6 0

Answer:

R$49.02

R$49.09

Step-by-step explanation:

Por não pagar a conta em dia, o valor de 2% de juros foi adicionado, o novo valor base passa a ser:

V = 1.02*48\\V=R\$48.96

O valor a ser pago n dias após o dia 13 de abril é dado por:

P=48.96*(1+\frac{0.033}{100} )^n

No dia 17 de abril, n =4 e o valor a ser pago é:

P=48.96*(1+\frac{0.033}{100} )^4\\P=R\$49.02

Caso n =8, o valor a ser pago seria:

P=48.96*(1+\frac{0.033}{100} )^8\\P=R\$49.09

PLEASE HELP!!! WORTH 20 POINTS!
Mkey [24]

Answer:

a. 1 1/2 (or 3/2)

b. 2/3

c. 1

d. 1

Step-by-step explanation:

Part A: (1,1) (7,5)

To determine the slope, you will use the equation m=(y2-y1)/(x2-x1). Keep in mind that it doesn't matter what point you use for (x1, y1) or (x2, y2).

Let's plug in the numbers for part a:

m=(7-1)/(5-1)

Let's then solve the problems inside the parentheses:

m=6/4

And finally, we simplify:

m=3/2 (or 1 1/2 depending on what your teacher wants for an answer)

For these others, I will just go through the steps and not explain them, if you need help or don't understand something I'm doing, either look back at what I did for part a or comment on this answer.

Part B: (1,1) (5,7)

m=(5-1)/(7-1)

m=(4/6)

m=2/3

Part C: (2,5) (-1,2)

m=(-1-2)/(2-5)

m=(-3/-3)

m=1

Part D: (2,5) (-7,-4)

m=(-7-2)/(-4-5)

m=(-9/-9)

m=1
