It’s would be 160 km since 160/80x60=120 min and 160/120x60=80min

Answer:

Step-by-step explanation:

a (2³)² = 2³ˣ² = 2⁶

b (7⁰)¹ = 7⁰ˣ¹ = 7⁰ = 1

c (5⁶)³ = 5⁶ˣ³ = 5¹⁸

d (6²)⁴ = 6²ˣ⁴ = 6⁸

e (8³)⁴ = 8³ˣ⁴ = 8¹²

f (4³)² = 4³ˣ² = 4⁶

g (9¹)² = 9¹ˣ² = 9² = 81

h (3⁷)² = 3⁷ˣ² = 3¹⁴

i (10²)³ = 10²ˣ³ = 10⁶

j (11²)⁴ = 11²ˣ⁴ = 11⁸

Si f(x) es igual a raiz de x al cuadrado menos 16 determinar f(5),f(4),f(6),f(3)

Nadusha1986 [10]

Aplicando la función, los valores numéricos son :

$f(5) = -11$

$f(4) = -12$

$f(6) = -10$

$f(3) = -13$

La función es dada por:

$f(x) = (\sqrt{x})^2 - 16 = x - 16$

Para los valores numéricos, reemplazamos x, luego:

$f(5) = 5 - 16 = -11$

$f(4) = 4 - 16 = -12$

$f(6) = 6 - 16 = -10$

$f(3) = 3 - 16 = -13$

6 - 2x = 6x - 10x + 4

yarga [219]

$6 - 2x = 6x - 10x + 4$

$6 - 2x = - 4x + 4$

$6 = - 4x + 4 + 2x$

$6 = - 2x + 4$

$- 2x + 4 = 6$

$- 2x = 6 - 4$

$- 2x = 2$

$x = \frac{ \: \: \: 2}{ - 2}$

$x = - 1$

Therefore , the value of x = -1

Which of the trigonometric ratios has a value that is undefined?

FinnZ [79.3K]

Answer:

$\tan \left(\frac{\pi }{2}\right)$

Step-by-step explanation:

We know that tan(x) is defined as sin(x)/cos(x):

$\tan \left(\frac{\pi }{2}\right),\\\sin \left(\frac{\pi }{2}\right)=1,\\\cos \left(\frac{\pi }{2}\right)=0,\\\\$

$\tan \left(\frac{\pi }{2}\right) = 1/0 \\$

1/0 is undefined as 0 is in the denominator
