Answer:
65.60
Step-by-step explanation:
First find the markdown
markdown = original price times the percent markdown
= 80* 18%
= 80 * .18
14.4
Take the markdown from the original price to find the retail price
80-14.4 =65.60
Answer:
2 solutions
Step-by-step explanation:
the reason is because the line passes through the parabola twice which thus gives it two solutions due to there being two points
Answer: The answer is that the length is square ft, and the width is .
Step-by-step explanation:
Sinα=h/w
w=h/sinα, we are told that h=15 ft and α=70° so
w=15/sin70° ft
w≈15.96 ft (to nearest hundredth of a foot)
Answer:
y+2=1/2(x-8) or y+4=1/2(x-4)
Step-by-step explanation:
Okay, so point slope form is y-y1=m(x-x1). So you substitute y1 with -2 or 8 and x1 with 8 or 4.
Slope is (-2-(-4))/(8-4), which is 2/4, or 1/2. Plug that into m.
