Where v is velocity/speed
f is frequency
and lambda is wavelength
v=(500)(0.5)= 250 m/s
Hope this helps!
Question: The demand function for widgets is given by D(P) = 16 − 2P. Compute the change inconsumer surplus when price of a widget increases for $1 to $3. Illustrate your result graphically
Answer:
For price of a widget equal to $1 consumer surplus is
D(1) = 16 - 2(1) = 14
CS₁ = ½ × (8 – 1) × D(1) = ½ × 7 × 14 = 49.
When price is equal to $3 consumer surplus is
D(3) = 16 - 2(3) = 10
CS₃ = ½ × (8 – 3) × D(3) = ½ × 5 × 10 = 25
Answer:
A
Explanation:
Lower class can not usually afford store like this. Hence why they are called lower class
<span>25 years: No Payment, but total is 250000
6 months earlier. Payment of "P". It's value 1/2 year later is P(1+0.03)
6 months earlier. Payment of "P". It's value 1 year later is P(1+0.03)^2
6 months earlier. Payment of "P". It's value 1½ years later is P(1+0.03)^3
6 months earlier. Payment of "P". It's value 2 years later is P(1+0.03)^4
</span><span>We need to recognize these patterns. Similarly, we can identify the accumulated value of all 50 payments of "P". Starting from the last payment normally is most clear.

<span>P(1.03) + P(1.03)^2 + P(1.03)^3 + ... + P(1.03)^50
That needs to make sense. After that, it's an algebra problem.
P[(1.03) + (1.03)^2 + (1.03)^3 + ... + (1.03)^50]
</span>
P(<span><span>1.03−<span>1.03^51)/(</span></span><span>1−1.03) </span></span>= <span>250000</span>
