Answer:
Lebeled Price of watch = Rs. 2000
Selling price pf the watch = Rs. 1600
Step-by-step explanation:
- ∴ S = L - 20% L
- ∴ S = 0.8 L ..... (1)
- ∴ S = P + (1/3)P
- ∴ S = (4/3) P ..... (2)
- As we know, P = 1200
- ∴ S (4/3) × 1200
- ∴ S = Rs. 1600
- 1600 = 0.8L
- ∴ L = 1600 ÷ 0.8
- ∴ L = Rs.2000
- ∴ Lebeled Price of watch = Rs. 2000
- Selling price pf the watch = Rs. 1600
Do you understand trigonometry ? (sine, cosine, tangent)
F(-1) is the inverses of an equation so plug in y for x.
Answer:
Average rate of change = 0
Step-by-step explanation:
f(z) = -2z^2 - 12z - 19
a = -4 and b = -2
[f(b) - f(a)] / (b-a)
[-2(-2)^2 - 12(-2) -19] - [-2(-4)^2-12(-4)-19] / (-2 -(-4))
(-8+24-19) - (-32+48-19) / 2
(-8+24-19+32-48+19) / 2 = 0/2
