ASAP WILL MARK BRAINLYEST answer these two please!

Trava [24]

$19.\\y=3x^2\\a=3,\ b=0,\ c=0\\\\\dfrac{-b}{2a}=\dfrac{-0}{2(3)=0\to x=0\\\\3x^2=0\ \ \ \ |:3\\\\x^2=0\to x=0$

$20.\\y=x^2-x-2\\a=1,\ b=-1,\ c=-2\\\\\dfrac{-b}{2a}=\dfrac{-(-1)}{2(1)}=\dfrac{1}{2}\to x=\dfrac{1}{2}\\\\x^2-x-2=0\\\\x^2-2x+x-2=0\\\\x(x-2)+1(x-2)=0\\\\(x-2)(x+1)=0\iff x-2=0\ \vee\ x+1=0\\\\x=2\ \vee\ x=-1$

Growth or decay help!!!!

Vsevolod [243]

If the antique's value increases over time, it must be growing (not decaying) in value.

We're told the value increases by 12.12%, which means that if the current value is $x$ , then the value after 1 year is $x+0.1212x=1.1212x$ . Each year, the value increases by the same factor, which means after 2 years, the value is $1.1212(1.1212x)=1.1212^2x$ ; after 3 years, the value is $1.1212^3x$ ; and so on.

Here $x$ is the starting value of the antique. So the answer is the second choice.

Given the function h(x)=-x^2+4x+12, determine the average rate of change of the function over the interval −2≤x≤4.

iris [78.8K]

Answer:

Step-by-step explanation:

The average rate of change of h(x) in the closed interval [ a, b ] is

$\frac{f(b) - f(a)}{b-a}$
