Question 1195104: Can I please have help with this, thank you! A football is kicked straight up into the air. Its height above the ground is approximated by the relation y=25x-5x^2, where y is the height of the ball in meters and x is the time in seconds. There are two times when the football is 27.5m in the air, on the way up and on the way down. Joe realizes that using the equation y=27.5, he can determine the two times the ball is 27.5 meters in the air. Algebraically or graphically determine these two times?

Question 1195830: Median weekly earnings for women with some college for an associate degree.
1980.......$231
2013.............$657
Using today's dollars, the data in the bar graph can be described by the mathematical model
W = 13n + 231,
Where W represents median weekly earnings n years after 1980.
Does the formula underestimate or overestimate the median weekly earnings in 2013? By how much?

Question 1195891: 32 Portfolio Management A portfolio manager is concerned that two stocks generate an annual income of $15,000 for a client. The two stocks earn annual dividends of $2.40 and $3.50 per share, respectively. If x equals the number of shares of stock 1 and y equals the number of shares of stock 2, the equation
2.4x+3.5 15,000
states that total annual dividend income from the two stocks should total $15.000 Rewrite the equation in slope-intercept form and interpret the meaning of the slope and y intercept in this application. Solve for the x intercept and interpret its meaning.
