An archeologist used the functions below to model the changing populations of two ancient cities as they grew in size. Compare t

Lyrx [107]

Answer:

The answer is "6.3 and 5.25"

Step-by-step explanation:

Please find the complete question in the attached file.

Throghout the question the calculated points are:

$(0,0) , \ \ (40,252) \\(0,0) , \ \ (40,210) \\$

Formula for Calculating slope:

$M=\frac{y_2-y_1}{x_2-x_1}$

For First point slope:

$M=\frac{252-0}{40-0}=\frac{252}{40}= 6.3 \ \frac{people}{mi^2}$

For second point slope: $M=\frac{210-0}{40-0}=\frac{210}{40}=\frac{21}{4}= 5.25 \ \frac{people}{mi^2}$

Sierra found that 15 meters is equivalent to 49.2 feet. Which of the following is an equivalent ratio?

madam [21]

Answer:

7 to 22.96

Step-by-step explanation:

Hello!

We can represent each ratio as a fraction:

Original: 15 to 49.2 = $\frac{15}{49.2}$
3 to 8.84 = $\frac{3}{8.84}$
5 to 18.22 = $\frac{5}{18.22}$
7 to 22.96 = $\frac{7}{22.96}$
9 to 25.32 = $\frac{9}{25.32}$

To find equivalent values, we can convert each fraction into a decimal by dividing them.

<h3>Convert</h3>

Original: $\frac{15}{49.2} = 0.304878048780488$
$\frac{3}{8.84} = 0.339366515837104$
$\frac{5}{18.22} = 0.274423710208562$
$\frac{7}{22.96} = 0.304878048780488$
$\frac{9}{25.32} = 0.355450236966825$

The ratio of 7 to 22.96 is equivalent to the ratio of 15 to 49.2.

Given the function:

SashulF [63]

Answer:

±1/5, ±2/5, ±3/5, ±1, ±6/5, ±2, ±3, ±6

Step-by-step explanation:

The rational root theorem tells you possible rational roots are ...

... ±(divisor of the constant term) / (divisor of the highest-degree term coefficient)

The constant term, -6, has divisors ±1, ±2, ±3, ±6. The coefficient of the highest degree term, 5, has divisors ±1, ±5. Possible ratios of these values are listed above.

_____

<em>Roots of this Function</em>

The coefficients sum to zero, so x=1 is a root. Factoring out (x-1) leaves a factor of 5x² +13x +6, which can be factored as (x+2)(5x+3). Hence the roots are -2, -3/5, +1 — all on the list of possible rational roots.
