Given :
D2/5 ( ABC ) = (A'B'C')
D5/3 ( A'B'C' ) = (A''B''C'')
So, the scale factor of dilation between ABC and A''B''C'' =
The answer is option 4) 2/3
Answer:
Step-by-step explanation:
Answer:
The average walking speed is 1.48 feet per second
Step-by-step explanation:
we have
where
r is average walking speed
p is the population in thousands
In this problem we have
----> because p in the equation is in thousands
substitute the value of p in the equation
using a calculator
Using the midpoint concept, it is found that the value of a is of a = 2.
<h3>What are the coordinates of the points?</h3>
Researching this problem on a search engine, the coordinates are given as follows:
<h3>What is the midpoint concept?</h3>
The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.
Hence the following system of equations can be built:
(b + 1 + 2a)/2 = 3.
b + 1 + 2a = 6.
b = 5 - 2a.
(a + 2 + 3b + 3)/2 = 5
a + 3b + 5 = 10
a + 3b = 5.
Since b = 5 - 2a, we have that:
a + 15 - 6a = 5.
5a = 10
a = 10/5
a = 2.
The value of a is of a = 2.
