X and y are the half length of the largest and smallest diameter of the ellipse.
Area of the Ellipse , a = πxy
To find: Equivalent Equation for y.
Consider,
a = πxy
πxy = a
(πx)y = a
transpose πx to RHS,
y = a ÷ ( πx )
Hope this helps!
Answer:
96 square inches.
Step-by-step explanation:
From given picture we see that
BC=8 in
AD=10 in
Given that
AD=AB
Then AB=10 in
Apply Pythagorean theorem in triangle ABC to find AC






take square root

Then area of triangle ABC 

There are total 4 congruent triangles.
Then total area of the given figure = 4(24)=96 square inches.
Answer:
1. y=1x-2
We can't see the rest
Step-by-step explanation:
Z = 180 - 69
z = 111
x = 180 - (111+23)
x = 180 - 134
x = 46
y = 23
w = 180 -(69 + 23)
w = 180 - 92
w = 88
Answer:x=2
Step-by-step explanation:
-8x+10-6=-12
Collect like terms
-8x+4=-12
-8x=-12-4
-8x=-16
x=2
