The drawing of the lake has the scale of 1 centimeter to 80 meters.
Now, the actual width of the scale is of 1000 meters.
To find out the width of the lake on the drawing we need to convert the actual length as per the scale drawing.
Since we know that in the given scale drawing we have,
1 centimeter = 80 meters
Or we can say that
80 meters = 1 centimeter
1 meter =
meter
Now, 1000 meters should be equivalent to
centimeters.
Therefore, the width of the lake on the scale drawing is 12.5 centimeters.
Answer:
See attachment
Step-by-step explanation:
The given equation is:

We divide through by 3 to obtain;

This is rewritten as:

This is the equation of a circle centered at the origin with radius 5 units.
Answer:
4
Step-by-step explanation:
REMEMBER: Y is = f(x).
So the function is equal to the y value.
When x is 3, y is (if you go up the line intersects at) 4.
The value of he function when x = 3 is 4.
First compute the perimeter of the first two windows: (3.4+5.2)*2=17.2
The perimeter of the four other windows: (3.6+4.8)*2=16.8
The total number of feet needed for the first two windows:
17.2*2 = 34.4 feet
The total number of feet needed for the four windows:
16.8*4 = 67.2 feet
The total number of feet needed is then: 34.4 + 67.2 = 101.6 feet.
Functions are used to represent graphs, and vice versa.
The function represented by the graph is 
The graph (see attachment) is an absolute value graph.
An absolute value graph is represented as:

Where

The vertex is the minimum or the maximum point on the graph.
So, we have:

The function becomes

The function also passes through the point (-1,0).
So, we have:


Remove the absolute bracket

Subtract 3 from both sides

Divide both sides by 3

Substitute -1 for (a) in 

Hence, the function represented by the graph is
