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 solution is
(2,1)
So the value of the x-coordinate is 2

Answer:
B.) 191.1 cubic cm.
Step-by-step explanation:
First find the area of the rectangular prism. Because the formula is l * w * h, this becomes
= 149.1.
For the volume of a pyramid, the equation is
. We already know the height, and because it's sitting on top of the rectangular prism, the base should have the same area. In other words, if the prism has a base of 7*6, then the pyramid can be found through
. 7 Multiplied by 6 is 42, and since it's multiplied but also divided by 3, they cancel out, leaving only 42.
The sum of both of these shapes is 191.1 cm³.
