ANSWER
It was given that the parabola has its focus at:
(-10,-7)
and directrix at:
x=16.
We need to determine the vertex of this parabola which is midway between the focus and the directrix.
Therefore the vertex will be at,
The equation of this parabola is of the form:
where p is the distance from the vertex to the focus.
Since the parabola opens towards the negative direction of the x-axis,
We substitute the vertex and the value for p to get;
Answer:
2W+2L=perimeter=74
Step-by-step explanation:
2W=74-2L
2(2W)+2(L/2)=76
substitute 74 - 2L for 2W in the last equation to solve for L. Put that value in the first equation to find W. Check by putting both values into the last equation.
The original statement is true only if:
- England is a country and Africa isn't
- Africa is a country and England isn't
- Neither of them are countries
Options a and d are equivalent:
and they both are true in the same cases as above.
Option c is also fine, because it is false only if both England and Africa are both countries, just like the original statement.
Option b, instead, is true only if neither of the two options are countries, so it doesn't cover the cases where only one of the two is a country.
Answer:
John earns $14.00 for two hours of work.
Step-by-step explanation:
you should know: in all means in total, so simply you add everything up.
answer:
1 + 2/4 + 3/4
- convert 1 to a fraction so its easier to add.
1 = 4/4 (must have the same denominator to add)
4/4 + 2/4 + 3/4
- add the numerators (top), NOT the denominators (bottom)
you get: 9/4 (this is an improper fraction, so you convert this into a mixed number)
9/4 = 2 1/4
FINAL ANSWER: (its a mixed number)
2 1/4
