Answer:
a. 12.8 cm b. 3.125
Step-by-step explanation:
To find any scale drawing use a proportion with one unit of values on the top and the other on the bottom. For example 8cm/5km = x/8km. So you would multiply 8 cm and 8 km and then divide by 5 to get 12.8 cm. For the second question plug in 5m in the numerator and solve for its denominator.
The answer is: The first triangle. The reasons are shown below:
1. All the triangles are rigth triangles, because they have an angle of 90°. So, let's calculate the others angles of the first one:
Tan(α)^-1= opposite leg/adjacent leg
Opposite leg=5
Adjacent leg=5√3
Tan(α)^-1= 5/5√3
Tan(α)^-1=30°
2. Let's calculate the other angle:
Tan(α)^-1= opposite leg/adjacent leg
Now, the opposite leg will be 5√3 and the adjacent leg will be 5. Then:
Tan(α)^-1= 5√3/5
Tan(α)^-1=60°
As you can see, the angles of first triangle are: 30°,60° and 90°.
Answer:
Step-by-step explanation: A GENERAL NOTE: VERTICAL STRETCHES AND COMPRESSIONS
Given a function a new function where is a constant, is a vertical stretch or vertical compression of the function

, then there will be combination of a vertical stretch or compression with a vertical reflection.HOW TO: GIVEN A FUNCTION, GRAPH ITS VERTICAL STRETCH.Identify the value of Multiply all range values by the graph is stretched by a factor of the graph is compressed by a factor of
, the graph is either stretched or compressed and also reflected about the
EXAMPLE: GRAPHING A VERTICAL STRETCHmodels the number of fruit flies in a population over time, and is graphed below.A scientist is comparing this population to another population, whose growth follows the same pattern, but is twice as large. Sketch a graph of this population.Graph to represent the growth of the population of fruit flies.
