Answer:
Slope of the tangent line at x=-1
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given function
y = f(x) = e ˣ⁻⁴ ...(i)
Differentiating equation (i) with respective to 'x' , we get
Slope of the tangent line
about 65 days
46/30 = 1.53 pounds per day
100/1.53 = about 65
1.) 2.5 meters a second
1 min 12 seconds is 72 seconds. 28 meters on 72 seconds. 28×2.5=72
