Answer:
<em>- 2 </em><em> + 7x²y - 24y² </em>
Step-by-step explanation:
( 5 - 5x²y + 9y² ) - ( 7
- 12x²y + 33y² ) =
5 - 5x²y + 9y² - 7
+ 12x²y - 33y² =
( 5 - 7
) + ( - 5x²y + 12x²y ) + ( 9y² - 33y² ) =
<em>- 2 </em><em> + 7x²y - 24y²</em>
Percent increase from 2000 to 2001 is 12% and from 2001 to 2002 is 12.6%. Thus period of 2001 to 2002 has higher increase percentage.
Solution:
Given that,
Total circulation of local newspaper in 2000 = 3250
Total circulation of local newspaper in 2001 = 3640
Total circulation of local newspaper in 2002 = 4100
As we can see 12% < 12.6%
So period of 2001 to 2002 has higher increase percentage.
Answer:
Height= 4m (nearest meter)
Step-by-step explanation:
Diameter= 2(radius)
Given that the diameter is 12m,
radius of cone
= 12 ÷2
= 6m
Let the height of the cone be h meters.
h= 4.0054 (5 s.f.)
Thus, the height of the cone is 4m. (nearest meter)
