Answer:
Number of statues that can be painted are 17
Step-by-step explanation:
Initially Diana has 
liters of paint remaining.
Every statue requires 
liters of paint for painting.
We have to find how many statues we will be able to paint with this remaining paint.
To get the number of statues,
Number of statues = 
number of statues = 
= 
= 17.5
Since the number of statues is not an integer the maximum number of statues that can be painted are 17.
Answer:

Step-by-step explanation:
A=bh/2.
A=(21*8)/2
A=168/2
A=84
Answer:
x = pi, 3pi, 5pi etc
x = -pi, -3pi, -5pi etc
Step-by-step explanation:
cos^2 x + 2 cos x + 1 = 0
replace cos x with m
m^2 + 2m +1 = 0
solve by factoring (this is a^2 +2ab+b^2 = (a+b)^2 where a =m and b=1)
(m+1)^2=0
take the square root of each side
m+1 =0
m=-1
now replace m with cos x
cos x = -1
take arccos of each side
arccos cos x = arccos (-1)
x = pi, 3pi, 5pi etc
Answer:
The missing value is 19.
Step-by-step explanation:
The equation is increasing by 2 and 17+2 equals 19.
Multiply everything by 4 so you get rid of the fraction
