Absolute zero is shown as 0 on the Kelvin Scale.
Answer:
it is a parallelogram
Step-by-step explanation:
so first plot out points and then you find the slope for each of the corresponding lines.
First lets find the slope for AB. you must subtract them and make it -2-1/-2-1. it ends up having a slope of 1.
Then find the slope of the corresponding side(CD). this we will subtract -2-1/3-6. this will have a slope of 1 and will be parallel to AB.
Next you find the slopes of the other two sides starting with AC. we will subtract -2-(-2)/-2-3. this will be a vertical line which means it has a slope of 0.
finally the last step is you see if BD has an equal slope to AC. you then subtract 1-1/1-6. this is also a vertical line so the slope is 0 just like AC so they are both parallel.
in conclusion there are two sets of parallel lines so you have a parallelogram
The car will be worth after one year is £ 5753.6.
<h3>What is exponential function?</h3>
An exponential function is defined by the formula f(x) =
, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x.
The exponential function is an important mathematical function which is of the form
f(x) = 
Where a > 0 and a is not equal to 1.
x is any real number.
Given
Car cost when bought A = £ 6200
Value of a car decreases by 7.2% each year.
n = 1
r = 7.2% or 0.072
The car will be worth after one year

⇒ 
⇒ 
⇒ y = £ 5753.6
Hence, the car will be worth after one year is £ 5753.6.

Answer:
-3 , 6
Step-by-step explanation:
Let x be the price for each night and y be the price for each meal. Then, express the statements into mathematical equations:
Choice A: 3x + y = 250
Choice B: 3x + 6y = 330
Subtract both equations, the difference would be -5y = -80
-5y = -80
y = -80/-5
y = $16 per meal
3x + y = 250
3x + 16 = 250
3x = 250 - 16
3x = 234
x = 234/3
x = $78 per night
The answer is D.
