Answer:
The equation of ellipse is 
.
Step-by-step explanation:
The center of ellipse is origin because the ellipse has foci at (4, 0) and (-4, 0); y-intercepts (0, 3) and (0, -3).
The general equation of an ellipse is
Where, a is major axis and b is minor.
The y-intercepts are (0, 3) and (0, -3). So, the value of b is 3.
The foci of ellipse is 
.The relation between foci and major, minor axis is
The equation of ellipse is

Answer:
<h2>1529.4 m³</h2>
Step-by-step explanation:
Volume of a pyramid can be found by using the formula
a is the area of the base
h is the height
Since the base is a square we have
We have the final answer as
<h3>1529.4 m³</h3>
Hope this helps you
Answer:
15 ft
Step-by-step explanation:
Hi, the illustration for the problem is a right triangle with:
hypotenuse (C)= the length of the ladder = L
horizontal side(A) = distance from bottom of the ladder to the building = L - 6
vertical side(B) = distance from the top of the ladder to the bottom of the building = L - 3
So, we can use Pythagoras formula:
A2 +B2= C2
(L – 6 )² + (L-3)² = L²
L²-12L+36+L²-6L+9 =L²
L2 -18L+45 =0
APPLYING QUADRATIC FORMULA WE OBTAIN:
L =15 OR L=3
If L=3
Vertical side = L-3 = 0 (Length can´t be 0)
So L=15
So one date can be berween 12_6, so twelve or six hours you multaply it by another witch if the first date was 12+12so what does that = and then th t would be
the second date so it could be nother 12+12 day and night so you count between the hours hoped I helped plz mark as brainy thx
