Answer:
Option D. − 8/5
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
we have the points
(−1, 7) and (4, −1)
substitute in the formula
Answer:
Hence, 0.041 can be expressed as .
Step-by-step explanation:
- Given 0.041
- Use given, move the decimal point so that first factor is greater than or equal to 1 but less than 10 .
- Then count n and write in scientific notation.
Step 1 of 1
Consider 0.041
Decimal has moved to 2 places at right.
The power will be negative as original no. is less than 1 .
So,

9≈56.54867
Answer:
X=1/2
Step-by-step explanation:
-2x1/2=-1
-2x1=-2
-1+-2=-3
Step-by-step explanation:
1. All the trigonometric values can be found using the unit circle. See attached table.
2. Graph:

3. All trig functions are periodic functions. The period of secant and cosecant is 2π. The period of cotangent is π.
4. Using the table from step 1 and the graph from step 2, secant has a domain of x ≠ pi/2, 3pi/2 and a range of x ≤ -1, x ≥ 1. Cotangent has a domain of x ≠ 0, pi, 2pi and a range of -∞ < x < ∞.
5. Graph:

Cosecant has the same graph as secant shifted π/2 to the right. So they have different domains, but the same range.
