Answer:
l = 5 cm
w = 8 cm
h = 3 cm
d = 9.89949 cm
S = 158 cm2
V = 120 cm<span>3
</span>l = length
w = width
h = height
d = diagonal
<span>S = surface area </span>
<span>V = volume</span>
Yes it is an exponential function as the value of y increases exponentially as x increases.
Volume=length*height*width
528=12*5.5*w
divide both sides by 12
44=5.5w
divide both sides by 5.5
8=w
width is 8 inches
Step-by-step explanation:
sin(x/2) = sqrt((1 - cos(x))/2)
cos(x/2) = sqrt((1 + cos(x))/2)
tan(x/2) = sin(x/2)/cos(x/2)
sin(x) = 15/17
so, we can assume the Hypotenuse of the right-angled triangle is 17, the vertical leg is 15.
via Pythagoras we get the 3rd, horizontal side :
17² = 15² + side²
289 = 225 + side²
64 = side²
side = 8
cos(x) = 8/17
sin(x/2) = sqrt((1 - 8/17)/2) = sqrt(9/34) = 3/sqrt(34) =
= 0.514495755...
cos(x/2) = sqrt((1 + 8/17)/2) = sqrt(25/34) = 5/sqrt(34) =
= 0.857492926...
tan(x/2) = 3/sqrt(34) / 5/sqrt(34) = 3/sqrt(34) × sqrt(34)/5 =
= 3/5 = 0.6
