Answer:
The percentage increase in bird population in the second years is 4% .
Step-by-step explanation:
Given as :
During two years, the population of birds of an island became 7 times more than before.
The the percentage increase in first year = =
=40%
Let The percentage increase in second year =
= r%
So, According to question
The initial population of bird = x
The increase population of bird =7 times before = 7 x
Now,
The increase population of bird = initial population of bird × (1+
) × (1+
)
Or, 7 x = x × (1+
) × (1+
)
Or,
= 1.4 × (1+
)
Or, 7 = 1.4 × (1+
)
Or,
= (1+
)
Or, 5 = (1+
)
Or, (1+
) = 5
Or,
= 5 - 1
Or,
= 4
∴ r = 4 × 100
I.e r = 400
so, The percentage increase = r% = 4
Hence The percentage increase in bird population in the second years is 4% . Answer
7/9 is the answer because you have to find common denominators and all that
Initially, milk needed = 3 3/4 = 15/4
If it doubles, 15/4 * 2 = 30/4 = 15/2 in fraction form
OR 7.5 in decimal form
OR 7 1/2 in mixed form
Answer:
The domain that makes sense for this function is all values greater than or equal to 0.
Step-by-step explanation:
A ball is thrown into the air from a height of 4 feet at time <em>t</em> = 0. It is modeled by the function:

The domain of the function is time <em>t</em>. The range of the function is the ball's height in the air <em>h</em>.
Since time is our domain, we must restrict our domain to values equal to or greater than 0 since time cannot be negative.
Therefore, the domain that makes sense for this function is all values greater than or equal to 0.
In interval notation, this is:

And as an inequality:

Step-by-step explanation:
Area of the circle=

3.14•(17)²/4
=226.865in²
Area of the rectangle=length•width
=(8•15)in²
=120in²
Area of the shaded portion=Area of the circle-Area of a rectangle
=(226.865-120)in²
=106.865in²
=106.87in² to the nearest hundredth
