Since the line goes through (0, 0), it can be described by
y = kx
You are given the point (12, 72), so you know
72 = 12k
6 = k . . . . . . . divide by 12
Then the equation of the line is ...
y = 6x
She will have $57 back because the ticket are buy one get one free and she has 7 friends so for 3 tickets that u buy 6 of your friend get to go and then thei is still one more friend so you have to buy one more ticket so 10.75*3=32.25
and 32.25+10.75=43 and 100-43=57
Answer:
El mayor lado del rectángulo es de 10 cm
Explicación paso a paso:
Perímetro de un rectángulo: es el doble de la suma de sus lados
P = 2 (a+b)
a: es el ancho del rectángulo
b: es el largo del rectángulo
Uno de los lados es 6cm mas que el otro lado
b= a + 6 cm
Sustituimos en la ecuación de perímetro:
28cm /2 = a+a+6cm
14cm = 2a +6 cm
14cm-6cm = 2a
a = 4 cm
b = 10cm
El mayor lado del rectángulo es de 10 cm

Answer:
Step-by-step explanation:
Root:
n≈0.00833333 m + 0.666667
Root for the variable n:
n≈-0.0833333 (-0.1 m - 8)
Derivative:
d/dm(0.1 m + 8 - 12 n) = 0.1
Indefinite integral:
integral(8 + 0.1 m - 12 n) dm = 0.05 m^2 - 12 m n + 8 m + constant
Definite integral over a disk of radius R:
integral integral_(m^2 + n^2<R^2)(0.1 m - 12 n + 8) dm dn = 8 π R^2 + 0
Definite integral over a square of edge length 2 L:
integral_(-L)^L integral_(-L)^L (8 + 0.1 m - 12 n) dn dm = 32 L^2 + 0
