Which expression has a value that is less than the base of that experience?

Rom4ik [11]

Answer:

(B) $(\frac{5}{6})^{2}$

Step-by-step explanation:

(A) The given expression is: $2^{3}$

= $8$

The value of this expression is 8 which is greater than the base of the expression that is 2.

(B) The given expression is: $(\frac{5}{6})^{2}$

= $\frac{25}{36}$

= $0.09$

The value of this expression is 0.09 which is smaller than the base of the given expression that is 0.83.

(C) The given expression is: $3^{2}$

= $9$

The value of this expression is 9 which is greater than the base of the given expression that is 3.

(D) The given expression is: $4^{4}$

= $256$

The value of this expression is 256 which is greater than the base of the given expression that is 4.

Hence, Option B is correct.

A football stadium is capable of seating a maximum of m fans. For each game, the

klasskru [66]

Answer:

The revenue depends on the number of people n that purchases tickets, knowing that each ticket costs $30.00, the total revenue will be:

f(n) = $30.00*n

Now, we also know that the stadium is capable of seating a maximum of m fans, so the maximum possible value for n is m.

Now, for the function f(n), we have that:

The domain is the set of the possible values of n

The range is the set of the possible values of f(n).

We want to find the domain.

First, the minimum possible value of n is 0, the case where nobody purchases a ticket.

The maximum possible value of n is m, this is the case where the stadium is full.

Then the domain will be:

D= {n,m ∈ Z, 0 ≤ n ≤ m}

Where we imposed that n must be an integer number because n represents a whole quantity.
