Answer:
It opens to the right and the vertex is at (0, -8).
The axis of symmetry is y = -8.
Step-by-step explanation:
The vertex is halfway between the directrix and the focus.
The focus is to the right of the directrix so the curve will open towards the right. The axis of symmetry is the line y = -8.
Answer:1) 1/12 2)21/5 3) 9/25.
Step-by-step explanation:
5x1/12x5 is 5/60, which is 1/12. 4 2/3 is 14/3. 14x9/3x10 is 126/30, or 21/5. 36 percent is 36/100. Divide by 2. 18/50. Divide by two again, 9/25.
Answer:
➢ 1. Draw base AB of 6cm then construct 90° on A then take a compass and open it 4cm then from point A cut the arc on that 90° and name that point C. Join B to C triangle ABC will be the required triangle.

Answer:
volume of the hemisphere ≈1577.5 cm³
Step-by-step explanation:
To find the formula for calculating the volume of a hemisphere, we will follow the steps below:
write the formula for calculating the volume of a hemisphere.
volume of a hemisphere = volume of a sphere ÷2
=
πr³ ÷ 2
=
πr³
WHERE r is the radius
from the question given, radius= 9.2 cm
π is a constant and is ≈ 3.14
we can now proceed to insert the values into the equation
volume of a hemisphere =
πr³
=
× 3.14 ×9.2³
=
× 3.14 ×753.571
≈1577.5 cm³ to the nearest tenth of cubic centimeter
volume of the hemisphere ≈1577.5 cm³
