Hello :
<span>x-coordinates for the maximum points in the function f(x) = 4 cos(2x − π) from x = 0 to x = 2πis solutions of : f'(x) =0
f'(x) = - 2sin</span><span>(2x − π)
</span>- 2sin(2x − π) =0
sin (2x − π) =0
2x − π = kπ ... k in Z
x=(k+1)π/2....(general solutions in R)
<span>from x = 0 to x = 2π :
</span>k =0 : x = π/2
k=1 : x= π
k=2 : x= 3π/2
k = 3 : x=2π
Remains to be determined whether it is a maximum or minumum
Answer:
Step-by-step explanation:
23x + 1 = 3x - 2
23x - 3x +1 = -2
20x + 1 = -2
20x = -2 - 1
20x = -3
x = -3/20
x = -0.15
B 15% if you divide 100/20 you get 5 what is 5x3 15
I dont know if this is right but from my background knowledge you can tell that a fraction corresponds with a repeating decimal because it’s repeating the same numbers over and over and a terminating decimal would end.
Answer:
65 mph
Step-by-step explanation:
To find the unit rate (miles per hour), we can use the equation
Where
r=rate (miles per hour)
d=distance (in miles)
t=time (in hours)
Using the given information, we can plug in
So, our equation is
When we divide 97.5 and 1.5, we get
So,
In conclusion, the rate (miles per hour) is 65 mph.
