Your answer is 192,000

3.9 percent of 200,000 is 7,800
200,000-7,800=192,000

Find the vertex by using the formula -b/2a
To find a and b, we must know that a and b are located at y = ax^2 + bx + c.
We find that b is 4 and a is 1 by looking at the given quadratic function.
The answer is A. -4/2(1) because the question is looking for the correct steps to find the answer.

Which expression is equivalent to log3 c/9?

stepladder [879]

Hello!

There is an existing logarithmic property that states that $log \frac{M}{N}$ is equal to $log M-logN$ .

Following that property, we can tell that $log \frac{c}{9}$ would be equal to $log(c)-log(9)$ .

ANSWER: $log(c)-log(9)$ (third option)

Answer:

I believe it is 6

Step-by-step explanation:

If you think about it the opposite of 6 is -6

and the only one that is -6 is c

because it is in absolute value {6}

will be 6 but there is a negative sign which then you just bring that down and you would get -6

For any scalars $c_1,c_2$ , we have

$c_1\mathbf v\times c_2\mathbf w=c_1c_2\mathbf v\times\mathbf w$

So

$\left(-\dfrac34\mathbf v\right)\times\left(-\dfrac12\mathbf w\right)=\dfrac38\mathbf v\times\mathbf w$

We have

$\mathbf v\times\mathbf w=\begin{vmatrix}\mathbf i&\mathbf j&\mathbf k\\-2&12&-3\\-7&4&-6\end{vmatrix}$
$=\begin{vmatrix}12&-3\\4&-6\end{vmatrix}\mathbf i-\begin{vmatrix}-2&-3\\-7&-6\end{vmatrix}\mathbf j+\begin{vmatrix}-2&12\\-7&4\end{vmatrix}\mathbf k$
$=-60\,\mathbf i-(-9)\,\mathbf j+76\,\mathbf k$
$=\begin{bmatrix}-60\\9\\76\end{bmatrix}$

which makes

$\left(-\dfrac34\mathbf v\right)\times\left(-\dfrac12\mathbf w\right)=\dfrac38\begin{bmatrix}-60\\9\\76\end{bmatrix}=\begin{bmatrix}-\frac{45}2\\\\\frac{27}8\\\\\frac{57}2\end{bmatrix}$
