Answer:
The enlarged picture will have a width of 35.8 cm
Step-by-step explanation:
We can solve this question by proportions, using rule of three.
When the length is of 15 centimeters, the width will be of 14.5 centimeters. What is the width when the length is 37 centimeters?
15 cm - 14.5 cm
37 cm - x
Applying cross multiplication
![15x = 14.5*37](https://tex.z-dn.net/?f=15x%20%3D%2014.5%2A37)
![x = \frac{14.5*37}{15}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B14.5%2A37%7D%7B15%7D)
![x = 35.8](https://tex.z-dn.net/?f=x%20%3D%2035.8)
The enlarged picture will have a width of 35.8 cm
Answer:
an = 10 + (-2)(n-1)
Step-by-step explanation:
We are given from the sequence first term, a1 = 10
common difference, d = a2 - a1
Where; a2 = second term = 8
d = 8 - 10 = -2
From the formula, an = a1 + d(n - 1),
We substitute the value of a1 and d
therefore, an = 10 + (-2)(n - 1)
