Mel bought pizza and soda for her End of Summer party. If she spent $12.57 on the sodas and $10.95 for each pizza, how many pizz
sammy [17]

The equation that models the situation is: 89.22 = $10.95p  +  $12.57.

The cost of one pizza is $10.95. The cost of 2 pizzas would be equivalent to the multiplication of $10.95 by 2. Since we are not provided with the information on the total amount of pizza she bought, the total number of pizza bought would be represented with p.

Thus the total cost of p boxes of pizza = $10.95 x p = $10.95p

The total amount spent on sodas is $12.57.

The total amount spent is $89.22.

The equation that models the situation is: 89.22 = $10.95p  +  $12.57.

Identify the period for the trigonometric function: f (t) = 3cot(πt).
jekas [21]

Answer:

Correct choice is A

Step-by-step explanation:

The period of the function f(t)=a\cot (bt+c) is always

T=\dfrac{\pi}{b}

(coefficients a and c do not influence).

In your case, for the function f(t)=3\cot (\pi t) the period is \dfrac{\pi}{\pi}=1.
