8.

Show that (a ,a ) (-a,-a ) ( √3a, √3a ) are vertices of an equilateraltriangle.

Answer»

Step-by-step explanation:

a(a,a)

b(-a,-a)

c(√3a,√3a)

m(AB)=y2-y1/x2-x1

= -a-a/-a-a

= -2a/-2a

=1

m(bc)=y2-y1/x2-x1

= √3a+a/√3a+a

=1

m(AC)=y2-y1/x2-x1

= √3a-a/√3a-a

=1

therefore it is an equilateral TRIANGLE

Can anyone give me solution of my question fast i will mark brainlist answer

Answer»

Answer:

It is a proof.

Step-by-step explanation:

GIVEN Tⁿ = Sinⁿ X + Cosⁿ x

prove: 2 T₆ - 3 T₄ + 1 = 0

LHS =

= 2 (Sin⁶ x + Cos⁶ x) - 3 (Sin⁴ x + Cos⁴ x) + 1

= 2 (Sin² x + Cos² x) (Sin⁴ x - Sin² x Cos² x + Cos⁴ x)

- 3 (Sin⁴ x + Cos⁴ x) + 1

by USING the formula for a³ + b³ = (a+b)(a²-ab+b²)

= - 2 Sin² x Cos² x - Sin⁴ x - Cos⁴ x + 1

= - (Sin² x + COs² x )² + 1

= -1 + 1 = 0 = RHS

smendyka

Dec 24, 2017

See a solution PROCESS below:

Explanation:

First, we must find the height of the cone using the pythagorean Theorem. The Pythagorean Theorem states:

a2+b2=c2 where c is the hypotenuse of a right triangle.

In this case:

h2+r2=l2 or, substituting:

h2+82=102

h2+64=100

h2+64−64=100−64

h2+0=36

h2=36

√h2=√36

h=6

The formula for the volume of a cone is:

V=πr2h3

Substituting the radius from the problem and the the height we calculated gives:

V=π×(8CM)2×6cm3

V=π×64cm2×2cm

V=128πcm³
