Answer:

h'(x) = (-x² ln x + x² + 1) / (x (x² + 1)^(³/₂))

Step-by-step explanation:

h(x) = ln x / √(x² + 1)

You can either use quotient rule, or you can rewrite using negative exponents and use product rule.

h(x) = (ln x) (x² + 1)^(-½)

h'(x) = (ln x) (-½) (x² + 1)^(-³/₂) (2x) + (1/x) (x² + 1)^(-½)

h'(x) = (-x ln x) (x² + 1)^(-³/₂) + (1/x) (x² + 1)^(-½)

h'(x) = (x² + 1)^(-³/₂) (-x ln x + (1/x) (x² + 1))

h'(x) = (1/x) (x² + 1)^(-³/₂) (-x² ln x + x² + 1)

h'(x) = (-x² ln x + x² + 1) / (x (x² + 1)^(³/₂))

Answer:

obtuse

Step-by-step explanation:

if one angle is 25 and the other 50, then the third angle is 105, because all three angles have to add up to 180. So it is a obtuse triangle.

Kamila [148]
The confidence interval is from 9.81 to 10.19.

We first find the mean of the data:

<span>(9.8+10.2+10.4+9.8+10.0+10.2+9.6)/7 = 10

Next we find the standard deviation:
</span>σ=√([<span>(9.8-10)^2+(10.2-10)^2+(10.4-10)^2+(9.8-10)^2+(10-10)^2+(10.2-10)^2+(9.6-10)^2]/7) = 0.262

The z-score for 95% confidence is found by
1-0.95 = 0.05; 0.05/2 = 0.025; from the z-table, it is 1.96.

The confidence interval is calculated using
</span>x\pm z\times (\frac{s}{\sqrt{n}})&#10;\\&#10;\\10 \pm 1.96(\frac{0.262}{\sqrt{7}})=10\pm 0.1941<span>
