identifying equation in point slope form for the line perpendicular to y equals negative 1 / 3x - 6 that passes through -1,5
1 answer:
Answer:
y = 3x +8
Step-by-step explanation:
The slope of the given line is -1/3. The slope of a perpendicular line is the opposite of the reciprocal of that: -1/(-1/3) = 3.
Then, in point-slope form, the equation of the line is ...
... y - k = m(x - h) . . . . . for slope m through point (h, k)
... y - 5 = 3(x -(-1)) . . . . . for line of slope 3 through (-1, 5)
... y = 3x +8 . . . . . . . . . simplify

Answer: The seasonal relatives is calculated are as follows:
Step-by-step explanation:
Given that,
restaurant only open from Wednesday to Saturday,
- 29 percent of its business on Friday
- 31 percent on Saturday night
- 21 percent on Thursday night.
∴ The remaining 19% of its business he does on Wednesday
Now, suppose that total production of sales in a given week be 'y'
So, average sales in a week =
If we assume that y = 1
hence, average sales in a week =
= 0.25
Now, we have to calculate the seasonal relatives,
that is,
=
Wednesday:
=
= 0.76
Thursday:
=
= 0.84
Friday:
=
= 1.16
Saturday:
=
= 1.24
