A circle with center (4 -3) contain the point (9,-3). what is an equation of the circle

Mathematics
1 answer:
torisob [31]3 years ago
4 0

Answer:

\large\boxed{(x-4)^2+(y+3)^2=25}

Step-by-step explanation:

The equation of a circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have the center (4, -3) and the point on the circle (9, -3).

The length of radius is equal to the distance between a center and an any point on a circle.

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Susbtitute:

r=\sqrt{(9-4)^2+(-3-(-3))^2}=\sqrt{5^2+0^2}=\sqrt{5^2}=5

The center (4, -3) → h = 4, k = -3.

Finally we have:

(x-4)^2+(y-(-3))^2=5^2\\\\(x-4)^2+(y+3)^2=25

Houa bought 11 chicken wings for $23.10. How much does each wing cost?
MAXImum [283]

If Houa bought 11 chicken wings for $23.10.The cost of each wing will be $2.310.

<h3>What is an arithmetic operation?</h3>

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, Houa bought 11 chicken wings for $23.10.

We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group. Doing division is simple it is a type of operation in which we will distribute the items.

Suppose the cost of each wing is x.

x = $23.10 / 10

x =  $2.310

Thus, if Houa bought 11 chicken wings for $23.10.The cost of each wing will be $2.310.

What is the value of f if f + I-3 11/12 = 18
astra-53 [7]
Solve for f:(i - 47/12) + f = 18
(i - 47/12) + f = f + (-47/12 + i):
f + (-47/12 + i) = 18
Subtract -47/12 + i from both sides:
Answer:  f = 263/12 - i
