Answer:

B is correct

Step-by-step explanation:

These are Absolute Value expressions. (How far from 0 on the number line) So disregard negative or positive signs. The only true statement would be 2<4.

Answer:

Step-by-step explanation:

B because the little lines that the numbers are between means absolute vale which means even if its negative its still positive as long as the negative sign is in the little lines. b= 2<4 which is correct

X times 3+6 when X equals four

Gekata [30.6K]

Step-by-step explanation:

4 x 3 + 6

12 + 6

= 18

4 x (3+6)

4 x 9

= 36

depends whether the 3+6 is in brackets :)

When will n(A∩B)=0? Explain and give an example.

andrew11 [14]

Answer:

Two sets are called disjoint if they have no elements in common. For example:

The sets S = { 2, 4, 6, 8 } and T = { 1, 3, 5, 7 } are disjoint.

Another way to define disjoint sets is to say that their intersection is the empty set,

Two sets A and B are disjoint if A ∩ B = 0.

In the example above,

S ∩ T = ∅ because no number lies in both sets.

When Kimchi is made, it is initially fermented for the first 3 days at a temperature of 70 degrees Fahrenheit and then immediate

svet-max [94.6K]

The given temperatures of 70 °F, 50 °F, and 35 °F, at the given 3, 3, and

6 days give the following step function;

$\begin{cases}f(x) = 70^{\circ } & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}$

Please find attached the graph of the step function?

<h3>How can the step function be written?</h3>

The temperature at it is fermented in the first three days = 70 °F

From day 3 to 6 the temperature = 50 °F

From day 6 to day 12, the temperature at which it is kept in the freezer = 35 °F

The step function is therefore;

$\begin{cases}f(x) = 70^{\circ } & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}$

The graph of the above function created with MS Excel is attached

Batman took a bicycle trip. In all, he traveled 6 hours at a rate of 28 mph. What was his total distance ?

Mice21 [21]

Distance=speed x time
so it would be 28 x 6=168
