Let's check your answer:

\begin{gathered} f(x)=3(6^{\text{ -x}}) \\ f(1)=3(6^{\text{ -1}})=3(\frac{1}{6})=\frac{3}{6}=\frac{1}{2} \\  \\ f(2)=3(6^{\text{ -2}})=3(\frac{1}{6^2})=3(\frac{1}{36})\text{ = }\frac{1}{12} \\  \\ f(3)=3(6^{\text{ -3}})=3(\frac{1}{6^3})=3(\frac{1}{216})=\frac{3}{216}=\frac{1}{72} \\  \end{gathered}

Your answer is correct.

A wood frame costs $1.50. Use a property to write an equivalent expression for the cost of a wood frame.
podryga [215]
Let the width of the frame = x
Let the cost of a linear foot of the frame = y
Let the inside dimension of the length of the frame = a
Let the inside dimension of the width of the frame = b.

The total length of the frame = 2*a + 4x
The total width of the frame = 2b

The total amount of the frame in feet is (2a + 4x + 2b)*y = Cost

What is the height of the tv and is it square inches or inches ??
fiasKO [112]
To find the height of the TV you first need to realize that the question is giving you dimensions for a triangle. 

Every triangle has a hypotenuse and two sides. To find the hypotenuse you square both sides, add them, and then square root. So to find one of the sides you get the hypotenuse, square it, and subtract the square length of the given side. 

The equation is 25^2-20^2.
Which if simplified is 625-400, the then solution is going to be 225. 
You next will square root 225, 225^(1/2). Which your answer should be 15 inches for the missing side length.

anzhelika [568]

Answer:

1 gallon every 16 minutes

Step-by-step explanation:

If after 32 minutes the container has 6 gallons left that means it has lost 2 gallons of water. So we now divide the 32 minutes by the 2 gallons of water to get that 1 gallon of water leaks every 16 minutes.
