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.

Answer:

  • True
  • True

Step-by-step explanation:

This question asks you to compare the coordinates of the vertex of each function.

__

The vertex of the function is its minimum, the point where the graph stops decreasing and starts increasing. It is the lowest point on the graph.

<h3>f(x)</h3>

The vertex is (-4, -1). The minimum is -1, located at x = -4.

<h3>g(x)</h3>

The vertex is (1, -25). The minimum is -25, located at x = 1. We know this is the minimum because there are no g(x) values that are lower (more negative).

<h3>comparison</h3>

The minimum of f(x), -1, is greater than the minimum of g(x), -25. TRUE

The x-value of f(x) at its minimum, -4, is less than the x-value of g(x) at its minimum, 1. TRUE

Answer this and I’ll mark you the Brainlest
Elena-2011 [213]

Answer:

D. 88

Step-by-step explanation:

if you add the given numbers up (equals 100) them subtract it from 540(the degrees of a Pentagon) you get 440. then divide that by 5 (number of xs left) you get 88. You can plug in 88 for x and check but I already did, I hope this helps you lemme know if it does :)

Which of the following is a result of shifting a circle with equation (x + 3)² + (y - 2)² = 36 left 3 units?
Furkat [3]
A circle with equation:
( x + 3 )² + ( y - 2 )² = 36
Center of a circle: C ( - 3, 2 )
r = 6 ( the radius of a circle stays the same )
After shifting 3 units left : C 1 ( - 6, 2 ).
Answer:
( x + 6 )² + ( y - 2 )² = 36

Can someone see if i did this correct? If not pls explain
Taya2010 [7]

Answer:

Not right.

Step-by-step explanation:

m <HGJ + m <KGJ =180°

So, m <HGJ = 180° - m <KGJ = 180° - 86° =94°
