At a race track you have the opportunity to buy a ticket that requires you to pick the first and second place horses in the firs

rewona [7]

Answer:

4032 different tickets are possible.

Step-by-step explanation:

Given : At a race track you have the opportunity to buy a ticket that requires you to pick the first and second place horses in the first two races. If the first race runs 9 horses and the second runs 8.

To find : How many different tickets are possible ?

Solution :

In the first race there are 9 ways to pick the winner for first and second place.

Number of ways for first place - $^9C_1=9$

Number of ways for second place - $^8C_1=8$

In the second race there are 8 ways to pick the winner for first and second place.

Number of ways for first place - $^8C_1=8$

Number of ways for second place - $^7C_1=7$

Total number of different tickets are possible is

$n=9\times 8\times 8\times 7$

$n=4032$

Therefore, 4032 different tickets are possible.

2^2x+2 *5^x-1=8^x*5^2x

Liula [17]

Answer:

The solution will be "x = 2 and x = -1".

Step-by-step explanation:

The given equation is:

⇒ $2^{2x+2}\times 5^{x-1}=8^x\times 5^{2x}$

On solving " $8^x$ ", we get

⇒ $2^{2x+2}\times 5^{x-1}=(2^3)^x\times 5^{2x}$

As we know, if the base are same then their powers will be added together.

⇒ $2x+2=3x$ ...(equation 1)

⇒ $x-1=2x$ ...(equation 2)

From equation 1, we get

⇒ $2=3x-2x$

⇒ $2=x \ i.e., x =2$

From equation 2, we get

⇒ $-1=2x-x$

⇒ $-1=x \ i.e., x=-1$

So that the correct answer will be "x = 2" and "x = -1".
