What are the possible numbers of positive, negative, and complex zeros of f(x)=-3x^4+5x^3-x^2+8x+4

Mathematics
1 answer:
Andru [333]2 years ago
7 0

Answer:

There could be 0, 2, or 4 complex solutions

Step-by-step explanation:

The Fundamental Theorem of Algebra states that any polynomial with n degree will have n solutions So since the degree of the polynomial you provided has a degree of 4, that means there are 4 possible solutions. This question specifically asks for complex zeroes. Complex zeroes come in conjugate pairs, so that means if you have one complex zero, there is another complex zero which is it's conjugate. For this reason, there can only be an even number of complex zeroes. And since there's 4 possible solutions, There could be 0, 2, or 4 complex solutions

What is the domain of the function y=-720t + 3600 ?
Colt1911 [192]

Answer:

We conclude that:

\mathrm{Domain\:of\:}\:-720t+3600\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:

Please also check the attached graph.

Step-by-step explanation:

Given

Given the function

y=-720t\:+\:3600

To determine

What is the domain of the function y=-720t + 3600

We know that the domain of the function is the set of input argument values for which the function is real and defined.

Given the function

y=-720t\:+\:3600

From the given function, it is clear that the function has no undefined points nor domain constraints.

Therefore, the domain of the function is

-\infty \:

Thus, we conclude that:

\mathrm{Domain\:of\:}\:-720t+3600\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:

. The volume of a cube is 1728 . Find its edge and total surface area
emmasim [6.3K]

Answer:

Edge = 12

Total Surface Area = 72

Step-by-step explanation:

Volume of the cube = 1728

Length of the edge = \sqrt[3]{1728}  = 12

We know that

TSA (Total Surface Area) = 6 {a}^{2}

where a = length of edge of cube

So,

TSA of cube = 6 \times 12 = 72

Which of the following transformations will result in an image that maps onto itself
Anestetic [448]

The transformations that maps image onto itself are D) reflect over the y axis and then reflect again over the y axis.

Complete question

Which sequence of a transformation will result in an image that maps onto itself? A) rotate 180 degrees counterclockwise and then reflect across the x axis b) reflect over the y axis and then reflect over the x axis c) rotate 180 degrees counterclockwise and then reflect across the y axis d) reflect over the y axis and then reflect again over the y axis

Step-by-step explanation:

Reflecting a figure across the y axis then repeating the same procedure will take you to the original position. This means mapping the figure onto itself.When coordinates(x,y) are reflected on the y axis the image coordinates are (-x,y) thus repeating this will form the second image coordinates as (x,y).

Determine the zeroes of 10x2−5=35
OLEGan [10]

Answer:

x = +2, x = -2

Step-by-step explanation:

The equation to solve in this problem is

10x^2-5=35

The first step we do is to subtract 35 on both sides of the equation, so we get:

10x^2-5-35=0\\10x^2-40=0

Now we simplify the equation by dividing both terms by 10:

\frac{10x^2-40}{10}=0\\x^2-4=0

Now we observe that the term on the left is the difference between two squares, so it can be rewritten using the property:

a^2-b^2=(a+b)(a-b)

Where here,

a = x

b = 2

So we can rewrite the equation as:

x^2-4=0\\(x+2)(x-2)=0

And this equation is zero when either one of the two factors is zero, so the two solutions are:

x+2=0\rightarrow x=-2\\x-2=0 \rightarrow x=+2
