Find S5 for a geometric series for which a1=81 and r=1/9.
Minchanka [31]

ANSWER

S_5=91\frac{10}{81}




EXPLANATION


The sum of the first n terms of a geometric sequence is given by;


S_n=\frac{a_1(1-r^n)}{1-r} ,-1


Where n, is the number of terms and a_1 is the first term.


When n=5, we have a_1=81, we get;


S_5=\frac{81(1-(\frac{1}{9})^5)}{1-\frac{1}{9}}


S_5=\frac{81(1-\frac{1}{59049})}{1-\frac{1}{9}}


S_5=\frac{81(\frac{59048}{59049})}{\frac{8}{9}}




S_5=\frac{7381}{81}


S_5=91\frac{10}{81}

Select the correct answer. Two exterior angles of a triangle measure 135° and 100°. What are the measures of the interior angles
ozzi

Answer:

C

Step-by-step explanation:

interior angle + exterior angle are supplementary

interior angle = 180° - exterior angle

⇒ interior angle = 180° - 135° = 45°

and interior angle = 180° - 100° = 80°

The sum of the 3 angles in a triangle = 180°

To find the third interior angle, subtract the sum of the 2 interior angles from 180

third interior angle = 180° - (45 + 80 )° = 180° - 125° = 55°

interior angles are 45°, 55° and 80°
