Answer/s:

≈ 62.83 mm or 20π mm

Step-by-step explanation:

We can use the following formula to solve:

C = 2πr

C = 2π(10)

C ≈ 62.83 mm

-> You can also end up at 20π if you need an "exact" answer

Answer: 20pi mm

Step-by-step explanation:

The circumference of a circle is 2*pi*radius.

Therefore, the circumference is 2*pi*10mm = 20pi mm

Write the polynomial in standard form.
sp2606 [1]

The standard form is:

4x^5+3x^2+3

Degree = 5, leading coefficient=4

The 5th degree polynomial is:

Quintic function

it is a trinomial

<u>What is  standard form of a polynomial?</u>

When expressing a polynomial in its standard form, the greatest degree of terms are written first, followed by the next degree, and so on.

So, standard form is:

4x^5+3x^2+3

To find the degree of the polynomial, add up the exponents of each term and select the highest sum ( if there are more than 1 variable in single term) or highest power of variable

Degree = 5

In a polynomial, the leading term is the term with the highest power of x.

So, leading coefficient=4

The 5th degree polynomial is:

Quintic function

It has 3 terms. so, it is a trinomial

Identify the graph described by the function p(x)=x/10 for x=1,2,3,4
san4es73 [151]

Answer:

Graph A is correct

Step-by-step explanation:

p(x)= x/10

x= 1, 2, 3, 4

Plug in x  values in p(x)

when x=1 , then P(1) = 1/10

When x=2 , then P(2) = 2/10

When x=3 , then P(3) = 3/10

When x=4 , then P(4) = 4/10

In the graph y axis has 2/10 , 4/10 , 6/10...

1/10 lies between 0  and 2/10

3/10 lies between 2/10 and 4/10

Graph A is correct

For which intervals the graphs of the functions f(x) = x^3 + x^2 - 4x - 4 is positive
Nookie1986 [14]

Step-by-step explanation:

Consider a function

f

(

x

)

which is twice differentiable. The graph of such a function will be concave upwards in the intervals where the second derivative is positive and the graph will be concave downwards in the intervals where the second derivative is negative. To find these intervals we need to find the inflection points i.e. the x-values where the second derivative is 0.
