Answer:
The number of movies purchased is 5
Step-by-step explanation:
40.00 + 3.50 = 43.50
43.50 + 3.50 = 47.00
47.00 + 3.50 = 50.50
50.50 + 3.50 = 54.00
54.00 + 3.50 = 57.50
so if you add 3.50 to 40, 5 times you'll get 57.50
Hope it helped
Answer:
Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.
Step-by-step explanation:
The equation f(x) given is:

For x = 0. the value of the expression is:

For x = 1, the value of the expression is:

Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.
In other words, there is at least one solution for the equation between x=0 and x=1.

Answer:
The speed of jogger in uphills is 4 mile per hour
And The speed of jogger in downhills is 10 mile per hour
Step-by-step explanation:
Given as :
The distance cover by jogger in downhill (Dd) = 5 miles
The distance cover by jogger in uphill (Du) = 2 miles
The time taken by jogger in downhill (Td) = T hour
The time taken by jogger in uphill (Tu) = T hour
Let The speed of jogger in uphills (Su) = x mph
So ,The speed of jogger in downhills (Sd) =( x + 6 ) mph
∵, Time =
So, Tu =
Or, T =
h
And Td =
Or, T =
h
∵ Time duration of both is same
∴
= 
Or, 2 × (x + 6) = 5x
Or, 2x + 12 = 5x
So, 12 = 3x
∴ x =
= 4 mph
And x + 6 = 4 + 6 = 10 mph
Hence The speed of jogger in uphills is 4 mile per hour
And The speed of jogger in downhills is 10 mile per hour Answer
