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

The manager of a fashionable restaurant open Wednesday through Saturday says that the restaurant does about 29 percent of its bu
RideAnS [48]

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 = \frac{y}{4}

If we assume that y = 1

hence, average sales in a week = \frac{1}{4}

= 0.25

Now, we have to calculate the seasonal relatives,

that is,

=  \frac{Sales in a given day}{average sales in a week}

Wednesday:

= \frac{0.19}{0.25}

= 0.76

Thursday:

= \frac{0.21}{0.25}

= 0.84

Friday:

= \frac{0.29}{0.25}

= 1.16

Saturday:

= \frac{0.31}{0.25}

= 1.24
