Mathematics
1 answer:
dmitriy555 [2]4 years ago
3 0

Answer:

y = 64

Step-by-step explanation:

Using the rule of logarithms

• log_{b} x = n ⇔ x = b^{n}

Given

log_{y} 4 = \frac{1}3}, then

4 = y^{\frac{1}{3} }

Cube both sides

4³ = (y^{\frac{1}{3} })³, hence

y = 64

julia-pushkina [17]

Answer:

p(m) = 0.1(m)

Step-by-step explanation:

Given that :

Percentage of cost saved per month = 10%

The percentage, p of cost saved after m months will be ;

Percentage of cost saved after m, months will be ; p(m) = Percentage of cost saved per month * number of months

p(m) = 10% * m

p(m) = 0.1(m)

Let f(x)=√3x and g(x)=x-6 What's the smallest number that is in the domain of fog?
yaroslaw [1]

9514 1404 393

Answer:

  6

Step-by-step explanation:

Maybe you have ...

  f(x) = √(3x)

  g(x) = x-6

Then ...

  f(g(x)) = √(3(x -6))

The square root function is only defined for non-negative arguments, so we require ...

  3(x -6) ≥ 0

  x -6 ≥ 0 . . . . . divide by 3

  x ≥ 6 . . . . . . . . add 6

The smallest number in the domain of f(g(x)) is x = 6.

Factor the quadratic equation 0=15x squared + 39 x-18
leva [86]

Answer:

The factors of given quadratic equation

<em>   </em>x = \frac{9}{15} and x = -2<em />

Step-by-step explanation:

<u><em>Explanation:-</em></u>

<em>Given quadratic equation 15x² +39 x -18 =0</em>

<em> The factors of 270 = 30 × 9</em>

<em>The quadratic equation 15x² +39 x -18 =0</em>

<em>                                    ⇒ 15 x² +30 x-9x -18=0</em>

<em>                                 ⇒ 15x(x+2) -9( x+2) =0</em>

<em>                                ⇒( 15x -9)(x+2) = 0</em>

<em>                       15x - 9=0    and  x+2 =0</em>

<em>                       15 x =9   and  x = -2</em>

<em>                       </em>x = \frac{9}{15} and x = -2<em />

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