Answer:
314 cm ^ 2
Step-by-step explanation:
First do, 3.14 x 20 ^ 2
3.14 x 20 ^ 2 = 1,256
Then do, 1,256/4
1,256/4 = 314
Why 4?
This part of the circle is 1/4 of the entire circle.
What does ^ mean?
It's just a way to say to the power of on a computer.
Hope this helps! :)
Step-by-step explanation:
it looks like this is a regular (right) triangular prism with 3 equal side areas and one bottom area.
the surface area of the pyramid is the sum of all 4 of these areas.
all these areas are triangles.
the area of a triangle is
baseline × height / 2
in our case
1 side area is 6×8.2/2 = 3×8.2 = 24.6 yd²
all 3 side areas together are 24.6×3 = 73.8 yd²
the bottom triangle is
6×5.2/2 = 3×5.2 = 15.6 yd²
so, the total surface area is
73.8 + 15.6 = 89.4 yd²
Answer: x=3
Step-by-step explanation:
To find the zeros, you want to first factor the expression.
x³+x²-36
(x-3)(x²+4x+12)
Now that we have found the factors, we set each to 0.
x-3=0
x=3
Since x²+4x+12 cannot be factored, we can forget about this part.
Therefore, the zeros are x=3. You can check this by plugging the expression into a graphing calculator to see the zeros.
I hope it helps you get it right
TABLE D does NOT represent a linear function
<h2>
Explanation:</h2>
The Table is shown below. Each table is a relationship between two variables, namely x and y. By plotting each table in a graphing tool we get:
TABLE A, FIRST FIGURE:
It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

TABLE C, SECOND FIGURE:
It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

TABLE C, THIRD FIGURE:
It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

TABLE D, FOURTH FIGURE:
It is not a linear function. It is likely this is a parabola that opens downward.
