Jill’s coach used a computer program to help her improve the distance she can throw a softball. The computer gave a readout of the path of her best throw. The path of this throw was represented by the quadratic equation
y = –0.15x2 + 1.3x + 4, where x represents the number of feet the ball traveled and y represents the height of the ball in feet. Use the graphing calculator to graph the equation. At what distance did the ball hit the ground? Round your answer to the nearest hundredth.

Factor -8x3-2x2-12x-3 by grouping what is the resulting expression?

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?

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
