Answer:

Step-by-step explanation:

3x^{2}+x-3= x^{2} - 5x

The number of board feet in a 16 foot long tree is approximated by the model F(d) = 0.77d^2 -- 1.32d -- 9.31 where F is the numb
Lubov Fominskaja [6]

we are given

F(d)=0.77d^2-1.32d-9.31

where

F is the number of board feet

d is the diameter (in inches) of the log

Since, we have to minimize F

so, firstly we will find it's derivative

F'(d)=0.77\times 2d-1.32\times 1-0

F'(d)=1.54d-1.32

now, we can set it to 0

and then we can solve for d

F'(d)=1.54d-1.32=0

1.54d-1.32=0

so, we get diameter as

d=\frac{6}{7}inch..............Answer

Find the slope of the line containing the points in the table below
zhannawk [14.2K]

Answer:

slope = 3

Step-by-step explanation:

Choose any two points: For example, (2, 4) and (4, 10)

Find the difference in y. This is called the "rise."

rise = 10 - 4 = 6

In the same order, find the difference in x. this is called the "run."

run = 4 - 2 = 2

slope = rise/run

slope = 6/2

slope = 3
