If x2 + y2 = 25, what is the value of
at the point (4,3)?
o a. -25/27
ob.-7/27
oc. 7/27
d. 3/4
oe. 25/27

A. -25/27

Step-by-step explanation:

Given:

The equation is given as:

To find: at (4, 3)

Differentiating the above equation with respect to 'x', we get:

Value of at (4,3) is given as:

Now, differentiating equation (1) with respect to 'x' again, we get:

Now, value of at (4,3) is given as by plugging 4 for 'x', 3 for 'y' and for

Therefore, the value of the second derivative at (4, 3) is option (A) which is equal to -25/27.

true? is that what you're asking or do you mean something else?

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
