Find the altitude of an equilateral triangle whose perimeter is 18

Mathematics
1 answer:
Rainbow [258]2 years ago
5 0

Answer:

3√3 units

Step-by-step explanation:

We are asked to find the altitude of the equilateral triangle whose perimeter is 18 . Firstly let us find the side of the∆.

\rm \implies a + a + a = 18 \\\\\rm\implies 3a = 18  \\\\\rm\implies a = 6

Now we know that in a equilateral triangle , the altitude of the triangle with side length a is ,

\rm\implies Altitude =\dfrac{\sqrt3}{2} a

Plug in the value of a that is 6 , we will get ,

\rm\implies Altitude =\dfrac{\sqrt 3}{2} a  \\\\\rm\implies Altitude =\dfrac{ \sqrt3}{2}\times 6  \\\\\rm\implies Altitude = \sqrt3 \times 3  \\\\\rm\implies\boxed{ \bf Altitude = 3\sqrt3 \ units }

Find the inflection point of the function of f(x) = x³ -6x² +12x
Wewaii [24]

Points of inflections are zeroes of the second derivative. We have:

f(x)=x^3-6x^2+12x\implies f'(x)=3x^2-12x\implies f''(x)=6x-12

So, the second derivative equals zero if and only if

f''(x)=0\iff 6x-12=0 \iff 6x=12 \iff x=2

So, this is the only point of inflection of this function.

1. Solve the equation using the zero-product property.<br> -x(5x – 4) = 0
Oxana [17]

Answer:

x = 0, 4/5

Step-by-step explanation:

The zero-product property states that if the product of a and b is zero, then either a = 0, b = 0, or both terms equal zero

  • Here our a term is -x and our b term is (5x - 4)
  • Setting each term equal to zero and solving for x we get
  • -x = 0 → x = 0
  • 5x - 4 = 0 → 5x = 4 → x = 4/5

Guyssss I’m confuseddddd
rosijanka [135]

Answer:

0 > -5

Step-by-step explanation:

9w - 4w + 6 > 1 + 5w

add the similar variables

5w + 6  > 1 + 5w

subtract  6 from both sides

5w + 6  > 1 + 5w

       -6     -6

5w > 5w - 5

simplify

5w > 5w -5

subtract 5 w from both sides

5w > 5w -5

-5w    -5w

simplify

= 0 > -5
