The answer is ~0.556

Sin= opposite over hypotenuse.

To find the hyp., you use a squared plus b squared = c squared.

4+9=13

Square root of 13 is ~ 3.605

Now that you have your hyp, you can divide.

2 divided by 3.605 ~ 0.556 (rounded)

Hope this helps!!

The sine of the angle is the ratio of the opposite side to the hypotenuse. The hypotenuse of this triangle can be computed from the Pythagorean theorem:
.. AB = √(AC^2 +BC^2) = √(9 +4) = √13 . . . . cm
Then the ratio of opposite side BC to the hypotenuse AB is
.. sin(A) = BC/AB = 2/√13

Corresponds to the 3rd selection.

A bank advertises an interest rate of 4% per year, compounded monthly

Darina [25.2K]

Given :

Interest rate , r = 4 %.

To Find :

The APY .

Solution :

APY is given by :

$APY=(1+\dfrac{r}{n})^n-1$

Here , r is compound interest and n is number of time compounded .

So ,

$APY=(1+\dfrac{r}{n})^n-1\\\\APY=(1+\dfrac{4}{12})^{12}-1\\\\APY=30.57\%$

Therefore , APY is 30.57 % .

Hence , this is the required solution .

Meagan wants to make 2 1/3 batches of muffins. The recipe calls for 1 1/2 cups of sugar per batch. How much sugar will she need?

wlad13 [49]

Answer:

1 5/9 OR 14/9

Step-by-step explanation:

First we need to find out what the question is asking. How much sugar will she need if she wants to make 2 1/3 batches?

Next, we must see if we need to divide, subtract, multiply, or add. We need to divide.

2 1/3 divided by 1 1/2

Convert mixed numbers to improper fractions: 2 1/3=7/3 1 1/3=3/2

Apply the fraction rule a/b/c/d=a*d/b*c: 7*2/3*3

14/9 OR 1 5/9

well, looking at the picture of this vertically opening parabola, it has a vertex at 0,0 and it passes through 2,1 hmm ok

$~~~~~~\textit{vertical parabola vertex form} \\\\ y=a(x- h)^2+ k\qquad \begin{cases} \stackrel{vertex}{(h,k)}\\\\ \stackrel{"a"~is~negative}{op ens~\cap}\qquad \stackrel{"a"~is~positive}{op ens~\cup} \end{cases} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ y = a(x-0)^2+0\qquad \stackrel{\textit{we also know that}}{x=2\qquad y = 1}\qquad \implies 1=a(2-0)^2+0 \\\\\\ 1=4a\implies \cfrac{1}{4}=a~\hspace{10em} \boxed{y=\cfrac{1}{4}x^2}$
