Answer:
15cm
Step-by-step explanation:
Let x be the arc circumference.
The circumference of a circle usually subtends to 360°, that is, one complete revolution is 360°.
#Given the arc angle as 45° and the circumference as 120cm, the arc circumference can be obtained as:
#Apply proportions to find x:

Hence, the arc circumference is 15cm
53/125 is the simplest form for this question.

<span>the y-intercept will be

</span>the standard line equation is y = mx + b, where y is the y point, x is the x point, m is the slope, and b is the y-intercept.
to get the y intercept, we need to transform into the line equation, and caculate out b.
3x + 5y = 8
so 5y = 8 -3x
then y = <span>

- <span>

x
which means that <span>

= the y intercept.</span></span></span>
If the roots are 1 and 3, the factors of this quadratic are (x-1) and (x-3).
The polynomial is x^2 - 4x + 3.
If you were supposed to write a polynomial based upon all four given roots, then:
Looks as tho' you have four distinct roots. The 4th order polynomial with these roots is f(x) = (x-1)(x-3)(x-7)(x-2). Multiply this out, combine like terms and then arrange the terms in descending order by powers of x.
