If the score is 90% and the total is 70 what is the number correct ?

1 answer:

3 0

If you mean that the total number of questions is 70, then:

1. You need to figure out what 90% is of the total, 70.
2. Do this by multiplying 70 by 90% --> 70*(.9)
3. 90% of 70 is 63. The total number correct is 63.

You can check your work by figuring out what percentage 63 is of 70. 63 divided by 70 (63/70) is .9, or 90%.

Answer:

The parent function is $f(x)=a(x-h)^{2} +k$

That Parabola's equation is $f(x)=x^{2}$

Step-by-step explanation:

I can't really explain much, but the top equation is a formula for all equations for a parabola. h and k are the x and y-values of the vertex. a is, well, a.

How did I find the equation of the parabola? Simple. Since the vertex is on the origin, h and k are 0. Also, because it intercepts (2,4) and (1,1), a=1.

where $m$ is the mass and $v$ is the speed
