The domain of the function is composed by all the integer numbers that are greater than or equal to zero.

The domain of a function is the set containing all the possible input values that the function can accept.

For this problem, the input is the number of tickets purchased, which must be a countable amount (you cannot purchase a negative number of tickets nor a decimal number of tickets), hence the domain of the function is composed by all the integer numbers that are greater than or equal to zero.

Answer:

Step-by-step explanation:

The equation 12sec²x - 16 = 0 is not a polynomial equation and cannot be factored into the product of two or more polynomials.

To solve for x, we need to isolate sec²x by adding 16 to both sides and then dividing by 12:

12sec²x - 16 + 16 = 0 + 16

12sec²x = 16

sec²x = 16 / 12

sec²x = 4/3

Now that we have isolated sec²x, we can find x by finding the inverse secant of 4/3.

Note that the inverse secant is a multi-valued function, so there may be multiple solutions for x, which can be obtained using a calculator or tables of trigonometric functions.

Answer:

A) 11.26

Step-by-step explanation:

To find the state disability insurance (SDI) amount deducted from Caroline's paycheck, we need to calculate 1% of her gross earnings.

1% of $1,126 is (1/100) x $1,126 = $11.26

So, the SDI amount deducted from Caroline's paycheck would be $11.26.

False. The minimum of two independent exponential random variables is not necessarily exponential.

For two independent exponential random variables X and Y, with rate parameters λ1 and λ2 respectively, the minimum of X and Y is a random variable Z with the cumulative distribution function (CDF) given by

[tex]F_Z(z) = 1 - e^(-(λ1+λ2)z)[/tex].

The survival function of Z is given by

[tex]S_Z(z) = e^(-(λ1+λ2)z)[/tex].

Therefore, the probability density function of Z is

[tex]f_Z(z) = (λ1 + λ2)e^(-(λ1+λ2)z)[/tex].

This is not an exponential distribution because the form of the probability density function is not of the form [tex]f(z) = λe^(-λz)[/tex].

The graph of G(x) is the graph of F(x) compressed vertically.

The equation of the graph of F(x) is given by x^2 and that of G(x) is given by 4/5 x^2.

The coefficient of x^2 in the equation of G(x) is 4/5, which is smaller than the coefficient of x^2 in the equation of F(x), which is 1.

This means that for a given value of x, the value of G(x) will always be less than the value of F(x). In other words, the graph of G(x) will be closer to the x-axis compared to the graph of F(x), which is equivalent to compressing the graph of F(x) vertically.

The area of the region bounded by the lines y = 3x - 6 and y = -2x + 8 between the x-axis is 12/5 units

We can find the intersection point between these two lines;

y = 3x - 6

y = -2x + 8

Set these two equations equal to each other.

3x - 6 = -2x + 8

5x - 6 = 8

Add 6 to both sides of the equation.

5x = 14

Divide both sides of the equation by 5.

x = 14/5  

Find the y-value where these points intersect by plugging this x-value back into either equation.

y = 3(14/5) - 6

The graph of the first function is y = √(x - 5).

The graph of the second function is y =  |x - 1| + 4.

Suppose we have a function f(x).

f(x) ± d = Vertical upshift/downshift by d units (x, y ±d).

f(x ± c) = Horizontal left/right shift by c units (x - + c, y).

(a)f(x) = Vertical stretch for a > 0, vertical shrink a < 0. (x, ay).

f(bx) = Horizonatal compression b > 0, horizontal stretch for b < 0. (bx , y).

f(-x) = Reflection over y-axis, (-x, y).

-f(x) = Reflection over x-axis, (x, -y).

The graph of the first function is f(x) = y = √x.

Now, f(x - 5) would be the same function shifter 5 units to the right,

f(x) = √(x - 5).

The graph of the second function is  a modulus function shifted up 2 units and to right by 1 unit g(x) = |x - 1| + 2 and again g(x) + 2 =  |x - 1| + 4.

Arnav applies the Distributive Property to the expression 4 + 8(y + 3) + x.

Here we have to determine the equivalent expression after applying the Distributive Property to the expression 4 + 8(y + 3) + x.

Distributive property states that, for real numbers a, b, and c:

a (b + c) = ab + ac

An expression of the form A(B + C) can be solved as A × (B + C) = AB + AC.

From the given expression the part which we have to apply distributive property is 8(y + 3)

The initial amount, a, in the exponential function g(x) = 14 × 2x is 14, and the growth factor, b, is 2.

This can be determined by looking at the equation and noting that the coefficient of x is 2, which indicates that the base of the exponential is 2. We can also calculate the initial amount and growth factor mathematically.

To calculate the initial amount, a, we can take the equation g(x) = 14 × 2x and set x = 0, yielding g(0) = 14 × 20, which simplifies to 14. To calculate the growth factor, b, we can take the natural log of both sides of the equation to yield ln(g(x)) = ln(14 × 2x).

Simplifying this gives

ln(g(x)) = ln(14) + ln(2x).

We can then divide both sides by x to yield

ln(g(x))/x = ln(14) + ln(2)/x.

We can then take the limit as x approaches 0, which yields

ln(g(0))/0 = ln(14) + ln(2)/0.

This simplifies to

ln(g(0)) = ln(14) + ln(2), which can be rearranged to

ln(2) = ln(g(0)) - ln(14).

Taking the exponential of both sides gives us

2 = e^(ln(g(0)) - ln(14)), which simplifies to

2 = g(0)/14, or b = g(0)/14 = 2.

This shows that the initial amount, a, is 14, and the growth factor, b, is 2.

Step-by-step explanation:

If 6 times the 6th term of an A.P is equal to 9 times the 9th term, then 15th term of the A.P. is -2d with d as the common difference.

Let's call the common difference of the arithmetic progression (A.P.) "d". The nth term of an A.P. is given by the formula T = a + (n - 1)d, where a is the first term and n is the term number.

Using this formula, we can write two expressions for the 6th and 9th terms:

T₆ = a + (6 - 1)d = a + 5d

T₉ = a + (9 - 1)d = a + 8d

According to the problem, 6 times the 6th term of the A.P. is equal to 9 times the 9th term, so we can write the following equation:

6T₆ = 9T₉

Substituting the expressions for T₆ and T₉, we get:

6(a + 5d) = 9(a + 8d)

Expanding and solving for a, we get:

6a + 30d = 9a + 72d

Subtracting 6a from both sides:

24d = 3a + 72d

Subtracting 72d from both sides:

-48d = 3a

Dividing both sides by 3:

-16d = a

So, the first term of the A.P. is -16d.

To find the 15th term, we can use the formula for the nth term:

T₁₅ = a + (15 - 1)d = -16d + 14d = -2d

So, the 15th term of the A.P. is -2d.
