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:
A- b: the y value when y changes; the point where a line crosses the v-axis
B- m: What happens to y when x is one; the ratio of the y change to the x change
C- k: The y value when x is zero b x increases by one
Step-by-step explanation:
If this is about slope intercept form as i think it is
C sounds a little bonkers in this case though because when y is zero then x increases by one
The domain is B. -8 ≤ x < 3 and 4 ≤ x < 8
Step-by-step explanation:
mean = sum of observation/ no. of observation
mean = 3+5+6+4+7+3+9+8/ 8
<h2>mean = 45/8 = 5.6</h2>
<span>There are a few combinations of mixed numbers that can have a sum of 3. A mixed number must have one whole number and one fraction. Combinations of mixed numbers that can have a sum of 3 are 1 and 1/2 + 1 and 1/2, 1 and 1/3 + 1 and 2/3, 1 and 5/8 + 1 and 3/8 and so on.</span>
