f(x) = 3x² - 6x + 2

f(- 2) = 3·(-2)² - 6·(-2) + 2

= 3·4 + 12 + 2

= 12 + 12 + 2

= 26

Answer:

just put

$x = - 2$

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

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

$f( - 2) = 3 \times 4 + 6 \times 2 + 2 =12+12+2 \\ f(-2)= 26$

2. Exercise 18, 19 Page 188. Determine if the following statements are true. If a statement is true, give a proof from the defin

Roman55 [17]

Answer:

a. true b. true

Step-by-step explanation:

<em>(a) If r and s are rational numbers, then (r+s)/2 is rational. </em>

true

rational numbers can be expresed as fractions

let be r=a/b and s=c/d being a,b,c,d integer numbers

$\frac{r+s}{2} =\frac{\frac{a}{b}+\frac{c}{d} }{2} =\frac{\frac{da+bc}{bd} }{2} =\frac{da+bc}{2bd}$

d.a=e is an integer number because it's the product of two integers

b.c=f is an integer number because it's the product of two integers

e+f=g is an integer number because it's the sum of two integers

b.d=h is an integer number because it's the product of two integers

2.h=i is an integer number because it's the product of two integers

g/i=j is an integer number because it's the quotient of two integers

then

$\frac{r+s}{2} =\frac{\frac{a}{b}+\frac{c}{d} }{2} =\frac{\frac{da+bc}{bd} }{2} =\frac{da+bc}{2bd}=\frac{e+f}{2h} =\frac{g}{i} =j$

<em>(b) For all real numbers a and b, if a < b then a < (a+b)/2 < b</em>

true

$a < (a+b)/2 < b$

$2a < (a+b) < 2b$

lets analyze 2a < (a+b)

$2a < (a+b) \\2a-a < (a+b)-a\\a < b$

then 2a < (a+b) is true

lets analyze (a+b) < 2b

$(a+b) < 2b\\(a+b)-b < 2b-b\\a< b$

then (a+b) < 2b is true

A candidate for mayor wants to know how strong her support is among voters, so she posts an online survey on her campaign websit

maks197457 [2]

1) A. Biased because the population could be uneven. Too many of one ethnicity, too many of one gender, etc.

2) I believe this one is C. because there are not enough people. You need to survey the majority of parents instead of a selected few.

3) There are 80 green marbles per 500, therefore calculate the percentage. $\frac{80}{500}=0.16$ or $16$ percent. Multiply $16$ percent or $0.16$ times 25. It gives you $4$ .

4) This one is a probability thing too. For every 500 batteries, there are 3 that are defective, therefore, $\frac{3}{500}= 0.006$ .

$0.006*12000 = 72$

5) Yet another one. Add up all the nuts and you get $48$ . The chance of getting a cashew from these $48$ is: $\frac{9}{48}=0.1875$ .

Therefore: $0.1875*32=6$
