A side of the triangle below has been extended to form an exterior angle of 74°. Find the value of x.​

Answer:

 [tex]cos(sin^{-1} (\frac{16}{20} )[/tex] = 0.60

Step-by-step explanation:

Explanation

Given that the trigonometric function

                [tex]cos(sin^{-1} (\frac{16}{20} )[/tex]

          = [tex]cos(sin^{-1} (0.8 )[/tex]

         = [tex]cos(53.13010)[/tex]

        = 0.60

Answer: x=2 and y=−1

Step-by-step explanation:

5x+7y=3for x:

5x+7y=3

5x+7y+−7y=3+−7y(Add -7y to both sides)

5x=−7y+3

x= −7/ 5 y+ 3 /5

Substitute −7 /5 y+ 3 /5  for x in2x+3y=1:

2( −7/ 5 y+ 3 /5 )+3y=1

1 /5 y+ 6 /5 =1(Simplify both sides of the equation)

1 /5 y= −1 /5

y=1

Substitute −1 for y in x

−7 /5 y+ 3 /5 : x=

x=2

x=2(Simplify both sides of the equation)

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

The function that is the inverse of the exponential function y = 4^x is lnx/ln4

The 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

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

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]

Step-by-step explanation:

Distributive property means breaking up the factors and multiplying them separately

So here we have 2(-5+3) = 2(-5)+2(3) = (-10)+(6) = (-4)

So (-4) is the value.
