The two functions are

y= f(x), ------------(1)

g(x)= f(x+2)---------(2)

⇒Consider a point (a,b) on the curve.It will satisfy (1).

b = f(a)

Now the point a is translated by 2 units right in horizontal direction and there is no vertical shift.

Coordinate of new point = (a+2,b)

Putting the value of new coordinate in equation (1), we get

b = f(a+2)

which gives equation (2), which is

g(x)= f(x+2)

Option (3) is correct,which is, the graph of g(x) is graph of f(x) translated 2 units right.

A circle with radius 5 has a sector with a central angle of 9/10 pi
Solnce55 [7]

Answer:

35.33

Step-by-step explanation:

The circle with radius 5 has a sector with a central angle of 9/10 pi.

The area of a sector is given as:

A_s = \frac{\alpha }{2\pi} * \pi r^2

where α = central angle of the sector in radians

r = radius of the circle

The area of the sector is therefore:

A_s = \frac{\frac{9 \pi}{10} }{2 \pi} * (3.14 * 5^2)\\ \\A_s = \frac{9}{20} * 78.5\\\\A_s = 35.33

The area of the sector is 35.33.
