Answer:
= -
Step-by-step explanation:
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
here a = 14 and r = = - , hence
= 14 × = 14 × - = -
A chord is a line segment that goes from one side of the circle to the other without crossing the center.
Answer:
Step 1: x^2 + 8x + 15 + 1 = 0 + 1
Step 2: x^2 + 8x + 16 = 1
Step 3: (x + 4)^2 = 1
Step-by-step explanation:
You want the constant on the left to be the square of half the x-coefficient.
(8/2)^2 = 4^2 = 16
You already have a constant that is 15, so you need to add 1 to both sides of the equation. That is the <em>Step 1</em> shown here. <em>Step 2</em> is simplifying the result of <em>Step 1</em>. <em>Step 3</em> is rewriting the trinomial as the square of a binomial.
UW; Converse of the Isosceles Triangle Theorem
This is the answer because angles T and W are congruent. Meaning that they make an isosceles triangle. The two sides connecting to those angles should be congruent. Therefore UT and UW are congruent.
