The projected population for 2015 should be 47,600. 32,800-18,000=14,800 so 14,800 times 3 is 47,600. Hope this helped :)

A square garden has an area of 1600 feet length of each side
dimaraw [331]
* <em>L is the Length</em><em /> <em>and A is the Area
</em><em />
L * L = A
L * L = 1600
L^2 = 1600
√L^2 = √1600
L = 40 feet

Answer: The length of each side is 40 feet.

Btw: <em />this was your question "<em>A square garden has an area of 1600 feet length of each side"</em>

When it should be . . .

<em>"A square garden has an area of 1600 feet squared length of each side"</em>

Solve the system by substitution.<br> y = -7x. y = -5x + 10​
ohaa [14]

Answer: (-5,35)

Step-by-step explanation:

-7x=-5x+10

Get x on one side by adding 5x

-2x=10

Simplify by dividing by -2

X=-5

Substitute into y=-7x

Y=-7(-5)

Simplify

Y=35

2. The number of atoms of a particular chemical element is modelled by
____ [38]

9514 1404 393

Answer:

  a) 600

  b) see below

  c) 1.26 hours

Step-by-step explanation:

a) The value of y when x=0 is the coefficient of the exponential term:

  y = 600·3^(-0) = 600·1 = 600

There were 600 atoms to start.

__

b) see attached for a graph

__

c) The graph shows 150 atoms at t = 1.26, about 1.26 hours after the start of time counting.

If you want to find that value algebraically, substitute for y and solve for x. Logarithms are involved.

  150 = 600·3^(-x)

  150/600 = 3^(-x)

  log(1/4) = -x·log(3)

  x = -log(1/4)/log(3) = log(4)/log(3) ≈ 1.2618595

After about 1.26 hours, there were 150 atoms.
