Answer:
Step-by-step explanation:
To make the conjugate of a complex number, <em>change the sign of the imaginary part</em>. The imaginary part is the part that has <em>i</em> as a factor.
Your number has real part √2 and imaginary part -9i. Changing the sign of the imaginary part makes it be +9i, so the complex number becomes ...
We have the parent function:
y = x³ and we have to choose the correct answer to the question: which equation describes how is this function vertically stretched by a factor of 4.
y = x³ + 4 → The parent function is moved vertically 4 units up.
y = ( x + 4 )³ → The parent function is moved horizontally 4 units left.
y = x^4 → This is a different function.
Answer:
C ) y = 4 x³.
A median of a triangle is a segment that spans from the vertex to the midpoint of the opposite side.
Every triangle has three medians.
Answer:
Step-by-step explanation:
slope: (4-4)/(4-3)
slope: y=x+c
4=4+C
4-4=c
0=c
so y=x
