Answer:
Step-by-step explanation:
The directrix of the parabola is the horizontal line with the eqaution 
The focus of the parabola is at point (-4,10), than the axis of symmetry of the parabola is the perpendicular line to the directrix passing through the focus. Its equation is 
The distance between the directrix and the focus is 
so 
and the vertex is at point 
Parabola goes in positive y-direction, hence its equation is
where 
is the vertex, so the equation of this parabola is
Answer:
I do not know, but I do know the formula.
The formula is: 12pl+B where p represents the perimeter of the base, l the slant height and B the area of the base.
Answer:
11.9
Step-by-step explanation:
The tenth place is the first decimal. You round down from 1-4 and up from 5-9, so round up.
11.9
Answer:
9.64ft
Step-by-step explanation:
Since the diagram tends to form...a right angled triangle....;
with PR = 17ft...,PQ = 14ft
then to calculate the length of QR
we use the pythagoras theorem...which is only applicable to right angled triangles
PR^2 = PQ^2 + QR^2
(17)^2 = (14)^2 + QR^2
where we make QR the subject of formula;
QR^2 = (17)^2 - (14)^2
QR = square root of( 289 - 196)
QR = square root of( 93)
;Therefore the length of QR = 9.64ft
