Please help with geometric mean!!

The exact value of y is 4\sqrt{3}.

Solution:

The attached below shows how the formula is written.

Using geometric mean,

Total base length (p + q) = 8

q = 6

p = 8 – 6 = 2

Let us first find the height of the triangle.

h^2=pq

h^2=2\times6

h^2=12

Taking square root on both sides,

h=\sqrt{12}

Using Pythagoras theorem,

<em>In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.</em>

y^2=(\sqrt{12})^2+6^2

y^2=12+36

y^2=48

y=4\sqrt{3}

The exact value of y is 4\sqrt{3}.

Use logarithmic differentiation to find the derivative of the function.y = x^8 sin(x)
givi [52]

Answer: \frac{\partial y}{\partial x}=8x^{8sinx}(cosx.logx+\frac{sinx}{x})

Step-by-step explanation:

Since we have given that

y=x^{8sinx}

By using logarithmic on both sides we get,

log y= 8 sinx. logx

(∵ log(a^m)=m.loga)

Now, differentiating on both sides ,we get,

\frac{1}{y}.\frac{\partial y}{\partial x}=8(\frac{\partial sinx}{\partial x}.logx+sinx \frac{\partial logx}{\partial x})

\\\frac{1}{y}\frac{\partial y}{\partial x}=8(cosx.logx+sinx.\frac{1}{x})

\\\frac{\partial y}{\partial y}=8y(cosx.logx+\frac{sinx}{x})\\\\\frac{\partial y}{\partial x}=8x^{8sinx}(cosx.logx+\frac{sinx}{x})

The proportion of observations from a standard normal distribution that take values greater than 1.36 is:
matrenka [14]

Answer:

We are required to find the proportion of observations from a normal distribution that are greater than 1.36. Mathematically, it can be written as:

P(z>1.36)

To find this proportion, we can use the standard normal table. Using the standard normal table, we have:

P(z>1.36)=0.0869

Therefore, the proportion of observations from a standard normal distribution that take values greater than 1.36 is 0.0869.
