Answer:
Step-by-step explanation:
Hello : let A(-7,3) B(-6,-1)
the slope is : (YB - YA)/(XB -XA)
(-1-3)/(-6+7) = -4/1 =-4
an equation is : y=ax+b a is a slope
y = -4x +b
the line through point B (-6,-1) : -1 = (-4)(-6)+b
b = -25
the equation is : y =-4x-25

Answer: B) Only the first equation is an identity</h3>
========================
I'm using x in place of theta. For each equation, I'm only altering the left hand side.
Part 1
cos(270+x) = sin(x)
cos(270)cos(x) - sin(270)sin(x) = sin(x)
0*cos(x) - (-1)*sin(x) = sin(x)
0 + sin(x) = sin(x)
sin(x) = sin(x) ... equation is true
Identity is confirmed
---------------------------------
Part 2
sin(270+x) = -sin(x)
sin(270)cos(x) + cos(270)sin(x) = -sin(x)
-1*cos(x) + 0*sin(x) = -sin(x)
-cos(x) = -sin(x)
We don't have an identity. If the right hand side was -cos(x), instead of -sin(x), then we would have an identity.
Okay. first multiply 16*6*8. that's the volume of the prism that's standing. then do 16*16*4. that's the one on the left. now do 14*14*14. that's the one on the right. add all of them up and you should get 4,536 cm^3
