D is the midpoint of segment BC.(given)
Let's add another given saying angle 1 is congruent to angle 2.
Let's prove that triangle ADB is congruent to triangle ADC
So BD=DC (definition of midpoint) and AD=AD (reflexive prop) and measure of angle 1= measure of angle 2. So using SAS post. we get that triangle ADB= triangle ADC.

PLS HELP f(x)=x^3−2x^2+12x−6 g(x)=4x^2−6x+4 What is (f−g)(x)?

vodomira [7]

Answer:

$(f - g)(x) = {x}^{3} - 6 {x}^{2} + 18x - 10$

Step-by-step explanation:

The given functions are:

$f(x) = {x}^{3} - 2 {x}^{2} + 12x - 6$

and

$g(x) = 4 {x}^{2} - 6x + 4$

We want to find

$(f - g)(x)$

Recall that:

$(f - g)(x) = f(x) - g(x)$

This implies that:

$(f - g)(x) = {x}^{3} - 2 {x}^{2} + 12x - 6 - (4 {x}^{2} - 6x + 4)$

$(f - g)(x) = {x}^{3} - 2 {x}^{2} + 12x - 6 - 4 {x}^{2} + 6x - 4$

We combine similar terms to get:

$(f - g)(x) = {x}^{3} - 6 {x}^{2} + 18x - 10$

By what percent is the change in price if: the price was $250 and now is $100

drek231 [11]

Answer: 60 percent decrease

===========================================

Change in price = new - old = 100 - 250 = -150

The negative change means the price has gone down

Divide this change in price over the original 250 and convert to percent form

(change in price)/(original price) = -150/250 = -0.60

which converts to -60%

The negative percent change in price indicates a price decrease

So the price goes down by 60% meaning that it lost 60% of its value

Note how 60% of 250 is 0.60*250 = 150 which was the change in price computed earlier.
