Answer:
Correct answer: C (6.5 , - 8)
Step-by-step explanation:
Given points A(-1,-2) and B(9, -10)
The formula by which we calculate the coordinates of a point, let be C, that divides the line segment in the given ratio is.
Xc = (Xa + λ · Xb) / (1 + λ) and Yc = (Ya + λ · Yb) / (1 + λ)
Where λ is the coefficient which depends on the direction of the ratio in this case is:
λ = 3 : 1 = 3
Xc = (-1 + 3 · 9) / (1 + 3) = (-1 + 27)/ 4 = 26 / 4 = 6.5
Xc = 6.5
Yc = (-2 + 3 · (-10) / (1 + 3) = (-2 - 30)/ 4 = -32 / 4 = - 8
Yc = - 8
God is with you!!!
<em>To find the answer, just do the inverse. That is, do 4×2. 4×2=8 and 8÷4=2. So A=8.</em>
Answer:
Product 3
Step-by-step explanation:
You can easily find it out based on the last column (Year 3)... where product 3 has the highest market value.
This is very logical due to exponential nature of the price evolution function... it might start lower than most of the other products, but it will grow at a much faster rate... so much that in second year, it's already tie for the most market value.
In year 3, the difference is obvious and it would be even bigger in the following years.
