Answer:
4
Step-by-step explanation:
Slope refers to the steepness of the line.
Slope is equal to change in value of y divided by change in value of x.
The slope of the secant line is given by
.
Given points are 
So, slope of the secant line is 
(i) At x = 4.9,

(ii) At x = 4.99,

(iii) At x = 4.999,

(iv) At x = 4.9999,

(v) At x =5.1,

(vi)
At x = 5.01,

(vii) At x = 5.001,

(viii) At x = 5.0001,

(b)
Slope of the tangent line is 4.
Answer:
a 1.6 miles
Step-by-step explanation:
1/8 hour=7.5
60/7.5=8
1/5*8=1.6
A. d=50t B. 50,100,150,200,250 C. 50 days
The answer is 30°.
Rule: All three sides must add up to 180°.
Since A=60 and the side vertical to the angle which is 90° then side C would be C=90° and that adds up to 150°, so you can conclude that angle B is 30°.
