Maximum and Minimum Values of General Quadratic Functions
1 answer:
Answer:
x=-1
y=15
Step-by-step explanation:
This works because completing the square is essentially demonstrating what g(x) - where g(x) in this case = x^2 - would have to be translated by to give the function you have.
So by completing the square you have shown that the function you've been given has been shifted to the left by -1, stretched by a factor of 2 along the y axis and shifted up by 15.

Answer:
y = 8
x = 9
Step-by-step explanation:
given equation,
x + y = 17 ........(1)
9 x - y = 73...........(2)
writing in matrix form
A X = B
using augamented matrix A|B
using row transformation
R₂ = R₂ - 9 R₁
now,
now
-10 y = -80
y = 8
and
x + y = 17
x = 17 -8
x =9
Answer:
<h2>The Slant height of the pyramid is 7 yards.</h2>Step-by-step explanation:
The total surface area is 125 square yards.
The base area is 37.5 square yards.
Hence, the area of the curved surface is 125 - 37.5 = 87.5 square yards.
According, to the formula, the area of the curved surface is , where b is the base length and s = slant height.
Here, it is given that b = 5 yards.
Thus, .
