Jordan recorded the number of sit-ups he completed during the first 4 track practices. Which of Jordan's friends completed double the amount of sit-ups that Jordan

completed during each practice?

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

8 2/3 is the answer

step-by-step explanation: just use a calculator

unless if u could do my questions, if not i wouldn't want to

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.
