Evaluate the function rule for the given value. y=15*3^x for x = -3

DENIUS [597]

Answer: $y=\frac{5}{9}$

Step-by-step explanation:

It is important to remember that an Exponential function has the following form:

$f(x) =a* b^x$

Where “b” is $b > 0$ and $b \neq 1$ , "a" is a coefficient, "x" is the Independent variable and f(x) is the Dependent variable.

In this case, you have the following Exponential Function given in the exercise:

$y=15*3^x$

If the value of Dependent variable is -3, then:

$x=-3$

So, you must substitute that value of "x" into the function:

$y=15*3^{(-3)}$

And now you must evaluate:

1. According the Negative exponent rule:

$a^{-n}=\frac{1}{a^n}$

Then:

$y=\frac{15}{3^{3}}$

2. Simplifying, you get:

$y=\frac{15}{27}\\\\y=\frac{5}{9}$

Please help asap<br><br> solve x^4+5x^2+4=0

const2013 [10]

Answer:

$x=\pm i\text{ or }x=\pm2i$

Step-by-step explanation:

So we have the equation:

$x^4+5x^2+4=0$

Let's let u be equal to x². So:

$u^2+5u+4=0$

Factor:

$(u+1)(u+4)=0$

Zero Product Property:

$u+1=0\text{ or } u+4=0$

Subtract:

$u=-1\text{ or }u=-4$

Replace:

$x^2=-1\text{ or }x^2=-4$

Take square root:

$x=\pm\sqrt{-1}\text{ or }x=\pm\sqrt{-4$

Simplify:

$x=\pm i\text{ or }x=\pm2i$
