Answer:
9672
Step-by-step explanation:
Population growth can be represented by the equation . We know the rate at which it grows is 1.36%. For the formula, we use the decimal conversion which is r=0.0136. We find the amount of time that has passed between 200 and 2006 is t=6 years. In this context, the starting population is . We substitute and solve for A.
We solve with a calculator by evaluating the exponent first and then multiplying by 8914.
.
The solution is 9671.88356154 but we round to 9672.
Answer:

Step-by-step explanation:
Answer: The formula for the area A is
4t^2 + 56t + 160
Step-by-step explanation: Please see the attached diagram.
Figure ABCD shows the 20 cm by 8cm print. Then the surrounding frame which is shown in the diagram as EFGH has dimensions as t. That is, either side (length or width) measures t cm away from the edge of the picture frame. Therefore to compute the total area of the entire figure, which includes both picture and frame, we would have to add up t cm to the known dimensions. Hence the length of the entire figure would be 20 + t + t (which gives us 20 + 2t) and the width would be 8 + t + t (which would give us 8 + 2t).
Therefore if the length and width have been derived as above, the area of the entire figure can now be calculated as;
Area = (20 + 2t) x (8 + 2t)
By expanding the bracket we have
Area = 160 + 40t + 16t + 4t^2
By collecting like terms we now have
Area = 160 + 56t + 4t^2
Therefore
A = 4t^2 + 56t + 160
Answer:
Step-by-step explanation:
-2x + 4 = 12
Subtract 4 from both sides of the equation
-2x = 8
Divide both sides of the equation by 2
-x = 4
Transfer the minus (multiply both sides by -1)
Hope this helps :)
