The person is 5.5ft long
Reasoning: 30 divided by 6 equals 5
5 times 1.1 equals 5.5
Answer:
let g be f(x)
g= <u>4</u><u>x</u><u> </u><u>-</u><u>3</u>
. 7
make x the subject
<u>7</u><u>g</u><u> </u><u>+</u><u>3</u><u>. </u> =x
4
the inverse function of f(x) = <u>7</u><u>x</u><u>+</u><u>3</u>

The sum of the 3 inside angles of a triangle needs to equal 180:
11x-5 + 6x + 5 + c = 180
Combine like terms:
18x = 180
Divide both sides by 18:
X = 10
Solve for Q:
11x -5= 11(10) -5 = 110-5 = 105 degrees
I’m pretty sure your answer would be 36
Of the four x-coordinates to choose only 1/√(11) belongs can belong to the unit circle.
The other three x-coordinates are greater than 1, then they are out of the unit circle.
The unit circle formula is x^2 +y^2 = 1
Then to find the y-coordinate given the x-coordinate you can solve for y from that formula:
y^2 = 1 - x^2
y = (+/-)√(1-x^2)
Substitute the value of x
y = (+/-)√{1 - [1/√(11)]^2} = (+/-) √{(1 - 1/11} =(+/-) √ {(11 -1)/11 =(+/-)√(10/11) ≈ +/- 0.95
