In ΔXYZ, ∠X=82° and ∠Y=84°. ∠XWZ=90° and XY=97. Find the length of XW to the nearest integer.

ivanzaharov [21]

Check the picture below to the left, let's use those sides with the law of sines

$\textit{Law of sines} \\\\ \cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{sin(14^o)}{97}=\cfrac{sin(84^o)}{XZ}\implies XZ = \cfrac{97\cdot sin(84^o)}{sin(14^o)}\implies XZ \approx 398.76 \\\\\\ \stackrel{\textit{now using SOH CAH TOA}}{cos(82^o) = \cfrac{XW}{XZ}}\implies XZcos(82^o)=XW \\\\\\ 398.76cos(82^o)\approx XW\implies 55.497\approx XW\implies \stackrel{\textit{rounded up}}{55=XW}$

The Baker formula estimates the maximum heart rate, in beats per minute, of a person who is

seropon [69]

Answer:

For a=16, the Maximum Heart Rate is 188 Beats Per Minute.

Step-by-step explanation:

<em>To begin, we know that the formula:</em>

$b(a)=200-0.75a$ Eqn(1).

<u>is equivalent to a linear equation of algebraic form denoted as:</u>

$y=k+mx$ Eqn(2)

<em>as such that Eqns (1) and (2) relate as follow:</em>

$y$ ⇔ $b(a)$ : denoting our Dependent Variable, in this case <em>Max. Heart Rate in Beats Per Minute</em>

$x$ ⇔ $a$ : is our Independent Variable<em>, </em>in this case the <em>Age of the Person</em>

$m$ ⇔ $0.75$ : denoting the<em> Rate of Change of the Age.</em>

$k$ ⇔ $200$ : denoting our <em>Constant.</em>

Now in the question our value of $b(a)$ is given as 188 beats per minute, which by plugging in Eqn(1) gives:

$200-0.75a=188$

from which we can solve to obtain the value of $a$ as follow:

$-0.75a=188-200$ Gather similar terms on each side

$-0.75a=-12\\$ Simplify

$a=\frac{-12}{-0.75}$ Solve for $a$

$a=16$

Which tells us that at the Age of 16, the Max. Heart Rate is 188 Beats Per Minute.

Consider the sequence following a minus 8 pattern: 9, 1, −7, −15, ….

photoshop1234 [79]

Answer: -287

Step-by-step explanation:

The given pattern: 9, 1, -7, -15, ….

We observe that ,

First term : a=9

Common difference between the terms= 1-9=-8

For Arithmetic sequence , the formula to find the nth term is given by :-

$a_n=a+(n-1)d$

Then, 38th term will be :-

$a_{38}=9+(-8)(38-1)\\\\=9-8(37)=9-296=-287$

Hence, the 38th term of the sequence.= -287
