30% percent is what they marked up
Answer:
y = a(1 + r) ^v
y = 6200( 1 + 0.05)^v
y = 6200(1.05)^v
Step-by-step explanation:
Fred purchased a piece of artwork for 6200, and it is expected to increase in value by 5% per year. Write a function y to represent the value of the piece of artwork after v years.
The function we can used to represent the above question is given as Exponential Growth function.
Where the number of years = v
The value of the artwork = y
y = a(1 + r) ^v
Where
a = Initial value of the artwork = 6200
r = Growth rate = 5% = 0.05
v = number of years
Therefore, the function y to represent the value of the piece of artwork after v years is written as:
y = 6200( 1 + 0.05)^v
y = 6200(1.05)^v
Answer:400
Step-by-step explanation:
10%= 200
x2=400
Answer: c) -0.3
<u>Step-by-step explanation:</u>
Consider the left point as (x₁, y₁) and the right point as (x₂, y₂)
then (x₁, y₁) = (-6, -1) & (x₂, y₂) = (5, 1)
x₂ - x₁ = 5 - (-6) = 11
y₂ - y₁ = 1 - (-1) = 2
ratio of a:b = a/(a+b)
1 : 2 = 1/(1 + 2) = 1/3
x-coordinate: x₁ + ratio(x₂ - x₁) = -6 + (1/3) (11) = -7/3
y-coordinate: y₁ + ratio(y₂ - y₁) = -1 + (1/3) (2) = -1/3
