Use the geometric mean theorems to find AC and BD. BA=20 BC=15

Mathematics
1 answer:
kiruha [24]3 years ago
7 0

Step-by-step explanation:

first, you use the pythagorean theorem to find the missing side of the original and big triangle.

20 {}^{2}   +  15 {}^{2}

next, you simplify these into actual numbers

400 + 225

after, you add these numbers together and find the square root.

\sqrt{625}  = 25

you have the answer for <em>AC</em><em>.</em><em> </em>next you need to find <em>BD</em><em>.</em><em> </em>of you line up <em>BC</em><em> </em>with <em>BD</em><em>,</em><em> </em><em>BC</em><em> </em>would be longer, , so you know its shorter, but not by much, so I'd assume to guess like 13 for <em>BD-</em><em> </em>that's just me- but I'm not sure how to exactly find it.

Find the derivative of f(x)=2arcsin(x-1)
andreev551 [17]
Since \dfrac{\mathrm d}{\mathrm dx}\arcsin x=\dfrac1{\sqrt{1-x^2}, you have

\displaystyle\frac{\mathrm d}{\mathrm dx}2\arcsin(x-1)=2\frac{\mathrm d}{\mathrm dx}\arcsin(x-1)=2\frac{\dfrac{\mathrm d}{\mathrm dx}(x-1)}{\sqrt{1-(x-1)^2}=\frac2{\sqrt{2x-x^2}}
