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

Perimeter P = 2L + 2W
b. P = 2*1010 + 2*1818 = 2020 + 3636 = 5656 inches
c. Area A = WL
d Area = 1010*1818 = 1836180 in^2
45m 6m^5 usually helps to list the factors of each number first,
1x45=453x15=455x9=45
1x6=62x3=6
so the biggest number that fits into both would be 3, and the biggest amount you can take of any variable would be the amount of that lowest variable. when given an "m" and "m^5", you can only take out one "m", because when m÷m=1, that means you can't take any more "m's" out. if it were m^2 and m^5 you would take out m^2 :)
so your final answer would be"3m" and if you were taking it out of an equation (if you had 45m+/-6m^6)would look like 3m(15+/-2m^4
Answer:
15 km/h
Step-by-step explanation:
To find the speed, divide the total number of kilometers by the total number of hours:
Find the total number of hours:
32 + 13
= 45
Divide this by 3:
45/3
= 15
So, the average speed was 15 km/h
