  • Radicals Help!?

    The time in years, T, for one complete orbit of a planet around a star can be calculated from the equation:

    T=√ Kr3

    The average radius, in kilometres, of the planet’s orbit is r, and K is a constant that changes depending on the mass of the star.

    (1) Rearrange the equation to isolate K.

    Then calculate for K for Earth’s solar system knowing that Earth takes one year to go around the sun and that the radius of Earth’s orbit is 1.49 x 10^8 km from the sun

    (2) Calculate how many Earth years it takes Neptune to complete an orbit. Neptune’s average orbital radius is 4.5 x 10^9 km.

  • Solving Quadratic Inequalities in One Variable?

    800 people will attend a concert if tickets cost $20 each. Attendance will decrease by 30 people for each $1 increase in the price. The concert promoters need to make a minimum of $12 800.

    What quadratic inequality represents this situation?

    What is the range of ticket prices the concert promoters can charge and still make at least the minimum amount of money desired?

    Solving Systems of Equations Algebraically?

    A canopy tour company designs zip line rides through forest and jungle environments. One particular zip line takes the passenger through a waterfall, the maximum height of which is 167 ft. The dimensions of both the zip line and the waterfall are shown in the image below. 

    Model this scenario with a system of equations.

    Hint, use:

    y = mx + b

    and

    y = a(x -p)2 + q

  • Solving Quadratic Systems Graphically?

    Solve the following systems by graphing on your calculator or a website and give the solution

    Then show how the solutions would be verified, by using the LEFT SIDE = RIGHT SIDE method

    y=2x^2 + 7x − 5

    y=−1/3^2 − 2x + 9
