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](https://tex.z-dn.net/?f=2%5Cpi%20r)
is the radius of the circle.
Radius is half of perimeter.
![r=\dfrac{18}{2} = 9\ inches](https://tex.z-dn.net/?f=r%3D%5Cdfrac%7B18%7D%7B2%7D%20%3D%209%5C%20inches)
Perimeter of the Pac-Man poster = Perimeter of
circle + 2 sides
Perimeter of the Pac-Man poster =
+ 9+9 = 42.39+28 = <em>60.39 inches</em>
Something funny is that the x value of the vertex lies directl in the middle of the x intercepts
so
we see the x intercepts or 0's at x=8 and 2
the average is x=5
so find f(5) to find the y value of the vertex
f(5)=(5-8)(5-2)
f(5)=(-3)(3)
f(5)=-9
vertex is at (5,-9)
the actual way the teacher wants is to expand then compltete the square to get into the form f(x)=a(x-h)^2+k where the vertex is (h,k)
but whatever
verrtex is at (5,-9)
Answer:
C, HL
Step-by-step explanation:
Since the triangles share a side, they have a congruent leg. Looking at the tick marks, the triangles also have congruent hypotenuses. So, they are congruent by the Hypotenuse Leg theorem.
Let no. of large bags = l
Let no. of small bags = s
4l * 2.5s = 50
He will buy 6 large and 10 small bags.(49$)
