Let's solve your equation step-by-step.

<span><span><span>4s</span>−<span>4<span>s2</span></span></span>=1

</span>Step 1: Simplify both sides of the equation.

<span><span><span>−<span>4<span>s2</span></span></span>+<span>4s</span></span>=1

</span>Step 2: Subtract 1 from both sides.

<span><span><span><span>−<span>4<span>s2</span></span></span>+<span>4s</span></span>−1</span>=<span>1−1

</span></span><span><span><span><span>−<span>4<span>s2</span></span></span>+<span>4s</span></span>−1</span>=0

</span>Step 3: Factor left side of equation.

<span><span><span>(<span><span>−<span>2s</span></span>+1</span>)</span><span>(<span><span>2s</span>−1</span>)</span></span>=0

</span>Step 4: Set factors equal to 0.

<span><span><span><span>−<span>2s</span></span>+1</span>=<span><span><span>0<span> or </span></span><span>2s</span></span>−1</span></span>=<span>0

s = 1/2</span></span>

How do I figure this out ?

grandymaker [24]

Answer:

0.0082

Step-by-step explanation:

The n th term of a geometric sequence is

$a_{n}$ = a₁ $(r)^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = - 2 and r = - $\frac{1}{3}$ , thus

$a_{6}$ = - 2 $(-\frac{1}{3}) ^{5}$ = - 2 × - $\frac{1}{243}$ = $\frac{2}{243}$ ≈ 0.0082 ( nearest ten- thousandth )

Which expression represents the composition [g o f o h](x) for the functions below?

Brut [27]

Answer:

A

5(15x-4)^3

Explanation:

I assume you mean g(f(h(x))) so in that case here is how you do it:

So the first one is g(x) which is:

5x^3

Now g(f(x)) you just plug in f(x) for the x in the g equation. It would look like this:

5(5x-4)^3

Now the h(x) you would do the same, plug it in for all the values of x in g(x). So it would look like this:

5(5(3x)-4)^3

Since you simplify, you get 5(15x-4)^3

This final equation is g(f(h(x))) which is what you were looking for, which is A
