Which equation represents y= -x^2 + 6x + 7 in vertex form ?

Drupady [299]

we are given

$y= -x^2 + 6x + 7$

we can use vertex form parabola formula

$y= a(x-h)^2+k$

so, we can complete x square

$y= -(x^2 - 6x - 7)$

$y= -(x^2 - 6x - 7+3^2-3^2)$

$y= -(x^2 - 6x +3^2-16)$

$y= -(x-3)^2+16$

so, option-A........................Answer

Water has a density of 1.00g/cm^3 per cubic centimeter. What is the mass of half a liter of water?

anygoal [31]

Answer:

The mass of half a liter of water is 500g, that is, 0.5kg.

Step-by-step explanation:

Density is mass divided by the volume, that is:

$d = \frac{m}{v}$

Here, we have to be careful. Since the density is in grams per cm³, m has to be in grams and v in cm³.

We have that:

$d = 1$

What is the mass of half a liter of water?

One liter is 1000 cm³.

So half a liter is 1000/2 = 500 cm³, which means that $v = 500$

Then

$d = \frac{m}{v}$

$1 = \frac{m}{500}$

$m = 500$

The mass of half a liter of water is 500g, that is, 0.5kg.
