How do i solve for this?

Answer:

Step-by-step explanation:

So you know the coords for the angle which is (1, 4).

Another coord might be (2, 5) or (0,3)

So we can find the slope

rise/run=1/1

so m=1

Sub in coords like (1,4) to find y-int

y=mx+b

4=1(1)+b

b=3

Thus y=x+3

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