Answer:
<em>about 9765 mosquitoes</em>
<em />
Step-by-step explanation:
This is an exponential growth problem which follows the formula:
Where A is the future amount (we need this after 4 months)
P is the initial amount (here, it is 4000)
r is the rate of increase (here it is 25% or 0.25)
t is the time period (here t= 4, because we want to know after 4 months)
<em>plugging in all the available/given info, we can solve for A:</em>
<em>
</em>
<em />
<em>Since, no fractional mosquitoes, we round down to </em><em>9765 mosquitoes</em>
Answer : The average rate of change between 1 year and 4 years of age is 7.33 lbs per year.
Step-by-step explanation :
As we know that the average rate of change between two input values is the total change of the output values divided by the change in the input values.
From the table, we conclude that:
The weight of 1 year of age = 20 lbs
The weight of 4 years of age = 42 lbs
Now we have to determine the average rate of change between 1 year and 4 years of age.
The input (years) has changed by = 4 years - 1 year = 3 years
The output has changed by = 42 lbs - 20 lbs = 22 lbs
Average rate of change = Output ÷ Input
Average rate of change = 
Average rate of change = 7.33 lbs per year
Therefore, the average rate of change between 1 year and 4 years of age is 7.33 lbs per year.
Answer:
Rs 175
Step-by-step explanation:
Suppose the cost is x and at Rs150 the loss is 150-x (this should be a negative number).
At Rs200, the profit is 200-x.
So we have an equation: minus 150 minus x is equal to 200 minus x.
To solve the equation, the cost price X is Rs175.
Answer:
the correct answer is (x,y) (3,-2)
