Timothy has 15 letters and 32 memos to type for his manager. He estimates that
each letter will take 40 minutes to type
and each memo will take 15 minutes to
type. He gets paid $5 a letter and $2 a
memo. If he works for a maximum of 5
hours (300 minutes), how many letters
and memos should Timothy type in
order to maximize his wages?

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
