Answer:

$\large \boxed{\textbf{30.54 yr}}$

Step-by-step explanation:

For species A,

$P =2000e^{0.05t}$

For species B,

$P =5000e^{0.02t}$

When their populations are equal,

$\begin{array}{rcl}2000e^{0.05t} & = & 5000e^{0.02t}\\e^{0.05t} & = & 2.5e^{0.02t}\\0.05t & = & \ln2.5 + 0.02t\\0.05t & = & 0.9163 + 0.02t\\0.03t & = & 0.9163\\t& = & \dfrac{0.9163}{0.03}\\\\& = & \mathbf{30.54}\\\end{array}\\\text{The populations of species A and B will be the same in $\large \boxed{\textbf{30.54 yr}}$}$

The diagram below shows the population of Species A overtaking that of Species B in about 30.5 yr.

Please help! I need this to pass. If you are trying to get points please just chose a different question and don't mess with min

Given:

Radius of the cylinder = 2 cm

Height of the cylinder = 3 cm

To find:

The surface area of the cylinder.

Solution:

The surface area of a cylinder is:

$A=2\pi rh+2\pi r^2$

Where, r is the radius and h is the height of the cylinder.

Putting $r=2,h=3,\pi = 3.14$ , we get

$A=2(3.14)(2)(3)+2(3.14)(2)^2$

$A=37.68+25.12$

$A=62.8$

Therefore, the surface area of the cylinder is 62.8 square cm.
