tan(asin(-sqrt(3)/2)) = -1.73205080757

1) 4 / sqrt(32) =

4 / sqrt(4*8) =

4 / [sqrt(4)*sqrt(8)]=

4 / [2*sqrt(8)] =

2/ sqrt(8) * [sqrt8/sqrt8] =

2sqrt8/8 =

sqrt8/4.

2) 5 / sqrt(48) = 

5 / sqrt(16*3) = 

5 / [sqrt(16)*sqrt(3)] =

5 / [4*sqrt(3)] =

5 / 4sqrt3 * [sqrt3 / sqrt3] =

5sqrt3 / 12.

3) 3sqrt5 / sqrt(25) =

3sqrt5 / 5.

4) 3sqrt24 / sqrt(2) =

3*sqrt(2)*sqrt(12) / sqrt(2) =

3sqrt(12).

A = (b1/2 + b2/2)h

1) A/h = b1/2 + b2/2 --> A/h - b2/2 = b1/2 --> 2A/h - 2b2/2 = b1 --> b1 = 2A/h - (b2).

2) A/h = b1/2 + b2/2 --> A/h - b1/2 = b2/2 --> 2A/h -2b1/2 = b2 --> b2 = 2A/h - (b1).

3) 2A = (b1 + b2)h --> 2A/(b1+b2) = h.

No puedes poner coseno a la menos 1, solo numeros como cos(5) pero no cos(<5).

Primero, haga multiplicacion: 3*3 = 9 -> 10+10+5+2+9+6 = 42.

7/2 - 5/6

Haga el denominator el mismo --> 7/2 -> multiplicar por 3 -> 21/6

Ahora: 21/6 - 5/6 = 16/6.

29 / 45 --> No podemos simplificar esto porque 29 es un numero prime (solo 1 y 29 son factores).

Haha, that's funny! 

Here's a ruler:

Ohh yes, yours makes more sense Phill...was wondering how come there weren't any direct square roots for the 2nd question. 

Sorry, not sure if it is available on the calculator here but for graphing calculators: Hit Mode --> Find seq (near fun par pol) --> Then, hit the "Y =" button --> enter your information.
