Answer:

1. 11

2. -4.3

Step-by-step explanation:

I added both of the terms together and determined these answers. Negatives can be confusing but if there is something like this: -(- then imagine it as a +. That makes it easier and you can find them just as easy as you once had in simpler times! Hope this helps!

Step-by-step explanation:

-14-(-25)

-14+25 subracting a is adding

25-14=11

-12.5-(-8.2)

-12.5+8.2

8.2-12.5=-4.3

The rate of change of the population of a small town is dPdt=kP, where P is the population, t is time in years and k is the grow

MAXImum [283]

Answer:

P = 94800 inh (town population at t = 10)

Step-by-step explanation: We get:

dP/dt = kP (1)

Population in year 2 is 30000

Population in year 4 is 40000

From equation (1)

dP/P = kdt

Then

∫ 1/P dp = k ∫dt

Ln (P) = kt + c (2)

Now we know populations in years 2 and 4 then by subtitution

Ln (40000) = 4k + c

Ln ( 30000) = 2k + c

Subtracting these equation we have

Ln (40000) - Ln ( 30000) = 2k

Then we can get k ??

ln ( 40000/30000) = 2k k = 1/2 Ln ( 4/3)

Now weareable to find population when t = 10

Equation (2)

Ln (P) = kt + c and from previous data

Ln (40000) = 4k + c

ln (P) = 10* k + c

Ln (40000) = 4k + c

The same procedure

Ln (P) - Ln ( 40000) = 6k

Ln (P) - Ln ( 40000) = 6* 1/2 Ln ( 4/3)

Ln (P) - Ln ( 40000) = 3*Ln (4/3)

Ln [ P/ 40000 ] = 3*Ln (4/3)

Eliminating Ln on both sides of the equation

P / 40000 = (4/3)³

P = 40000 * (4/3)³

P = 40000 * 2.37

P = 94800 inh (town population at t = 10)

An isosceles trapezoid was broken into a rectangle and two triangles. What are the base and height of one of the triangles?

Serga [27]

Answer:

base = 2 m; height = 6 m

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

Given the information:

base of 8 meters
height of 6 meters
top side length of 4 meters.

=> the height of one of the triangles equal to the the height of the trapezoid = 6 meters

=> the base of the triangles:

= (the base of the trapezoid - the top side length) / 2

= (8-4)/2

= 2

So the base and height of one of the triangles : base = 2 m; height = 6 m

Hope it will find you well.
