Answer:
-11x^8 + 3
Step-by-step explanation:
-8x^8 + (-3x^8 + 3)
-8x^8 - 3x^8 + 3
-11x^8 + 3
Answer:
b=12
Step-by-step explanation:
3b +24= b +48
-24 -24
3b = b+ 24
-b -b
2b = 24
÷2 ÷2
b=12

y=cos(2x)
<span>dy/dx=-2sin(2x) </span>
<span>dy/dx at the point x=pi/4 is </span>
<span>dy/dx=-2sin(2*pi/4) </span>
<span>dy/dx=-2 sin(pi/2) </span>
<span>dy/dx=-2 </span>
<span>therefore the slope of the tangent is -2
</span>
using this slope find the equation of the line
<span>(y-y')=m(x-x') </span>
<span>(y-0)=-2(x-pi/4) </span>
<span>y=-2(x-pi/4)</span>

Continuation of the answer
4x=180 degrees
X=180/4=45 degrees.
