Answer:
x = 6
Step-by-step explanation:
We solve that above question using the trigonometric function of Tangent
Tan theta = Opposite/Adjacent
Theta = 45°
Opposite = 6
Adjacent = x
tan 45° = 6/x
tan 45 in rational form = 1
1 = 6/x
Cross Multiply
x = 6
Answer:
0.01 %
Step-by-step explanation:
The given model is;
y = a (0.5)^t/5730
Which is;
y = a(2^-1(t/5730)
Then;
y = a (2^-1/5730)^t
y = a(0.999879)^t
Hence;
Given that the general model is;
y(x)= a(1-r)^x
Where r is the rate percent
Since 1-r =0.999879
r = 0.00012096
y = a(1 - 0.00012096)^t
So;
r= 0.00012096* 100 = 0.01 %
The angle in the triangle = 60 degrees
so tan 60 = h / (1/2) s = 2h /s
sqrt3 = 2h / s
h = sqrt3 s / 2
B is the correct choice
