4 0
For this case we have the following polynomial:
 -2x ^ 4 + 27x ^ 2 + 1200 = 0
 To solve the problem we apply the following steps:
 1) We make a change of variables u = x ^ 2
 2) We rewrite the polynomial
 3) Solve the quadratic equation using the formula for the quadratic equation
 4) We return the change and find four roots

Stolb23 [73]
In generation 8 it would have 34 relatives, and in generation 9 it would have 55 relatives.

In the Fibonacci sequence, each term is found by adding the two previous terms together.  For generation 8, we would add generation 7 (21) and generation 6 (13); 21+13 = 34.  For generation 9, we would add generation 8 (34) and generation 7 (21); 34 + 21 = 55.

Suppose a set of data about the spread (in hundreds of acres) of a food-borne bacteria (after t weeks) in lettuce has the follow
Alexxandr [17]

Answer:

A sinusoidal model would be used

The kind of function that have consistency in the periodic rate of change is the Average rate of changes

Step-by-step explanation:

The type of model that would be used is sinusoidal model and this is because there is periodic change in the values given ( i.e the rate of changes given )

For percentage rate of changes :

starting from 0.9% there is an increase to 1.3% then a decrease to 1.1% and a further decrease to 1% before an increase to 1.3% and another decrease to 1%

For Average rate of changes:

starting from 2.9 there is a decrease to 2.4, then an increase to 3.7 and another decrease to 3.1 followed by an increase to 3.6 and a decrease back to 3.2

This relation ( sinusoidal model ) is best suited for a linear model because there is a periodic rate of change in the functions

The kind of function that have consistency in the period rate of change is the Average rate of changes

Answer:

no you cant use these three ratios for any right triangle

Step-by-step explanation:

Ratios: 0.38, 0.93, 0.36

            I\

0.38    I    \  0.93        right triangle

            I        \

            I_____\

              0.36

so this means a^2 + b^2 = c^2 would be true if these ratio worked

(0.36)^2 + (0.38)^2 = (0.93)^2

0.1296 + 0.1444 = 0.8649             NOT TRUE
