Answer:

  • initial amount: $15.35
  • growth: 2.79% per day

Step-by-step explanation:

The coefficient is the initial amount: $15.35.

The growth factor is the base of the exponential term: 1.0279. The growth rate is 1 less than this: 1.0279 -1 = 0.0279 = 2.79%. It is positive, so represents a growth of 2.79% per day.

Given f(x) = 2x and<br> g(x) = x2+3 , find f(g(x)).
Nimfa-mama [501]

I'm assuming for g(x) you mean g(x) = x^2+3 for g(x)=x^2+3.

Going with that...

    \begin{aligned}f(g(x)) &= f\left( x^2+3 \right)~~~~~\text{plug $x^2+3$ in for $x$ in $f(x)$}\\[0.5em]&= 2\cdot ( x^2+3 )~~~~~\text{so $2x$ became $2(x^2+3)$}\\[0.5em]&= 2x^2+6\endaligned}

Just treat the enter g(x) function as a single input for f(x).

How many solutions does 4x + 5 = 6(x + 3) - 20 - 2x have? Show your work. SOLUTION ​
liq [111]

Answer:

There are no solutions.

Step-by-step explanation:

4x+5=6x+18-20-2x (Distributive Property)

4x+2x-6x=18-20+5 (Combine Like Terms)

0=3 (Simplify)

That doesn't make any sense, so there are no solutions.

Find a formula for the nth term
Airida [17]

Answer:

a_{n} = - 1.3n - 2.4

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference, thus

a_{n} = - 3.7 - 1.3(n - 1) = - 3.7 - 1.3n + 1.3 = - 1.3n - 2.4
