Answer:
49.1 cm² (round to nearest 10)
Step-by-step explanation:
- use trigonometry to find the <em>h</em><em>e</em><em>i</em><em>g</em><em>h</em><em>t</em><em>(</em><em>h</em><em>)</em><em> </em>of the triangle
- substitute height and base(b) 12cm into the formula
<em>A</em><em> </em><em>=</em><em> </em><em>½</em><em> </em><em>×</em><em> </em><em>b</em><em> </em><em>×</em><em> </em><em>h</em><em> </em><em>.</em>
Answer:
Step-by-step explanation:
We know that for two similar matrices 
and 
exists an invertible matrix 
for which
![[tex]B = P^{-1} AP](https://tex.z-dn.net/?f=%5Btex%5DB%20%3D%20P%5E%7B-1%7D%20AP)
[/tex]
∴ 
Also 
and 
∴
so, 
The hardest part is finding the length of the curve at the top. To find arc length, multiply the circumference by the arc angle divided by full angle (360°) in a circle. Or:
x, the arc angle in a semicircle, is 180°.
r, the radius is 7/2 = 3.5.
Now just plug the numbers in and solve for arc length, s.
s = 2π(3.5)(1/2) ≈ 11.00
Now just add up all the sides. 11cm + 10cm + 10cm + 7cm = 38 cm.
Start at 5 and go up 3 and move 4 to the right
She would by 3 packages of hot dogs and 2 packages of hot dog buns. This is because 3*8 would be 24 and 12*2 is also 24. These would both be the minimum amount of packages.
