Answer:
Step-by-step explanation:
Height of wall = 10ft
Length of ladder = 12ft
Angle of elevation be x
Sin x = opp/hyp
Sin x = wall height/length of ladder
Sin x = 10/12
Sin x = 0.83
X = Sin-¹ (0.83)
X = 56.44°
Answer: first one Y
Explanation: it is easy math
Answer:
<em>m</em> = 6
Step-by-step explanation:
The definition of a derivative is the slope of the tangent line.
Step 1: Define
f(x) = x² + 4x - 3
Point (1, 2)
Step 2: Find slope of tangent line
- Find derivative of f(x): f'(x) = 2x + 4
- Plug in <em>x</em> coordinate into derivative to find slope: f(1) = 2(1) + 4 = 6
