Answer:
from questions it is given that X is lies between the -9 and -5. In this question X lies only between -9 to -5 but -9 and -5 are excluded because there is no equal sign given in the question. so value of X are (-8,-7,-6). and plot in the graph .and these values are the component of X so they are also a domain.
Answer:
1) 
2) 
3) 
4) 
Step-by-step explanation:
1) Value of 
since sin45° = 1/√2
Therefore
2).Value of 
Since cos 30° = √3/2
Therefore
3). Value of 
since tan 60° = √3
therefore
4). Value of 
Since sin90°=1
Therefore
Answer:
k=9
Step-by-step explanation:
First find r=22/20=1.1
The sum of the first k terms formula is a1•(1-r^k)/(1-r)
a1=20 and the sum is 271.59
Now plug in these values in the formula and find k.
271.59=20(1-1.1^k)/(1-1.1)
When you simplify this equation, you will get k=ln(2.358)/ln(1.1)
k=9
Length x Width x height
14•10•10= 1400
Wouldn’t the answer be 40 be cause you multiply?
