Mathematics
1 answer:
Softa [21]2 years ago
6 0

Answer:

100.544m

Step-by-step explanation:

Surface area of a cylinder = 2pie x rh + 2pie x r² where pie = 3.142

Therefore, (2x3.142x2x6) + (2x3.142x2²) =100.544m

Find the value of x that will make A||B.<br> 5x + 9<br> A<br> B<br> 6x-2<br> X =<br> [?]<br> Enter
givi [52]

Answer:

x = 11

Step-by-step explanation:

Given

Parallel lines A and B

Required

Find x

For A and B to be parallel, then 5x + 9 and 6x - 2 are alternate interior angles

And alternate interior angles are always equal

This means that

5x + 9 = 6x - 2

Collect like terms

5x - 6x = -2 -9

-x = -11

Multiply both sides by -1

-1 * -x = -11 * -1

x = 11

Find a formula for the inverse of the function. f(x)=1-2/x^3.
Elena-2011 [213]
       f(x) = 1 - ²/ₓ₃
          y = 1 - ²/ₓ₃
          y = 1 - ²/ₓ₃
      y - 1 = ⁻²/ₓ₃
      x - 1 = -2/y³
 y³(x - 1) = -2
         y³ = ⁻²/ₓ₋₁
          y = ∛⁻²/ₓ₋₁
          y = -∛(2x² - 4x + 2)/x - 1
      f⁻¹(x) = -∛(2x² - 4x + 2)/x - 1

Esta é a trigonometria . Se você desenhar uma linha a partir do topo da casa de luz para o barco, você terá a hypotonuse de um triângulo. Um truque é lembrar que este é um triângulo especial. É um triângulo 30-60-90 , que tem propriedades especiais mostradas na fixação abaixo . por isso sabemos que o lado adjacente que não é o hyposonuse é x√3 . Agora sabemos que x<span>√3 = 20
Solve for x.
x</span><span>√3=20
divide both sides by </span><span>√3.
x=20/(</span><span><span>√3)
</span>Try not to have square roots (</span><span><span>√)</span> in denomenator so multiply top and bottom by </span><span>√3 and get
