pogonyaev
The graph of f(x) = (0.5)^x is replaced by the graph of g(x) = (0.5)^x − k. If g(x) is obtained by shifting f(x) down by 2 units, the value of k is 2 because g(x)=(.5)x-2. g(x) is f(x) without the "shift" and it said the shift was 2 units, so k is 2

Pamela deposits $4,000 in an account that earns interest at 5% APR compounded weekly. What is her ending balance after 2 years?
Triss [41]
The answer is $4419.76

A = P (1 + r/n)^nt

Therefore,

A = 4000 (1 + 0.05/52)^52 x 2
A = 4000 (1.00096)^104
A = 4000 (1.1049)
A= 4419.76

Hope that helps!

Can someone please help me solve this? thank you!:)
Nataliya [291]

First, we need to set up our two equations. For the picture of this scenario, there is one length (L) and two widths (W) because the beach removes one of the lengths. We will have a perimeter equation and an area equation.

P = L + 2W

A = L * W

Now that we have our equations, we need to plug in what we know, which is the 40m of rope.

40 = L + 2W

A = L * W

Then, we need to solve for one of the variables in the perimeter equation. I will solve for L.

L = 40 - 2W

Now, we can substitute the value for L into L in the area equation and get a quadratic equation.

A = W(40 - 2W)

A = -2W^2 - 40W

The maximum area will occur where the derivative equals 0, or at the absolute value of the x-value of the vertex of the parabola.

V = -b/2a

V = 40/2(2) = 40/4 = 10

Derivative:

-4w - 40 = 0

-4w = 40

w = |-10| = 10

To find the other dimension, use the perimeter equation.

40 = L + 2(10)

40 = L + 20

L = 20m

Therefore, the dimensions of the area are 10m by 20m.

Hope this helps!
