We have that
2x² + 9y²<span> = 18------> divided by 18
so
</span>2x² /18+ 9y²/18 = 18/18------> x/9² + y²/2 = 1
Part a)
the equation of the ellipse if of the form
(x-h)²/a²+(y-k)²/b²=1
where (h,k) is the center
in this problem
(h,k) is (0,0) ------> is the origin
a²=9------> a=3
b²=2-----> b=√2
Part b)
vertices are
(h+a,k) and (h-a,k)
(0+3,0)-----> (3,0)
(0-3,0)----> (-3,0)
Part c)
foci are
(h+c.k) and (h-c, k)
where
c²=a²-b²-----> c²=9-2-----> c²=7-----> c=√7
the foci are
(0+√7, 0)-----> (√7,0)
(0-√7,0)------> (-√7,0)
Answer:
N/4
Step-by-step explanation:
quotient is the same as division
since we don't know what the number is we use n as the variable
so n/4
Hope this helps
Answer:
Solve the system of equations by graphing, elimination or
subod
Step-by-step explanation:
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
we know that
A composite function is a function that depends on another function. A composite function is created when one function is substituted into another function
we have
Part 1) Determine f(g(x))
To find f(g(x)) substitute the function g(x) as the variable in function f(x)
so
Part 2) Determine g(f(x))
To find g(f(x)) substitute the function f(x) as the variable in function g(x)
so
For x=5
