Mathematics
1 answer:
scoundrel [369]2 years ago
7 0

Step-by-step explanation:

  • (3x-2y) (4x+3y) (8x-5y)
  • (3x(4x+3y)-2y(4x+3y))(8x-5y)
  • (12x²+9xy-8xy-6y²)(8x-5y)
  • (12x²+xy-6y²)(8x-5y)
  • 12x²(8x-5y)+xy(8x-5y)-6y²(8x-5y)
  • 96x³-60x²y+8x²y-5xy²-48xy²+30y³
  • 96x³-52x²y-53xy²+30y³

Which equation shows 4n=2(t-3) solves for t?
noname [10]

Answer:

t = 2n + 3

Step-by-step explanation:

Given

4n = 2(t - 3) ← divide both sides by 2

2n = t - 3 ( add 3 to both sides )

Let f(x) = log(x). Find values of a such that f(kaa) = kf(a).
meriva

Answer:

a = k^{\frac{1}{k-2}}

Step-by-step explanation:

Given:

f(x) = log(x)

and,

f(kaa) = kf(a)

now applying the given function, we get

⇒ log(kaa) = k × log(a)

or

⇒ log(ka²) = k × log(a)

Now, we know the property of the log function that

log(AB) = log(A) + log(B)

and,

log(Aᵇ) = b × log(A)

Thus,

⇒ log(k) + log(a²) = k × log(a)         (using log(AB) = log(A) + log(B) )

or

⇒ log(k) + 2log(a) = k × log(a)            (using log(Aᵇ) = b × log(A) )

or

⇒ k × log(a) - 2log(a) = log(k)

or

⇒ log(a) × (k - 2) = log(k)

or

⇒ log(a) = (k - 2)⁻¹ × log(k)

or

⇒ log(a) = \log(k^{\frac{1}{k-2}})          (using log(Aᵇ) = b × log(A) )

taking anti-log both sides

⇒ a = k^{\frac{1}{k-2}}
