Answer:

16.86°

Step-by-step explanation:

Given the value for sin(a) = 0.29, we need to find the angle, in this case, a, whose sin(a) = 0.29.

In other words, we need to find <em>the inverse function</em> for the function in question.

In this case, the inverse function of <em>sin(x)</em> is <em>arcsin(x) </em>(which is also commonly known as \\ sin^{-1}(x)).

So, for \\ sin(a) = 0.29, we can find the function \\ sin^{-1}(x) in a digital calculator, or asking WolframAlpha in Internet, so we have that \\ sin^{-1}(0.29)=16.86 degrees (°).

In fact, we can check this result for a = 16.86°:\\ sin(16.86) = 0.29.

In other words, we found that 16.86° is the <em>angle in degrees</em> whose \\ sin(16.86) = 0.29.

<u>One word of caution</u>: we need to be careful about if we are using <em>degrees</em>  (known for this symbol ° ) or <em>radians</em> when calculating <em>angles</em>.

In the past, people were used to consult large tables with values for \\ sin(x), cos(x), tan(x) and so on, and looking for the <em>angle</em> that generated such a value of \\ sin(x), cos(x), tan(x), respectively.

There are many other cases in which we have inverse functions, for example, logartithm is the inverse function of exponential function.

What is the present value of $4,900 per year at a discount rate of 10 percent if the first payment is received 6 years from now
Nesterboy [21]

Answer:

17640

Step-by-step explanation:

at a discount of 10% per year $4900 is equal to $490 per year

payment started 6 years ago from now and ended 20 years from now

therefore there is an accumulation of 26 years

for 26 years = 26 *$490= $12740

present value therefore = $4900+$12740=$ 17640

Round to the nearest thousand and then add the rounded numbers. <br><br> 8794<br> +312
lyudmila [28]

Answer:

4.0148 rounded to the nearest thousand is 0, but if you meant rounded to the nearest thousandth, it would be 4.015 because the 8 in the ten thousandth column would cause the 4 in the thousandth column to round up to 5.
