The inequality equation would be 482.75+82.25x1250 <span>subtracting the amount that Hannah already has from the goal would amount to 767.25, therefore she only needs to save up to equal or more than this amount. Dividing this by 82.25 would then give us how many months this would take equal or greater than 9.33 months.</span>
Answer:
29
Step-by-step explanation:
30 - (2 - 4) ÷ (-2)
= 30 - (-2) ÷ (-2)
= 30 - 1
= 29
K - 2k = 15 + 1 + 6k - 2
-k = (15 + 1 - 2) + 6k
-k = 14 + 6k |subtract 6k from both sides
-7k = 14 |divide both sides by (-7)
k = -2
Answer:
a) The differential equation for the velocity is given by
(dv/dt) = k(250 - v)
b) v(t) = 250 - e⁽⁵•⁵² ⁻ ᵏᵗ⁾
With units of km/h
Step-by-step explanation:
Acceleration, a ∝ (250 - v)
But acceleration is widely given as dv/dt
(dv/dt) ∝ (250 - v)
(dv/dt) = k(250 - v)
where k = constant of proportionality
(dv/dt) = k(250 - v)
b) (dv/dt) = k(250 - v)
dv/(250 - v) = k dt
∫ dv/(250 - v) = ∫ k dt
- In (250 - v) = kt + c (where c is the constant of integration)
v(0) = 0; meaning, at t = 0, v = 0
- In 250 = 0 + C
c = - In 250 = - 5.52
- In (250 - v) = kt - 5.52
In (250 - v) = 5.52 - kt
250 - v = e⁽⁵•⁵² ⁻ ᵏᵗ⁾
v = 250 - e⁽⁵•⁵² ⁻ ᵏᵗ⁾
With units of km/h
