Find an equation for the nth term of the arithmetic sequence. <br><br> -20, -16, -12, -8, .

quester [9]

A n =?
If the arithmetic sequence is:-20, - 16, - 12 , - 8 ...
a 1 = -20, d = 4 ( a 2 = -20 + 4 = -16, a 3 = -16+4 = -12,...)
And the formula for nth term is:
a n = a 1 + d (n -1)
a n = -20 + 4( n -1) (n=1.2.3...)

A line passes through (-7,-5) and (-5,4). Write an equation for the line in point-slope form. Rewrite the equation in standard f

pashok25 [27]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ -7 &,& -5~) 
% (c,d)
&&(~ -5 &,& 4~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{4-(-5)}{-5-(-7)}\implies \cfrac{4+5}{-5+7}\implies \cfrac{9}{2}$

$\bf \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-5)=\cfrac{9}{2}[x-(-7)]
\\\\\\
y+5=\cfrac{9}{2}(x+7)\impliedby \textit{now let's multiply both sides by }\stackrel{LCD}{2}
\\\\\\
2(y+5)=2\left[ \cfrac{9}{2}(x+7)\right]\implies 2y+10=9(x+7)
\\\\\\
2y+10=9x+63\implies \stackrel{standard~form}{-9x+2y=53}$

If m <1=30 and m ST = 20, then m VU

grin007 [14]

Answer: 80°

Step-by-step explanation:

Since, If two secants intersect outside the circle, then the measure of the angle formed is one half of the difference of the measures of the intercepted arcs.

In the given diagram,

Chord VS and chord UT are intersecting externally,

Also, ∠SPT is the angle formed by the intersection of these chords.

Thus, by the above property,

$\frac{1}{2}[m(\widehat{VU})-m(\widehat{ST})]=m\angle SPT$
