musickatia [10]

Answer:

25 in ^2

Step-by-step explanation:

First find the area of the circle

A = pi r^2

A = 3.14 ( 4.3)^2

A =58.0586

The take the fraction of the circle that is shaded

A circle is 360 degrees

155/360

155 /360 * the total area = area shaded

31/72 * 58.0586 = 24.99745278 in ^2

Rounding yields 25 in ^2

If a(x) = 3x + 1 and b (x) = square root of x-4, what is the domain of (b o a)(x)

Monica [59]

( 1, ∞) is the domain of (b o a)(x)

<h3>What is Function?</h3>

A function is defined as a relation between a set of inputs having one output each.

According to the question,

$a(x) = 3x + 1 \\\\b (x) =\sqrt{x+4}$

To find the domain of the composite function,

$(b o x) (x) = b(a(x))\\\\(b o x) (x) = b(a(3x-1))\\\\(b o x) (x) = \sqrt{3x+ 1 -4} \\\\(b o x) (x) = \sqrt{3x -3}\\\\$

Therefore,

$3x - 3 \geq 0\\3x \geq 3\\x \geq 1\\\\$

Hence , [ 1, ∞ ] is is the domain of (b o a)(x).
