Polynomial is an expression consisting of indeterminates and coefficients, also mathematical operations. option 1 is a complete list of the roots of the polynomial function.

Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

As it is given that a polynomial function f(x) is a fourth-degree polynomial. Therefore, it must have 4 roots. Now if we check all the options for the possible list of roots of f(x).

Looking at the options,

Option 1. 3,4,5,6 can be the complete list for polynomial function f(x).

Now, Option 2 and option 3 cannot be the complete list of the roots for f(x) as it has one complex root and complex roots always occur in pairs.

Further, Option 4 cannot be the complete list for f(x) as complex roots occur in pairs and they conjugates but conjugate of 5+i is 5-i(which is not given), not -5+i.

Hence, option 1 is a complete list of the roots of the polynomial function.

Answer:

[tex]\displaystyle \frac{\sqrt{2} + \sqrt{6}}{4}[/tex]

Explanation:

If you recall the unit circle [from the polar graph], you would have no trouble at all figuring this out, but sinse you have trouble, do not worry about it. So, here is what you should have realised:

[tex]\displaystyle \boxed{\frac{\pi}{2}} = \frac{6}{12}\pi[/tex]

If you did not notise, [tex]\displaystyle \frac{7}{12}\pi[/tex]is just [tex]\displaystyle \frac{\pi}{12}[/tex]more than [tex]\displaystyle \frac{\pi}{2},[/tex]which means the exact value could possibly have a 4 in its denominatour [which obviously also has a desimal value] or could be irrational [values that cannot be written as fractions]. In this case, according to the unit circle, you will have a fraction, and that will be this:

[tex]\displaystyle \frac{\sqrt{2} + \sqrt{6}}{4}[/tex]

It is all about memorisation of the unit circle, which I know is difficult, but you will get used to it soon.

*Now, if you had to find [tex]\displaystyle cos\:\frac{7}{12}\pi,[/tex]then the exact value would be the OPPOCITE of the exact value of [tex]\displaystyle sin\:\frac{7}{12}\pi,[/tex]which is [tex]\displaystyle -\frac{\sqrt{2} + \sqrt{6}}{4},[/tex]because you would be crossing into the second quadrant where the x-coordinates are negative, accourding to both the cartesian and polar graphs.

Answer:

(a) 28π cm

(b) 88 cm

Step-by-step explanation:

Part A — Give an exact answer in terms of π.

To find circumference of a circle, our formula is:

[tex]\displaystyle \large{C=2\pi r}[/tex]

Where:

Radius is,the line segment or value from center to one of endpoints. Our radius is given as 14 cm in the shown attachment.

Henceforth, our circumference is:

[tex]\displaystyle \large{C=2\pi \cdot 14}\\\displaystyle \large{C = 28\pi}[/tex]

So for part A, the circumference is 28π cm.

Part B — Use π ≈ 22/7 and express your answer as a fraction in lowest terms.

For this part, use the circumference that we solved from part A:

[tex]\displaystyle \large{C=28\pi}[/tex]

Substitute π = 22/7 in.

[tex]\displaystyle \large{C \approx 28\cdot \frac{22}{7}}\\\displaystyle \large{C \approx 4\cdot 22}\\\displaystyle \large{C \approx 88 \ cm}[/tex]

Henceforth, the circumference in Part B is approximately 88 cm.

As LHS not equal to RHS

Answer:

5 units

Step-by-step explanation:

The base of a triangular prism is the area of the triangle, i.e. the area of the cross-section.

The "height" of this triangular prism is the depth of the shape (the wording of the question is confusing!).

Volume of the prism = area of cross-section × height

                                  = area of triangle × depth of shape

If the volume of the prism is 130 units³ and the area of the base is 26 units², substitute these values into the above formula to find the height:

⇒ 130 = 26 × height

⇒ height = 130 ÷ 26

⇒ height = 5 units

Answer: 10

Step-by-step explanation:

This problem depends on how you view "volume." In this case, I would view the volume as taking the surface area of the triangle, and then multiplying it by the small width it has. This will take the area and scale it across the entire volume. So, taking the area of a triangle and multiplying it by the width, you get:

[tex]Volume=Area*Width[/tex]

[tex]Volume=(\frac{1}{2} bh)*w[/tex]

We weren't given the actual base, but instead given the base area. That's easily undoable since the area of a rectangle is easy. Its simply, length times width.

[tex]Area=l*w[/tex]

We want the length here. The length of the rectangle is equivalent to the base of the triangle. Solve for the length of the rectangle to get:

[tex]Length=Base=Area/Width[/tex]

Lets plug in this "base" value into the formula for the volume of the figure:

[tex]Volume=(\frac{1}{2} (A/w)h)*w[/tex]

Plug in the given values. First though, you'll notice the width cancels giving:

[tex]Volume=(\frac{1}{2} Ah)[/tex]

[tex]130=(\frac{1}{2} 26*h)[/tex]

[tex]130=13h[/tex]

[tex]h=10[/tex]
