Answer:
3.71 cm
Step-by-step explanation:
Hi there!
Area of a circle equation:
where r is the radius
Plug in the area 43.25 cm²

Divide both sides by π to isolate r²

Take the square root of both sides to isolate r

Therefore, the length of the radius rounded to 2 decimal points is 3.71 cm.
I hope this helps!
Since x represents the number of students, and y represents the number of adult chaperones (and x does not include y), the best answer is A, that there are x = 50 students on the field trip, and they are accompanied by y = 5 chaperones.
Note the difference with choice c, which says that 50 is the total (45 students, 5 adults).
Answer:
.
Step-by-step explanation:
According to the Rational Root Theorem, the potential roots of a polynomial are
where, p is a factor of constant and q is a factor of leading term.
The given polynomial is

Here, 9 is the leading term and 7 is constant.
Factors of 9 are ±1, ±3, ±9.
Factors of 7 are ±1, ±7.
Using rational root theorem, the rational or potential roots are

Therefore, the potential root of f(x) are
