"a man drove 10 mi directly east from his home, made a left turn at an intersection, and then traveled 5 mi north to his place o

Mariulka [41]

Answer:

11.2 miles

Step-by-step explanation:

We can create a triangle from the information given.

We can call the starting point (0,0) in the coordinate system.

10 mi east - 10 miles to the right. then,
5 mi north - 5 miles above

See the attached picture. The direct distance is labeled as x.

Now we need to find x using pythagorean theorem.

Pythagorean Theorem = leg²+leg²=hypotenuse²

Solving for x:

$10^2+5^2=x^2\\100+25=x^2\\125=x^2\\x=\sqrt{125}\\x=11.18$

Rounding to nearest tenth, we have 11.2 miles

What are the real or imaginary solutions of the polynomial equation x*4-25=0

Paul [167]

Hello from MrBillDoesMath!

Answer:

Solutions: x = +\- 5i or x = +\- sqrt(5)

Discussion:

Factor x^4 - 25:

x^4 - 25 = (x^2+5) (x^2-5) => factor x^2 - 5

x^4 - 25 = (x^2+5)(x + sqrt(5)) (x - sqrt(5)) => factor x^2 + 5

x^4 = 25 = (x +5i)(x-5i) (x + sqrt(5)) (x - sqrt(5))

Hence the solutions are

x = +\- 5i and x = +\- sqrt(5)

Thank you,

MrB
