Answer:

f(e - 9) = 8e - 67

Step-by-step explanation:

To evaluate f(e - 9) substitute x = e - 9 into f(x)

f(e - 9) = 8(e - 9) + 5 = 8e - 72 + 5 = 8e - 67

The given polygons are similar

Step-by-step explanation:

By observing the given diagrams, we can see that the respective angles are congruent.

Two shapes are said to be similar if they have same shapes or one shape is created by uniformly increasing or decreasing the side of other.

For this purpose we find the scale factor of greater to smaller image, if the scale factor is same for each side then the two shapes are similar

So,

The scale factor is:

$\frac{EF}{AB} = \frac{3}{1} = 3\\\\\frac{FG}{BC} = \frac{9}{3} = 3\\\\\frac{GH}{CD} = \frac{15}{5} = 3\\\\\frac{EH}{AD} = \frac{21}{7} = 3$

We can see that the scale factor is same for all sides.

Hence,

The given polygons are similar

An archery target consists of a circular bull's-eye with radius x, surrounded by four rings with width y. What is the area of th

amid [387]

<span>given:
bull's eye radius= x
width of surrounding rings=y

solution:
Radius of the circle=x+4y
Area of the outermost ring=Area of the circle-Area of the penultimate ring =Ď€(x+4y)^2-Ď€(x+3y)^2
=Ď€(x^2+8xy+16y^2-x^2-9y^2-6xy)
=Ď€(2xy+7y^2)
hence the area of the outermost ring in terms of x and y is Ď€(2xy+7y^2).</span>
