In air, the speed of sound S, in meters per second, is a linear function of the air temperature T, in
degrees Celsius, and is given by S(T) = 0.6T + 331.4.
Which of the following statements is the best
interpretation of the number 331.4 in this context?
A) The speed of sound, in meters per second, at
0°C
B) The speed of sound, in meters per second,
at 0.6°C
C) The increase in the speed of sound, in meters per
second, that corresponds to an increase of 1°C
D) The increase in the speed of sound, in meters per
second, that corresponds to an increase of 0.6°C

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
