The required nonreal solution of the given equation 4x⁴ – 8x³ + 4x² – 128x – 960 = 0 is –4i, 4i.
The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.
Here,
The given expression,
4x⁴ – 8x³ + 4x² – 128x – 960 = 0.
Factorization
4.(x + 3).( x - 5).(x² + 16) = 0
Now,
x + 3 = 0 ; x - 5 = 0 ; x² + 16 = 0
x = -3 ; x = 5 ; x = ± 4i
Thus, the required nonreal solution of the given equation is –4i, 4i.

A statistical quality control process for cereal production measures the weight of a cereal box. The population standard deviation is known to be 0.09 ounces. If we wish to estimate the population average cereal box weight to within 0.011 ounces and be 94% confident, how large a sample should be used
Answer:
the sample should be 237
Step-by-step explanation:
The computation of the large the sample be used is shown below:
Given that
Standard deviation = 0.09 ounces
margin of error = 0.011
For 94% confidence interval, the z value be 1.88
As we know that
Margin of error = ((z score × standard deviation) ÷ (Sample size))^2
0.011 = (1.88 × 0.09) ÷ (Sample size))^2
0.011 = 0.1692 ÷ (Sample size))^2
So, the sample size be
= 15.38^2
= 236.60
Hence, the sample should be 237
Margret is inviting 3 friends to a party. If each friend will get 8 cookies and each box has 6 cookies, how many boxes does Margret need to get?
Answer:
Margret need to get 4 boxes of cookies.
Step-by-step explanation:
Total friends = 3
Cookies each friend will get = 8
Each box has cookies = 6 cookies
How many boxes does Margret need to get?
Total cookies will be= Total friends x Cookies each friend will get
Total cookies will be= 3 x 8 = 24
If one box has 6 cookies and we need total 24 cookies so, divide 24 by 6 to get number of boxes
Number of boxes = Total cookies/ number of cookies in one box
Number of boxes = 24/6
Number of boxes = 4
So, Margret need to get 4 boxes of cookies.

What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, The total cost to go horseback riding is a dollar per hour plus a $2 fee for renting a helmet.
Let, The number of hours is represented by 'x'.
Therefore, The cost of riding with a helmet is,
= x + 2.
The cost of riding for 3 hours is 3x + 2 and the cost for 4 people is doing the same is, 4(3x + 2).

select Function 4 and use the Range and Domain sliders to identify the range and domain. Complete parts 1 and 2 below. Use the interactive figure to find your answer. Use the left and right arrow keys to move along a slider as needed. Click here to launch the interactive figure.
Answer:
Domain: (-∞, 2] U (3, 6]
Range: (-∞ , 1] U (-1, 4]
Step-by-step explanation:
This is a piecewise function. It has a discontinuity at x=2 and x = 3
The domain of a piecewise function is the union of the domains of each piece of the function. Similarly the range for a piecewise function is the union of the ranges for each piece of the function
Looking at the graph, we can see two subdomains. When x ≤ 2 , we have one subdomain and when x > 3 there is another subdomain. We state this as
D = - ∞ < x ≤ 2 or 3 < x ≤ 6
In interval notation we represent this as
D = (-∞, 2] U (3, 6]
The nature of the brackets is important a [ or ] bracket means that the value to which it is attached is included whereas an open bracket, ( or ) means that value is not included
For example, (-∞, 2] means that everything below x = 2 to -∞ is part of the domain but it does not include -∞; since at -∞, a function is not defined. However it does include 2 in the domain as can be seen by the closed bracket on the right
The other subdomain is for x > 3 (note: a filled circle means the value is included, an empty circle denotes the value is excluded)
The second subdomain is
3 < x ≤ 6
In interval notation, it is (3, 6]
So the total domain is the union of the two intervals
The range is also discontinuous and there are two distinct ranges. The range is nothing but all the set of values generated by the function. So we look at all possible values for y that the function produces
The Range of this function is -∞ < f(x) ≤ 1 or -1 < f(x) ≤ -4
In interval notation this is
R = (-∞ , 1] U (-1, 4]

This is urgent pls as fast as possible
The base ten numbers to base six for the following is
1. 12 (base 10) =20(base 6)
2.31 (base 10) =51(base 6)
3. 41 (base 10) =105(base 6)
The procedure to find the base ten number to base six
We have to divide the number 12 repeatedly by 6 until the quotient becomes 0.
When 12 is divided by 6 the quotient is 2 and the remainder is 0.
When 2 is divided by 6 the quotient is 0 and the remainder is 2.
Now, Write the remainder from top to bottom.
We get [tex]12_{10} =20_{6}[/tex]
Similarly we do, 31 and 41
When 31 is divided by 6 the quotient is 5 and the remainder is 1.
When 5 is divided by 6 the quotient is 0 and the remainder is 5.
Now, Write the remainder from top to bottom.
We get [tex]31_{10} =51_{6}[/tex]
When 41 is divided by 6 the quotient is 6 and the remainder is 5.
When 6 is divided by 6 the quotient is 1 and the remainder is 0.
When 1 is divided by 6 the quotient is 0 and the remainder is 1.
Now, Write the remainder from top to bottom.
We get [tex]41_{10} =105_{6}[/tex]
Therefore, The base ten numbers to base six for the following is
1. 12 (base 10) =20(base 6)
2.31 (base 10) =51(base 6)
3. 41 (base 10) =105(base 6)

If you see marginal cost increasing in a graph, this implies that
a. marginal product must be increasing, too.
b. the additional cost incurred in producing one more unit of output is decreasing.
c. the company is experiencing some inefficiency in production.
d. the productivity of the company is increasing.
If you see marginal cost increasing in a graph, this implies that; b. the additional cost incurred in producing one more unit of output is decreasing.
What is the interpretation of the marginal cost?
The marginal cost is the change in total production cost that comes from making or producing one additional unit.
When marginal product is rising, the marginal cost of producing another unit of output is declining and when marginal product is falling marginal cost is rising. Thus, Option A and D are not correct.
Option C is wrong because Marginal cost helps to increase efficiency in production.
Thus, option B is the correct answer.
