Suppose f(x, y)=x^2+y^2â2xâ4y+3 a. How many critical points does f have in R2?
b. If there is a local minimum, what is the value of the discriminant D at that point? If there is none, type N.
c. If there is a local maximum, what is the value of the discriminant D at that point? If there is none, type N.
d. If there is a saddle point, what is the value of the discriminant D at that point? If there is none, type N.
e. What is the maximum value of f on R2? If there is none, type N.
f. What is the minimum value of f on R2? If there is none, type N.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

can someone me: the midsegment through the legs of an isosceles triangle is 4 in. find the sides of the triangle if its perimeter is 20 in. ,   and point g is the centroid of the right △abc with hypotenuse ab=18 in. find cg.

hey there! : )

4y < -4

we need to isolate y. we can do this by simply dividing both sides by 4.

4y ÷ 4 > -4 ÷ 4

simplify.

y > -1

5 - y > 0

once again, we need to isolate y, so we can start off by subtracting 5 from both sides.

5 - y - 5 > 0 - 5

simplify.

-y > -5

divide both sides by -1.

** remember that when dividing any side by a negative, you must switch the sign! **

-y ÷ -1 < -5 ÷ -1

simplify.

y < 5
