Axis of symmetry is the straight line that divides a parabola into two parts.
Usually it's found at vertex

Here the vertex is (2,-3)

Axis of parabola is x axis so

Axis of symmetry is x co-ordinate i.e x=2

The probability that Brian wins a raffle is given by the expression n n + 2 . Write down an expression, in the form of a combine

LUCKY_DIMON [66]

Answer:

$\frac{2}{n+2}$

Step-by-step explanation:

Given

Let the total probability be 1

Probability that Brian wins a raffle = n/n+2

Probability that Brian does not win a raffle = 1 - Probability that Brian wins a raffle

Probability that Brian does not win a raffle = 1 - (n/n+2)

Probability that Brian does not win a raffle = $\frac{n+2-n}{n+2}$

Probability that Brian does not win a raffle = $\frac{2}{n+2}$

Hence required fraction is $\frac{2}{n+2}$

Use natural logarithms to solve the equation 9e 4x = 54 forx. Give the exact solution and an approximate

GuDViN [60]

Answer:

.448

Step-by-step explanation:

$9e^{4x} = 54 \\e^{4x} = 54/9\\e^{4x} = 6\\ln{6} = 4x\\ln{6}/4 = x\\.448 =x\\(approx)$

The domain of u(x) is the set of all real values except 0 and the domain of v(x) is the set of all real values except 2. What ar

muminat

Answer:

Third option

x ≠2 and x cannot be any value for which v(x) = 0

Step-by-step explanation:

In this problem we are asked to find the domain of the function

$(UoV)(x)$

We know that $(UoV)(x) = U(V(x))$ .

We know that:

Domain of U(x) is all real numbers except x = 0

Domain of V(x) is all real numbers except x = 2.

Then the domain of the composite function U(V (x)) is:

all real numbers except x = 2. (since x = 2 does not belong to the domain of V(x) and all values of x for which V(x) = 0 (since x = 0 does not belong to the domain of U(x))

Finally the domain of $(UoV)(x)$ ) is:

$x \neq 2$ and $V(x) \neq 0$
