Can someone please solve
pentagon [3]

Answer:

78

Step-by-step explanation:

Evaluate 6 (2 x^2 - 5) where x = -3:

6 (2 x^2 - 5) = 6 (2×(-3)^2 - 5)

Hint: | Evaluate (-3)^2.

(-3)^2 = 9:

6 (2×9 - 5)

Hint: | Multiply 2 and 9 together.

2×9 = 18:

6 (18 - 5)

Hint: | Subtract 5 from 18.

| 1 | 8

- | | 5

| 1 | 3:

6×13

Hint: | Multiply 6 and 13 together.

6×13 = 78:

Answer:  78

Find the average of e^-x over [0,3]
yaroslaw [1]

The average value of a continuous function <em>f(x)</em> over an interval [<em>a</em>, <em>b</em>] is given by the integral,

\displaystyle \frac1{b-a}\int_a^b f(x)\,\mathrm dx

Compute the integral for <em>f(x)</em> = <em>e</em> ⁻ˣ over [0, 3] :

\displaystyle \frac1{3-0}\int_0^3e^{-x}\,\mathrm dx=\frac13(-e^{-x})\bigg|_0^3=\frac13(-e^{-3}-(-e^{-0})) = \frac13 \left(1-\frac1{e^3}\right) = \boxed{\frac{e^3-1}{3e^3}}

zimovet [89]

Answer:

Reinaldo es ingeniero

Step-by-step explanation:

Por los datos del problema sabemos que Jeferson es casado. También sabemos que el profesor se casará pronto, así que:

Jeferson no es profesor

Reinaldo debe tomar el metro para visitar al médico, así que no es vecino de ninguno. Como el médico y el profesor son vecinos, entonces Reinaldo no es médico ni profesor, asi que

Reinaldo es ingeniero

Podemos saber además que si Jeferson no es profesor (ya demostrado) ni tampoco es ingeniero, entonces

Jeferson es médico

Por descarte, Yasir es profesor
