The tangent slope is *defined* as 
. (this relates to the function tangens, tan, of an angle).
Because it is defined as a ratio of the change in y to the change in x, both coordinates are needed. Having only one coordinate, the slope would be undetermined. Lmk if you have questions.
Answer:
No they are equivalent
Step-by-step explanation:
3/7 =21/35
3/5=21/35
Temp. at 6 pm. was 72...
that temp. was 8 less then at 4 pm....so at 4 pm, it was 72 + 8 = 80
the temp. at 10 am was 5 greater then at 4 pm.....so at 10 am, it was 80 + 5 = 85 F <===
Yes, 5 goes into 100 exactly 20 times because 5 multiplied by 20 is 100
For
the derivative is negative.
For
the derivative is positive.
Therefore at
there's a minimum.
