Answer:
C. 3x^2 + 2x + 1
Step-by-step explanation:
A. 12^2 - (4*3*12) = 0 (there's one solution.)
B. (-3)^2 - (4*3*-18) = 255 (there're 2 real solutions.)
D. 3^2 - (4*0*-3) = 9 (there're 2 real solutions.)
C. 2^2 - (4*3*1) = -18 ✅✅
if b^2 - 4ac = negative then we can say that there isn't any real solution for the equation.
Answer:
The inverse is ±sqrt(100-x)
Step-by-step explanation:
y= 100 - x^2
Exchange x and y
x = 100 -y^2
Solve for y
Subtract 100 from each side
x-100 = 100-100-y^2
x-100 = - y^2
Multiply by -1
-x+100 = y^2
100 -x = y^2
Take the square root of each side
±sqrt(100-x) = sqrt(y^2)
±sqrt(100-x) = y
The inverse is ±sqrt(100-x)
Distance travel from house to bank=x
distance travel from bank to mall=y
distance travel from mall to house=√x²+y²
total distance=|x|+|y|+√x²+y²
Answer:
<h2>It doesn't change the volume.</h2>
Step-by-step explanation:
If we change the position of the vertex of a cone, it won't change its volume, because we're not changing its height.
When we change the position of the vertex of the cone, we are moving it to left or right, which would give a slant cone. However, its dimensions are the same. The important fact here is that the dimensions of the cone don't change, that's why it would give the same volume.
