Arestaurant charges $100 to rent its banquet room for an event. it also charges $15 to serve dinner to each guest. write an equation for the total cost of the banquet room in terms of the number of guests. deine your variables. what is the total cost of the banquet room for 20 guests?

a) 100 + 15x

b) $400

Step-by-step explanation:

To find out the equation for the first part, we know that the cost of the banquet room for an event is $100. To add, for each guest (x), we add another $15, which means you have to multiply the price of each guest with the number of guests (x)

To find out part (b), you have to substitute x as 20 in the equation and you shall arrive at the answer of $400

18.42 m

Step-by-step explanation:

At that point, the ball will be static, with final velocity of 0.

The initial velocity is 19.

The acceleration due to gravity is -9.8 m/s^2.

We now have to use an equation of kinematics shown below:

Where

 is the final velocity

is the initial velocity

a is -9.8

s is the distance we are looking for

Lets substitute and find the
