A population of 400 beetles grows by 5% each week. How can the beetle population be determined after a number of weeks, w?
Helga [31]
For this case we have an equation of the form:
 f (w) = A * (b) ^ w
 Where,
 A: initial amount
 b: growth rate
 w: number of weeks
 Substituting values we have:
 f (w) = 400 * (1.05) ^ w
 Answer:
 the beetle population can be determined after a number of weeks, w, with the following function:
 
f (w) = 400 * (1.05) ^ w

A company that manufactures toy trains is making a new boxcar. To fit on the track, the smallest dimension of the toy boxcar mus
pochemuha

Answer:

Length = 12 inches, height = 3 inches

Step-by-step explanation:

First, you have to set up a proportion. 2/7, x/42.

Then, you cross multiply and get the setup of 84=7x

Finally, you divide 84 by 7 and get 12.

12 is the length, and there is no other answer that has 12 in the height. You could just do the same proportion to get 3, though.

How do I solve the following system of equations? <br>-5x-3y=7<br>-3x-4y=2​
garri49 [273]

Answer:

(-2, 1)

Step-by-step explanation:

Systems of equations can be solved using different methods.  For this set of systems, you can multiply each equation by a factor in order to eliminate a variable and solve for the other variable:

-3(-5x - 3y = 7)  or 15x + 9y = -21

5(-3x - 4y = 2)  or <u>-15x -20y = 10</u>

                                    -11y = -11

                                        y = 1

Solve for x:  -5x - 3 = 7

Add 3 to both sides:  -5x -3 + 3 = 7 + 3 or -5x = 10

Solve for x: x = -2
