A = s^2
A' = 2s*s'

When the area is 36 cm^2, the side (s) is 6 cm. The area is increasing at the rate
A' = 2(6 cm)*(6 cm/s) = 72 cm^2/s

What are all of the real roots of the following polynomial? f(x) x^4-24x^2-25

Greeley [361]

<u>Answer:</u>

x = ±5

<u>Step-by-step explanation:</u>

We are given the following polynomial function and we are to find all of its real roots:

$x^4-24x^2-25$

Let $y=x^2$ so we can now write it as:

$y^2-24y-25$

Factorizing it to get:

$(y^2+y)+(-25y-25)$

$y\left(y+1\right)-25\left(y+1\right)$

$\left ( y + 1 \right ) \left ( y - 2 5 \right)$

Substitute back $y=x^2$ to get:

$\left ( x^2 + 1 \right ) \left ( x^2 - 25 \right )$

$\left ( x^2 + 1 \right ) \left ( x + 5 \right ) \left ( x - 5 \right )$

The quadratic factor has only complex roots. Therefore, the real roots are x = ±5.

The total amount of deductions from an employee’s gross pay is $83.20. If the gross pay is $378.18, what percent of their gross

Masja [62]

Answer:

22%

Step-by-step explanation:

A percent of something can be thought of as part of that thing divided by the total amount of the same thing and multiplied by 100%.

In this case, the part of the thing is part of a paycheck. The total thing is the total paycheck.

$Percent=\frac{Part}{Total} *100%$ %

$Percent=\frac{83.20}{378.18} *100=0.2200*100=22.000$ %
