A hiker climbed up from the bottom of a mountain. His elevation increased at a rate of 40 feet each hour.
Which equation models the change in his elevation at 3 hours?
A. (-3)(-40) = -120
B. 3(-40) = 120
C. 3.40 = 120
D. 3(-40) = -120

Find parametric equations for the line. (enter your answers as a comma-separated list of equations. let x, y, and z be functions of t.) the line in the direction of the vector 5 i + 5 j − 6k and through the point (−4, 4, −2).

That table shows measurements (in invhes$ from cubes with different side lengths. which pairs of variables have a linear relationship? check all that apply

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
