second graph is correct for this function.

Step-by-step explanation:

The company made combined profits of $40 million after 4 years. The profits increased $30 million per year.

Therefore the rate of change of profit function is 30 and the graph of profit function passing through the point (4,40).

Point slope of a linear function is

Add 40 both sides.

Therefore the profit function is defined as

Put x=0

Therefore y-intercept of function is -80. So, second graph is correct for this function.

Y-intercept of first graph is positive and y-intercept of third and fourth graph  are more that -50, therefore option 1, 3 and 4 are incorrect.

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.
