This parabola has a minimum (since the coefficient of x^2 is positive). To find the vertex of a quadratic equation ax^2 + bx + c =0, you calculate (-b/a) or in our case (-6/4) = -3/2. This is the value of x. Now to find the value of y, you just plug x by its value (-3/2) & you'll find y =(-25/2) so the coordinate of the vertex are (-3/2 , -25/2).

Hope this is clear

If log(16)=s, what is the value of 2/3 log(6400) - 1/3 log(1600) in terms of s?

eduard

The value of $\dfrac{ 2}{3} log(6400) - \dfrac{1}{3} log(1600)$ in terms of s will be

$\dfrac{2}{3}(400s)-\dfrac{1}{3}(1000s)$

<h3>What is Logrithm?</h3>

A quantity representing the power to which a fixed number (the base) must be raised to produce a given number.

Here we have the expression:-

$\dfrac{ 2}{3} log(6400) - \dfrac{1}{3} log(1600)$

So in terms of s the expression will become:-

$\dfrac{2}{3}(400s)-\dfrac{1}{3}(1000s)$

3+ jk + k*3 when j=2 and k=6

Licemer1 [7]

The answer is 39, jk=18 because j multiplied by k is 18 and then i added 3 and i got 21, then k (6) multiplied by 3 is 18, so then i added 21 and 18 and i got 39
