Step-by-step explanation:
The attachment above is a table summarizing everything.
so the answer should be - 0.5
Answer:
b < -10 and (-∞, -10)
Step-by-step explanation:
I won't draw the number line but I will do the interval notation.
Interval notation is a way to describe infinite or finite sets with numbers.
To solve the inequality first add 2 to both sides to get:
-b > 10 Multiply both sides by -1:
b < -10 is the simplification of the inequality .
Now to write this in interval notation you need to know which direction the values are increasing, since b is less than -10, the values are going down starting from -10 (not including -10).
Interval notation: (-∞, -10)
Answer:
3
Step-by-step explanation:
Tan θ = 7/8
θ = tan^-1 (7/8) = 41.2 degrees
cos θ = 0.7526
