F=5/9c+32<br> Solve for c

arsen [322]

F = (5/9)c + 32
F - 32 = (5/9)c
9(F-32) = 5c

(9(F-32))/5 = c

The number of citizens in a town is growing according to a linear growth model. The initial population in week 0 was P_0=124 and

il63 [147K]

184 - 124 = 60
so it has grown by 60 in 18 months. That is 3 1/3 per month.

so Number of citizens depending on month is 124 + (1 1/3)n
or 124 + 4n/3:

At population 1000:-
124 + 4n/3 = 1000
4n/3 = 1000-124

n = (1000-124) * 3/4 = 657 months

A 200-liter tank initially full of water develops a leak at the bottom. Given that 20% of the water leaks out in the first 5 min

Leya [2.2K]

Answer:

127.53 liters left after 10 minutes

Step-by-step explanation:

Let

$A \to Amount$

$t \to time$

Given

$A(0) = 200$ --- initial

$A(5) = 200 * (1 - 20\%) = 160$ --- the amount left, after 5 minutes

Required

$A(10)$ --- amount left after 5 minutes

To do this, we make use of:

$A(t) = A(0) * e^{kt}$

$A(5) = 160$ implies that:

$160 = 200 * e^{k*5}$

Divide both sides by 200

$0.80 = e^{k*5}$

Take natural logarithm of both sides

$\ln(0.80) = \ln(e^{k*5})$

$\ln(0.80) = \ln(e^{5k})$

$\ln(0.80) = 5k\ln(e)$

So, we have:

$-0.223 = 5k$

Divide by 5

$k = -0.045$

So, the function is:

$A(t) = A(0) * e^{kt}$

$A(t) = 200 * e^{-0.045t}$

The amount after 10 minutes is:

$A(10) = 200 * e^{-0.045*10}$

$A(10) = 200 * e^{-0.45}$

$A(10) = 127.53$
