5 days are possible Schedule are there to play hockey on Wednesday or Monday or both.

Let's solve the problem with the help of the Set theory.

Let Set A be the given days Bob only plays hockey.

Set A = { Tuesday, Wednesday, Friday}

Let Set B be the given days Ron only plays hockey.

Set B = { Thrusday, Sunday}

So, (Set A \cap Set B ) = 0 (Null Set) which denotes days in which both of them play together.

(Set A \cup Set B ) = { Tuesday, Wednesday, Thursday, Friday, Sunday} > which denotes days in each week at least one of them plays hockey.

Set theory is the branch of mathematical logic that studies sets, which can be informally described as sets of objects. All sorts of objects can be grouped into sets, but set theory as a branch of mathematics deals mainly with mathematics as a whole.

You go to the doctor and he gives you 13 milligrams of radioactive dye. After 20 minutes, 4 milligrams of dye remain in your sys

Rudik [331]

Answer:

7 minutes

Step-by-step explanation:

At first, I thought this was a hal-life problem, but there was too much left unknown to fill in the half-life equation. So I went with exponential.

The general form of an exponential equation is

$y=a(b)^x$

where a is the initial amount given, b is the growth/decay rate (ours is decay since the amount of dye is decreasing), y is the amount of dye in your system after x minutes.

We have to come up with a model for this situation before we can answer the question. The equation has 2 unknowns: a and b. We need to solve for those. In order to do that, we need 2 coordinate points to sub in for x and y. The first coordinate point in (time, amt dye) is (0, 13). This means that immediately upon arriving at the doctor, after 0 time has gone by, you were given 13 mg of dye.

The second coordinate point is (20, 4). This means that after 20 minutes, you had 4 mg of dye in your system.

Use the first coordinate point to solve for a:

$13=a(b)^0$

Since anything in the world raised to a power of 0 is 1, then

a = 13.

Now we will use the second coordinate point along with that value of a to solve for b:

$4=13(b)^{20}$

Begin by dividing both sides by 13 to get

$\frac{4}{13}=b^{20}$

Now you have to undo that power of 20 by taking the 20th root of both sides:

$\sqrt[20]{\frac{4}{13} }=\sqrt[20]{b^{20}}$

The right side simplifies down to just b, and the 20th root of the left side is .9427701685

Therefore, b = .9427701685

The model, then, is:

$y=13(.9427701685)^x$

We need to use that model now to solve for x, the number of minutes it will take for y = 2 mg of dye to remain in your system. That looks like this:

$2=13(.9427701685)^x$

Begin by dividing both sides by 13 to get

$\frac{2}{13}=.9427701685^x$

We need to get that x out of the position in which it is currently sitting, which is as the exponent. Do that by taking the natural log of both sides. That allows us to bring the exponent down out front:

$ln(\frac{2}{13})=x*ln(.9427701685)$

To solve for x, divide both sides by ln(.9427701685). I have entered the values of the natural logs in the next step:

$\frac{-.4054651081}{-.0589327498}=x$

Divide to get

x = 6.9 or 7 minutes

Ramesh marks 48,56,98 what is average

gizmo_the_mogwai [7]

Answer:

Ramesh scores about 67.3

Step-by-step explanation:

To find average we need add all the numbers and divide by the number of numbers so:

48+56+98=202

202/3= 67.333

67.33%

Find the product. (y2 - 3)(y4 - 6y2 + 9)

asambeis [7]

(y² - 3)(y⁴ - 6y² + 9)

y²(y⁴ - 6y² + 9) - 3(y⁴ - 6y² + 9)

y².y⁴ - y².6y² + y².9 -3.y⁴ - 3.(-6y²) -3.( 9)

y⁶ - 6y⁴ + 9y² - 3y⁴ + 18y² -27

y⁶ - 6y⁴- 3y⁴ + 9y² + 18y² - 27

y⁶ - 9y⁴ + 27y² - 27

I hope this helps.
