Answer:
Step-by-step explanation:
The four walls have a linear length of (9 m)×4 = 36 m. Of that, the two 1-meter doors are not painted, so the linear length of the painted area is 34 m. The painted area is 2 m high, so the total area being painted is ...
A = LW
A = (34 m)(2 m) = 68 m²
The amount of paint needed for this area is ...
(68 m²) × (1 L/(10 m²) = 6.8 L
If we assume the paint only comes in units of 1 L, then Heather will need 7 L of paint.
The cost of 7 L of paint is ...
(7 L) × ($3.75/L) = $26.25
Heather will need 7 L of paint, for a total cost of $26.25.

The satellite makes 8 revolutions around the earth, it passes 177272 kilometers.
<h3>
How many kilometers does the satellite make
8 revolutions around the earth
?</h3>
The orbital velocity of the satellite exists independent of its mass. The radius of the orbit exists as the only variable. If the satellite orbits near the planet at such a low height, its orbital speed must be extremely fast. If the orbital speed exists less than the required value, the satellite will be drawn to the earth's surface by gravity.
The satellite rotates around the earth to form a circle,
diameter of circle = Diameter of earth + 2(Height)
d = 6714 + 2(343)
d = 6714+ 686
d = 7057
Perimeter = πd
Perimeter = 3.14 (7057)
Perimeter = 22158.98
Total Revolution exists 8
Therefore, 8πd = 8(22158.98)
= 177272 kilometers.
Therefore, the satellite makes 8 revolutions around the earth, it passes 177272 kilometers.

The change represents decay and the percentage decrease is 2.9%
<h3>Exponential function</h3>
The standard exponential function is expressed as y = ab^x
where:
a is the initial
b is the rate
If the value of b is less than 1 hence the function is decay and if greater than 1, the function is growth
GIven the expoenential function y=100(0.971)^x
Since the value of b = 0.971 < 1, hence the function is a decay.
The percentage decrease = 1 - 0.971 = 2.9%
Hence the percentage decrease is 2.9%

Step-by-step explanation:
You will divide 16 into 6,832 then you will do 16 times 4 and it will give you 64 and you subtract that and you will get 43 and then do 16 times 2 and you will get 32 and you subtract 43 and 32 then you will multiply 16 times seven and you will get 112 and subtract that by 112 and you will get zero.
