Answer:
f(x) is an even if and only if f(-x) = f(x). f(x) is an odd if and only if f(-x) = -f(x). We have r(-θ) = r(θ). Therefore the graph of r(θ) is symmetric about the y-axis.

Answer:
y=14n^2-42n+9
Step-by-step explanation:
m=7n-3
y=m^2
then...
y=(7n-3)^2
y=14n^2-42n+9
Answer:
$25
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
putting time into years for simplicity,
12 months ÷ 12 months/year = 1 years,
then, solving our equation
I = 500 × 0.05 × 1 = 25
I = $ 25.00
The simple interest accumulated
on a principal of $ 500.00
at a rate of 5% per year
for 1 years (12 months) is $ 25.00.

Answer:
∠ CDB = 43°
Step-by-step explanation:
Angles subtended at the circumference by the same arc are congruent.
The arc CB subtends both ∠ CAB and ∠ CDB , thus
∠ CDB = ∠ CAB = 43°
