Stella [2.4K]

Answer:

8 different combinations are possible.

Step-by-step explanation:

Here, we have 2 different combinations for each time.

And the player comes out to bat 3 times.

So, total number of combinations are:

2^{3} i.e. a total of 8 number of times.

Let a hit is termed as 'H' and an out is termed as 'O'.

Total combinations are:

{HHH, HHO, HOH, HOO, OHH, OHO, OOH, OOO}

Kindly have a look at the tree diagram attached in the answer area.

In starting, there are 2 combinations possible, i.e. 'O' and 'H'.

After 'O' , 2 possible i.e. 'O' and 'H'.

After 'H' , 2 possible i.e. 'O' and 'H'.

and so on....

Given the factors, name the roots.<br> 3. f(x) = -3(2x – 5)(x + 2)
tekilochka [14]

Answer:

x = 5/2

or

x = -2

Step-by-step explanation:

recall that the roots of a function f(x) are basically the values of x that will make f(x) = 0,

we find these values of x by making f(x) = 0 and then solving the equation for x,

in our case,

f(x) = -3(2x – 5)(x + 2)

to find roots,

f(x) = 0

-3(2x – 5)(x + 2) = 0

Equating each factor = 0, the equation can be broken down into:

-3 = 0 (obviously not valid, hence we can ignore this)

or

(2x – 5) = 0     add 5 to both sides

2x = 5              divide both sides by 2

x = 5/2   ( Answer)

or

(x + 2) = 0      subtract 2 from both sides

x = -2 (Answer)
