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:
2x² + 3x + 4 + (17x + 9) / (x² − 4)
Step-by-step explanation:
Start by setting up the division. Make sure to write all the coefficients, even the zero ones.
x² + 0x − 4 | 2x⁴ + 3x³ − 4x² + 5x − 7
Start by dividing the first term of the dividend (2x⁴) by the first term of the divisor (x²). That's 2x²; it'll be the first term in quotient. Multiply the divisor by 2x²:
2x⁴ + 0x³ − 8x²
Subtract that from the first three terms of the dividend:
3x³ + 4x²
Drop down the next term from the dividend, and start the process all over again.
3x³ + 4x² + 5x
When you finish, the quotient will be 2x² + 3x + 4, and the remainder will be 17x + 9.

Step-by-step explanation:
Data
f(x) = -2x² + 8x - 2
Process
-2x² + 8x = y + 2
-2(x² - 4x + 4) = y + 2 - 8
-2(x - 2)² = y - 6
(x - 2)² = 1/2 (y - 6)
Vertex = (2, 6)
Axis of symmetry = x = 2
y-intercept
f(0) = -2(0)² + 8(0) - 2
f(0) = 0 + 0 - 2
f(0) = -2
Domain (-∞, ∞)
Range (-∞, 6]
