Using the Law of Cosines, in triangle DEF, if e=18yd, d=10yd, f=22yd, find measurement of angle D

Ivahew [28]

Check the picture below.

$\bf \textit{Law of Cosines}\\ \quad \\
c^2 = {{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)\implies 
c = \sqrt{{{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)}
\\\\\\
\cfrac{{{ a}}^2+{{ b}}^2-c^2}{2{{ a}}{{ b}}}=cos(C)\implies cos^{-1}\left(\cfrac{{{ a}}^2+{{ b}}^2-c^2}{2{{ a}}{{ b}}}\right)=\measuredangle C\\\\
-------------------------------\\\\
\begin{cases}
d=10\\
e=18\\
f=22
\end{cases}\implies cos^{-1}\left(\cfrac{{{ 18}}^2+{{ 22}}^2-10^2}{2(18)(22)}\right)=\measuredangle D$

$\bf \implies cos^{-1}\left(0.893\overline{93}\right)=\measuredangle D\implies 26.63^o\approx \measuredangle D$

Determine the second derivative evaluated at t=0

enyata [817]

If

$M(t) = e^{3(e^t-1)}$

then using the chain rule, we have

$M'(t) = e^{3(e^t-1)} \times 3e^t = 3e^{3(e^t-1)+t}$

$M''(t) = 3e^{3(e^t-1)+t} \times (3e^t+1)$

Then

$M''(0) = 3e^{3(e^0-1)+0} \times (3e^0+1) = 3e^0 \times (3+1) = \boxed{12}$

Original price: $29.99; Markdown; 33 and 1/3%

Jobisdone [24]

If your asking what the price of something is, that was originally 29.99, and has been marked down by 33.33%, the easy way to do this is to take 30 and multiply it by 1/3, resulting in 20. The proper way is to take your calculator and multiply 29.99 by 0.333, resulting in roughly 9.98, meaning the price you pay is 20.00. Either way, your still going to pay $20 for the item.

Which expression is equivalent to sqrt 8/x^6. assume x > 0

Naddik [55]

We have the following expression:
sqrt 8 / x ^ 6
Rewriting we have:
sqrt (8 / x ^ 6)
sqrt (2 * 4 / ((x ^ 2) * (x ^ 2) * (x ^ 2)))
(2 / (x * x * x)) sqrt (2)
(2 / x ^ 3) * sqrt (2)
Answer:
An equivalent expression is given by:
(2 / x ^ 3) * sqrt (2)
