6.5 x 2 = 13, because 6 x 2 = 12, and .5 x 2 = 1, and 12 + 1 = 13.

Which graph shows the quadratic function y = 3x2 − 12x + 10? (5 points)

eduard

ANSWER

The graph in option D.

EXPLANATION

The given function is:

$y = 3 {x}^{2} - 12x + 10$

We complete the square to obtain:

$y = 3( {x}^{2} - 4x) + 10$

$y = 3( {x}^{2} - 4x + {( - 2)}^{2} ) + 10 - 3 {( - 2)}^{2}$

$y = 3{( x- 2)}^{2}+ 10 - 12$

$y = 3{( x- 2)}^{2} - 2$

The graph of this function opens upwards and has its vertex at (2,-2).

The y-intercept is 10.

From the options the graph that satisfies all these properties is D.

In a batch of 890 calculators, 12 were found to be defective. What is the probability that a calculator chosen at random will be

scoray [572]

Answer:

When entered into a calculator, 12/890 (the chance of a given calculator being defective) = 0.01348...

As a percent this is 100*0.01348% = 1.348%, and to the nearest tenth, 1.3%

Ex 2.6

Anna007 [38]

$y=3x^4 -4x^3 -12x^2 +1\\
y'=12x^3-12x^2-24x\\\\
12x^3-12x^2-24x=0\\
12x(x^2-x-2)=0\\
12x(x^2+x-2x-2)=0\\
12x(x(x+1)-2(x+1))=0\\
12x(x-2)(x+1)=0\\
x=0 \vee x=2 \vee x=-1\\\\
\forall{x\in(-\infty,-1)\cup(0,2)}\ y'$
$y(-1)=3\cdot(-1)^4-4\cdot(-1)^3-12\cdot(-1)^2+1=3+4-12+1=-4=\\
=y_{min}$
