The right answer is the very last one though the second one also contains x^3 but it's already shifted because +7
The others, by the way, are even functions :)
Answer:
where are the triangles????
The area of your figure is the sum of the areas of the base cuboid and the lateral area of the "tower."
The top and bottom areas of the base cuboid are (10 in)*(10 in) = 100 in^2, for a total of 2*100 in^2 = 200 in^2.
The lateral area of the base cuboid is its perimeter (4*10 in = 40 in) multiplied by its height (2 in), so is 80 in^2.
Likewise, the lateral area of the "tower" is the product of its perimeter (4*5 in = 20 in) and its height (8 in), so is 160 in^2.
The sum of all these is 200 in^2 +80 in^2 +160 in^2 = 440 in^2.
The 3rd selection is appropriate.
Answer:
The points form a equilateral triangle of side 5.78 units.
Step-by-step explanation:
The length of the sides of the triangle is calculated using the distance formula.
The distance between the points (x₁,y₁) and (x₂,y₂) is
Now,
AB =
BC =
CA =
The length of the sides of the triangle is 5.78. All the sides are equal in length. It is an equilateral triangle.
