Answer:
- -√5
- 3/5
- -4/5
Step-by-step explanation:
The relevant relations are ...
sec = ±√(tan² +1)
cos = 1/sec
csc = 1/sin = ±1/√(1 -cos²)
Sine and Cosecant are positive in quadrants I and II. Cosine and Secant are positive in quadrants I and IV.
__
1. sec(θ) = -√((-2)² +1) = -√5
2. cos(θ) = 1/sec(θ) = 1/(5/3) = 3/5
3. csc(θ) = -1/√(1 -(-3/5)²) = -√(16/25) = -4/5
Answer:
3/5
Step-by-step explanation:
1/3s=1/5
s=(1/5)/(1/3)
s=(1/5)(3/1)
s=3/5
Answer:
k=7
Step-by-step explanation:
Add 15 to both sides, -8+15=7
So, K=7

In order to find the<u> roots</u> of the cubic equations by <u>graphing</u> you have to follow those steps
we have
we know that
The <u>roots</u> of the function are the values of x when the value of the function is equal to zero
Using a <u>graphing </u>tool
see the attached figure
The<u> roots</u> are
therefore
the answer is
