Answer: option 3 is the correct answer
Step-by-step explanation:
Let us look at the various trigonometric ratios
Sin Ф = opposite side/ hypotenuse
Cos Ф = adjacent side / hypotenuse
Tan Ф = opposite side / adjacent side
Therefore, tan Ф = sin Ф / cos Ф
This means that if cos Ф=-8/17 and sin Ф is negative, then the hypotenuse is negative
To determine the adjacent side, we will apply Pythagoras theorem
Hypotenuse ^2 = opposite ^2 + adjacent ^2
-17^2 = 8^2 + adjacent^2
adjacent^2 = 289 - 64 = 225
adjacent = √225 = 15
tan Ф = 8/15
Four times a number is equal to negative eight.
Slope formula is y2-y1/x2-x1.
Using this, we can say that -3 – 2/5 – 0=

Well as it looks like to me the cords of the a,b,c are 2,3,1
Answer:
1. No.

Since f(1)=f(3) and
then f isn't one-to-one.
2. No

Since f(0)=f(2) and
then f isn't one-to-one.
3. No

Since f(0)=f(2) and
then f isn't one-to-one.
4. Yes

Since
, then f is one-to-one
5. Since f(1)=f(3) and
then, f isn't one-to-one
