Just like 2 squared = 4, the square root of 2 multiplied by itself will result in a product of 2. Squaring a number always means multiplying that number by the same number.

In percent of change what is 27 to 36 plz help
Novay_Z [31]
If your "original" number is 27, this is the work:
percent change = change/original * 100
percent change = (36-27)/27 * 100
percent change = 9/27 * 100
percent change = 1/3 * 100
percent change = 33 1/3

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

Ben thinks that the largest place value that 5.6 and 1.78 have in common is the tenths place. Nichole thinks that the largest pl
-Dominant- [34]

The place values in 5.6 and 1.78 are the positions of the digits in the numbers

  • The largest place value common in 5.6 and 1.78 is the ones place
  • Nichole is correct

<h3>How to determine who is correct?</h3>

In a number, the non-zero digit at the left-most position is the greatest place value

This means that:

The greatest place value in 5.6 is 5 (i.e. ones place)

The greatest place value in 1.78 is 1 (i.e. ones place)

So, we can conclude that the largest place value common in 5.6 and 1.78 is the ones place

Hence, Nichole is correct

Write an explicit formula that represents the sequence defined by the following recursive formula
Stels [109]

Answer:

The explicit formula is a_{n} = 5 - 6n

Step-by-step explanation:

The explicit formula of the arithmetic sequence of the recursive formula

a_{1} = first term; a_{n} = a_{n-1} + d is a_{n} = a + (n - 1)d, where

  • a is the first term
  • d is the common difference between each two consecutive terms
  • n is the position of the number

∵ The recursive formula is a_{1} = -1 and a_{n} = a_{n-1} - 6

→ Compare it with the formula above

∴ a = -1 ⇒ 1st term

∴ d = -6 ⇒ common difference

→ Substitute them in the form of the explicit formula

∵ a_{n}  = -1 + (n - 1)(-6)

∴ a_{n} = -1 + (-6)(n) - (-6)(1)

∴ a_{n}  = -1 + -6n - (-6)

∴ a_{n} = -1 - 6n + 6

→ Add the like term

∴ a_{n} = 5 - 6n

∴ The explicit formula is a_{n} = 5 - 6n
