V=lwh solve for l in literal equations

1 answer:

5 0

Basically, you just perform whatever operations are needed to get the variable you DON'T know by itself on one side of the equal sign, plug in the variables you do know, and you have it. In your example, say you don't know the length, but you know the others:
V = l*w*h
V/w*h = l*w*h/w*h
V/wh = l
Now l is by itself, so you can substitute values for the other variables and solve for l.

The initial size of the population is 300. After 1 day the population has grown to 800. Estimate the population after 6 days. (R

Cloud [144]

Solution :

Given initial population = 300

Final population after 1 day = 800

Number of days = 6

∴ $\frac{dP}{dt} =kt^{1/2}$

P(0) = 300 P(1) = 300

We need to find P(8).

$dP = kt^{1/2} dt$

$\int 1 dP = \int kt^{1/2} dt$

$P(t) = k \left(\frac{t^{3/2}}{3/2}\right)+c$

$P(t)= \frac{2k}{3}t^{3/2} + c$

When P(0) = 300

$300 = \frac{2k}{3} (0)^{3/2} + c$

∴ c = 300

∴ $P(t)= \frac{2k}{3}t^{3/2} + 300$

When P(1) = 800

$800 = \frac{2k}{3} (1)^{3/2} + 300$

$500 = \frac{2k}{3}$

∴ k = 750

$P(t)= 500t^{3/2} + 300$

So, P(8) is

$P(t)= 500(8)^{3/2} + 300$

= 11,614

So the population becomes 11,614 after 8 days.

45min/hour = ___ ft/seconds

emmasim [6.3K]

The answer to your question is 45 miles / 1 hour * 5280 feet / 1 mile * 1 hour / 3660 seconds = 45 * 5280 * 1 / 1 * 1 * 3660 = 2737600 feet / 3660 second = 64.918
