The dimensions of a room are 20 ft by 18 ft, respectively. Find the length across the diagonal of the room.
1 answer:
Answer:
26.91 ft
Step-by-step explanation:
Well you can do this using the Pythagorean theorem and apply this to your room, which is a rectangle.
Diagonal = √h²+w²
where: h = height and w = width
So we insert our given:
Diagonal = √(20ft)²+(18)²
= √400ft² + 324ft²
= √724ft²
= 26.91ft
You can look below to see the scenario.

<em>Greetings from Brasil...</em>
In a trigonometric function
F(X) = ±UD ± A.COS(Px + LR)
UD - move the graph to Up or Down (+ = up | - = down)
A - amplitude
P - period (period = 2π/P)
LR - move the graph to Left or Right (+ = left | - = right)
So:
A) F(X) = COS(X + 1)
standard cosine graph with 1 unit shift to the left
B) F(X) = COS(X) - 1 = -1 + COS(X)
standard cosine graph with 1 unit down
C) F(X) = COS(X - 1)
standard cosine graph with shift 1 unit to the right
D) F(X) = SEN(X - 1)
standard Sine graph with shift 1 unit to the right
Observing the graph we notice the sine function shifted 1 unit to the right, then
<h3>Option D</h3><em>(cosine star the curve in X and Y = zero. sine start the curve in Y = 1)</em>
