Answer choices?...........
We are given the points
<span>(0,-4),(1,0),(2,2)
The standard form a quadratic function (in terms of x) is
y = Ax2 + Bx + C
Subsitute the points
-4 = 0 + 0 + C
C = -4
0 = A + B - 4
2 = 4A + 2B - 4
Solve for A and B
A = -1
B = 5
The function is
y = -x2 + 5x - 4</span>
Negative 9 because 51 - 60 = 9
Answer:
Both sides of the first equation are divided by 10 to get the 2nd question so on and so forth...
Answer:
Step-by-step explanation:
we know that
The area of the resulting two-dimensional cross-section is the area of a rectangle
The area of a rectangle is equal to
we have
