Thanks, guys!! I know the answers, but I need to know how to get the answers...
1. A rectangular city park has a jogging loop that goes along a length, width, and diagonal of the park. To the nearest yard, find the length of the jogging loop, if the length of the park is 125 yards and its width is 75 yards...
Answer: 346 yards
2. An investment is worth $3070 in 1995. By 2000 it has grown to $5440. Let y be the value of the investment in the year x, where x=0 represents 1995. Write the linear equation that relates of the investment, y to the year x.
Answer: y=474x+3070
3. Find the general form of the equation for the line with the given properties. Slope= 2/3, containing (0,5)
Answer: -2x+3y=15
4. Each month a gas station sells x gallons of gas at $1.92. The cost to the owner of the gas station for each gallon is $1.32. The monthly fixed costs for running the gas station is $37,000. Write an equation that relates the monthly profit in dollars, to the number of gallons of gasoline sold. Then use the equation to find the monthly profit when $75,000 gallons of gas are sold in a month.
Answer: P=0.60x-37,000
$8,000
5. Find and simplify the difference quotient f(x+h)-f(x)/h, h cannot equal 0 for the given function.
f(x)=x^2+6x+7
Answer: 2x+h+6
