Find the length of the stock needed to create the shape as shown the right. A stock with a thickness of 4 centimeters can be divided into three parts from left to right: a vertical part of length 20 centimeters; a curved surface extending outwards that is one-quarter of a full circle of radius 8 centimeters; horizontal part of length 25 centimeters. The length of the stock needed to create the shape is approximately nothing ▼ cm squared . cm. (Simplify your answer. Round to the nearest tenth as needed.)

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

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.
