The degree of a polynomial is the highest power of the variable in a polynomial expression.
From the given information:
with real coefficients having zeros 2 and 4 i and a lead coefficient of 1.
Then
We know that the complex zeros always occur in pairs.
zeros are 2,4i,-4i
f(x)=(x-2)(x-4i)(x+4i)
f(x)=(x-2)((x)^2-(4i)^2)
f(x)=(x-2)(x^2-16i^2)
f(x)=(x-2)(x^2+16)

The profit, in dollars, a company makes selling a new line of iPhones is given by the
equation P(x) = −0.03x^2 + 225x − 24000, where x is the number of iPhones sold.
a) Find the instantaneous rate of change of the profit at x = 1000 iPhones sold.
b) Interpret your result.
Answers
The instantaneous rate of change is the change in the concentration of rate that occurs at a particular point of time. The variation in the derivative values at a particular point denotes the instantaneous rate of change. The instantaneous rate of change at a point is the value of derivative function evaluated at that point.
P(x) = −0.03x^2 + 225x − 24000
To find the instantaneous rate of change we need to differentiate the equation with respect to x
P'(x) = -0.06x +225
at x =0
P'(0)= 225
now put x = 1000 because we need to know instantaneous rate of change of the profit at x = 1000 iPhones sold
P'(1000) = -0.06(1000) + 225
= -60 + 225
= 165
Hence, the instantaneous rate of change of the profit at x = 1000 iPhones sold is 165
This means that the increase in sales also increase the profit but at a decreasing rate or the marginal profit of iPhones increases with decreasing rates

How wide and how long does Delilah need to make her garden to achieve the desired speciation?
Width =
Answers
The equation is 50 = (5 + w)w and the width is 5 and the length is 10
Write the equation that Delilah should use to determine the width of a garden that has an area of 50 square feet.The given parameters are
Area = 50
Length = 5 + Width
This means that
l = 5 + w
The area is calculated as
A = lw
Substitute l = 5 + w in A = lw
A = (5 + w)w
Substitute A = 50 in A = (5 + w)w
50 = (5 + w)w
Hence, the equation is 50 = (5 + w)w
How wide and how long does Delilah need to make her garden to achieve the desired speciation?We have
50 = (5 + w)w
Express 50 as 10 * 5
So, we have
10 * 5 = (5 + w)w
This means that
5 + w = 10
w = 5
Solve 5 + w = 10
w = 5
Substitute w = 5 in l = 5 + w
l = 5 + 5
l = 10
Hence, the width is 5 and the length is 10

The midpoint of AB is M(0, -3)M(0,−3). If the coordinates of AA are (6, -5)(6,−5), what are the coordinates of BB?
Answers
Step-by-step explanation:
Mid point of AB is (0, -3)
Coordinate of A is (6, -5)
By using mid point formula, if P(x, y) and Q (x′, y′), then mid point of P= (x + x′)/2 , (y + y′)/2
So, ( 0, -3)= 6+x/2, -5+y/2
0=6+x/2
0=6+x, x = -6
and, -3= -5+y/2, -6= -5+y....
y = -1
so the coordinate is (-6, -1)
To find the midpoint of two points, we can use the following formula:
[tex]midpoint=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
[tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two endpointsSolving the QuestionWe're given:
AA = (6, -5)AB = (0, -3)BB = [tex](x_2,y_2)[/tex]Plug the information into the formula:
[tex]midpoint=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})\\\\(0,-3)=(\dfrac{6+x_2}{2},\dfrac{-5+y_2}{2})[/tex]
If [tex]\dfrac{6+x_2}{2}[/tex] must equal 0, then [tex]x_2[/tex] must be -6.
If [tex]\dfrac{-5+y_2}{2}[/tex] must equal -3, then [tex]-5+y_2[/tex] must equal -6, making [tex]y_2[/tex] equal to -1.
Therefore, BB is (-6,-1).

A.Hint: Find the common denominator and then add.
Answers
The simplification of the given equation is (x² + 8x - 16)/(x-4)(x+4) by the method of LCM.
What is defined as the LCM?LCM is an abbreviation for least common multiple. The smallest number which is a multiple of both numbers is the least common multiple of them.For, the given equation;
4/(x+4) + (x/x-4)
To find the common denominator, use LCM; multiply a first term by (x-4)/(x-4) and the 2nd term by (x+4)/(x+4):
= (x-4)×4/(x-4)(x+4) + x×(x+4)/(x-4)(x+4)
The following step is to disperse the 4 (x-4) and x (x+4);
So you now have;
= (4x-16 + x² + 4x)/(x-4)(x+4)
Further simplify.
= (x² + 8x - 16)/(x-4)(x+4)
As, (x² + 8x - 16) is further not factor-able. So, the simplified form of the given equation is; (x² + 8x - 16)/(x-4)(x+4).

How to find the residual of a scatter plot?A residual plot is a type of scatter plot where the horizontal axis represents the independent variable, or input variable of the data, and the vertical axis represents the residual values.
Now, looking at the given residual plot and using a calculator online, we can say that the equation of the least squares regression line is;

Answer:
The function's minimum value is -12.
Step-by-step explanation:
Integers x are used to define the function g(x), and it is defined so that if x is even, g(x) = x/2 and if x is odd, g(x) = x + 5.
Considering, g(x)=x2 - 6x - 12
requested to determine the minimal value
Put x=0 to obtain the minimal value of g(x).
When x=0 is entered, the value of x2 is changed to 0.
6x's value is also reduced to 0.
so the equation g(0) becomes 0-0-12
g(0)= -12
on putting x=0 we get g(0) as -12 which is its minimum value
we get minimum value for g(x) when x=0
