Solve the equation. (Find only the real solutions. Enter your answers as a comma-separated list.) x4 − 8x2 + 7 = 0
ryzh [129]

Answer: x=0 or x= plus or minus 2

Step-by-step explanation:

g(x)=x^4-8x^2+7

Critical numbers are the numbers where the first derivative is zero

g'(x)=4x^3-16x+0

=4x^3-16x

g'(x)=0

Implies

4x^3-16x=0

4x(x^2-4)=0

4x=0 OR x^2-4=0

x=0 or x^2=4

x=0 or x= plus or minus 2

What is the sum of the arithmetic series below? Use the formula for the sum of an arithmetic series.
Papessa [141]
To determine the sum of the arithmetic series, simply remember that i is the pattern that you are going by which is 1,2,3.

The top value on the sigma sign tells you the final value that you must go to.

So use the equation to go from 1 to 18. So it would be 2(1) + 9 + 2(2) + 9 etc.

Mark traveled 455 miles in 5 hours. At this rate how far could he travel in 7 1/2 hours
marshall27 [118]
Mark could travel 682.5 miles in 7.5 hours.

To solve this you have to find how fast he travels per hour.
455 miles/5 hours=91 mph
91 mph multiplied by 7.5 hours(91 x 7.5)= 682.5
682.5 Miles in 7.5 hours

Hope this helped you! :D
