Write an equation of a circle whose center is (-3,2) and whose diameter is 10

1 answer:

5 0

The formula for a circle with center (h,k) and radius (r) is as follows:

(x – h)² + (y – k)² = r²

If the diameter of the circle is 10, we know that the radius of the circle must be equal to 5. Insert any known equations into the formula above:

(x – (-3))² + (y – 2)² = 5²

Simplify both sides of the equation:

(x + 3)² + (y – 2)² = 25

This is the equation of a circle with the given measurements.

I hope this helps!

Step-by-step explanation:

$\displaystyle y = Asin(Bx - C) + D$

According to this trigonometric function, −C gives you the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL:

$\displaystyle Phase\:[Horisontal]\:Shift → \frac{0}{\frac{1}{7}} = 0 \\ Period → \frac{2}{1}π = 2π$

Therefore we have our answer.

Extended Information on the trigonometric function

$\displaystyle Vertical\:Shift → D \\ Phase\:[Horisontal]\:Shift → \frac{C}{B} \\ Period → \frac{2}{B}π \\ Amplitude → |A|$

NOTE: Sometimes, your <em>vertical shift</em> might tell you to shift your graph below or above the <em>midline</em> where the amplitude is.

Find the percentage error |sinθ - θ|/sin(θ)*100 this approximation introduces for an angle of 0. 020 radians.

Elza [17]

Considering the given angle and the given formula, it is found that the percentage error for an angle of 0.02 radians is of 0.0067%.

<h3>What is the percentage angle for an angle?</h3>

For an angle $\theta$ , it is given by the following formula:

$P = 100\frac{|\sin{\theta} - \theta|}{\sin{\theta}}$

In this problem, the angle is of $\theta = 0.02$ , hence:

$P = 100\frac{|\sin{0.02} - 0.02|}{\sin{0.02}}$

$P = 0.0067$

The percentage error for an angle of 0.02 radians is of 0.0067%.

PLS HELP ME PLS I WILL MARK BRAINLIEST PLS

Vesnalui [34]

Answer:

AB = 25

Step-by-step explanation:

First things first, we know that these triangles are similar. Now let's find BC using the Pythagorean Theorem. BC = $5\sqrt5$ , this side is similar to the 5 side of the smaller triangle. That means each side of the larger triangle $\sqrt5$ times larger than the corresponding side on the small triangle. That means AB is $\sqrt5$ times larger than BC as well. So multiply BC by $\sqrt5$ get us the answer.
