Answer:
8: 190 yd , 9: 30 m, 10: 92 ft
Step-by-step explanation:
for 8, you can spit it up pretty simply. find 10x18 which is 180 and then 5x2 which is 10 so 8 is 190.
for 9, 2x8=18 for the top portion and for the sides 3x2=6, so twelve. Combined its 30m.
for 10, 10x8=80, then 6x2=12. so 92 ft combined.

Answer:
Step-by-step explanation:
A mirror with a parabolic cross section is used to collect sunlight on a pipe located at the focus of the mirror.
The pipe is located 7 inches from the vertex of the mirror.
The parabola is open upwards . the vertex of the parabola is (0,0)
and pipe is located 7 inches from the vertex (0,0)
7 inches is the focus of the mirror
The distance between the vertex and the focus = 7
Since parabola is upwards and vertex is (0,0) we use formula
Where p is the distance between the vertex and focus
p = 7 we know
Now isolate y by dividing 28 on both sides
