Answer: n^3/m^2
Step-by-step explanation:
first, i expressed it with a positive exponent.
1/m^2 x n^3
then, i calculated it from there.
n^3/m^2
Answer: $20$20 is $25\%$25% of $80$80.
Step-by-step explanation:
25
2 1/2 gallons of paint.
If 1/2 gallon covers 1/5 of the wall, multiply 1/2 gallon by 5 to find how much is needed to cover 5/5, or the entire wall. You get 5/2. Now, simplify. 5/2 = 2 1/2 gallons of paint.
Solution:
Any point (x,y) on the parabola is equidistant from the directrix and the focus:
Thus,
√[(x-0)²+(y-(-2))²]=y-(6)
√(x²+(y+2)²)=y-6
x²+(y+2)²=(y-6)²
x²+y²+4y+4=y²-12y+36
x²=-16y+32
x²=16(2-y)
