Answer:

<em>C = 13π ≈ 40.82 units </em>

Step-by-step explanation:

C = 2 r π = d π

AB = $\sqrt{(-8-4)^2 +(4+1)^2}$ = 13 units

<em>C = 13π ≈ 40.82 units</em> ( π ≈ 3.14 )

If f(x) = 3x2 + 1 and g(x) = 1 - x, what is the value of (f - g)(2)

klio [65]

Answer:

Step-by-step explanation:

(f - g)(x) = f(x) - g(x)

f(x) - g(x)

= 3x² + 1 - (1 - x)

= 3x² + 1 - 1 + x

= 3x² + x , thus

(f - g)(2)

= 3(2)² + 2 = 3(4) + 2 = 12 + 2 = 14

A stadium has 20,000 reserved seats and 25,000 general admission seats. If reserved seats are $17.50 and general admission seats

Radda [10]

Answer:

The answer is D. $618,750.

Step-by-step explanation:

20,000 x 17.50 = 350,000.

25,000 x 10.75 = 268,750.

350,000 + 268,750 = 618,750.

*HELP PLEASE*

aksik [14]

If two events are disjoint (i.e. mutually exclusive) they cannot both occur and so we can determine probabilties by simple addition:

$P(AorB)=P(A)+P(B)$
$P(AorB)=\frac{40}{61}+\frac{2}{61}$
$P(AorB)=\frac{42}{61}$
$P(AorB)\approx 68.8\%$

A more complete answer would use a joint probability table but that's difficult to type out/format correctly here.
