Hello!

To transform the normal, standard numbering to centric notation, simply remove the zeros prior to the point, and raise the remainder to the number of zeros in their negative form. 0.0078 = 7.8 * 10 -3.

What logarithmic function represents the data in the table?

alina1380 [7]

216 =6^3
1,296 = 6^4
7,776 = 6^5
x = 6^f(x)
log x = log 6^f(x) = f(x)log 6
f(x) = log x / log 6 = $log_6x$

X2-4x=-4 Solve using quadratic formula (find x)

Amiraneli [1.4K]

Answer:

x=2

Step-by-step explanation:

$x^2-4x=-4$

$x^2-4x+4=-4+4$ (Add 4 to both sides)

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

Now, we can solve it using quadratic formula

$x_{1,\:2}=\cfrac{-\left(-4\right)\pm \sqrt{\left(-4\right)^2-4* \:1* \:4}}{2* \:1}$

$x_{1,\:2}=\cfrac{-\left(-4\right)\pm \sqrt{0}}{2* \:1}$

$x=\cfrac{-\left(-4\right)}{2* \:1}$

$x=2$

PLEASE HELP!!!!! WILL GIVE BRAINLIEST!!!

If sin x = 0.5, then x = sin^-1( 0.5) = 30°. This is also one of the special valuse of sine that you should have memorized. It makes it easier if you can just remember these values rather than calculating them each time (especially in certain no calculator tests!).
