Consider the problem of finding the line of symmetry and vertex of the quadratic equation f(x) =x^2-8x+15 What is the error in t
Jet001 [13]
We are given the quadratic:

f(x)=x^2-8x+15, with a=1, b=-8, c=15.


We know that the x-coordinate of the vertex, which is the point where the line of symmetry passes through is 

                                  \displaystyle{  -\frac{b}{2a}.

Thus, the x-coordinate of the vertex is -\frac{b}{2a} =-\frac{-8}{2\cdot1}= \frac{8}{2}=4.

Thus, the line of symmetry is x=4.


Answer: <span>B. The line of symmetry should have been 4 instead of –4. </span>

If the mass of two objects is increased, what is the effect on the force between them?
almond37 [142]

Answer:

A

Step-by-step explanation:

The formula used for this type of question is

F = \frac{Gm_1m_2}{r^2}  

so as long as you don't change anything else (like r), changing m will increase the force. Both of the last 2 answers look like they might be feasible, but they are not. The attraction increases.

So the answer is A
