Answer:

The first one

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan30° = $\frac{opposite}{adjacent}$ = $\frac{AC}{BC}$ = $\frac{b}{8}$

Multiply both sides by 8

8 × tan30° = b, that is

b = 8tan30°

Basically, take the union of both domains g(x)=x/(1-x) 1-x=0 1=x x=1 is restricted because it makes you divide by 0 f(x)=(1-x)/(1+x) 1+x=0 x=-1 x=-1 is restricted because it makes you divide by 0 domain is all real numbers except -1 and 1

A certain microprocessor requires either 2, 3, 4, 8, or 12 machine cycles to perform various operations. Twenty-five percent of

myrzilka [38]

Answer:

The average number of machine cycles per instruction for this microprocessor is 5.8.

Step-by-step explanation:

To find the average number of machine cycles per instruction for this microprocessor, we multiply each number of cycles for it's relative frequency.

We have that:

25% require 2 cycles.

20% require 3 cycles.

17.5% require 4 cycles.

12.5% require 8 cycles.

25% require 12 cycles.

So the average number is:

$M = 0.25*2 + 0.2*3 + 0.175*4 + 0.125*8 + 0.25*12 = 5.8$
