Answer:

When y=7,9 the answer is yes when it = -10,-8 the answer is no.

Step-by-step explanation:

Simple substitution gets us the resulting values. for y=7 we get 15\geq 15 which is true. For y=9 we get 19\geq 15 which is also true. For the other values we get a negative number which is not a solution.

Which of these four sets of side lengths will form a right triangle?
Natalija [7]

Answer:

Set 4: 12 ft, 16 ft, 20 ft

Step-by-step explanation:

A right angle triangle is a triangle in which one of the angles is a right angle (i.e 90°). The side opposite to the right angle is the longest side and is called the hypotenuse. The Pythagoras theorem for a right angle triangle states the the square of the hypotenuse is equal to the sum of the square of the remaining two sides.

For set 1:

4² + 5² = 16 + 25 = 41

6² = 36

6² ≠ 4² + 5²

It does not form a right triangle

For set 2:

8² + 12² = 64 + 144 = 208

20² = 400

20² ≠ 8² + 12²

It does not form a right triangle

For set 3:

10² + 20² = 100 + 400 = 500

30² = 900

30² ≠ 10² + 20²

It does not form a right triangle

For set 3:

12² + 16² = 144 + 256 = 400

20² = 400

20² = 12² + 16²

It forms a right triangle

What are the geometric series of a1 and r of the geometric series?<br><br> 2-2+2-2+2
meriva

Answer:

a1=2 and r=-1

Step-by-step explanation:

Given

geometric series= 2-2+2-2+2

geometric sequence has a constant ratior r and is given by

an=a1r(r)^(n-1)

where

an=nth term

r=common ratio

n=number of term

a1=first term

In given series:

r= a(n+1)/an

 = a(2)/a1

 = -2/2

  =-1

so a1=2 and r=-1 !
