Helpppppppppppp plzzzzzzzzzzzzzzzzzzz
ZanzabumX [31]

Answer:

Step-by-step explanation:

\left[\begin{array}{ccc}7&31\\142&19\end{array}\right] = 7(19) - 142(31) = <em>- 4269</em>

\left[\begin{array}{ccc}7&11&21\\55&-8&2\\-16&-1&-9\end{array}\right] = 7(- 8)(- 9) + 11(2)(- 16) + 21(55)(- 1) - 21(- 8)(- 16) - 7(2)(- 1) - 11(55)(- 9) = <em>1768</em>

\left[\begin{array}{ccc}9.07&6.02&2.01\\-30.7&2.5&3.5\\3.55&-1.1&2.35\end{array}\right] = 9.07(2.5)(2.35) + 6.02(3.5)(3.55) + 2.01(- 30.7)(- 1.1) - 2.01(2.5)(3.55) - 9.07(3.5)(- 1.1) - 6.02(- 30.7)(2.35) = <em>647.3561</em>

F(x^2) = x^2 - 3

5f(x^2) = 5x^2 - 15 = 2x - 8

Placing all the terms on the left side, we get:

5x^2 - 2x - 7 = 0 which factorises to

(5x - 7)(x + 1) = 0

So, x = 7/5 or x = -1

But x is non-negative, so x = 7/5 = 1 2/5

C is the answer.

Un observador se encuentra en un faro al pie de un acantilado a 687m sobre el nivel del mar, desde este punto observa un barco c
maks197457 [2]

La distancia entre el barco y la base del acantilado es 291.61 metros.

<h3>¿Como calcular la distancia?</h3>

Podemos pensar en esta situacion como en un triangulo rectangulo. Uno de los catetos mide 687 metros, que es la altura del acantilado.

Y conocemos el angulo al que ese cateto es adjacente, que mide 23 grados.

La distancia entre la base del acantilado y el barco será el otro cateto del triangulo rectangulo.

Entonces podemos usar la relación:

tan(a) = (cateto opuesto)/(cateto adjacente)

Reemplazando lo que sabemos:

tan(23°) = D/687m

tan(23°)*687m = D = 291.61m

La distancia entre el barco y la base del acantilado es 291.61 metros.
