Answer:
35triangles
Step-by-step explanation:
Given
Total distinct points = 7
If we are to form triangles using the dots,
Total points in a triangle = 3
Using the combination rule;
number of triangles formed = 7C3
7C3 = 7!/(7-3)!3!
7C3 = 7!/4!3!
7C3 = 7*6*5*4!/4!3!
7C3 = 7*6*5/6
7C3 = 7*5
7C3 = 35
Hence the amount of triangles that can be formed is 35triangles
Answer:
a = 157.7536pi
Step-by-step explanation:
area = pi*circumference²
a = pi*12.56² = 157.7536*pi
however, if pi just equals 3.14:
probably around 495.346304
Answer:
Step-by-step explanation:
Answer:
(a) and (f)
Step-by-step explanation:
Given

See attachment for table and options
First, we calculate the slope of the table

Using:


So, we have:



The equation is then calculated using:

This gives:



So, we have:
--- The given equation
and
--- The equation of the table
An equation is represented as:

Where:
m = slope or rate of change
b = y intercept
So, for the given equation: 
Rate of change = 5
y intercept = 12
For the table: 
Rate of change = 12
y intercept = 5
In conclusion:
(a)
has the greater rate of change:
and
(f)
has the greater y intercept
