Answer:
12 inches
Step-by-step explanation:
let length be L
formula for perimeter of rectangle = 2( length + width )
2( L + 9) = 42
2L + 18 = 42
2L = 24
L = 12 inches
The measure of an angle is the coterminal angle with a 45A°+360A° and can be determined by using the measurement of coterminal angles.
<h2>We have to
determine</h2>
Which expression finds the measure of an angle that is coterminal with a 45° angle?
<h3>
According to the
question,</h3>
Coterminal angles are those angles that share the terminal side of an angle occupying the standard position.
The standard position means that one side of the angle is fixed along the positive x-axis, and the vertex is located at the origin.
<h3>A
coterminal with 45°
is
45°+k°360° with
k as an
integer.</h3>
Then,
The coterminal angle with 45°,
When k = 0
Then,

When k = 1
Then,

When k = -1
Then,

Hence, The measure of an angle that is coterminal with a 45A°+360A°.

Answer:
<u>Given is the piecewise function</u>
<h3>The first interval</h3>
<u>Domain:</u>
<u>The function</u>
<h3>The second interval</h3>
<u>Domain</u>
<u>The function</u>
- The slope is m = (0 - (-4))/(0 - (-2)) = 4/2 = 2
- The y-intercept is 0
- y = 2x
<h3>The third interval</h3>
<u>Domain</u>
<u>The function</u>
- The slope is m = (0 - 2)/(4 - 0) = - 1/2
- The y-intercept is 2
- y = -1/2x + 2
