The given expression is
81x²y³ + z

When x=3, y=4, z=19, then
81x²y³ + z
= 81*(3²)*(4³) + 19
= 81*9*64 + 19
= 46,675

Answer:  D  46,675

Si un triángulo tiene una hipotenusa de 15 cm y un cateto que mide 12 cm, ¿cual es la longitud del otro cateto?
BartSMP [9]

Answer:

   

9cm

Explicación:

El teorema de pitagoras nos dice que la hipotenusa al cuadrado es igual a la suma de los catetos al cuadrado:

c^{2} =a^{2} + b^{2}

Donde c es la hipotenusa y a  y b son los catetos.

Por lo cual, podemos reemplazar c por 15cm y a por 12cm :

15^{2} =12^{2} +b^{2}

Finalmente , debemos resolver la ecuación para b, así que b es igual a :

225=144+b^{2} \\225-144=144+b^{2} -144\\81=b^{2} \\\sqrt{81} =b\\9=b

Por lo tanto, la longitud del otro cateto es 9 cm

Help me please. This is my last question
Crazy boy [7]

Answer: D. 44

Step-by-step explanation:

Here, we need to know the concept of trigonometry.

  • Sine (sin) = Opposite/Hypotenuse = O/H
  • Cosine (cos) = Adjacent/Hypotenuse = A/H
  • Tangent (tan) = Oppostie/Adjacent = O/A

-----------------------------------------------------------------------------

Given

- The adjacent side of angle x and the hypotenuse.

- We are going to use Cosine.

<u>Solve</u>

cos (x) = 15/21

       x  = cos⁻¹ (15/21)

       x  ≈ 44

Hope this helps!! :)
