Find the linear function Cequals​f(F) that gives the reading on the Celsius temperature scale corresponding to a reading on the

Fahrenheit scale. Use the facts that Cequals0 when Fequals32 ​(freezing point) and Cequals100 when Fequals212 ​(boiling point). b. At what temperature are the Celsius and Fahrenheit readings​ equal?

Answer:

C = (5/9) F - (160/9)

They both read equal at Z = - 40

Explanation:

We are looking for a linear function so we can write the following condition

Y = aX + b

Applying it to the exercise we got C = a F + b

Let's use the facts that C = 0 when F = 32 and C = 100 when F = 212

0 = 32 a + b            (1)

100 = 212 a + b       (2)

From (1) b = - 32 a , when we replace this in (2) we obtain a = (5/9)

and b = - (5/9)32 = - 160/9

Finally the linear function is C = (5/9) F - (160/9)

Both readings are equal at a Z number so

Z = (5/9) Z - 160/9

(4/9) Z = -160/9 and Z = - 40

What statement is true about the eight elements on the periodic table termed metalloids?
valina [46]

Answer:

They have properties of both metals and nonmetals

Explanation:

  • Elements in the periodic table may be divided into Metals, non-metals, and metalloids.
  • Metals are the elements that react by losing electrons to form stable positively charged ions known as cations. Examples are group 1, 2, and 3 elements together with transition elements.
  • Non-metals are those elements that react by gaining electrons to form stable negatively charged ions called anions. Examples include oxygen, carbon, sulfur, etc.
  • Metalloids, on the other hand, are elements that have both metallic and non-metallic properties.
  • Metalloids occur between metals and non-metals in the periodic table. Examples include Boron and silicon among others.
