The correct inequality is (4).
Answer:
A,B,D
Step-by-step explanation:
Any transformation that involves a dilation (that doesn't have scale factor equal to 1) will result in a similar a congruent figure.
A dilation shrinks or stretches a figure. So this means it creates a figure that is similar to, but not congruent to, the original figure.
Answer:
f(x) = x^3 + x^2 - 33x + 63
Step-by-step explanation:
The zeros are x = 3, x = 3, x = -7.
A polynomial function with zeros x1, x2, x3, ..., xn has the form:
f(x) = (x - x1)(x - x2)(x - x3) ... (x - xn)
The zeros of this function are 3, 3, -7.
The function is:
f(x) = (x - 3)(x - 3)(x - (-7))
f(x) = (x - 3)(x - 3)(x + 7)
Now we multiply out the right side.
f(x) = (x^2 - 6x + 9)(x + 7)
f(x) = x^3 + 7x^2 - 6x^2 - 42x + 9x + 63
f(x) = x^3 + x^2 - 33x + 63
Yes....because a terminating decimal can be turned into a fraction, making it rational
