Answer:
the directrix and focus the axis of symmetry (goes through the focus, at right angles to the directrix) the vertex (where the parabola makes its sharpest turn) is halfway between the focus and directrix.
Step-by-step explanation:
C=2pr
r=C/(2p) and we are given C=85 so
r=85/(2p) meters
r≈13.53 meters (to nearest one-hundredth of a meter)
The answer to your question is 3.666
Answer:
Area= 70x^3y^2
Perimeter = 20x^2 + 14 xy^2
Step-by-step explanation:
Area is just multiplying the length and width, I multiplied the constants first which gets us 70 then multiplied the variables, they combine however only the x's can be multiplied to each other which results in 70x^3y^2 . The perimeter you just multiply the length by two and the width by two, they are separate because the variables when added to each other do not combine.
