Evaluate the given expression. Subscript 5 Baseline P Subscript 2 a. 40 c. 25 b. 32 d. 20

Leto [7]

Answer:

d. 20

Step-by-step explanation:

The given question implies 5 permutation 2, i.e $_{5}$ $P_{2}$ .

But,

$_{n}$ $P_{r}$ = $\frac{n!}{(n - r)!}$

So that for $_{5}$ $P_{2}$ , n = 5 and r = 2.

$_{5}$ $P_{2}$ = $\frac{5!}{(5 - 2)!}$

= $\frac{5!}{3!}$

= $\frac{5*4*3*2!}{3*2!}$

Cancel out 3 and 2 with respect to the numerator and denominator.

$_{5}$ $P_{2}$ = 5 * 4

= 20

Therefore,

$_{5}$ $P_{2}$ = 20

So that the correct option is D.

$f(x) = 9x - 7$

$f( - 1) = 9( - 1) - 7$

$f( - 1) = - 9 - 7$

$f( - 1) = - 16$

$\huge \boxed{ \green{ANSWER}}$

$\underline{v = 13 \: 520 \: {m}^{3} }$

$\huge \boxed{ \red{SOLUTION}}$

$v = lwh \\ = (52m) \: (13m) \: (20m) \\ \implies \underline{v = \: 13 \: 520 \: {m}^{3} }$
