Estimate the minimum number of subintervals to approximate the value of integral from negative 5 to 5 left parenthesis 2 x squared plus 4 right parenthesis dx with an error of magnitude less than 5 times 10 superscript negative 4 using a. the error estimate formula for the trapezoidal rule. b. the error estimate formula for simpson's rule.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

part a: 1.08
