Answer:
A
Step-by-step explanation:
If y = 0.5 x 3^x I will use any 2 points from the table to replace x and y.
Let's use (2 , 4.5) and (3 , 13.5).
0.5 x 3^2 = 0.5 x 9 = 4.5
x = 2 y = 4.5
0.5 x 3^3 = 0.5 x 27 = 13.5
x = 3 y = 13.5
13·[18÷6]
13·3
39
the answer is 39
note that first we start with the problem that is the most inside of the operation
Its solved already??any more questions just ask me:)
Answer:
46.37 square units
Step-by-step explanation:
If the right triangle is revolved the figure shown about the y-axis completely, the figure will be formed as a cone. As you can see in my attached photo.
So, the radius of the cone is : 2 units
the slant height is: = (use pytagon theory)
Hence, the total surface area of the resulting figure
SA = π * the radius * the slant height + π*
= 3.14*2* + 3.14*2*2
= 33.81 + 12.56
=46.37 square units
