Gregor threw a softball ☺

of the length of the yard in

front of his house. Find as

many fractions as you can

that name the same part of

the length that Gregor

threw the ball. Solve this

problem any way you

choose. Explain how you

decided

Suppose that x and y are both differentiable functions of t and are related by the given equation. use implicit differentiation with respect to t to determine startfraction dy over dt endfraction in terms of x, y, and startfraction dx over dt endfraction .

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

Negative 5 1/12 + negative 4 1/4 + 6 3/4
