Westkost [7]

Answer:

x=-4.992 and x=-0.434

Step-by-step explanation:

we have

$\frac{\sqrt{3x+15}}{5}=2^{x}$

we can divide the equation above into two equations

$y=\frac{\sqrt{3x+15}}{5}$ ----> equation A

$y=2^{x}$ ----> equation B

Solve by graphing

The solutions of the system are the x-coordinates of the intersection points both graphs

using a graphing tool

The solutions are x=-4.992 and x=-0.434

lidiya [134]

Answer:

Option A

Step-by-step explanation:

Land area of Charlotte, NC = $3\times 10^2$ square miles

Scale to be used,

1 square miles = $6.4\times 10^2$ square acres

By this scale,

$3\times 10^2$ square miles = $(6.4\times 10^2)\times(3.2\times 10^2)$ square acres

= $(6.4\times 3)\times 10^{2+2}$

= $19.2\times 10^4$ square acres

= $1.92\times 10^5$ square acres

Therefore, Option A will be the correct option.
