The operations between the data-sets are given as follows:

8. B ∩ A = {2,3}.

9. A ∩ U = {2,3,5,6}.

10. n(B) = {1,5,6,7}.

11. B x C = {{2,5}, {2, 1}, {2, 3}, {3, 5}, {3,1}, {3,3}}.

The intersection operation between two data-sets is the set that is composed by all the elements that belong to both data-sets. The intersection operation is represented by the symbol ∩.

From the data-sets in this problem, we have that:

The negation of a data-set is the set that contains all elements belonging to the universe set U but not to the data-set.

Hence, from the data-sets in this problem, we have that:

n(B) = {1,5,6,7}.

In which n(B) is the negation of set B.

The multiplication between two data-sets is given by all ordered pairs formed from the two data-sets.

Hence the solution for item 11 is given as follows:

B x C = {{2,5}, {2, 1}, {2, 3}, {3, 5}, {3,1}, {3,3}}.

The value of x in tan x = 4 over 9 is x = 23.9

The trigonometric equation is given as

tan x = 4 over 9

Rewrite the above equation properly

So, we have

tan(x) = 4/9

Evaluate the quotient

So, we have

tan(x) = 0.4444

Take the arc tan of both sides

x = 23.9

Hence, the value of x in tan x = 4 over 9 is x = 23.9

The distance from the check point when Odalis catch up Jaquan is 1.2 kilometers.

Relative speed is the net speed difference when objects move in the same direction and sum of individual speeds when objects move in opposite direction.

Given Jaquan speed is 9km/hr which is 0.15km/minute and Odalis has a speed of 12km/hr which is 0.2km/minute.

∴ The relative speed difference between Jaquan and Odalis is

= (0.2 - 0.15) km/hr.

= 0.05 km/hr.

Given Odalis reached the check post after 2 minutes in this time Jaquan have covered (2×0.15) kilometers.

= 0.30 kilometers.

Now to catch up Jaquan, Odalis will need (0.30/0.05) minutes which is

= 6 minutes.

∴ The distance from the check post Odalis travelled to catch up with Jaquan is (0.2×6) kilometers.

= 1.2 kilometers.

Answer:

y=-4x+0

Step-by-step explanation:

Slope form is y=mx+b

m is the slope, and b is the y intercept. If the line must pass through (0,0) then the y intercept would be zero.

This give you y=mx+0

Now to find the slope you need a perpendicular line to the previous line. This would mean you have to swap 1/4 which is the previous lines slope.

1/4 is a positive so make it a negative, -1/4

Now flip -1/4 to make is -4/1 which also equals -4

Now with the slope -4 and y-intercept 0, you know you equation

y=-4x+0

Answer:

1. (-1.5,0), -3/2, or -1(1/2)

2.(-16,0)

Step-by-step explanation:

1. explanation:

the 2 and the -5 are 8 spaces apart (-5,-4,-3,-2,-1,0,1,2). the exact halfway point of them is -1.5. the exact halfway point between 5 and -5 is 0. thus led me to (-1.5,0.) I then graphed it on desmos to see if it was halfway, which it is. (refer to the image)

2. explanation:

the distance between -6 and 4 is 10, so -16 would be the first half of the endpoint location. Then the distance between 4 and 8 is 4, so 4-4 is 0. the start point of 2 is (-16,0)

[tex]\frac{5}{42}[/tex]

Step-by-step explanation:

It makes a difference if the marbles are place bag into the bag after selecting.  Since this is not stated, I am assuming that once a marble is selected, it is not placed back in the bag.

[tex]\frac{5}{9}[/tex] x [tex]\frac{4}{8}[/tex] x [tex]\frac{3}{7}[/tex] = [tex]\frac{60}{504}[/tex]  This simplified would be [tex]\frac{5}{42}[/tex]  The 5 represent the number of blue marbles available our of 9 total marbles.  Next, we only have 4 blue marbles available out of a total of now 8 marbles and lastly, for the third draw we only have 3 blue marbles available and only 7 total marbles are left.

If the marbles are replaces that changes the problem and the answer would be [tex]\frac{5}{9}[/tex] x [tex]\frac{5}{9}[/tex] x [tex]\frac{5}{9}[/tex] = [tex]\frac{121}{729}[/tex]

The possible values of x are 3 and 7

Given the rational expression below;

√60-8x = x - 9

Square both sides to have:

(60-8x)² = (x-9)²

60-8x = x²-18x+81

Equate to zero to have;

x²-18x+81 - 60 + 8x = 0

x² - 10x + 21 = 0

x² -3x-7x +21 = 0

x(x-3)-7(x-3) = 0

x = 3 and 7

Hence the possible values of x are 3 and 7

The value of the function f(3) is 1

The graph represents the given parameter

The value of f(3) implies that we calculate the value of the function when x = 3

From the graph, we have

f(x) = 1, when x = 3

This means that

f(3) = 1

The above is calculated by substituting 3 for x in the equation f(x) = 1

Hence,  the value of f(3) is 1
