Answer:
1.72
Step-by-step explanation:
AB tangent at D, AD = OD = 4
so triangle OAD is right angle with side of 4 and 4.
area of OAD = 1/2 * 4 * 4 = 8
Angle AOD = DAO = 45 deg.
so circular sector OCD area = area of circle O * 45/360
= pi * 4 * 4 * 45/360
= 2pi
Shade area ACD = trigangle OAD - circular sector OCD
= 8 - 2pi
= 1.72
3x²–243=0 —> 3 (x²–81) = 0 —>
x²–81=0 —> (x-9)(x+9)=0
x-9=0 —> x=9
x+9=0 —> x=–9

Answer:
The answer is C
Step-by-step explanation:
2x + 4y
2 x 3 = 6
4 x 6 = 24
24 + 6 = 30
If in 2 years, your car is worth $15000, then x2 so then you’ll make it 4 years. $15000+$15000= $30000 but then you’ll have to know what the last year is so since in 2 year your car turned $15000 more then you divide it by 2 which is $7500. Then, you add $15000+$15000+$7500 which is $37,500.
Step-by-step explanation:
The particle is at rest when the derivative of x(t), which is its velocity, is zero, i.e.,
![\dfrac{d}{dt}[x(t)] = \dot{x}(t) = 0](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%7D%7Bdt%7D%5Bx%28t%29%5D%20%3D%20%5Cdot%7Bx%7D%28t%29%20%3D%200)
Since 
its derivative is
Equating this to zero, we get
This is a familiar quadratic equation whose roots are
This means that the particle will be at rest at t = 3 and t= 4.
