Sec s = 1.6948
Anastaziya [24]
That'd be true only if the value of "s" is the exact same one for both
namely  if sec(s) = cos(s)
then solving for "s"
thus

\bf sec(s)=cos(s)\qquad but\implies sec(\theta)=\cfrac{1}{cos(\theta)}&#10;\\\\\\&#10;thus\cfrac{1}{cos(s)}=cos(s)\implies 1=cos^2(s)\implies \pm \sqrt{1}=cos(s)&#10;\\\\\\&#10;\pm 1=cos(s)\impliedby \textit{now taking }cos^{-1}\textit{ to both sides}&#10;\\\\\\&#10;cos^{-1}(\pm 1)=cos^{-1}[cos(s)]\implies cos^{-1}(\pm 1)=\measuredangle s

Triangle ABC had a perimeter 18 cm
Anna007 [38]

Answer:

Use pythagoreum theorem to determine whether it is or isn't since I'm not really sure myself but here's my calculations.

Step-by-step explanation:

We need to find AC.

Picture a triangle called ABC. AB is one side and BC the other while AC is the hypotenuse.

AC=

ac =  \sqrt{ab ^{2}  +  {bc}^{2} } \\ ac = \sqrt{ {7}^{2} }  +  {3}^{2}  \\ ac =  \sqrt{49 + 9}  \\ ac =  \sqrt{58 }  \\ ac = 7.6

Round up the 7.6 to a whole number and you get AC=8. To get perimeter of a triangle simply add the sides together to get 18.

Not really sure about my answer but hope this helped.

The sum of the first three terms of an arithmetic sequence is 108, and the sum of the next three terms is 183. what is the value
qaws [65]
The key is to find the first term a(1) and the difference d.

in an arithmetic sequence, the nth term is the first term +(n-1)d
the firs three terms: a(1), a(1)+d, a(1)+2d
the next three terms: a(1)+3d, a(1)+4d, a(1)+5d,
a(1) + a(1)+d +a(1)+2d=108
a(1)+3d + a(1)+4d + a(1)+5d=183

subtract the first equation from the second equation: 9d=75, d=75/9=25/3
Plug d=25/3 in the first equation to find a(1): a(1)=83/3

the 11th term is: a(1)+(25/3)(11-1)=83/3 +250/3=111

Please double check my calculation. <span />

Claire buys a jacket that originally cost $76. The price is marked down 25% for a sale, and Claire has a coupon to further reduc
Vika [28.1K]

Answer:

$51.30

Step-by-step explanation:

First, we find 25% of the original price, then we deduct that from the original price. Then, we find 10% of the price and deduct that also.

The original price is $76.

25% of $76 is:

\frac{25}{100} * 76 = $19

We deduct $19 from $76:

76 - 19 = $57

We find 10% of $57:

\frac{10}{100} * 57 = $5.7

Deducting this:

57 - 5.7 = $51.30

She will pay $51.30 for the jacket.
