Equation 2x² + 5x - 42 = 0
-Factor
2 x 42 = 84
- Find the prime factors of 84
84 2
42 2
21 3
7 7
1
84 = 2² 3 7
-Find two numbers that added gives 5
These numbers are 12 and -7
- Express the equation using these numbers
2x² + 12x - 7x - 42
-Factor by common factor
2x(x + 6) -7(x + 6)
-Factor by grouping
(x + 6)(2x - 7)
-Find the roots
x₁ + 6 = 0 2x₂ - 7 = 0
x₁ = -6 2x₂ = 7
x₂ = 7/2
For this case what you have to take into account is the following trigonometric definition:
Tan (x) = (C.O) / (C.A)
Where,
x: angle
C.O: opposite leg
C.A: Adjacent cateto.
We have then:
The tangent ratio is the ratio of the side opposite the angle of the side to the angle.
Answer:
opposite, adjacent
Answer:
Value of retrun invesment is 2062.5
Step-by-step explanation:
Shares total price = 3000 × 1.75 =
Shares total price = 5250
25% dividend = (5250 × 25)÷100 = 1312.5
Add them 5250 + 1312.5 = 6562.5
Sold total price = 3000 × 1.50 = 4500
To find return of invesment subtract
6562.5 - 4500 = 2062.5
