Answer:
the population in 2015 is 8201.0695
Step-by-step explanation:
Given that
There is a population of the 50 timber wolves
And, the exponential function given is
p(t) = 50 × e^(0.85 × t)
Here t denotes the time period i.e.
= 2015 - 2009
= 6
So,
= 50 × e^(0.85 × 6)
= 8201.095
Hence, the population in 2015 is 8201.0695
Answer:
Answer is 12-19 = -7
Step-by-step explanation:
12- 19 you can break 19 into 12 +7
then
it is easy to find 12-12 = 0
Now subtracts 0 - 7 =- 7
then
break 7 into 3 + 4
then
0 - 3 = -3
-3 - 4 = -7
So ,
12 - 19 = -7
Answer:
the answer is b
Step-by-step explanation:
Hello :
cscx = -5/2
1/sinx =-5/2
sinx=-2/5
sin²x+cos²x=1
4/25+cos²x=25/25
cos²x = 21/25
between 270 and 360 : cosx > 0 cosx=(<span>√21)/5
but : sin2x =2sinx cosx
sin2x = 2(-2/5)(</span>(√21)/5)
sin2x = (-4√21)/25
Surface area of a cube = 486 square inches
Solution:
Given each side of a cube = 9 inches
Net of a cube has 6 squares.
Area of square = side × side
Area of 1 square = 9 × 9 = 81 square inches
Surface area of a cube = Area of 6 squares
= 6 × (side × side)
= 6 × 81
= 486 square inches
Hence, surface area of a cube is 486 square inches.
