Step-by-step explanation:
Given
See attachment for the given data
Required
Which length is closest to 4.2lb
The given data is a linear dataset.
So, we start by calculating the slope (m)
Pick any two corresponding points from the table
So, we have:
So:
The linear equation is then calculated using:
This gives:
Open bracket
To get the length closest to 4.2lb,
we set
Then solve for x
So, we have:
Collect like terms
Solve for x
ΔQVS is similar to ΔRTS
.
<u>Solve x:</u>
6x = 80
x = 40/3
x = 13 1/3
.
Answer: x = 13 1/3
