Answer:

The population of Bear in 2050 is 4750000

Step-by-step explanation:

A) The exponential growth equation for bear is as follows -

dN/dT = rmax * N

Where dN/dT = change in population

rmax is the maximum rate of change

N = Base population

B) Here the per capita rate of increase (r) will always be a positive value irrespective of the and hence we will assume this population to be growing exponentially.

C) dN/dT = rmax * N

D) dN / 5 = 2.5 * 380,000

dN = 5*2.5 * 380000

= 4750000

The rate of change in y = 24x
Artyom0805 [142]

Answer:

24

Step-by-step explanation:

Using the formula y = mx + b we can find the slope or rate of change. First we must convert it into the formula or equation we currently have which is y = 24x + 0.

24 = m

x = x

0 = b

m is always the rate of change or slope so by finding m we find the slope or rate of change.

Xsquare + 10x + 16 equals 0
inn [45]
X^2+10x+16=0

First, you find factors of 16.
1 x 16
2 x 8
4 x 4

Next, you find which of the factor pairs adds up to 10 (from the 10x). In this case, 2 x 8 because 2 times 8 is 16 and 2 plus 8 is 10.

Then, the equation will be written out as: (x+2) (x+8). Take those two equations and set them equal to 0, and then solve.

x+2=0
-2 -2
x=-2

x+8=0
-8 -8
x=-8

So, your answers are x=-2 and x=-8. You can check by plugging in those two numbers as x.
