Answer: 336 different ways

Step-by-step explanation:

Ok, we have a total of 8 horses, and we have 3 places.

First, second, third.

The total number of combinations will be equal to the product of the number of possible options that we have in each place.

For the first place, we could have any of the 8 horses, so there are 8 possible options.

For the second place, we will have 7 horses (because one is already in the first place) then here we have 7 options.

For the third place, we will have 6 horses (because one is in the first place and another is in second place) then here we have 6 options.

The total number of different ways in which the horses can finish is:

C = 8*7*6 = 336 different ways

Answer:

c. X= {0,1,3}

Step-by-step explanation:

We have these possible outcomes:

None assigned to their favorite cities.

One assigned to their favorite city(The other two are assigned to the other's favorite city).

All are assigned to their favorite city.

Why is two not possible?

If two peooke are assigned to their favorite city, the third person necessary has to be assigned to their favorite city, as it will be the only option remaining.

So the correct answer is given by option c.

x=4 y=1

Step-by-step explanation:

We'll use the exponent rule that a^(b+c) = a^b*a^c

to break up 17^16 into 17^(14+2) = 17^14*17^2

That allows us to factor like so

17^16+17^14

17^14*17^2+17^14*1

17^14(17^2 + 1)

Computing 17^14 is a lot more difficult compared to computing 17^2 + 1, assuming you only could use paper and pencil.

Note that 17^2 = 17*17 = 289, so 17^2 + 1 = 289+1 = 290

Because 290 ends in a 0, this means that 5 is a factor

290 = 5*58

This makes 5 to be a factor of the original expression.

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

So overall,

17^16+17^14 = 17^14(17^2 + 1) = 17^14*290 = 17^14*5*58 = 5*17^14*58

The stuff "17^14*58" doesn't matter. All we care about is that factor of 5.

Since 5 is a factor, this means that 17^16+17^14 is a multiple of 5, or 17^16+17^14 is divisible by 5.

Phrased another way, 17^16+17^14 all divided over 5 leads to some integer. In this case, the integer would be the result of 17^14*58.

b)31

Step-by-step explanation:

a) 1 half hour = 90 min

90÷30=3

9.30÷3=3.10

b)5 hrs -> 300 min

300÷30=10

10x3.10=31

Answer:

10(2x-1)

Step-by-step explanation:

Since the GCF (greatest common factor) of 20 and 10 is 10 We factor out the 10.

=> 10(2x-1)

Answer:

area of the square is 16 inches

area of the square = perimeter of the square

Step-by-step explanation:

each side of the square is 4" so

A = 4 x 4 or 16 sq in

Answer:

a) 4800 bacteria

b) [tex]y(t) = 300(4)^t[/tex]

c) 754 bacteria

Step-by-step explanation:

A bacteria culture starts with 300 bacteria and doubles in size every half hour.

This means that the number of bacteria after t periods of half hour is given by:

[tex]y(t) = 300*(2)^{t}[/tex]

(a) How many bacteria are there after 2 hours?

2 hours is 2*60/30 = 4 periods of 2 hours, so this is y(4).

[tex]y(4) = 300*(2)^{4} = 300*16 = 4800[/tex]

(b) How many bacteria are there after t hours?

It doubles every half hour, so each hour, it is multiplied by 4. Then

[tex]y(t) = 300(4)^t[/tex]

(c) How many bacteria are there after 40 minutes?

40 minutes is 40/30 = 1.33 periods of half hour. So this is y(1.33).

[tex]y(1.33) = 300*(2)^{1.33} = 754[/tex]

Answer:
