Answer:
1794 square inches
Step-by-step explanation:
L X W = A
Length X Width = Area
46 - 7 = 39
39 x 46 = 1794
Both rectangles could be divided into 36 parts
Parabola
remember that
parabola equation is
4p(y-k) =(x-h)^2 for a verticl parabola
p=distance from vertex to focus and from vertex to directix
solve for p, k, h
y=0.6x^2
4p(y-0)=(x-0)^2
divide both sides by 4p
(y-0)=1/4p times (x-0)^2
y=0.6x^2
1/(4p)=0.6
find p
multiply 4p
1=2.4p
divide 2.4
1/2.4=p
h=0,k=0
vertex=0,0
opens up so go up to find focus
(0,0)
0+1/2.4=1/2.4
focus is at (0,1/2.4)
Answer:
4 dollars per pound
Step-by-step explanation:
24/6 = 4
let's firstly convert the mixed fractions to improper fractions and then add up all four days.
