The parent equation of the given graph is
where, n is any even number.
When this function is vertically shifted ( vertical dilation) down in the y- axis,
we get a graph similar to the one given in the question.
For example: ![y=\sqrt[2]{x}-2](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B2%5D%7Bx%7D-2)
The graph of the above function is attached below.
Parallel lines has equal slopes ii.e. slope of required line is 3.
Required equation is y + 1 = 3(x - 2) => y + 1 = 3x - 6
Area of triangle ABC can be found using the formula ¹/₂ × b × c × sin (A)
Substitute b = 9, c = 7, and m∠A = 66° into the formula gives
Area = 9 × 7 × sin 66° = 57.55
ANSWER: D
Do you have an example problem? I could help you there if you have one :)
SOH-CAH-TOA
sin Q = <u>Opposite</u> = <u>26</u>
hypotenuse x
sin 54 = <u>26</u>
x
x sin 54 = 26
<u>x sin 54</u> = <u> 26 </u>
sin 54 sin 54
x = <u> 26 </u> = 32.1378 ≈ 32.1 feet
sin 54
