Then, add the elements that occupy the same position:
![H=\begin{bmatrix}{-1.8+1.32} & {-8.6+(-1.9)} & {} \\ {2.85+2.25} & {-1.4+0.0} & {} \\ {-1.8+(-6.2)} & {5.1+1.4} & {}\end{bmatrix}](https://tex.z-dn.net/?f=H%3D%5Cbegin%7Bbmatrix%7D%7B-1.8%2B1.32%7D%20%26%20%7B-8.6%2B%28-1.9%29%7D%20%26%20%7B%7D%20%5C%5C%20%7B2.85%2B2.25%7D%20%26%20%7B-1.4%2B0.0%7D%20%26%20%7B%7D%20%5C%5C%20%7B-1.8%2B%28-6.2%29%7D%20%26%20%7B5.1%2B1.4%7D%20%26%20%7B%7D%5Cend%7Bbmatrix%7D)
Solve
![H=\begin{bmatrix}{-0.48} & {-10.5} & {} \\ {5.1} & {-1.4} & {} \\ {-8} & {6.5} & {}\end{bmatrix}](https://tex.z-dn.net/?f=H%3D%5Cbegin%7Bbmatrix%7D%7B-0.48%7D%20%26%20%7B-10.5%7D%20%26%20%7B%7D%20%5C%5C%20%7B5.1%7D%20%26%20%7B-1.4%7D%20%26%20%7B%7D%20%5C%5C%20%7B-8%7D%20%26%20%7B6.5%7D%20%26%20%7B%7D%5Cend%7Bbmatrix%7D)
So, we find the element at address h31:
![H=\begin{bmatrix}{h11} & {h12} & {} \\ {h21} & {h22} & {} \\ {h31} & {h32} & {}\end{bmatrix}](https://tex.z-dn.net/?f=H%3D%5Cbegin%7Bbmatrix%7D%7Bh11%7D%20%26%20%7Bh12%7D%20%26%20%7B%7D%20%5C%5C%20%7Bh21%7D%20%26%20%7Bh22%7D%20%26%20%7B%7D%20%5C%5C%20%7Bh31%7D%20%26%20%7Bh32%7D%20%26%20%7B%7D%5Cend%7Bbmatrix%7D)
In this case, position h31 is - 8.0
No, the radius is not 3.14 . The radius is 1/2 of the diameter . . . That's 6 feet.
If you see 3.14 on the sheet, then that's the number you're supposed to use for pi .
The area of any circle is (pi) x (radius squared).
If the table were a full circle, its area would be (pi) x (6 squared) = 36 pi square feet.
But it's only half of that . . . 18 pi = (18) x (3.14) = <u>56.52 square feet</u>.
That's called the "area" of the table, not the "square feet" of the table.
And another thing: I see you're asking for the "closest" number. Don't ask me
how I know this, but I'm pretty sure that right under this question wherever you
copied it from, there's a list of choices, and when you posted the question, for
some reason you decided not to share the list.
Answer:
0 degrees
Step-by-step explanation:
when it is hour 12 and 0 minutes, the hour and minute hand will be on top of each other, so therefore it does not form an angle
Formula for mid point.
(x1/2+x2/2 , y1/2+ y2/2)
Mid point=
(1/2+ (-3)/2 , 4/2+ 7/2)
(-2/2 , 11/2)
(-1, 5.5)
X=-4y+2
3(-4y+2)+2y=11
-12y+6+2y=11
-10y+6=11
-6=-6
-10y=5
y=-1/2
3x+2(-1/2)=11
3x-1=11
+1=+1
3x=12
x=4
Solution:(-1/2,4)
