the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.
if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:
Answer from: Quest
3-4
step-by-step explanation:
the answer is 3-4 because both 45 and 60 has a multiple of 15.
45/3=15
60/4=15
therefore the odds against selecting a red is 4-3
Answer from: Quest
whole numbers.
step-by-step explanation:
we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.
as we can see m is taken for the number of months for years 1900-2009.
we know that number of months can't be a negative number or decimal number or a fraction.
so, the number of months could be only positive whole numbers.
therefore, whole numbers is more appropriate for the domain of r.

The graph shows the distance y, in inches, a pendulum moves to the right (positive displacement) and to the left (negative displacement), for a given number of seconds x. how many seconds are required for the pendulum to move from its resting position and return? enter your answer in the box.
Nick has box brads. he uses 4 brads for the first project. nick let’s b represent the original number of brads and finds that for the second project, the number of brads he uses is 8 more than half the difference of b and 4. write an expression to represent the number of brads he uses for the second project.
First work with stencil one. use a combination of reflections, rotations, and translations to see whether stencil one will overlap with the original pattern. list the sequence of rigid transformations you used in your attempt, noting the type of transformation, the direction, the coordinates, and the displacement
