This is the best way to generate a random, relevant audience.
2) The population of interest consisted of the 1744 listeners that logged in and indicated their preference.</span>
Answer:
Maximum rate of change at the point (-1,2) = √17
Direction is the direction of the gradient
Step-by-step explanation:
The gradient of a function (scalar or vectorial ) is a vector in the direction of maximum rate of change then
f( x,y ) = x*2y + 2y
grad = δ/δx i + δ/δy j + δ/δz k
grad f(x,y) = [ δ/δx i , δ/δy] = [ 2y , x+2 ]
at the point ( -1 , 2 )
grad f(x,y) = [4 , 1]
| grad f(x,y) | = √ (4)² + (1)² = √17
Answer:
Sargento cheese slices are the better deal
Sargento cheese slices $2.48 for 10 slices = 0.248 per slice
Velveeta cheese slices $3.18 for 12 slices = 0.265 per slice
Step-by-step explanation:
Writing this statement symbolically, we get:
n
--- - 5 = 8
2
Adding 5 to both sides, we get n/2 = 13. Then n = 26.
