Answer:

The third option is correct: 5.7 units, M(7, 5, 2.5).

Step-by-step explanation:

The distance is √ [(9-5)^2 + (7-3)^2 + (3-2)^2 ]

= √ (16 + 16 + 1)

= √33

= 5.7.

The mid point = (9+5)/2 , (7+3)/2, (3+2)/2

= (7, 5, 2.5).

Answer: 6.3093

Step-by-step explanation:

$3^{\frac{x}{5}} = 4$

$ln3^{\frac{x}{5}} = ln4$

$\frac{x}{5} ln3 = ln4$

xln3 = 5ln4

$x = \frac{5ln4}{ln3}$

x = 6.3093

Answer: 5, 3, $\frac{1}{5}$ , D

Step-by-step explanation:

a) x ≤ 0 so, f(-5) = | -5 | = 5

x ≤ 0 so, f(-3) = | -3 | = 3

x > 0 so, f(5) = $\frac{1}{5}$

b) graph D

Consider this equation:

alexandr1967 [171]

Answer:

we are given the function –2x – 4 + 5x = 8 and is asked in the problem to solve for the variable x in the function. In this case, we can first group the like terms and put them in their corresponding sides:

-2x + 5x =8+4

Then, do the necessary operations.

3x = 12

x = 4.

The variable x has a value of 4.
