Over [174]

Answer:

Answer

0.109589 millimeters per day.

Explanation

10 mm = 1 cm

4 cm = 4 × 10

        = 40 mm

365 days = 1 year

rate to millimeters per day = 40 mm in 365 days

                                            = 40/365  mm/day

                                             = 8/73 mm/day

                                       or    = 0.109589 mm/day.

Rate to millimeters per day = 0.109589 millimeters per day.

A line includes the points (8,5) and (9, – 5). What is its equation in point-slope form?
zmey [24]

Answer:

Step-by-step explanation:

slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

         =\frac{-5-5}{9-8}\\\\=\frac{-10}{1}\\\\=-10\\

Point-slope form:

y - y1 = m(x - x1)

y - 5 = -10(x - 8)

Find the perimeter of the following shape (show all work and box your final answer):
Paraphin [41]
<h3>Answer:   11x + 6y + 11</h3>

=========================================

Work Shown:

To find the perimeter, we add up all the exterior side lengths.

P = perimeter

P = (side1) + (side2) + (side 3)

P = (2y-3x-3) + (12+5x+7y) + (9x-3y+2)

P = (-3x+5x+9x) + (2y+7y-3y) + (-3+12+2)

P = 11x + 6y + 11
