If the radius of a circle is 10 feet, how long is the arc subtended by an angle measuring 81°? a) 9π feet b) 2 9 π feet c) 9 5 π feet d) 9 2 π feet

Option D.

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference of a circle is equal to

we have

substitute

step 2

we know that

360° subtends the complete circle of length 2πr.

so

By proportion

Find the length of the arc subtended by an angle measuring 81°

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
