Find the area of the regular polygon
Answer:
12
Step-by-step explanation:
There are 6 sides of the polygon, therefore since each corner is "2m", 2 x 6 = 12 making it the whole area.
*12 is basically the same as 360 since it's a polygon*
Find the equation of the given line.
Find the equation of the line passing through
(5, 6) and (7, 9).
Answer:
y = 3/2x - 1.5
Step-by-step explanation:
m = y² - y¹ / x² - x¹
= 9 - 6 / 7 - 5
= 3/2
(5,6)
y = mx + c
6 = 3/2 (5) + c
6 = 7.5 + c
6 - 7.5 = c
c = -1.5

A pizza is removed from the oven at a temperature of 425 F. After 15 minutes, the pizza has
cooled to 200°F. Use a continuous exponential decay model to find the approximate decay
rate.
WILL MARK BRAINLIEST!! 20 POINTS!
Answer:
The decay rate is of 0.05 = 5% per minute.
Step-by-step explanation:
Continuous exponential decay model:
The exponential equation of decay for an amount, after t units of time, is given by:
[tex]A(t) = A(0)e^{-rt}[/tex]
In which A(0) is the initial amount, e(approx 2.72) is the Euler value and r is the decay rate, as a decimal.
A pizza is removed from the oven at a temperature of 425 F.
This means that [tex]A(0) = 425[/tex]
After 15 minutes, the pizza has cooled to 200°F.
This means that [tex]A(15) = 200[/tex], that is, when [tex]t = 15, A(t) = 200[/tex]
We use this to find r.
[tex]A(t) = A(0)e^{-rt}[/tex]
[tex]200 = 425e^{-15r}[/tex]
[tex]e^{-15r} = \frac{200}{425}[/tex]
[tex]\ln{e^{-15r}} = \ln{\frac{200}{425}}[/tex]
[tex]-15r = \ln{\frac{200}{425}}[/tex]
[tex]r = -\frac{\ln{\frac{200}{425}}}{15}[/tex]
[tex]r = 0.05[/tex]
The decay rate is of 0.05 = 5% per minute.

-16p was my answer after simplifying it
Answer:
120p - 16p = 104p
Step-by-step explanation:
-3p x -3p = 9p + 6p = 15p x 8p = 120p
8p x -2 = -16p
120p - 16p = 104p

A 108-inch pipe is cut into two pieces. One piece is five times the length of the other. Find the lengths of the two pieces.
The short piece is
inches long
Answer:
18 and 90
Step-by-step explanation:
If we express in units,
Long piece has 5 units
Short piece has 1 unit
total 6 units
108/6 = 18 inch
which is the length of 1 unit
short = 18 * 1
long = 18 *5

What is an obtuse angle?An obtuse angle is any angle greater than 90° and less than 180°.
From option A:
100° angle is an obtuse angle, because which is greater than 90° and less than 180°.
From option B:
175° angle is a reflex angle because it is greater than 180° and less than 360°.
From option C:
Less than 90° lies in I quadrant, more than 90° and less than 180° lies in II quadrant and more than 180° and less than 270° lies in III quadrant.
From option D:
An 85° angle is an acute angle because it is greater than 0° and less than 90°.
