what are the solutions of the equation x4 95x2 – 500 = 0? use factoring to solve. and x = ±10 and x = ±10i and x = ±10i and x =
Andreas93 [3]

Doing factorization, we know that the factors of the given equation are ±√5 and ±10i.

<h3>What is Factorization?</h3>

In mathematics, factorization or factoring consists of writing a number or any mathematical item as a product of several factors, typically small or easier objects of the same.

For example, 3 × 5 is a factorization of an integer 15 and is a factorization of an equation x² – 4.

So, we have the equation:

x⁴ + 95x² – 500 = 0

Factorizing the above equation:

x⁴ + 100x² - 5x² - 500 = 0

x²(x² + 100) - 5(x² + 100) = 0

(x² - 5)(x² + 100) = 0

Solving further:

x² = 5

x² = -100

x = ±√5

x = √-100

Factors: ±√5 and ±10i

Therefore, doing factorization, we know that the factors of the given equation are ±√5 and ±10i.

The data in the table represent the height of an object over
Arada [10]

<u>Answer:</u>

The correct answer option is quadratic, because the height increases and then decreases.

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

We are given the following data in the table which represents the height of an object over  time:

Time (s)          Height (ft)

     0                      5

      1                     50

     2                     70

     3                     48

We know that in situation where the values increase and then decreases, a quadratic model is used.

From the values given in the table, we can see that the values of height first increased and then decreased with the increase in time.

Therefore, the model used is quadratic, because the height increases and then decreases.

Ms. Robinson gave her class 12 minutes to read. Carrie read 5 1/2 pages in that time. At what rate, in pages per hour, did Carri
cricket20 [7]
The answer is:  " 27.5 pages " ; or, write as:  " 27 \frac{1}{2} pages " .
____________________________________________________________

5.5 pages / 12 minute = ? pages / 60 minutes; 


12 * 5 = 60 ;

5.5 * 5 = ? 


5.5 * 5 =   27.5
____________________________________________________________
The answer is:  " 27.5 pages " ; or, write as:  " 27 \frac{1}{2} pages " .

Rewrite the expression in z to the n power. The expression I was given is: 1 over z to the negative 1 half power.
12345 [234]

Answer:

The equivalent expression is;

\frac{1}{z^{-\frac{1}{2}}}=z^{\frac{1}{2}}

Step-by-step explanation:

The given expression is:


\frac{1}{z^{-\frac{1}{2} }}

Recall that:

\frac{1}{a^{-m}}=a^m


In our case, a=z and  m=\frac{1}{2}.


We use this property of exponent to obtain;

\frac{1}{z^{-\frac{1}{2}}}=z^{\frac{1}{2}}
