A restaurant offers a catering service which costs $25.00 per person with a $119.50 service charge. For parties of 50 or more pe
Molodets [167]

Answer:

T1(n) = 25n +119.50  where n belongs to 1 \leq n.

T2(n) = 20n + 59 where n belongs to 50\leq  n.

Step-by-step explanation:

We are given two situations first is for normal days and the other is for days when 50 or more people are going to this restaurant for the party.

Let the number of person going for this restaurant be "n"

For normal day, we are given

catering service = $25 per person

service charge = $119.50  

Let the total cost of the restaurant be T

Cost for this case will be T1  

T1(n) = 25n +119.50  where n belongs to 1 \leq n

similarly for the case when 50 or more than that goes to this restaurant for party.

cost after discount

Catering service = $20.00 per person

service charge = $59.00

now the cost of this case will be T2

T2(n) = 20n + 59 where n belongs to 50\leq  n.

Therefore the two piecewise linear functions represents the total cost of the restaurant for serving n people.

Los puntos (1,-2);(-8,4 y (5,2) son los vertices de un triangulo rectángulo su perimetro es aproximadamente
Alenkasestr [34]

Answer:

El perímetro del triángulo rectángulo es aproximadamente 29.627.

Step-by-step explanation:

Las coordendas de los vértices del triángulo rectángulo son A(x,y) = (1,-2), B(x,y) = (-8,4) y C(x,y) = (5,2). En primer lugar, determinamos las longitudes de los segmentos AB, BC y AC por el Teorema de Pitágoras:

AB = \sqrt{(-8-1)^{2}+[4-(-2)]^{2}}

AB \approx 10.817

BC = \sqrt{[5-(-8)]^{2}+(2-4)^{2}}

BC \approx 13.153

AC =\sqrt{(5-1)^{2}+[2-(-2)]^{2}}

AC \approx 5.657

El perímetro del triángulo (p) es la suma de todos estos segmentos:

p = AB + BC + AC

p \approx 29.627

El perímetro del triángulo rectángulo es aproximadamente 29.627.
