Answer:
Step-by-step explanation:
step 1
we have the points
(-1,0), (-2,0), and (0,2)
Plot the points
using a graphing tool
see the attached figure
The graph of a quadratic function must be a vertical parabola open upward
The vertex is a minimum
The quadratic function in general form is equal to
Substitute the value of x and the value of y of each given ordered pair in the general equation and solve for a,b and c
(0,2)
For x=0, y=2
substitute
(-1,0)
For x=-1, y=0
substitute
----> 
----> equation A
(-2,0)
For x=-2, y=0
substitute
----> equation B
we have the system
----> equation A
----> equation B
substitute equation A in equation B
solve for b
Find the value of a
therefore
The quadratic function in general form is equal to
see the attached figure N 2 to better understand the problem
Answer:
Since the footrest measures 1.54 square yards, Alice will not be able to cover it completely.
Step-by-step explanation:
Since Alicia wants to cover a footrest in the shape of a rectangular prism with cotton fabric, and the footrest is 14 inches by 11 inches by 13 inches while she has 1 square yard of fabric, to determine if she can she completly cover the footrest the following calculation must be performed:
1 square yard = 1296 square inches
14 x 11 x 13 = X
154 x 13 = X
2.002 = X
2.002 / 1.296 = 1.54
Thus, since the footrest measures 1.54 square yards, Alice will not be able to cover it completely.
(3.2 • 10^8)(1.3 • 10^9)
= 4.16 • 10^17 in scientific notation
