<span>The name of the shape graphed by the function r ^ 2 = 9
cos (2 theta) is called the “<u>lemniscate</u>”. A lemniscate is a
plane curve with a feature shape which consists of two loops that meet at a
central point. The curve is also sometimes called as the lemniscate of
Bernoulli. </span>
Explanation:
The
period of coskθ is 2π/k. In this case, k = 2 therefore the
period is π.
r ^ 2 = 9 cos 2θ ≥0 → cos 2θ ≥0. So easily
one period can be chosen as θ ∈
[0, π] wherein cos 2θ ≥0.
As cos(2(−θ)) = cos2θ, the graph is symmetrical about the initial line.
Also,
as cos (2(pi-theta) = cos 2theta, the graph is symmetrical about the
vertical θ = π/2
A
Table for half period [0,π4/] is
adequate for the shape in Quarter1
Use symmetry for the other three quarters:
(r, θ) : (0,3)(3/√√2,π/8)(3√2/2,π/6)(0,π/4<span>)</span>
Answer:
finance charge refund is $91.53
Step-by-step explanation:
given data
finance charge F = $476
time t = 12 month
no of payment n = 5
to find out
finance charge refund
solution
we will apply here finance charge refund formula that is
finance charge refund = F × 
put here value we get
finance charge refund = 476 × 
finance charge refund = 476 × 
finance charge refund = 476 × 
finance charge refund = 476 × 0.1923
finance charge refund = 91.53
so finance charge refund is $91.53
Answer:
$21 is the answer
Step-by-step explanation:
Okay so all I did was find what number times 0.8=$16.80 which is $21.
Answer:
The horizontal asymptote is y=0
R - 4 x 8 is the expanded expression
