0 1

Explicação passo a passo:

Das opções fornecidas:

Todas as opções atendem à condição de uma matriz quadrada, pois todas têm o mesmo número de linhas e colunas (2 * 2)

Para ter uma matriz diagonal, todas as entradas fora da diagonal principal serão Zero.

Por outro lado, a matriz de identidade é um tipo especial de matriz quadrada com uma ao longo da diagonal principal.

Indo por essas condições apenas a matriz (b); atende às três condições.

A half-circle is joined to an equilateral triangle with side lengths of 12 units. What is the perimeter of the resulting shape?
krek1111 [17]

Answer:

P = 42.84  cm

Step-by-step explanation:

A half-circle is joined to an equilateral triangle with side lengths of 12 units.

We need to find the perimeter of the resulting shape.

The perimeter of the half cirle is πr.

The diameter of the circle is 12. It means radius is 6 units.

An equilateral triangle has 3 equal sides. So, perimeter of the triangle is given by :

P = πr  + 12 +12

= 3.14(6) + 24

= 42.84  cm

Hence, the perimeter of the resulting shape is 42.84  cm.

Evaluate the expression without using a calculator<br><br> Tan(arccos3/4)
julia-pushkina [17]

9514 1404 393

Answer:

  (√7)/3

Step-by-step explanation:

The relationship between tangent and cosine is ...

  tan(α) = √(1/cos(α)² -1)

The cosine of the angle is given as 3/4, so the tangent is ...

  tan(arccos(3/4)) = √(1/(3/4)² -1) = √(16/9 -1) = √(7/9)

  tan(arccos(3/4)) = (√7)/3
