A historian took a count of the number of people in a Gold Rush town for six years in the 1870's Year
1871
1872
1873
1874
Population
480
494

1875

Find a quadratic function that models the data as a function of x, the number of years since 1870. Use the model to estimate the number of
people in the town in 1878
O a. P(x) - -3x? - 21x + 430; 136 people
b. P(x) - -7° + 21x + 480; 284 people
OC. P(x) = -3x? - 21x + 430; 70 people
O d. P(x) - -7° + 21x + 480, 200 people

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
