Answer:
the answer is 20
Step-by-step explanation:
The answer is 20. The rule of math, for this math problem, is that you do the multiplication first and then solve. Order of operations is "PEMDAS," which explained is by following these rules: Parentheses First.
Answer:
The answer to your question is
sin Ф = 0.731 and sinФ = -0.731; cos Ф 0.682 and cos Ф = -0.682
Step-by-step explanation:
tan Ф = 1.072, 0 < Ф < 2 π, tan Ф is positive, find the solution in the first and third quadrangle.
- tan Ф = opposite side / adjacent side
- 1.072 / 1 = opposite side / adjacent side
- opposite side = 1.072 and adjacent side = 1
Calculate hypotenuse
c² = a² + b²
c² = 1.072² + 1²
c² = 2.149
hypotenuse = c = 1.466
First quadrangle
sin Ф = 1.072 / 1.466 = 0.731
cos Ф = 1 / 1.466 = 0.682
Third quadrangle
sin Ф = -1.072 / 1.466 = -0.731
cos Ф = -1 / 1.466 = -0.682
-5/16
Our choices:-
A.-3/8
B.-11/12
C.-1/4
<span> D.-1/8

Let us get all of them with a LCD
-1*2 = -2
8*2 = 16
-2/16 is not bigger than -5/16
-11/12 is bigger than -5/16 because half of 16 is 8.
-1*4 = -4
4*4= 16
-4/16 is not bigger than -5/16
-1/8 is smaller than -5/16
Final answer: -11/12 is the only fraction bigger than -5/16
