-√5 ≈ -2.23 . . . . calculator

There are many ways to describe the result of a comparison of numbers: difference, percentage difference (using either as a base), greater/less than, ratio, and more.

We'll take the simplest, and say

... -1.96312 > -√5

The population of deer forest is currently 800 individuals. Scientists predict that this population will grow at a rate of 20 pe

jonny [76]

Answer:

C. 3.8 years

Step-by-step explanation:

Exponential Growth

The natural growth of some magnitudes can be modeled by the equation:

$P(t)=P_o(1+r)^t$

Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.

The actual population of deer in a forest is Po=800 individuals. It's been predicted the population will grow at a rate of 20% per year (r=0.2).

We have enough information to write the exponential model:

$P(t)=800(1+0.2)^t$

$P(t)=800(1.2)^t$

It's required to find the number of years required for the population of deers to double, that is, P = 2*Po = 1600. We need to solve for t:

$800(1.2)^t=1600$

Dividing by 800:

$(1.2)^t=1600/800=2$

Taking logarithms:

$t\log 1.2=\log 2$

Dividing by log 1.2:

$t=\frac{\log 2}{ \log 1.2}$

Calculating:

t = 3.8 years

Susan is 50 inches tall. myra is 3 inches taller than elanie,who is 2 inches shoerter than susan. how tall is myra

adoni [48]

Myra is 51 inches tall.

We'll use Susan as our base for this. She is 50 inches tall, and ignoring Myra or now, we move on to Elanie, who is said to be 2 inches shorter than Susan - therefore, Elanie is 48 inches tall. Now that we know this, we can return to Myra's information which says she is 3 inches taller than Elanie, which would mean she is in fact 51 inches tall.
