Graphing Exponential Functions In Exercise, sketch the graph of the function.
denis23 [38]

Answer:

The graph of the function f(x) = (1/2)^2x + 4 is attached as image below.

Analysis:

We have two intersection points in the graph

The function f(x) = (1/2)^2x + 4  intersects the y-axis at points (0,4)

The function f(x) = (1/2)^2x + 4  intersects the x-axis at points (-16,0)

f(x) is positive for x>-`16

f(x) is negative for x<-`16

The building of the Blue Museum of Barcelona is triangular. Each side of the building is 180 m. How far do we have to travel to
Sever21 [200]

Answer:

540 m

Step-by-step explanation:

The building of the Blue Museum of Barcelona is triangular and each side of the building is 180 m.

This means the building is shaped as an equilateral triangle.

We need to find the total distance traveled if we go round the building, that is, its perimeter.

The perimeter of an equilateral triangle is given as:

P = 3L

where L = length of the side of the building = 180 m

The total distance traveled if we go round the building will be:

P = 3 * 180 = 540 m

We would need to go 540 m to travel around the building completely.
