Answer:

The radius and the diameter of the circle are 11 cm and 22 cm respectively.

Step-by-step explanation:

The radius of a circle is a line segment extending from the center of a circle or sphere to the circumference or bounding surface, while the diameter of a circle is a straight line passing from side to side through the center of a body or figure, commonly a circle or sphere. Since the diameter goes entirely across the circle while passing through the midpoint - or center - of a circle and the radius only goes from the edge to the midpoint, that means the diameter is twice as big as the radius. In this example, the radius is already given to you, which is 11 cm, based on the image. Using this, you can figure out the diameter of that circle would be 11 * 2 or 22 cm. So the radius of the circle is 11 cm, while the diameter of the circle is 22 cm.

Three vertices of a square are given. Find the coordinates of the fourth vertex. (_5, 5), (_5, 2), (_2, 2)
Katena32 [7]
<span>If you plot these points, you can probably see where the missing square corner is. But you might also notice that a square's sides are equal length. Between the first two coordinate pairs, the only thing that changes is the y value, from 5 to 2, or a change of 3. Between the 2nd two coordinate pairs, only the x value changes, from -5 to -2, or a change of 3. So it looks like the sides are 3 units long. The fourth coordinate should be 3 units away on the x coordinate from one "neighbor" and 3 units away on the y coordinate from its other neighbor. But it really would help to sketch it out so you don't get mixed up.

Find dy/dx for y=log (tan2x)
nekit [7.7K]

Answer:

\frac{dy}{dx} = \frac{2}{sin2x cos2x}

Step-by-step explanation:

y = log (tan 2x)

Applying chain rule:

\frac{dy}{dx} = \frac{d}{dx} (1st function) . \frac{d}{dx} (2nd function). \frac{d}{dx}(3rd function)

\frac{dy}{dx} = \frac{d}{dx} log(tan 2x) . \frac{d}{dx} tan2x. \frac{d}{dx} 2x

\frac{dy}{dx} = \frac{1}{tan2x} \times sec^{2}2x \times 2

\frac{dy}{dx} = \frac{2sec^{2}2x }{tan2x}

Now since sec^{2}x = \frac{1}{cos^{2}x } \ and\ tanx = \frac{sinx}{cosx}

∴ \frac{dy}{dx} = \frac{2cos2x }{sin2x cos^22x}

∴ \frac{dy}{dx} = \frac{2}{sin2x cos2x}

Angle A and Angle B are complimentary angles. If the measure of Angle A is 42 find the measure of angle B
deff fn [24]

Here's my step-by-step explanation:

@Jdoe0001 already gave you a hint in the comment section, and that's a real giveaway, but I'll expand on the hint.

Complimentary angles add up to 90°, and A and B are complimentary, then A+B = 90°. A proof.

Substitute. 42° + B = 90°.

B = 90° - 42°

B = 48°

Hope this helps!
