Answer:

Given

Step-by-step explanation:

Consider triangle ABD and triangle DCA,

AC=BD ( given that they are diameters)

Diameters of the same circle are equal

AD=AD (common side for both triangles)

<BAD= <CDA (angles in semicircles are 90°)

So since the right angle, hypotenuse and side are equal..

ABD is congruent to CDA

(Rhs congruence rule)

Hence proved..

Which is the simplified form of (9 c Superscript negative 9 Baseline) Superscript negative 3? 9 c Superscript 27 StartFraction 1
velikii [3]

Answer:

The correct option is B

B) (1/729)c²⁷

Step-by-step explanation:

Lets write it all in an understandable form.

The given expression is:

( 9c ⁻⁹ ) ⁻³

The given options are:

A)  9c²⁷

B) (1/729)c²⁷

C) 729c²⁷

D) 9/c²⁷

Lets find the solution. The given expression is:

( 9c ⁻⁹ ) ⁻³

Multiply the outer power -3 with each term inside the bracket. It can be rewritten as.

(9⁻³) ( c ⁽⁻⁹⁾⁽⁻³⁾)

A negative power can be converted into positive by taking it down in the denominator.

The multiplication (-9)(-3) results in 27.

The equation can be written as:

( 1/9³) ( c²⁷)

Where 9³ = 729

( 1/729)( c²⁷)

which is equal to option B

notsponge [240]

Answer:

y=-7x -2

Step-by-step explanation:

use formula to find the equation when you know slope and a point

it is: y-y1 = m(x-x1)

plug in values

y-(-30) = -7(x-4)

y+30 = -7x + 28

- 30 from both sides

y = -7x -2
