Answer:
Step-by-step explanation:
we know that
The quadratic function of the figure has a vertex at (2,-5) and the y-intercept is the point (0,3)
The equation of a vertical parabola in vertex form is equal to
where
(h,k) is the vertex
a is a coefficient
we have
substitute
with the y-intercept find out the value of a
For x=0,y=3
The equation is
Looking at the graph, the solution is the shaded area below the quadratic equation
so
the value of y must be less than or equal to the quadratic function
Answer:
5 pieces
Step-by-step explanation:
Given:
Paula's painting has a perimeter of 1.22 meters.
She wants to put ribbon around the edge.
If the ribbon comes in pieces that are 25 centimeters long.
Question asked:
How many pieces of ribbon does she need to go all the way around her painting?
Solution:
Perimeter of painting = 1.22 meters
First of all we will convert it into centimeters:-
As we know:
1 meter = 100 centimeters
1.22 meters = 100 1.22 = 122 centimeters
Now, as given that ribbon comes in pieces of 25 cm long and total we should have 122 cm to go all the way around the painting.
Number of pieces of ribbon will be needed =
Thus, she need 5 pieces of 25 cm long ribbon to go all the way around the painting.
<u>Note</u>:-This is by default understood that few length of 5th ribbon will be left over.
