How many batting lineups are there for nine players of a baseball team if the center fielder must bat fourth, the second baseman must bat third and the pitcher last?

Answers

The number of possible batting lineups is 720

Explanation

Total number of players in the team = 9

The center fielder must bat fourth, the second baseman must bat third and the pitcher last. That means, 3 slots in the batting line-up are already assigned to 3 players.

So, the remaining (9 - 3) = 6 players will be assigned to remaining 6 slots.

Thus, the possible number of ways so that 6 players can be assigned to 6 slots will be: $6! = 6*5*4*3*2*1=720$

The distance an object falls when dropped from a tower varies directly as the square of the time it falls. If the object falls 144 feet in 3 seconds, how far will it fall in 17 seconds?

Answers

Direct variation:
$y=kx^2$
y - the distance, x - the time

The object falls 144 feet in 3 seconds.
$144=k * 3^2 \n144=9k \nk=(144)/(9) \nk=16 \n \Downarrow \n y=16x^2$

The object falls y feet in 17 seconds.
$y=16 * 17^2 \ny=16 * 289 \ny=4624$

In 17 seconds the object will fall 4624 feet.

The Eagles basketball team scored 12 more than 2 times as many points in the last game of the season than in the first game. Which expressions can be used to find the number of points the Eagles scored in the last game? Select all the expressions that apply.

Answers

Answer:

A. 12+2p

G. p+p+12

Step-by-step explanation:

The Eagles basketball team scored 12 more than 2 times as many points in the last game of the season than in the first game

Number of points scored in the last game of the season = 2p + 12

A. 12+2p

Equivalent

B. 2+p+12

= P + 14

Not equivalent

C. 2+12p

Not equivalent

D. p(2+12)

= 2p + 12p

Not equivalent

E. p+2+12

= P + 14

Not equivalent

F. 12p+2p

Not equivalent

G. p+p+12

= 2p + 12

x2 – 8x – 20 A) (x – 5)(x + 4)

x2 + 8x – 20 B) (x – 10)(x + 2)

x2 – x – 20 C) Prime

x2 – 9x – 20 D) (x – 2)(x + 10)

Answers

Answer:

Step-by-step explanation:

The given equation is:

$x^(2)-8x-20$

Simplifying the above equation, we get

$x^(2)-10x+2x-20$

$x(x-10)+2(x-10)$

$(x+2)(x-10)$

therefore, the equation $x^(2)-8x-20$ matches with (B) $(x+2)(x-10)$ .

The given equation is :

$x^(2)+8x-20$

Simplifying the above equation, we get

$x^(2)+10x-2x-20$

$x(x+10)-2(x+10)$

$(x-2)(x+10)$

therefore, the equation $x^(2)+8x-20$ matches with (D) $(x-2)(x+10)$

The given equation is:

$x^(2)-x-20$

Simplifying the above equation, we get

$x^(2)-5x+4x-20$

$x(x-5)+4(x-5)$

$(x+4)(x-5)$

therefore, the equation $x^(2)-x-20$ matches with (A) $(x+4)(x-5)$ .

The given equation is:

$x^(2)-9x-20$

This equation ca't be firther simplified or factorised, thus the equation $x^(2)-9x-20$ matches with (C) Prime.

the correct matches for the polynomials are:

A) (x – 5)(x + 4) matches with x^2 – x – 20.

B) (x – 10)(x + 2) matches with x^2 + 8x – 20.

C) Prime does not match any of the given terms.

D) (x – 2)(x + 10) matches with x^2 – 9x – 20.

How did we arrive at these assertions?

Let's factor each trinomial and match them with their factored forms:

x² – 8x – 20:

To factor this trinomial, we need to find two numbers that multiply to give -20 and add up to -8. The numbers that satisfy these conditions are -10 and 2. Therefore, the factored form is (x – 10)(x + 2). Match: A.

x² + 8x – 20:

For this trinomial, we once again look for two numbers that multiply to give -20 and add up to 8. The numbers are -2 and 10. Hence, the factored form is (x – 2)(x + 10). Match: D.

x² – x – 20:

Here, we seek two numbers that multiply to give -20 and add up to -1. The numbers -5 and 4 satisfy these conditions. Thus, the factored form is (x – 5)(x + 4). Match: A.

x² – 9x – 20:

Similar to the previous trinomials, we search for two numbers that multiply to give -20 and add up to -9. The numbers are -10 and 1. So, the factored form is (x – 10)(x + 1). Match: B.

Matching the terms with their factored forms:

A) (x – 5)(x + 4) matches with x² – x – 20.

B) (x – 10)(x + 2) matches with x² + 8x – 20.

C) Prime does not match any of the given terms.

D) (x – 2)(x + 10) matches with x² – 9x – 20.

Therefore, the correct matches are:

A) (x – 5)(x + 4) matches with x² – x – 20.

B) (x – 10)(x + 2) matches with x² + 8x – 20.

C) Prime does not match any of the given terms.

D) (x – 2)(x + 10) matches with x² – 9x – 20.
