y = 3(x + 4)^2 + 31
Step-by-step explanation:
We can convert the given quadratic equation into its vertex form by completing the square:
y = 3x^2 + 24x + 43
= 3(x^2 + 8x) + 43
= 3(x^2 + 8x + 4) + 31
= 3(x + 4)^2 + 31
This is the vertex form of the given quadratic equation with (-4, 31) as its vertex
Answer:
56
Step-by-step explanation:
7 heartbeats *8 minutes = 56
Substitute -3 to x
(-3)^2 + 4(-3) + 1
9 - 12 + 1
= -2
48 feet
Divide 858 by 18 to get 47.6 > simplify > 48 feet
Answer:
Step-by-step explanation:
Given that
We have slope of linear regression line is
So regression line would be of the form
(since it passes through xbar, y bar)
is the equation of regression line.
