Sinα=h/L

α=arcsin(h/L)°  we are told that h=18 and L=20 so

α=arcsin(9/10)°

α≈64°  (to nearest whole degree)

Use related facts to determine whether the given value is a solution for each equation
solong [7]
For these questions it's asking you to substitute the value into the equation.
For example question 5 says,
26= y-9;y=35
basically it's saying if y=35, is the equation correct or not.
In this case: 26= 35 -9 is correct.
So your answer is true.
Hope this helps Xx

Simplify........................​
Ivahew [28]

Answer:

\frac {x^{3}-4x^{2}-20x+32}{x^{3}+2x^{2}-4x-8}

Step-by-step explanation:

make the denominator same

\frac{(x^{2}-4)(x-2)}{(x^{2}-4)(x+2) }-\frac{(2x+20)(x+2)}{(x^{2}-4)(x+2)}

then expand

\frac {x^{3}-2x^{2}-4x+8}{x^{3}+2x^{2}-4x-8} - \frac {2x^{2}+24x+40}{x^{3}+2x^{2}-4x-8}

join

\frac {x^{3}-4x^{2}-20x+32}{x^{3}+2x^{2}-4x-8}

i think but not sure

Megan has $500 in short-term savings, $5,000 in her retirement savings account, $500 in credit card debt, and student loan debt
laila [671]

Given, the amount Megan has in short term savings = $500.

The amount in retirement savings account = $5000.

The amount in credit card debt = $500.

The amount in student loan debt = $6500.

So total assets of Megan = Sum of short term savings and retirement savings.

Total asset = $500 + $5000 = $(500+5000) = $5500

Total liabilities of Megan = sum of credit card debt and student loan debt.

Total liability = $ 500 + $6500 = $(500+6500) = $7000

Now to find Megan's net worth we have to subtract total liability from total asset.

So Megan's net worth = $5500-$7000 = $(5500-7000) = $(-1500)

So we have got the required answer.

Net worth of Megan = -$1500.
