Find the values of y which makes the expression (2y + 7) /(y2 - 2y - 15) undefined?
sammy [17]

The  given expression becomes undefined when y=5 or y = -3. The answer is option D.

Step-by-step explanation:

The value of the given expression becomes undefined when the denominator equals 0.

Hence to find the value of y which makes the expression undefined, we can equate the value of the denominator to zero and solve it .

Step 1

  Equate the denominator to 0.

  y^{2}  - 2y -15 = 0

Step 2

   Solve the above equation to get the value of y.

     y^{2}  - 2y -15 = 0

    => (y-5)(y+3) =0 [ Roots of the quadratic equation]

   => y = 5 or y = -3.

Hence when y = 5 or y = -3 the denominator becomes 0, which makes the expression (2y+7)/0  and hence it is undefined.

What is the answer to 3 divided by 74 in partial products
ddd [48]
All u do is divide 3 into 74 but 3 cant get into 74 so u do the number the close in that 3 times 24 in that 72 but if u do 25 times 3 that 75 in the number cant be greater so then u know it 24 times 3 then u subtract 74 from 72 in get 2 as the remainder so u have 2 as the hold number in 3 as the nemonator in 24 as the denatorator

I have 4 questions (please help) IM BEGGING YOU i need help! please!!!!

1) 18h = 252
You divide each side by 18, so you can get "h" alone on a side, and its value on the other side of the equation.
(18h)/18 = 252/18
h = 14 (Answer C)

2) 31d = 186.
Same Thing, you divide each side by 31, so you can get "d" alone on a side, and its value on the other side of the equation.
(31d)/31 = 186/31
d= 6 (Answer B)

3) 55c = 385
Again, same thing, You divide each side by 55, so you can get "c" alone on a side, and its value on the other side of the equation.
(55c)/55 = 385/55
c = 7 (Answer B)

4) 50w = 1050
You divide each side by 50, so you can get "w" alone on a side, and its value on the other side of the equation.
(50w)/50 = 1050/50
w=21 (Answer A)

As you can notice, they all follow the same steps: dividing by the coefficient of the variable both sides, so you can the variable alone on the first side of the equation, and its value on the second side.

Hope this Helps! :)

Find the volume of the region bounded above by the paraboloid z equals 3 x squared plus y squared and below by the square R: min
RideAnS [48]

Answer:

V=5.333cubit unit

Step-by-step explanation:

this problem question, we are required to evaluate the volume of the region bounded by the paraboloid z = f(x, y) = 3x² + y² and the square r: -1≤ x ≤ 1, -1 ≤ y ≤ 1

The question can be interpreted as z = f(x, y) = 3x² + y² and the square r: -1≤ x ≤ 1, -1 ≤ y ≤ 1 and we are told to evaluate the volume of the region bounded by the given paraboloid z

The volume V of integral evaluated along the limits of x and y for the 2-D figure, can be evaluated using the expression below

V = ∫∫ f(x, y) dx dy then we can now substitute and integrate accordingly.
