Evaluate the indefinite integral. (Use C for the constant of integration.) sin(10x) 1 cos2(10x) dx
Answer:
The result of the integral is [tex]-\frac{\cos^3{10x}}{30} + C[/tex]
Step-by-step explanation:
We are given the following integral:
[tex]\int \sin{(10x)}\cos^{2}{(10x)} dx[/tex]
I am going to solve by substitution, using [tex]u = \cos{10x}[/tex], so [tex]du = -10\sin{10x}dx, dx = -\frac{du}{10\sin{10x}}[/tex]. So, we have
[tex]-\frac{1}{10} \int u^2 du[/tex]
Which has the following result:
[tex]-\frac{u^3}{30} + C[/tex]
Going back to x, the result of the integral is
[tex]-\frac{\cos^3{10x}}{30} + C[/tex]

find for x
Answer:
120°
Step-by-step explanation:
The angle next to the x will be 40° due to the alternate angles so
x + 40° + 20° = 180° { being linear pair }
x + 60° = 180°
x = 180° - 60°
x = 120 °
Hope it will help :)
Answer:
120˚
Step-by-step explanation:
Since the two lines are parallel, they are alternate angles
So that means that the angle next to x must be 40˚
So 40 + 20 + x = 180 (since it's half a circle)
60 + x = 180
x = 120

What function is the inverse of the exponential function y = 4^x?
The function that is the inverse of the exponential function y = 4^x is lnx/ln4
Exponential functionsThe standard exponential function is given as y = ab^x
Given the function
y = 4^x
Replace y with x
x = 4^y
Make y the subject of the formula
lnx = ln4^y
lnx = yln4
Divide both sides by ln4
lnx/ln4 = y
Hence the function that is the inverse of the exponential function y = 4^x is lnx/ln4

Pizazz manufactures a 5.0 oz. energy drink of the same name. Because the cans are so small, consumers are concerned that they are not receiving the full 5 ounces in each can. A quality engineer at the company is charged with analyzing the filling process and ensuring accurate readings. On 15 different occasions over the past month, she has taken a sample of 6 energy drinks off the production line and recorded their weight. The sum of the sample means is 80.20 ounces and the sum of the sample ranges is 12.68 ounces (Hint: You are already given the sum. You just have to find the x-double bar and R-bar).
Determine the control limits of an x-bar and R-chart. What is your conclusion?
Answer:
The LCL of the R-chart starts from the origin ( i.e. zero value ) while the LCL of an X -chart did not start from the origin
LCL of R-chart = 0 * 0.84533 = 0
LCL of R-chart = 75.128
Step-by-step explanation:
Given data:
number of observations = 15
sample size ( m ) = 6
sum of sample mean = 80.20 ounces
sum of sample range ( R ) = 12.68 ounces
Determine the control limits of an x-bar and R-chart
for an R-chart
LCL of R-chart = D3 * R(bar) ---- ( 1 )
where : m = 6 , D3 = 0 , R = 12.68
R(bar) = 0.84533
back to equation 1
LCL of R-chart = 0 * 0.84533 = 0
for an X-chart
LCL of X-bar) = ( mean ) - (m x R-bar)
= 80.20 - ( 6 * 0.84533 )
= 75.128
The LCL of the R-chart starts from the origin ( i.e. zero value ) while the LCL of an X -chart did not start from the origin
