Answer:
the blank number is 23
Step-by-step explanation:
8, 15, 27, x, 20
common ratio, r= T2÷ T1= T3÷ T2
= 15 ÷ 8 =27÷ 15
= 1.8 = 1.8
20 ÷ x = x ÷ 27
( cross multiply,)
x²= 540
x =√540
x = 23.24
x = 23
This can't be factored with rational numbers.
Answer:
-1/5
Step-by-step explanation:
(10 ,9) .....(40 , 3)
(9-3)/(10-40)=6/-30=-1/5
The answer to it is 119
since 50% of the number is 170 just multiply 170 by 2 to get 340, then find 35% of 340. 10% of 340 is 34, multiply 34 by 3.5 to get 119.
Answer:
Closed and Bounded.
Step-by-step explanation:
Hi there!
1) Let's start by finding the values in which the function is defined. Remember that this can be rewritten:

Since every quadratic root are defined for values
0 then, this help us to understand that we need calculate what interval this Domain is:

![D=[-2,2]](https://tex.z-dn.net/?f=D%3D%5B-2%2C2%5D)
2) Graphically speaking, the domain is closed. For the values -2 and 2 are included, and bounded.
Bounded functions have all of their points contained by some circle origin centered. Check it out below.
