Answer:
V≈169.65
Step-by-step explanation:
-----------------------------------------
Find area of the base
-----------------------------------------
6 x 6 = 36cm²
-----------------------------------------
Find the area of one triangle
-----------------------------------------
1/2 x 6 x 8 = 24 cm²
-----------------------------------------
Find the area of 4 triangles
-----------------------------------------
24 x 4 = 96cm²
-----------------------------------------
Total Surface Area
-----------------------------------------
96 + 36 = 132cm²
-----------------------------------------
Answer: 132 cm²
-----------------------------------------
(-3x+3y=-9)-(-3x+y=7)
-3x+3x+3y-y=-9-7
2y=-16
y=-8, making -3x+3y=-9 become:
-3x+3(-8)=-9
-3x-24=-9
-3x=15
x=-5
So the solution to this system of equations is the point (-5, -8)
Answer:
A. There is a focus at (-9, 1).
D. There is a directrix at x = -5.8.
F. There is a directrix at x = -2.2.
