Hi, I'd be glad to help you with this equation.
Your answer is (5/ x + 3)
Hope this helps.
Have a great day!
Answer:
Point Critical point
Q (2,0) local minimum
R (-2,1) Saddle
S (2,-1) local maximum
T ( -2,-1) Saddle
O ( -2,0) Saddle
Step-by-step explanation: INCOMPLETE ANSWER INFORMATION ABOUT THE POINTS ARE RARE
f(x,y) = x³ +y⁴ - 6x -2y² +3
df/dx = f´(x) = 3x² -6x
df/dxdx = f´´(xx) = 6x
df/dy = f´(y) = -4y
df/dydy = 4
df/dydx = df/dxdy = 0
df/dydy = f´´(yy)
D = [ df/dxdx *df/dydy] - [df/dydx]²
D = (6x)*4 - 0
D = 6*2*4 D > 0 and the second derivative on x is 6*2 = 12
so D > 0 and df/dxdx >0 there is a local minimum in P
Q(2,1)
D = (6*2)*4 D>0 and second derivative on x is 6*2
The same condition there is a minimum in Q
R ( -2,1)
D = 6*(-2)*4 = -48 D< 0 there is a saddle point in R
S (2,-1)
D = 6*2*4 = 48 D > 0 and df/dxdx = 6*-1 = -6
There is a maximum in S
T ( -2,-1)
D = 6*(-2)*(4) = -48 D<0 there is a saddle point in T
O ( -2,0)
D = 6*(-2)*4 = -48 D<0 there is a saddle point in O
Answer:
40
Step-by-step explanation:
Surface area is the sum of the faces of all sides, so find the area of all sides and add
The area of given triangle is: 22.1184
Step-by-step explanation:
When we only know two sides of a triangle and the included angle then the area of triangle is given by:
Given
b = 9
c = 6
∠A = 125°
So the formula will be:
Hence,
The area of given triangle is: 22.1184

Because 3 multiplied by 3 is 9, 9 divided by 6 is 1.5
on the other question 9 multiplied by 1 is 9, divided by 6 is 1.5 as well
they have the same number result at the end
