A species of horned beetle has a (starting) population size of 4000 individuals. Every month, 170 individuals are born. However,

you cannot assess the number of individuals that die every month because after death the animals are susceptible to a fungus that quickly degrades their carcasses. You can measure, though, that the population is declining over time, with the population size decreasing by 70 individuals every month (i.e. dN/dt). Calculate a) the total number of deaths per month (1pt) and the per capita death rate (

Answer:

Please refer to the explanation

Step-by-step explanation:

Provided parameters:

Initial population = 4000

Monthly increase = 170

Monthly decline in population = 70

Monthly growth rate in population (dt):

Starting population = 4000

Births per month = 170

However, there is a loss of 70 individuals monthly

Thus,

Births - Deaths (d) = 70

170 - d = - 70 (is there a decline?

170 + 70 = d

d equals the number of deaths

Per capita death rate:

Total deaths monthly / Initial population

= 240 / 4000

= 0.06

In the Ma-and-Pa grocery store, shelf-space is limited and must be used effectively to increase profit. Two-cereal items, Grano
Inessa [12570]
No. Allocate 2/3 of the space to Grano and 1/3 to Wheatie. This results in approximately 57% for Wheatie and 43% for Grano—meaning 60(.57)=34.2 ft² for Wheatie and 60(.43)=25.8 ft² for Grano. Therefore, there would be about 85.5 boxes of Wheatie and 129 boxes of Grano, leading to a total profit of 129(1)+85(1.35)=$243.75. The best choice would be to place 200 boxes of Grano and 50 boxes of Wheaties on the shelf. Allocating 40 ft² to Granos (200(.2)) and 20 ft² to Wheaties (50(.4)) means that 40/60=2/3=66.6% of the space would be for Granos, and 20/60=1/3=33.3% would be for Wheaties. The total profit would be 200(1)+50(1.35)=$267.5.

A quadratic function has a line of symmetry at x = –3.5 and a zero at –9. What is the distance from the given zero to the line o
Svet_ta [12734]

Given:

A quadratic function has a line of symmetry positioned at x = –3.5 with one root located at –9.

To find:

The second root.

Solution:

It is understood that the line of symmetry splits the quadratic function's graph into two identical halves. Hence, both roots are equidistant from this line.

This implies that the line of symmetry passes through the midpoint of the two roots.

Let the other root be denoted as x.

-3.5=\dfrac{(-9)+x}{2}

Multiply both sides by 2.

-7=-9+x

Add 9 to both sides.

-7+9=-9+x+9

2=x

Consequently, the other zero of the quadratic function is concluded to be 2.
