Answer:

(D) 30 degrees

Step-by-step explanation:

An inscribed angle is an angle formed by two chords in a circle which have a common endpoint.

Theorem(Inscribed Angles Conjecture I): In a circle, the measure of an inscribed angle is half the measure of the central angle with the same intercepted arc.

By the theorem above and from the attached diagram,

Inscribed Angle p =Half of 60 degrees

$\angle p=0.5 X 60^\circ\\p=30^\circ$

The correct option is D.

The surface area of a sphere is given by

$S = 4\pi r^2$

We deduce

$r = \sqrt{\dfrac{S}{4\pi}}$

So, in your case, the radius is

$r = \sqrt{\dfrac{100\pi}{4\pi}}=\sqrt{25}=5$

The volume of a sphere is given by

$V=\dfrac{4}{3}\pi r^3$

So, we have

$V = \dfrac{4}{3} \pi 5^3 = \dfrac{500}{3}\pi$

I am a quadrilateral with 2 pairs of opposite sides that are parallel, 2 pairs of sides that are of equal length,and 4 right ang

Ludmilka [50]

Answer:

Rectangle

Step-by-step explanation:

The shape is of a rectangle who has got two pairs of opposite sides that are parallel and two pairs of sides that are of equal length of each other with all the four right angles that makes up total angle of 360 degrees in total. It can be acquired that the area which is equal to length multiply by breadth.

Calculation,

A length of the rectangle is equal to each other,

Assuming it to be 3cm,

Breadth of it is equal to each other,

Assuming that to be 2cm,

Length x Breadth = Area

3 x 2 = 6cm to the power 2.

Write the opposite polynomial for -3x ^3+12x-4

ValentinkaMS [17]

Answer:

3x³ - 12x + 4

Step-by-step explanation:

The opposite of a polynomial P is -P.

You find the opposite of P by multiplying it by -1.

P = -3x³ + 12x - 4

-P = (-1)( -3x³ + 12x - 4) Distribute -1 to each term

= (-1)(-3x³) + (-1)(12x) - (-1)(4) Multiply each coefficient by -1

= 3x³ + (-12)x - (-4)

= 3x³ - 12x + 4
