Answer:
48x^2-48x+12
Step-by-step explanation:
3(area of square)
3(w^2)
3((4x-2)^2)
3(16x^2-16x+4)
48x^2-48x+12
False, the side across from the right angle is called the hypotenuse
Answer: The ice image, bottom left.
Step-by-step explanation:
The albedo values give information about the proportion of radiation that a given object surfaces, for example, if an object has an albedo value of 0.2, this means that the object reflects 0.2*100% = 20% of the radiation.
You usually can see that darker objects have a smaller albedo value, while clearer objects have a bigger albedo value, meaning that as clearer is the color, usually it reflects a bigger proportion of the radiation.
Here we have that the bigger albedo value is in the ice ( 0.55), so the correct image is the ice image, at the bottom left.
for number 5, you take the area of the area of the fountain, which is pi * radius squared. this is equivalent to 3.14 * 4^2. then to simplify I made it 3.14 times 16 and then got the answer of 50.24. Then you take the area of the fountain plus the path, which makes the diameter 9.5 divide that by 2 to get the radius, which is 4.75. pi * 4.75^2 is about 70.85. then you subtract the two(70.85-50.24) to get 20.61. since its 10 dollars per square meter, you multiply 20.61 by 10 to get 206.10 dollars. That is your answer.
