When a zero of a function does not cross the x-axis but touches it, this means that the zero is a "double root". It has two of the same factor (x - 4)^2 and two of the same zeros, x = 4 and x = 4
f(x) = x^2 - 8x + 16 would be the function with a double root at 4
Hello there!
The answer to your question is A. <span>1.75 in.</span>³
The ball split, so now the diameter is 1.50 in. The radius is always half of the diameter. So now, do the volume formula for a sphere. You answer should turn out to be A.
Hope I helped!
M=25
x1=-4
y1=-7
y-y1=m(x-x1)
y-(-7)=25(x-(-4))
y+7=25(x+4)
