Recall that i represents the square root of -1, so by squaring it we get -1.

(2 + 4i)(7 - 3i)

= 14 - 6i + 28i + 12
= 26 + 22i

A population of 50 timber wolves was introduced into a forest in 2009. The population is expected to grow by the function p(t)=5
Viktor [21]

Answer:

the population in 2015 is 8201.0695

Step-by-step explanation:

Given that

There is a population of the 50 timber wolves

And, the exponential function given is

p(t) = 50 × e^(0.85 × t)

Here t denotes the time period i.e.

= 2015 - 2009

= 6

So,

= 50 × e^(0.85 × 6)

= 8201.095

Hence, the population in 2015 is 8201.0695

Water makes up about 60% of the average adult's body weight. Represent this percent by shading in the squares.
Viefleur [7K]

Answer:

shading three boxes

Step-by-step explanation:

It is given that :

The body weight of an average adult = 60%

We have to show this by shading the square boxes shown.

There are 5 square boxes in total which makes up 100%.

So divide 100 by 5, we can 20% for each box.

So, 20% + 20% + 20%  will give us 60%

Therefore, shading three boxes will give us 60% which is the water percent in an average adult's body weight.

This is represented by the figure below.
