Answer:
Step-by-step explanation:
The speed one (c) is a red herring. Nothing we can see measures her speed.
The only graph that could possibly represent the right answer is D (first graph from the right). It shows that she topped 1/2 way up. It also shows that she took her time about coming down when she was at the top.
The only thing we don't know is A. What's on the vertical axis?
Answer:
- determinant: -15
- x = 3; y = 4; z = 1
Step-by-step explanation:
The matrix of coefficients has one row corresponding to each equation. The constants in that row are the coefficients of the variables in the equation. Coefficients are listed in the same order on each row. A missing term is represented by a coefficient of 0.
<h3>coefficient matrix, determinant</h3>
The first attachment shows the coefficient matrix and its determinant.
__
<h3>solution</h3>
The solution to the system of equations can be found by left-multiplying the constant vector by the inverse of the coefficient matrix.
This multiplication is shown in the second attachment. It tells us ...
![\textbf{X}=\left[\begin{array}{c}x\\y\\z\end{array}\right]=\left[\begin{array}{c}3\\4\\1\end{array}\right]](https://tex.z-dn.net/?f=%5Ctextbf%7BX%7D%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7Dx%5C%5Cy%5C%5Cz%5Cend%7Barray%7D%5Cright%5D%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D3%5C%5C4%5C%5C1%5Cend%7Barray%7D%5Cright%5D)
The question is very vague, but here's what it tells me.
We know that the coordinates are (4, 25) meaning the x is 4 and the y is 25.
Since time is x and height is y, all this is saying is this:
After 4 weeks, the corn stock is 25 inches.
You can go deeper and divide 25 by 4 to find out the rate of growth. That would give you 6.25, meaning
The corn stock grows 6.25 inches every week.
Answer:
The answer should be B
Step-by-step explanation:
to find the net change you need to do final minus initial. So the final would be Jakarta and the initial would be Hong Kong. so just subtract Jakarta's latitude from Hong Kong's and the same for longitude
(x + 2) = 3
-2 -2
0 1
x = 1
