Answer:

60.39 inches

Step-by-step explanation:

Given that:

A Pac-Man poster which is having three fourth of a circle and there are two sides.

Diameter of circle = 18 inches

Sides of Pac-Man poster = 9 inches

To find:

Perimeter of the Pac-Man poster.

Solution:

Perimeter of a figure is nothing but equal to the periphery i.e. the outer area of the circle/figure.

Perimeter of a circle is given by the formula:

Perimeter = 2\pi r

r is the radius of the circle.

Radius is half of perimeter.

r=\dfrac{18}{2} = 9\ inches

Perimeter of the Pac-Man poster = Perimeter of \frac{3}{4} circle + 2 sides

Perimeter of the Pac-Man poster = \frac{3}{4}\times 2\times \pi \times 9  + 9+9 = 42.39+28 = <em>60.39 inches</em>

7) Write an equation for the tile pattern and use it to find out how many tiles will there be in figure 32?
Dafna11 [192]

9514 1404 393

Answer:

  98

Step-by-step explanation:

The numbers of tiles are 5, 8, 11. This is an arithmetic sequence with a first term of 5 and a common difference of 3. The n-th term is ...

  an = a1 +d(n -1)  . . . . . for first term a1 and common difference d

This sequence has n-th term ...

  an = 5 +3(n -1)

Then the 32nd term is ...

  a32 = 5 + 3(32 -1) = 5 +93 = 98

Figure 32 will have 98 tiles in it.

Find f(x) and g(x) so the function can be expressed as y = f(g(x)). y = (8/x^2) + 4
rjkz [21]
Y=f(g(x))      and      y= \frac{8}{x^{2}}+4


our aim is to express f as a function of g, where g is a function itself, of x.

in the expression tex]y= \frac{8}{x^{2}}+4 [/tex] we may notice 2 functions:

the squaring x function, which may well be our g: g(x)= x^{2}

and the "8 divided by x, +4" function: f(x)= \frac{8}{x}+4


check : 

f(g(x))= \frac{8}{g(x)}+4

because whatever the input of f is, it divides it from 8, and adds 4 to the division. 

since, g(x)= x^{2}, 

f(g(x))= \frac{8}{g(x)}+4=\frac{8}{x^{2}}+4


Answer:

g(x)= x^{2}

f(x)= \frac{8}{x}+4
