Answer:

Step-by-step explanation:

Use sine and cosine.

$sine=\dfrac{opposite}{hypotenuse}$

$cosine=\dfrac{adjacent}{hypotenuse}$

Q8.

We have:

$opposite=y\\\\adjacent=x\\\\hypotenuse=18\\\\\alpha=18^o\\\\\sin18^o\approx0.309\\\\\cos18^o\approx0.9511$

Substitute:

$\dfrac{y}{18}=0.309$ <em> multiply both sides by 18</em>

$y=5.562\to y\approx5.6$

$\dfrac{x}{0.9511}=18$ <em>multiply both sides by 0.9511</em>

$x=17.1198\to x\approx17.1$

Q9.

We have:

$opposite=y\\\\adjacent=x\\\\hypotenuse=26\\\\\alpha=68^o\\\\\sin68^o\approx0.9272\\\\\cos68^o\approx0.3746$

Substitute:

$\dfrac{y}{26}=0.9272$ <em>multiply both sides by 26</em>

$y=24.1072\to y\approx24.1$

$\dfrac{x}{26}=0.3746$ <em>multiply both sides by 26</em>

$x=9.7396\to x\approx9.7$

Hello,
$\int\limits^h_0 {\frac{1}{2\pi} * e^{\frac{-(x-68)^2}{2}} dx}=0.4985
$
==>h=3*4=12
[68-12, 68+12] is the interval
