the function f(x) = 2x^2 + 3 represents the rate of a boat traveling with the current in miles per hour. the function g(x) = x + 2 represents the time the boat traveled in hours. solve (f • g)(2), and interpret the answer.
(f • g)(2) = 15, the distance in miles the boat traveled
(f • g)(2) = 15, the number of boats
(f • g)(2) = 44, the distance in miles the boat traveled
(f • g)(2) = 44, the number of boats

What is the equation in point slope form of the line that passes through the point (-1, -3) and has a slope of 4? y-1=4(x-3) or y+3=4(x+1)

What is the equation of a vertical line passing through the point (−5, −1)? y = −5 y = −1 x = −5 x = −1

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
