-9 
or
-9.25
Step-by-step explanation:
Answer:
x^2 + y^2 - 8x + 18y + 48 = 0
Step-by-step explanation:
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the centre of circle and r is the radius of circle. hence the standard form of equation can be obtained by expanding
(x-4)^2 + {y-(-9)}^2 = 7^2
Answer:
36 possible ways
Step-by-step explanation:
Range of digit : 0 up to 9
To obtain the number of strings of 4 decimal digits that have exactly 3 digits that are 9s ; we use the multiplication rule :
In other to have exactly 3 digits from 4 that are 9s :
Say:
We have 3 9s and the last number could be any of the 10 possible digits except 9
First 9 = 1 possible way (since we have only one 9 between (0 to 9)
Second 9 = 1 possible way
Third 9 = 1 possible way
4th digit = 9 ways (could be any digit between 0 and 9, except 9)
Also, we consider the 4th digit's position ; as it could take up any of different positions in between the 9s = 4 ways
Using the product rule :
1 * 1 * 1 * 9 * 4 = 36 possible ways
One third of the box will be 3 inches long, so is equivalent to a 3-inch cube. It has a volume of
... (3 in)³ = 27 in³
The appropriate choice is ...
... D. 27 cu. in.
_____
Volume is found by multiplying length by width by height. When all are the same (3 in), the product is (3 in)·(3 in)·(3 in) = (3 in)³.
Answer:
The size of the population of red squirrels in the UK at the start of 2010 is 3772
Step-by-step explanation:
At the start of 2016 , No. of squirrels = 10000
The rate of decrease is 15% per year.
So, No. of squirrels after x years = 
We are supposed to find the size of the population of red squirrels in the UK at the start of 2010.
So,No. of squirrels after 6 years = 
Hence the size of the population of red squirrels in the UK at the start of 2010 is 3772
