Answer:
Option c. Reflection across the x-axis and vertical stretch by a factor of 7
Step-by-step explanation:
If the graph of the function
represents the transformations made to the graph of
then, by definition:
If
then the graph is compressed vertically by a factor a.
If
then the graph is stretched vertically by a factor a.
If
then the graph is reflected on the x axis.
In this problem we have the function
and our paretn function is 
therefore it is true that
.
Therefore the graph of
is stretched vertically by a factor of 7 and is reflected on the x-axis
Finally the answer is Option c
Answer:
≈ 35.1 ft
Step-by-step explanation:
The model is a right triangle with ladder being the hypotenuse and the angle between the ground and the ladder is 70°
Using the cosine ratio, with l being the length of the ladder.
cos70° =
=
( multiply both sides by l )
l × cos70° = 12 ( divide both sides by cos70° )
l =
≈ 35.1 ( to the nearest tenth )
The ladder is approx 35.1 ft long
