Answer:

The radian is a unit of measure for angles used mainly in trigonometry. It is used instead of degrees. ... As seen in the figure above, a radian is defined by an arc of a circle. The length of the arc is equal to the radius of the circle. Because of this the radian is a fixed size no matter what the size of the circle is.

Answer:

$y=e^{-3t}(A\: cos\: t+B\:sin\:t)$

Step-by-step explanation:

<u>Given Second-Order Homogenous Differential Equation</u>

$y''+6y'+10y=0$

<u>Use Auxiliary Equation</u>

<u /> $m^2+6m+10=0\\\\(m+3)^2+1=0\\\\(m+3)^2=-1\\\\m+3=\pm i\\\\m=-3\pm i$

<u>General Solution</u>

<u /> $y=e^{pt}(A\: cos\: qt+B\:sin\:qt)\\\\y=e^{-3t}(A\: cos\: t+B\:sin\:t)$

Note that the DE has two distinct complex solutions $p\pm qi$ where $A$ and $B$ are arbitrary constants.

There are 680 raisins in 8 bags. If each bag has the same number of raisins, how many raisins are in 12 bags?

dmitriy555 [2]

Answer:

1020 raisins

Step-by-step explanation:

The problem tells you the number of raisins is proportional to the number of bags, so there will be "r" raisins in 12 bags:

r/12 = 680/8 = raisins/bag

r = (12/8)(680) = 1020

There will be 1020 raisins in 12 bags.
