Answer: A. 184.8ft2
Step-by-step explanation:
The pyramid is made up of four sides that are rectangular, each side has a height of 12.4ft and base length of 6ft.
The base area is a square of 6ft by 6ft.
For the sides, area of a triangle is 1/2 x base x height
= 1/2 x 6 x 12.4 = 37.2m2
For the four triangles = 4 x 37.2 = 148.8m2
For the square base, area is 6 x 6 = 36m2
Total surface area = 148.8 + 36 = 184.8ft2
The equation of parabola is 
Comparing with the vertex form of the parabola: 
Hence, the vertex of the parabola is given by (h,k) = (1, -2)
Now, vertex is the midpoint of the focus and the point on the directrix.
Distance, between vertex and focus is p and that of point on the directrix is p.
Now, let us find p
Thus, the focus is given by
And the directrix is given by
Since, a >0 hence, it is an upward parabola.
The graph is shown in the attached file.
The standard form for an equation is y=mx+b. You find the slope by using the formula of rise over run. This means that for problem 6 you first look to see if its positive or negative slope. The slope is positive if the line is going uphill and if its going downhill its negative. The slope would be negative for number 6 because it is going downhill. Then for the actualy slope you would start with rise. So you look at the point (0,1) and go up 3 until you hit the line of the other point and run over 2. So your slope would be -3/2.
Answer:
The radius is<em> 5</em>
Step-by-step explanation:
The radius is <em>half</em> the circumference. Therefore, <em>10 ÷ 2 = 5.</em>
Answer:
19
Step-by-step explanation:
(Assuming that each cube is 1 unit), the volume is 5 + 6 + 8 which equals 19
