Hello :
y= <span>x² - 4x + 1
calculate : x
y = (x²-4x+4)-4+1
y+3 = (x-2)²
x exist : if y+3 </span><span>≥ 0
y </span><span>≥ -3
the range is : </span><span>{y: y ≥ -3}</span>
Answer:
i really dont know cause i nwed help too
Let's find both of the probabilities and multiply them.
First, we know that the theoretical P(Getting Heads) is 1/2, because there's two sides to a penny.
Next, we know that a dice has 6 sides, so P(Rolling a number greater than 2) is going to be 4/6, or 2/3.
Let's multiply our probabilities.
We have:
1/2 × 2/3, which get's us 2/6, or 1/3.
P(Flipping heads and rolling greater than 2) = 1/3.
Hope this helped!

ok if you any doubt say me
Answer:
Correct option: B -> 36
Step-by-step explanation:
The surface area of a circular cone is given by the formula:
Surface area = pi * radius * (radius + slant height)
If the inicial radius is 4 in and the slant height is 9 in, we have:
Surface area = pi * 4 * (4 + 9) = 52pi in2
The radius and the slant height are multiplied by 6, so we have:
radius = 6 * 4 = 24 in
slant height = 6 * 9 = 54 in
So the new surface area is:
New surface area = pi * 24 * (24 + 54) = 1872pi in2
The factor of the surface areas is:
New surface area / Surface area = 1872pi / 52pi = 36
Correct option: B
