Answer:
Step-by-step explanation:
given,
initial price of buzz stock = $ 20 per share
after 20 days
stock price = $30 per share
after 40 days
the price = $35 per share
let say it is modeled by
y = ax² + b x + c
x = number of days
y = stock price
x = 0 y = 20
20 = a x 0 + b x 0 + c
c = 20
x = 20 y = 30
30 = 20² a + 20 b + 20
400 a + 20 b = 10...........(1)
x = 40 y = 35
35 = 40² a + 40 b + 20
1600 a + 40 b = 15...........(2)
solving equation (1)and (2)
a = - 1/160
b = 5/8
hence , the above equation is multipart function
Answer:
390
Step-by-step explanation:
We know that the top is a rectangle triangle, we only have two of the tree sides and the one that is missing is the hypotenuse. The formula to find it is
If we put the values we know it would be
= 13
So now we have the lenght missing.
The area of the top and bottom is the same and we found it by the formula =
= 30, that is the area of just one triangle, multiply by 2 and that is the area of top and bottom = 30 x 2 = 60
The area of a rectangle is base x height, we have three rectangles.
First one: 13 x 11 = 143
Second one: 5 x 11 = 55
Third one: 12 x 11 = 132
The sum of the areas would be = 60 + 143 + 55 + 132 = 390
If you are constanly loosing points nd at the end you have lost 165, you lost 11 points every minute
