Answer: She will need 142 ft of curtain.
Step-by-step explanation:
Hi, first we have to convert the length of the curtain from inches to foot.
Since 1 inch = 1/12ft
For 24 inches:
24 inches x 1/12 = 2 ft
Since the company wants to make 71 curtains, we have to multiply the length of each curtain (2ft) by 71.
2ft x 71 = 142ft
She will need 142 ft of curtain.
Feel free to ask for more if needed or if you did not understand something.
Part A: f ( t ) = t² + 12 t - 19 =
= ( t² + 12 t + 36 ) - 36 - 18 = ( t + 6 )² - 54 ( the vertex form )
Part B : The vertex : ( - 6, - 54 ). This is the minimum, because the parabola is open up ( a > 0 ).
Part C : The axis of symmetry: t = - 6
Its H and K.... they are the only 2 dots that are not in the close group
0.3×8=2.4
1.5×3=4.5
(2.4+4.5)+36=42.9
