Answer:
Step-by-step explanation:
Given that there is a function of x,
Let us find first and second derivative for f(x)
When f'(x) =0 we have tanx = 1 and hence
a) f'(x) >0 for I and III quadrant
Hence increasing in 
and decreasing in 
Hence f has a maxima at x = pi/4 and minima at x = 3pi/4
b) Maximum value = 
Minimum value = 
c)
f"(x) =0 gives tanx =-1
are points of inflection.
concave up in (3pi/4,7pi/4)
and concave down in (0,3pi/4)U(7pi/4,2pi)
This is geometric with a common ratio of 3 (3/1 = 3 and 9/3 = 3 etc)
the formula for the nth term is
an = 3^(n-1)
Multiply 4 and 30. If the answer is 120, then you are correct.
Answer:
$35
Step-by-step explanation:
25% ×28 =7.
28 + 7 = 35
First we can change the miles per hours into feet per hour. Every mile is 5280 feet so multiply 58 by 5280. 58*5280=306,240. Now you have 306,240 feet per hour which you then divide by 60 twice to get per second. 306,240/60=5,104ft per minute now divide again to find per second. 5,104/60≈85.1feet per second.
