Define f(0,0) in a way that extends f to be continuous at the origin. f(x, y) = ln ( 19x^2 - x^2y^2 + 19 y^2/ x^2 + y^2) Let f (

kirill115 [55]

Answer:

f(0,0)=ln19

Step-by-step explanation:

$f(x,y)=ln(\frac{19x^2-x^2y^2+19y^2}{x^2+y^2})$ is given as continuous function, so there exist $lim_{(x,y)\rightarrow(0,0)}f(x,y)$ and it is equal to f(0,0).

Put x=rcosA annd y=rsinA

$f(r,A)=ln(\frac{19r^2cos^2A-r^2cos^2A*r^2sin^2A+19r^2sin^2A}{r^cos^2A+r^2sin^2A})=ln(\frac{19r^2(cos^2A+sin^2A)-r^4cos^2Asin^a}{r^2(cos^2A+sin^2A)})$

we know that $cos^2A+sin^2A=1$ , so we have that

$f(r,A))=ln(\frac{19r^2-r^4cos^2Asin^a}{r^2})=ln(19-r^2cos^2Asin^2A)$

$lim_{(x,y)\rightarrow(0,0)}f(x,y)=lim_{r\rightarrow0}f(r,A)=ln19$

So f(0,0)=ln19.

What is the average rate of change of the function f(x)=2(3)x from x = 2 to x = 4?

Dvinal [7]

this is kinda easy and im gonna assume that the 4 is a exponent cuz f(2)=2(3)^4 then f=81

The cost of 3 burritos is $22.50. If the cost is proportional to the number of burritos ordered,which of the following prices is

Assoli18 [71]

Answer:

A. 7 burritos for $51.50

Step-by-step explanation:

22.50/3=7.50

1 burrito cost $7.50

2 burritos will cost $15.00

2×7.50=15

5 burritos will cost $37.50

5×7.50=37.50

4 burritos will cost $30.00

4×7.50=30.00

However, 7 burritos will not cost $51.50 because 7×7.50=52.50 not 51.50
