Answer:

The nth term of the given sequence is given by  a(n)  = -3(1  + n)

Step-by-step explanation:

The given  AP sequence is  -6, -9, -12, -15, ...

Here, the first term = -6

The common difference (d) = a 2  - a 1  

= -9  - (-6)  = -9  + 6  

= -3

⇒ d  = - 3

Now, nth term of the Arithmetic Sequence is  a_n  = a+ (n-1)d

⇒ a(n)  = -6 + (n-1) (-3)

= -6   -3n + 3

= -3 - 3n

or, a(n)  = -3(1  + n)

Hence, the nth term of the given sequence is given by  a(n)  = -3(1  + n)

Answer:

  • 9x⁵

Step-by-step explanation:

<u>Use properties of exponents:</u>

  • <u />a^{b} a^{c} = a^{b+c}, (a^{b} ^)^{c} = a^{bc}, 1/a^{-b}  = a^{b}

<u>Simplify the given expression:</u>

  • 3⁴⋅x⋅(3/x²)⁻² =
  • 3⁴·x·(3x⁻²)⁻² =
  • 3⁴·x·(3⁻²)(x⁻²ˣ⁻²) =
  • 3⁴⁻²·x¹⁺4 =
  • 3²·x⁵ =
  • 9x⁵

Given a medicine provides 3.6 milligrams of medicine. Therefore, the amount of medicine the dog will have in a week is,

The amount of medicine = 3.6milligrams × 7 = 25.2 milligrams
