Answer:
24) x = 9.2
25) x = 30.8
Step-by-step explanation:
Given
See attachment for triangles
Solving (24)
To solve for x, we make use of cosine formula
i.e.
cos(40) = adjacent ÷ hypotenuse
So, we have:
cos(40) = x ÷ 12
Multiply both sides by 12
12 cos(40) = x
12 * 0.7660 = x
x = 9.2
Solving (25)
To solve for x, we make use of sine formula
i.e.
sin(25) = opposite ÷ hypotenuse
So, we have:
sin(25) = 13 ÷ x
Multiply both sides by
x sin(25) = 13
Divide by sin(25)
x = 13 ÷ sin(25)
Using a calculator
x = 30.8
Answer:
20
Step-by-step explanation:
math lol and it's the correct answer
Answer:
- Amplitude is -5
- Period is 2π
- phase shift is -2π
Step-by-step explanation:
We can write a general wave function equation as:
Where:
- A is the amplitude .
- 2π/B is the period
- C is the phase shift
- D is the vertical shift
Our equation is:
Hence, comparing both equation we will conclude:
- Amplitude is -5
- Period is 2π
- phase shift is 2π
I hope it helps you!
