Give the equation for a circle with the given center and radius. Center at (2, -9), radius = 3

Mathematics
1 answer:
olga2289 [7]2 years ago
8 0

Answer:

B

Step-by-step explanation:

The standard form of the equation of a circle is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (2, - 9) and r = 3, thus

(x - 2)² + (y - (- 9))² = 3², that is

(x - 2)² + (y + 9)² = 9 → B

Use vieta's theorem to solve the problems.
Mnenie [13.5K]

Using Vieta's Theorem, it is found that c = 72.

<h3>What is the Vieta Theorem?</h3>
  • Suppose we have a quadratic equation, in the following format:

y = ax^2 + bx + c

  • The roots are p and q.

The Theorem states that:

p + q = -\frac{b}{a}

pq = \frac{c}{a}

In this problem, the polynomial is:

x^2 - 17x + c

Hence the coefficients are a = 1, b = -17.

Since the difference of the solutions is 1, we have that:

p - q = 1

p = 1 + q

Then, from the first equation of the Theorem:

p + q = -\frac{b}{a}

1 + q + q = 17

2q = 16

q = 8

p = 1 + q = 9

Now, from the second equation:

pq = \frac{c}{a}

72 = c

c = 72

Suppose the sales tax rate is 5% on a $1300 tv how much is is the amount of tax?
shepuryov [24]

Answer:

Therefore, amount of tax is $65.

Step-by-step explanation:

Amount of tax = Tax% of $1300

Amount of tax = 5% of $1300

= (5/100) of $1300

= (1/20) of $1300

= $130/2

= $65
