Unit 1: module 1: place value and decimal fractions, unit 2: module 2: multi-digit whole number and decimal fraction operations, unit 3: module 3: addition and subtractions of fractions, unit 4: module 4: multiplication and division of fractions and decimal fractions, unit 5: module 5: addition and multiplication with volume and area, unit 6: module 6: problem solving with the coordinate plane.
Applying the Quadratic Formula (Part 1)
Select all the equations that have 2 solutions.
\((x + 3)^2 = 9\)
\((x - 5)^2 = \text- 5\)
\((x + 2)^2-6 = 0\)
\((x - 9)^2+25 = 0\)
\((x + 10)^2 = 1\)
\((x - 8)^2 = 0\)
\(5=(x+1)(x+1)\)

A frog jumps in the air. The height, in inches, of the frog is modeled by the function \(h(t) = 60t-75t^2\) , where \(t\) is the time after it jumped, measured in seconds.
Solve \(60t - 75t^2 = 0\) . What do the solutions tell us about the jumping frog?
A tennis ball is hit straight up in the air, and its height, in feet above the ground, is modeled by the equation \(f(t) = 4 + 12t - 16t^2\) , where \(t\) is measured in seconds since the ball was thrown.
- Find the solutions to the equation \(0 = 4 + 12t - 16t^2\) .
- What do the solutions tell us about the tennis ball?
Rewrite each quadratic expression in standard form.
- \((x+1)(7x+2)\)
- \((8x+1)(x-5)\)
- \((2x+1)(2x-1)\)
- \((4+x)(3x-2)\)
Find the missing expression in parentheses so that each pair of quadratic expressions is equivalent. Show that your expression meets this requirement.
- \((4x-1)(\underline{\hspace{1in}})\) and \(16x^2 -8x +1\)
- \((9x + 2)(\underline{\hspace{1in}})\) and \(9x^2 -16x -4\)
- \((\underline{\hspace{1in}})(\text-x + 5)\) and \(\text-7x^2 +36x-5\)
The number of downloads of a song during a week is a function, \(f\) , of the number of weeks, \(w\) , since the song was released. The equation \(f(w) = 100,\!000 \boldcdot \left(\frac{9}{10}\right)^w\) defines this function.
- What does the number 100,000 tell you about the downloads? What about the \(\frac{9}{10}\) ?
- Is \(f(\text-1)\) meaningful in this situation? Explain your reasoning.
Consider the equation \(4x^2 - 4x -15 = 0\) .
- Identify the values of \(a\) , \(b\) , and \(c\) that you would substitute into the quadratic formula to solve the equation.
Evaluate each expression using the values of \(a\) , \(b\) , and \(c\) .
\(\text- b\)
\(b^2 - 4ac\)
\(\sqrt{b^2 - 4ac}\)
\(\text- b \pm \sqrt{b^2 - 4ac}\)
\(\dfrac{\text- b \pm \sqrt{b^2 - 4ac}}{2a}\)
- The solutions to the equation are \(x=\text-\frac 32\) and \(x=\frac52\) . Do these match the values of the last expression you evaluated in the previous question?
- Describe the graph of \(y=\text-x^2\) . (Does it open upward or downward? Where is its \(y\) -intercept? What about its \(x\) -intercepts?)
Without graphing, describe how adding \(16x\) to \(\text-x^2\) would change each feature of the graph of \(y = \text-x^2\) . (If you get stuck, consider writing the expression in factored form.)
- the \(x\) -intercepts
- the \(y\) -intercept
- the direction of opening of the U-shape graph
