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.
