If f(x) = 5x(3exponent) - 2 and g(x) = 2x+1 , find (f+g) (x)

Rus_ich [418]

For this case we must find

$(f + g) (x).$

By definition we have to:

$(f + g) (x) = f (x) + g (x)$

We have the following functions:

$f (x) = 5x ^ 3-2\\g (x) = 2x + 1$

Now, applying the given definition, we have:

$(f + g) (x) = 5x ^ 3-2 + 2x + 1\\(f + g) (x) = 5x ^ 3 + 2x-1$

Answer:

$(f + g) (x) = 5x ^ 3 + 2x-1$

The number 2400 is first increased by 30%.The value obtained is next decreased by 20%.Find the final number

kvasek [131]

<em>2400 is increased by 30%.</em>

so,

2400 + (30/100 * 2400)

2400 + (30 * 24)

2400 + 720

3120

<em>this number is decreased by 20%.</em>

so,

3120 - (20/100 * 3120)

3120 - (2 * 312)

3120 - 624

2496

therefore, the final number will be 2496.
