(a)
To find: the distance the hummingbird does feed.
(a)
Answer to Problem 31E
The hummingbird feeds at distance of o ft, 4ft, and 7 ft.
Explanation of Solution
Given information:
A hummingbird flies while feeding can be modeled by the function,
Where
Calculation:
To determine the distance at which the hummingbird feeds, substitute
Therefore, the hummingbird feeds at distance of o ft, 4ft, and 7 ft.
(b)
To write: a function to model the path of the second hummingbird.
(b)
Answer to Problem 31E
Model for the path of second hummingbird is
Explanation of Solution
Given information:
A hummingbird flies while feeding can be modeled by the function,
Where
A second hummingbird feeds 2 meters farther away than the first hummingbird and flies twice as high.
Calculation:
The second humming bird’s path can be modeled by translating the first humming bird’s model 2 unit’s right followed by a vertical stretch by a factor of 2.
Therefore, model for the path of second hummingbird is

Remember that: A matrix is in row echelon form if Any row that consists only of zeros is at the bottom of the matrix. The first non-zero entry in each other row is 1. This entry is called aleading 1. The leading 1 of each row, after the first row, lies to the right of the leading 1 of the previous row.arrow_forwardPRIMERA EVALUACIÓN SUMATIVA 10.
