Answer:
Step-by-step explanation:
First find the midpoint of the segment from (2, -6) to (-4, -16)
((2 - 4)/2, (-6 - 16)/2)
(-2/2, -22/2)
(-1, -11) is the midpoint and is the center of the circle
Now find the distance between the 2 given points and divide by 2 to get the radius of the circle
d =
=
=
=
r = /2
= 136/4 = 34
Equation of circle with center at (-1, -11) and radius = is
Given:
In a number, adding , then multiplying the result by
we get 8.
To find:
The unknown number.
Solution:
Let the unknown number be x.
According to the question,
Multiply both sides by .
Subtract from both sides.
Therefore, the required number is .
Answer:
i. When the temperature is above F, it changes to gas.
ii. When the temperature is below F, it changes to solid.
Step-by-step explanation:
Matter generally exists in either a solid, liquid or gaseous form. With each phase having a certain range of temperature.
Temperature scale of a given substance can be either in Celsius, Fahrenheit or Kelvin. And conversion from one scale to another can be achieved. Example, Celsius scale can be converted to Fahrenheit by:
F = θ + 32
where: F is the equivalent temperature in Fahrenheit, θ is the value of temperature in degree Celsius.
Given that: melting point of the substance = C
⇒ F = x
+ 32
= F
The boiling point = C
F = x
+ 32
= F
The melting point of the substance is F, and boiling point is
F.
Therefore, the range of temperatures for which the substance is not in a liquid state are:
i. When the temperature is above F, it changes to gas.
ii. When the temperature is below F, it changes to solid.
