Answer:
B is your answer
Step-by-step explanation:
the standard form for a horizontal ellipse is
X^2/a^2 + y^2/b^2 = 1
Substitute 54 for b and and use (8,18) as the
point to find a
x=8
y=18
8^2/a^2 + 18^2/54^2 =1
64/a^2 + 324/2916 = 1
324/2916 reduces to 1/9
64/a^2 + 1/9 = 1
64/a^2= 1-1/9
64/a^2 = 8/9
64*9/8 = a^2
576/8 = 72
A^2 = 72
A = square root(72) = 8.485
So formula
would be x^2/72 + y^2/2916 =1
3(9)=27
27+4Y=43
subtract 27 from both sides
4Y=16
devide both sides by 4
Y=4
P = 2 × 4in + 2 × 1in = 8in + 2in = 10in
<h2><u>
P = 10 in</u></h2>
Answer:
The y-intercept is (0, 3)
<em>they typed the equation wrong so that's why it's (0, 3)</em>
