Answer:
64
Step-by-step explanation:
length(l)=8cm
breadth(b)=2cm
height(h)=4cm
volume=l×b×h
=8cm×2cm×4cm
=64cm³
<span>sinx - cosx =sqrt(2)
Taking square on both sides:
</span>(sinx - cosx)^2 =sqrt(2)^2<span>
sin^2(x) -2cos(x)sin(x) + cos^2(x) = 2
Rearranging the equation:
sin^2(x)+cos^2(x) -2cos(x)sin(x)=2
As,
</span><span>sin^2(x)+cos^2(x) = 1
</span><span>So,
1-2sinxcosx=2
1-1-2sinxcosx=2-1
-</span><span>2sinxcosx = 1
</span><span>Using Trignometric identities:
-2(0.5(sin(x+x)+sin(x-x))=1
-sin2x+sin0=1
As,
sin 0 = 0
So,
sin2x+0 = -1
</span><span>sin2x = -1</span><span>
2x=-90 degrees + t360
Dividing by 2 on both sides:
x=-45 degrees + t180
or 2x=270 degrees +t360
x= 135 degrees + t180 where t is integer</span>

Answer:
option d
Step-by-step explanation:
We are given with three function
Plug in x=-2 in first function
f(x)= 3 so f(-2) = 3
Plug in x=-2 in second function
Plug in x=2 in second function
Plug in x=2 in third function
f(x)= 2x-3
f(2)= 2(2) -3 = 1
We can see that f(-2)=3 is same for first and second function
also f(2) = 1 is same for second and third functions
So the graph is continuous
option D satisfies the points
Answer:
85
Step-by-step explanation:
if the top half is 180° and one side is 95° then the other side is 85°
