Answer:
Step-by-step explanation:
we have
----> The degree of this polynomial is 1 (linear equation)
Remember that
The zero of the polynomial is the value of x when the value of f(x) is zero
so
For f(x)=0
solve for x
----> the zero of the polynomial or x-intercept
Answer:
250
Step-by-step explanation:
52%-> 130
100%-> 250
For this case we have the following equation:
r = 9 sin (θ)
In addition, we have the following change of variables:
y = r * sine (θ)
Rewriting the equation we have:
r = 9 sin (θ)
r = 9 (y / r)
r ^ 2 = 9y
On the other hand:
r ^ 2 = x ^ 2 + y ^ 2
Substituting values:
x ^ 2 + y ^ 2 = 9y
Rewriting:
x ^ 2 + y ^ 2 - 9y = 0
Completing squares:
x ^ 2 + y ^ 2 - 9y + (-9/2) ^ 2 = (-9/2) ^ 2
Rewriting:
x ^ 2 + 1/4 (2y-9) ^ 2 = 81/4
4x ^ 2 + (2y-9) ^ 2 = 81
Answer:
The Cartesian equation is:
4x ^ 2 + (2y-9) ^ 2 = 81
The paper clip's length, as shown in the picture, is closest to C. 2 inches.
