Answer:120

Step-by-step explanation:

Answer:

120

Step-by-step explanation:

Given information:

• 4x³ + 4x

• x = 3

To evaluate the expression further, plug in the given variable and simplify:

4x³ + 4x          Replace x with 3.

4(3)³ + 4(3)      PEMDAS - put 3 to the 3rd power.

4(27) + 4(3)     Use the distributive property to get rid of the parentheses.

108 + 12          Add the two values.

120

The simplification of 4x³ + 4x when x = 3 is 120.

Answer:  [tex]\frac{37}{1,101,716,330}\\\\[/tex]

This is the same as writing 37/1101716330

======================================================

Explanation:

Let's say the nine winning numbers are: 1,2,3,4,5,6,7,8,9

Let's further say that if we matched everything from 1 to 8, then we'll win second prize. That ninth value can be anything but 9. So we could have something like one of these examples

As you can see, there are 46-9 = 37 different choices we can have for that last slot. In other words, there are 37 items in the set {10,11,12,...,45,46} we can pick for that last ninth slot. Note that 46-10+1 = 37. This value will form the numerator of the answer.

------------------------------------------

Now to calculate how many ways there are to select the nine values regardless if we win or lose.

Since order doesn't matter, we use the nCr combination formula.

[tex]_{n} C _{r} = \frac{n!}{r!*(n-r)!}\\\\_{46} C _{9} = \frac{46!}{9!*(46-9)!}\\\\_{46} C _{9} = \frac{46!}{9!*37!}\\\\_{46} C _{9} = \frac{46*45*44*43*42*41*40*39*38*37!}{9!*37!}\\\\[/tex]

[tex]_{46} C _{9} = \frac{46*45*44*43*42*41*40*39*38}{9!} \ \text{ ... the ``37!'' terms cancel}\\\\_{46} C _{9} = \frac{46*45*44*43*42*41*40*39*38}{9*8*7*6*5*4*3*2*1}\\\\_{46} C _{9} = \frac{399,790,821,830,400}{362,880}\\\\_{46} C _{9} = 1,101,716,330\\\\[/tex]

There are slightly over 1 billion ways to select the nine values.

This large value is the denominator of our answer which is [tex]\frac{37}{1,101,716,330}\\\\[/tex]

The 37 up top represents the number of ways to win the second prize we're after, while the massive number in the denominator represents how many ways there are to play the game.

------------------------------------------

Notice that in the jump from step 4 to step 5, shown in the section above, we had the "37!" terms cancel out. What this means is that the prime number 37 is nowhere to be found anywhere in the factorization of 1,101,716,330

Why is this important? Because it tells us that the fraction [tex]\frac{37}{1,101,716,330}\\\\[/tex] cannot be reduced.

Side note: That fraction converts to the decimal form 0.00000003358397 approximately and that converts to the percentage form 0.000003358397%; both of which are very very small numbers. We can see that the odds are definitely stacked against the player.

Answer:

The length is 83 and the width is 57

Step-by-step explanation:

The width is 26 meters less than the length, so we'll represent the width with: L-26. Since there are 2 widths to account for, we'll multiply this by 2.

Equation looks like this so far: 2(L-26)

Then, add the 2 lengths and set the expression equal to 280.

Equation: 2(L-26)+2L=280

Distribute the 2 in the first term, making the equation look like:

2L-52+2L=280

Add the 52 to both sides of the equation

4L=332

Divide by 4 on both sides

L=332/4=83

L=83

Width is 26 meters less, so 83-26=57

W=57

The second attachment tells you the foci are located at (0, ±(a²+b²)), where a² and b² are the denominators in the above equation. That is the foci are ...

  (0, ±√(4+5)) = (0, ±3) . . . . as shown in the graph

This confirms the equation denominators are rightly 5 and 4, with 5 being the denominator of y².

If Jasmine books 36 appointments each day, 6 appointments will be canceled.

Number of appointments booked each day = 36 appointments

Since four out of every 24 appointments are canceled. This means the fraction of appointments that are canceled will be:

= 4/24 = 1/6

Now, since three are 36 appointments each day, the number of appointments that are canceled will be:

= 1/6 × 36

= 6 appointments

In conclusion, 6 appointments will be canceled each day.

Answer:

Step-by-step explanation:

This is basically the same thing as the last question.

The domain goes from - 8 to 5. The 5 has an open circle for it's endpoint < does not include the end point

the range is a little tricky. It goes from - 6  to 9. The -6 is has a circle (because it is not included in the answer). I'm not sure how you show that on a graph.

I think the best answer is this: if either the domain or range is separated by < then you must change the one that uses ≤ into < so the endpoints of the domain are in agreement. You cannot have the domain using < when the range uses ≤. They both must be the same. I think the best choice is<

Answer:

A dryer costs $450.

A washer costs $509.

Step-by-step explanation:

Let:

"washer" = x

"dryer" = y

Set the equations:

x + y = 959

x = y + 59

First, plug in y + 59 for x in the first equation for x:

x + y = 959

(y + 59) + y = 959

Simplify, combine like terms:

y + y + 59 = 959

2y + 59 = 959

Next, isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis, Exponents (& Roots), Multiplications, Divisions, Additions, Subtractions.

First, subtract 59 from both sides of the equation:

2y + 59 (-59) = 959 (-59)

2y = 959 - 59

2y = 900

Next, divide 2 from both sides of the equation:

(2y)/2 = (900)/2

y = 900/2

y = 450

Next, plug in 450 for y in one of the equations:

x = y + 59

x = (450) + 59

x = 509

Check:

x + y = 959

450 + 509 = 959

959 = 959 (True).

~

Answer:

$450

Step-by-step explanation:

1. First, let's make a system of equations:

2. (Solving)

Solve y + 59 = x for y:

Substitute x - 59 for y in x + y = 959

Substitute 509 for x in y = x - 59

Therefore, the dryer costs $450. (The washer costs $509).

Answer:

A train leaves the station at 9:00 pm traveling east at 36 miles per hour. A second train leaves the station at 10:00 pm traveling west at 42 miles per hour. At what time will both trains have traveled the same distance?

------

Let t equal the time that passed right after 10 PM.

42t = 36 (t + 1)  

42t = 36t +36  

6t = 36  

t = 6 hours

Answer: 4 AM ✅

Step-by-step explanation:

The car traveled 200 m distance with a speed of 50 m / hr in 4 hr.

Given that,
To determine the total distance in meters of a car that travels due west at 50 m/hr west between 12:00 and 4:00 pm.

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

Distance is defined as the object traveling at a particular speed in time from one point to another.

Here, the car travels due west at 50 m/hr west between 12:00 and 4:00 pm
Time = 12:00 - 4:00 = 4 hours
Speed = 50 m / hr
Distance = 50 * 4
             = 200 m

Thus, the car traveled 200 m distance with a speed of 50 m / hr in 4 hr.
