We know that
Limacons are in the form
r=a(+-)b*sin (theta) or r=a(+-)b*cos (theta)
in this problem
r=a(+-)b*sin (theta)
so
is symmetric to y axis
a=1/2
b=1/2
a/b=1---------> Cardioid (hearth shaped)
see the attached figure
the answer is the option

Answer:
87.5 ml tube of toothpaste slightly offers the better value of money.
Step-by-step explanation:
In order to know the better value of money, we need to find the volume of each toothpaste for 1p.
For first tube of toothpaste:
87.5 ml costs 49p
Therefore, for 1 p = 87.5/49 = 1.78571429 = 1.8 ml
For second tube of toothpaste:
125 ml costs 72 p
Therefore, for 1 p = 125/72 = 1.73611111 = 1.7 ml
Since, 1.8 ml > 1.7 ml
So, 87.5 ml tube of toothpaste slightly offers the better value of money.
Answer:
Functions can be represented using equations and graphs
The key features are (1) both f(x) and g(x) include domain values of [3, ∞) and range values of (0, ∞), and both functions are positive for the entire domain.
How to determine the key features
The functions are given as:
Using a graphing calculator:
The domain of g(x) is
The range of g(x) is
The domain of f(x) is
The range of f(x) is
Both functions have positive values for their domains
By comparing the above highlights, the true statement between functions g(x) and f(x) is option (1)
