Answer: The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.

The formula for calculating the radius is different from calculating the diameter

Find radius

r= diameter/ 2

Radius is half of a diameter

While diameter is

d=2r

Nostrana [21]

Answer:

$\sqrt{2}$ - 1

Step-by-step explanation:

h = 20 – 5t2 = 15 -> t = 1

h = 20 – 5t2 = 10 -> t = $\sqrt{2}$

What is -2 sqrt 50 - sqrt 125 in simplest radical form

Gnoma [55]

Answer:

- 10√2 - 5√5

Step-by-step explanation:

- 2√50

√50 = √( 2 x 5 x 5 ) = 5√2

- 2√50

= - 2 x 5√2

= - 10√2

- √125

= - √( 5 x 5 x 5 )

= - 5√5

- 2√50 - √125

= - 10√2 - 5√5

Which of the following are identities? Check all that apply. A. cot2x + 1 = csc2x B. tan2x = 1 - sec2x C. sin2x = 1 + cos2x D. s

kirill115 [55]

I'll assume those are squares. We know D is an identity:

$\sin^2 x + \cos ^2 x = 1$

Dividing through by $\sin ^2 x$

$1 + \cot^2 x = \csc^2 x$

That's A.

Dividing the original through by $\cos ^2 x$

$\tan^2 x + 1 = \sec^2 x$

Not quite B, wrong sign on tangent.

C has the wrong sign on cosine squared as well.

Identities: A & D
