The average cost of online photos decreased
SCORPION-xisa [38]

Answer:

The average rate of change is -0.034 which means that the decrease is -0.034 in the cost of per print per year

Step-by-step explanation:

Given that

Price of print in 2002 = p1 =$0.50

Price of print in 2013 = p2 =$0.13

y1 = 2002

y2 = 2013

The rate of change is given by the formula:

r = \frac{decrease}{run}

Here decrease is the change in price and run is the difference in years.

Mathematically, it can be written as:

r = \frac{p_2-p_1}{y_2-y_1}

Putting the values

r =\frac{0.13-0.50}{2013-2002}\\r = \frac{-0.37}{11}\\r =-0.0336\\r = -0.034

Hence,

The average rate of change is -0.034 which means that the decrease is -0.034 in the cost of per print per year

Monica has a 24
melamori03 [73]

Answer:

The fraction of frame did Monica paint blue is \frac{3\sqrt{6}}{2}  

Step-by-step explanation:

Given as :

The area of square frame = A = 24 square inches

Monica paint \frac{3}{4} of one side of the frame blue

Let the measure of one side of frame = x

So, <u>From Area of square</u>

Area = side × side

Or, A = x × x

Or, x ² = 24

∴  x = \sqrt{24} = 2\sqrt{6}

So, Measure of each side = x = 2\sqrt{6}

Now, As Monica paint \frac{3}{4} of one side of the frame blue

So, The painted part = \frac{3}{4} ×  2\sqrt{6}

∴ The painted part = \frac{3}{2} × \sqrt{6}

I,e The fraction of painted blue = \frac{3\sqrt{6}}{2}

Hence, The fraction of frame did Monica paint blue is \frac{3\sqrt{6}}{2}  Answer
