Answer: AD = 108
BD = 105
ADB = 213
ABC = 182
<u>Step-by-step explanation:</u>
If no radius is given, assume it is length 1.
Then, the length of the arc is equal to the central angle.
Reminder that a circle is 360°

The central angle = 108°, so the arc length = 108

BD = BC + CD
= 35° + 70°
= 105°
The central angle = 105°, so the arc length = 105

ADB = AD + CD + BC
= 108° + 70° + 35°
= 213°
The central angle = 213°, so the arc length = 213

First, find the angle of AB.
AB = 360° - ADB
= 360° - 213°
= 147°
ABC = AB + BC
= 147° + 35°
= 182°
The central angle = 182°, so the arc length = 182
Answer:
Step-by-step explanation:
Given the function
y = (9x⁴ — 4x² + 6)⁴
We need to find the derivative of y with respect to x i.e. dy/dx.
So let u = 9x⁴—4x² + 6
Then y = u²,
Then, y is a function of u, y=f(u)
Also, u is a function of x, u = g(x)
In this case,
u = g(x) = 9x⁴—4x² + 6
So let differentiate this function y(x).
This is a function of a function
Then, we need to find u'(x)
u (x) = 9x⁴—4x² + 6
Then, u'(x) = 36x³ — 8x
Also we need to find y'(u)
Then, y = u²
y'(u) = 2u
Using function of a function formula
dy / dx = dy/du × du/dx
y'(x) = y'(u) × u'(x)
y'(x) = 2u × 36x³ — 8x
y'(x) = 2u(36x³ — 8x)
Since, u = 9x⁴—4x² + 6
Therefore,
y'(t) = 2(9x⁴—4x² + 6)(36x³ — 8x)
So,
dy/dx = 2(9x⁴—4x² + 6)(36x³ — 8x)
dy/dx = (18x⁴—8x² + 12)(36x³ — 8x)
