You have to use the midpoint formula, which is (x1+x2/2, y1+y2/2)

1. Plug in the coordinates

((-3 + 5)/2, (17 + 2)/2)

2. Solve the equation

(2/2, 19/2)

Center of the circle: (1, 9.5)

Someone please help me on both the questions!!!

bonufazy [111]

Step-by-step explanation:

al nth term:

numerator:

$= {n}^{2}$

denominator:

$= n + 1$

so nth term :

$= \frac{ {n}^{2} }{n + 1}$

b). 1; 11; 27; 49

first difference: 10; 16; 22

second difference :6

formula for 1st difference:3a+b

formula for 2nd difference:2a

Therefore:

2a=6

a=3

3a+b=10

sub in a

3(3)+b=10

9+b=10

b=1

sub into quadratic formula

${an}^{2} + bn + c$

$(3) {(1)}^{2} + (1)(1) + c = 1$

$3(1) + 1 + c = 1$

$3 + 1 + c = 1$

$4 + c = 1$

$c = - 3$

So Tn:

$3 {n }^{2} + 1n - 3$

in isoscles triangles two angles and lengths are equal .

two sides equal 3.5

so both of the angles are 55°

the sum of the angles in a triangle is 180°, so

x = 180° - 55° - 55°
