Answer:
r≈5.64
Step-by-step explanation:
Answer:
v= 7*6/2 *8 (The last one)
Step-by-step explanation:
To find the volume you have to multiply the base and the height which is 7 and 6 and divide it by 2. Then you multiply the 8.
Answer:
False
True
False
False
Step-by-step explanation:
1. We have to get the sum as follows :

= 
= 
= 
= 
So, this is false.
2. We have to get the sum as follows :

= 
= 
= 
= 
So, this is true.
3. We have to get the difference as follows :

= 
= 
= 
= 
So, this is false.
4. We have to get the difference as follows :

= 
= 
= 
= 
So, this is also false. (Answer)
A) x ≈ 9.3 or x≈ -6.3
B) x ≈ 3.2 or x ≈ -4.7
C) x ≈ 6.4 or x ≈ -9.4
The answer is B
Domain: Set of all real numbers
Range:

where y is a real number
---------------------------------------------------
The domain is the set of real numbers because there are no restrictions on what to plug in for x. There are no gaps, holes, jumps, or asymptotes. The graph continues on in both directions stretching to both infinities (this is indicated by the arrows on the curve ends)
The range is the set of y values between -1 and 1 because this is the set of y outputs. The largest y can get is +1 or just 1. The smallest y can get is -1. The value of y can be any number in between as there are no gaps. <span />
