Hi There!
Inequality:
v>83
This inequality says that
v is greater than $83.
Hope it helps!
Have an awesome day!

Answer:
Applied the definition and the limit.
They had the same result, so the function is continuous.
Step-by-step explanation:
At function f(x) is continuous at x = a if:

In this question:

At x = 3.


Since
, f(x) is continuous at x = 3.
Answer:
5 seconds
Step-by-step explanation:
H= -16t2 + 400
Hit ground
H=0
0 = -16t2 + 400
0 = -16 ( t2 - 25)
-16
t2 -25 = 0
(t + 5)(t - 5) = 0
t + 5 = 0
- 5 -5
t = -5
t - 5 = 0
+ 5 +5
t = -5
t = 5
5 seconds to hit the ground
Tan(tan−1(yx)−θ) is the slope m. Then use "point slope formula" (if you want an equation of the line, that is...) Labeling the origin "O" and the point (x,y) "P", the segment ¯OP makes an angle of tan−1(yx) with the positive x-axis
