The sum of the first 150 negative integers is represented using the expression What is the sum of the first 150 negative integer
Kamila [148]

Answer:

C. -11,325

Step-by-step explanation:

  • To know the answer, is convenient to replace some values of "n" in the sum \sum_{(n=1)}^{150}[-1-(n-1)].
  • The result would appear after adding up every value of the expression \sum_{(n=1)}^{150}[-1-(n-1)] when n=1,2,3.....,150.
  • When n=1, the expression takes the value of (-1): [-1-(1-1)]= (-1)-0=-1.
  • When n=2, the expression takes the value of (-2): [-1-(2-1)]=-1-1=-2.
  • Following this way, for every n, we will obtain -n, then, the sum will be: -1-2-3-4-5-6-...-150. This sum can actually be expressed as \sum_{n=1}^{150}(-n), which is the result of solving the initial expression of the sum -1-(n-1)=-1-n+1=-n.
  • Finally, the sum of n=-1 to n=-150 equals -11,325.

Pn= 40(1.156n) what is the initial population of slugs
charle [14.2K]

Answer:

The initial populations of slugs is 40

Step-by-step explanation:

we have

P(n)=40(1.156^{n})

This is a exponential function of the form

f(x)=a(b^{x})

where

a is the initial value (value of f(x) when the value of x is equal to zero)

b is the base

r is the rate

b=(1+r)

In this problem we have

a=40\\b=1.156\\r=b-1=1.156-1=0.156=15.6\%

therefore

The initial populations of slugs is 40

<u><em>Verify</em></u>

For n=0

substitute in the function

P(0)=40(1.156^{0})

P(0)=40(1)

P(0)=40\ slugs
