u still doing it or no just txt if ur not
For (x1,y1) and (x2,y2)
slope=(y2-y1)/(x2-x1)
(4,19)
(7,28)
slope=(28-19)/(7-4)=9/3=3/1=3
because math
X = 3 Right side length!
I hope this helps. :)
Answer:
<u>-12x³</u>
(x⁴ +1)⁴
Step-by-step explanation:
y=1/(x^4+1)^3
y= (x⁴+1)-³
<u>dy</u><u> </u>= <u>d</u><u>(</u><u>x⁴</u><u>+</u><u>1</u><u>)</u><u>-</u><u>³</u> × <u>d</u><u>(</u><u>x</u><u>⁴</u><u>+</u><u>1</u><u>)</u>
dx d(x⁴+1) dx
=-3.(x⁴+1)-³-¹× 4x³
= -12x³(x⁴+1)-⁴
= <u>-</u><u>12</u><u>x</u><u>³</u>
(x⁴+1)⁴
Note: <u>d</u><u>x</u><u>^</u><u>n</u><u> </u> =(n. x^n-1)<u>dx</u>
dx dx
