In science class a student was measuring the temperature of a solution during an experiment.
The solution started out at -2.7°C. After three minutes the temperature had increased
by 17.8°C. After three more minutes it had decreased by 29.5°C. Then after three more
minutes it had increased by 8.9°C.
Which number represents final temperature in this experiment?
A. -5.5°C
B. -2.8°C
C. 2.8°C
D. 5.5°C

it is c

Step-by-step explanation:

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
