the answer to the question is F= -5.37
Answer:
Below.
Step-by-step explanation:
- tan 2x = -2tanx / (1 - tan^2x)
Using the identity tan^2x = sec^2x - 1 and substituting for tan^2x:
- tan 2x = -2 tanx / (1 - (sec^2x - 1))
= 2 tanx / ( - 1(sec^2x + 2))
= 2 tan x / (sec^2 x - 2)
16)
(4x + 2) is equal to 150 because they are vertical angles. When two lines intersect, on the opposite sides of the x like these are will be equal to one another. So let’s make them equal to each other.
4x + 2 = 150
Subtract 2
4x = 148
Divide by 4
x = 37
So it will be A
17)
The two angles added up with each other
34 + 146 = 180
Since these two add up to 180 degrees, they would be supplementary angles.
So, H
18)
The two angles will make a 90 degree angle (as shown with the little box formed in the corner)
When angles add up to make 90 degrees, they will be complimentary angles.
So, C.
The correct answer is: [C]: " $ 1.58 " .

Explanation:
______________________________________________
Given:
______________________________________________
$18.99 per 340.23 grams ;
and given:
1 gram ≈ 0.03527 oz (ounces) ;
______________________________________________
Find the unit price per OUNCE (oz).
______________________________________________
Given: $18.99 per 340.23 grams ;
Convert: "340.23 grams" to "ounces (oz)".
Given: "1 gram ≈ 0.03527 oz" ;
340.23 grams = (340.23 * 0.03527) oz. = 11.9999121 (about "12 oz.").
So, $19 / 12 oz. = ? dollars per UNIT OZ. ; =
(19/12) dollars per oz. = (19÷12) dollars per oz. = $ 1.58333 ; which corresponds to: Answer choice: [C]: $1.58 .
