Answer:
Step-by-step explanation:
<u>Exponential function is:</u>
<u>If we consider the time difference in years as x and the initial population as a, then we get:</u>
<u>Find the value of b:</u>
- b¹⁰ = 675647/617594
- b¹⁰ = 1.09399864636
- b = 1.09399864636^(1/10)
- b = 1.009 (rounded)
<u>The equation we got is:</u>
Here we have y- population after x years since 2010, x - the number of years since 2010 and 1.009 is the population growth rate.
The correct answer for this would be the last option. The factors of 48m - 80n are 16(3m - 5n). If you try to solve this, the result would be 48m - 80n. 16 x 3m would be 48m and 16 times 5n would be 80n. Hope this is the answer that you are looking for.
I think it’s 48 but are those the only answer choices???
So we know the equation to find the volume of a cylinder is
Volume of cylinder = πr^2<span>h
where r is radius and h is height.
For the bottle of lotion, we are given a radius of 3cm and a height of of 12cm.
Sub these numbers into the equation:
</span>Volume of bottle = 3.14*3^2*12
Therefore we get 339.12cm^3
For the tube in the bottle, w<span>e are given a radius of 0.5cm and a height of of 12cm.
</span><span>Sub these numbers into the equation:
</span>Volume of bottle = 3.14*0.5<span>^2*12
</span>Therefore we get 9.42cm^3
To find the volume of the lotion we have to take the total volume in the bottle by the volume in the tube.
=339.12 - <span>9.42
</span>=329.7cm^3
Note: Don't round your number earlier on, always round at the end but in this case the answer came exactly to one decimal places.
