Answer:

18

Step-by-step explanation:

To find the minimum value of the function we have to find the vertex.

f(x) = x^2 - 6x + 3

Vertex point is (h, k)

$h=\frac{-b}{2a} $

$h=\frac{-(-6)}{2(1)} $

$h=\frac{6}{2} $

h=3

In order to find k

f(h) = h^2 - 6h + 3

k=f(3) = 3^2 - 6(3) + 3

k= 9 - 18 + 3

k=-6

Vertex point is (3, -6)

The difference between the maximum value of g(x) and the minimum value of f(x) is

12-(-6)=12+6=18

To find the max/ min of a function use the formula x = - b/2a

in the function x^2 - 6x +3, a would be the number in front of the x^2, since there is no number, a = 1. b is the number in front of x , which is -6, so b = -6

Now you have x = -(-6) /2(1) = 6/2 = 3

Now you have a value for x, replace it in the formula and solve:

3^2 - 6(3) + 3 = 9 -18 +3 = -6

The minimum is -6

The max of the graph is the highest point which is 12

The difference is 12 - -6 = 12 +6 = 18

The answer is 18

4^x-2\cdot5^{2x}-10^x>0

$\implies 2^{2x}-2\cdot5^{2x}-(2^x)(5^x)>0$

let $2^x=a$ and $5^x=b$

So, $a^2-2b^2-ab>0$

divide by $b^2$, ($b^2>0$)

$\implies \left(\frac ab\right)^2-\left(\frac ab\right) -2>0$

this is a quadratic, in $\left(\frac ab\right)$, let it be $x$

So, $x^2-x-2>0$

Can you simplify it now?

Answer:

p = 15/40

Step-by-step explanation:

Since the total number of marbles is 40, that is our size of the sample. there are 16 red ones on that sample, so the probability of extracting a red marble from the box is given by the ratio of successes divided the total number of marbles:

p = 15/40
