The company estimated that they would sell 500 caps during the football season. They actually sold 575. Find the percent error.
Paraphin [41]

Answer:  

13.1%

Step-by-step explanation:  

The company estimated that there would be 500 a ps during the football season

The actually sold 575

Therefore the percent error can be calculated as follows

= 575-500/575 × 100

= 75/575 × 100

= 0.1304×100

= 13.1%

Hence the percent error is 13.1%

What are all of the real roots of the following polynomial? f(x) = x^4 -24x^2 - 25 A. -1 or 1 B. -5 or 5 C. -5, -1, 1, or 5 D. -
professor190 [17]

For this case we have the following function:

f (x) = x ^ 4-24x ^ 2-25

We make a change of variable:

u = x ^ 2

So, we have:

u ^ 2-24u-25

We apply the resolver:

a = 1\\b = -24\\c = -25\\

u = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}\\u = \frac {- (- 24) \pm \sqrt {(- 24) ^ 2-4 (1) (- 25)}} {2 (1)}\\u = \frac {24 \pm \sqrt {576 + 100}} {2}\\u = \frac {24 \pm \sqrt {676}} {2}\\u = \frac {24\pm26} {2}

We have two roots:

u_ {1} = \frac {24 + 26} {2} = 25\\u_ {2} = \frac {24-26} {2} = - 1

Returning the change:

x ^ 2 = 25\\x = \pm \sqrt {25} = \pm5

x ^ 2 = -1 Give the imaginary roots.

Answer:

Real roots \pm5
