1. SOH CAH TOA tells you the tangent is the ratio of the Opposite side to the Adjacent side, that is, 4/3. (This correct answer is not among your choices.)
2. The mnemonic SOH CAH TOA can be helpful here. It tells you
... Sin = Opposite/Hypotenuse
... Cos = Adjacent/Hypotenuse
... Tan = Opposite/Adjacent
3. Reference the ratios listed above (for the second problem). You see that sin(α) = cos(90°-α). That is, the sine of an angle is the cosine of its complement and vice versa. The appropriate choice is
... D. 19/20
Answer:
Step-by-step explanation:
-6 ≥ x
-2 ≤ x
I don't think you can combine this into one statement.
Your line looks something like
<---------------O O------------------------->
-6 -2
Shade in the 2 Os. The shaded in Os are included in the way the line looks.
Answer: The answer is letter B "No; a range value has two domain values".
For a relationship to be a function, there must be a one-to-one correspondence between the x and y values. For every value of x, there must be only one value for y. So the first set is a function and the second set is not.
Answer:
No; a range value has two domain values.
Step-by-step explanation:
Output has to be unique for all inputs.
Output for -2 is not unique
Step-by-step explanation: It is either B or C
Since
x = −
2
produces
y = 1
and
y = 2

Step-by-step explanation:
5x+15+2=5x+17
2 Simplify 5x+15+25x+15+2 to 5x+175x+17.
5x+17=5x+17
5x+17=5x+17
3 Since both sides equal, there are infinitely many solutions.
