Find an equation of the circle that satisfies the given conditions. (Use the variables x and y.)
prohojiy [21]

Answer:

x^2 + y^2 = 52

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, (x_1,y_1) and (x_2,y_2). The distance between them is given by:

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

Equation of a circle:

The equation of a circle with center (x_0,y_0) and radius r has the following format:

(x - x_0)^2 + (y - y_0)^2 = r^2

Center at the origin;

This means that x_0 = 0, y_0 = 0

So

(x - x_0)^2 + (y - y_0)^2 = r^2

(x - 0)^2 + (y - 0)^2 = r^2

x^2 + y^2 = r^2

Passes through (4, 6)

The radius is the distance from this point to the center. So

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

r = \sqrt{(4-0)^2+(6-0)^2}

r = \sqrt{16+36}

r = \sqrt{52}

So

r^2 = 52

Then

x^2 + y^2 = r^2

x^2 + y^2 = 52

Find the derivative of the function <br> f(x) = √2^3 + ln(x^3) - 2x^3 - log_3(729) - 2/x^4
marysya [2.9K]

Applying the rules for the constant, logarithm and exponents, the derivative of the given function is of:

f'(x) = 3/x - 6x² - 8/(x^5).

<h3>What is the derivative of the function?</h3>

The function is given by:

f(x) = √2^3 + ln(x^3) - 2x^3 - log_3(729) - 2/x^4

The derivative of a sum is the sum of the derivatives, hence:

f'(x) = (√2^3)' + (ln(x^3))' - (2x^3)' - (log_3(729))' - (2/x^4)'

The derivative of a constant is of zero, hence:

  • (√2^3)' = 0.
  • (log_3(729))' = 0.

Hence:

f'(x) = (ln(x^3))' - (2x^3)' - (2/x^4)'.

The derivative of the logarithm is given by:

ln(h(x))' = (1/h(x)) x h'(x).

Hence:

(ln(x^3))' = 3x²/x³ = 3/x.

The derivative of the power of x is given by:

[x^n]' = nx^(n-1).

Hence:

  • (2x³)' = 6x².
  • (2/x^4)' = (2x^(-4))' = -8x^(-5) = -8/(x^5).

Hence the derivative of the function is given by:

f'(x) = 3/x - 6x² - 8/(x^5).
