Write and simplify the integral that gives the arc length of the following curve on the given interval b.

if necessary, use technology to evaluate or approximate the integral.

y: 31n x, for 2sxs5

a. the integral that gives the arc length of the curve is l dx

b. the arc length of the curve is approximately (round to three decimal places as needed.)

Which of the following could be the graph of the equation y = -2x + 5

What will the graph look like for a system of equations that has no solution? a. the lines will be perpendicular. b. the lines will cross at one point. c. both equations will form the same line. d. the lines will be parallel.

Lin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. she knows that the total cost to download 3 videos was $12. her work to find the equation is shown below. joylin’s work step 1 k= 3/12= 0.25 step 2 y= 0.25x where did joylin make her first error?
