The definition of a reflection of rectangle ABCD is option D:

"Every point X on ABCD is mapped to a new point X' such that one coordinate of X' is the same as in X, and the other coordinate of X' is the opposite of the other coordinate in X".

When a reflection occurs, each point on the original shape is mapped to a new location on the reflected shape.

Option A states that every point X on ABCD is mapped to a new point X' such that each length from X to X' is the same. This definition does not capture the essence of a reflection because it doesn't consider the relationship between the original shape and its reflection.

Option B states that every point X on ABCD is mapped to a new point X' such that the distance from X to the line of reflection is the same as the distance from X' to the line of reflection.

Option C states that every point X on ABCD is mapped to a new point X' such that the coordinates of X' are opposites of the coordinates of X.

Option D correctly captures the nature of a reflection. This states that each point X on ABCD is mapped to a new point X' where one coordinate of X' is the same as in X, and the other coordinate of X' is the opposite of the other coordinate in X.

Therefore, option D is the valid definition of a reflection of rectangle ABCD.

Given:

The graph of an exponential function.

To find:

The exponential growth factor as x increases by 1 unit.

Solution:

From the given graph, it is clear that the exponential function passes through the points (1,1) and (3,9). So, the equation of the exponential must must be satisfy by these points.

The general exponential function is:

\(y=ab^x\)                 ...(i)

Where, a is the initial value and b is the growth factor.

Putting \(x=1,y=1\) in (i), we get

\(1=ab^1\)                  ...(ii)

Putting \(x=3,y=9\) in (i), we get

\(9=ab^3\)                  ...(iii)

Divide (iii) by (ii).

\(\dfrac{9}{1}=\dfrac{ab^3}{ab}\)

\(9=b^2\)

\(3=b\)

b is the the growth factor and the value of b is 3.

Therefore, the exponential growth factor is 3 as x increases by 1 unit.

Answer:

exponential growth factor is 3

The threshold price F * for insurance is F * = c1c2. If F >F *, it would not be rational for Nick to purchase insurance. If F < F *, it would be rational for Nick to purchase insurance as it provides a net benefit.

To find the threshold price F *  for insurance where Nick is indifferent over buying insurance, we need to determine the point at which Nick's expected utility is the same whether he purchases insurance or not.

Let's consider the two scenarios:

1. No insurance purchased (F' = 0):
In this case, if Nick consumes c1 chocolate bars in period 1 and c2 chocolate bars in period 2, his utility function becomes U(c1;c2;0) = c1c2.

2. Insurance purchased (F' = F):
If Nick purchases insurance by paying F upfront, his utility function becomes U(c1;c2;F) = c1c2 - F.

Now, let's find the threshold price F * by comparing the expected utilities for both scenarios:

1. No insurance:
The expected utility without insurance is the utility multiplied by the probability of not having his chocolate stolen (1 - 0.25 = 0.75):
E(U(c1;c2;0)) = 0.75 * (c1c2)

2. Insurance:
The expected utility with insurance is the utility multiplied by the probability of not having his chocolate stolen, minus the cost of insurance (F), multiplied by the probability of having his chocolate stolen (0.25):
E(U(c1;c2;F)) = 0.75 * (c1c2) + 0.25 * (c1c2 - F)

To find the threshold price F *, we set the expected utilities equal to each other and solve for F:
0.75 * (c1c2) = 0.75 * (c1c2) + 0.25 * (c1c2 - F)

By simplifying the equation, we get:
0 = 0.25 * (c1c2 - F)

Solving for F gives us:
F = c1c2

Therefore, the threshold price F * for insurance is F * = c1c2.

Now let's consider the scenarios when F > F * and F < F *:

- F > F *:
If the price of insurance (F) is greater than the threshold price (F *), it means that the cost of insurance is higher than the expected loss from chocolate being stolen. In this case, it would not be rational for Nick to purchase insurance because he would be paying more than the potential loss.

- F < F *:
If the price of insurance (F) is less than the threshold price (F *), it means that the cost of insurance is lower than the expected loss from chocolate being stolen. In this case, it would be rational for Nick to purchase insurance as it provides a net benefit by reducing the potential loss.

In summary, the threshold price F * for insurance is F * = c1c2. If F > F *, it would not be rational for Nick to purchase insurance. If F < F *, it would be rational for Nick to purchase insurance as it provides a net benefit.

The state legislature is composed of 215 senators and 45 representatives.

Given that,

There are senators and representatives in a certain state legislature. There are 260 senators and representatives in all. The numerical difference is 170. There are more legislators than representatives.

To find : In this state's legislature, how many senators and representatives are there?

Given that,

x + y = 260

x-y = 170

By using algebra,

Subtracting equation 2 from 1,

x+y -x+y = 260 - 170

2y = 90

y = 45

To find x,

x + y = 260

x = 260 - y

x = 260-45

x = 215

The equation log(8x+2) = 3 can be rewritten in exponential form as 10^3 = 8x+2. Simplifying, we get:

1000 = 8x + 2

998 = 8x

x = 124.75

Therefore, the solution to the equation is x = 124.75, which is an approximation to 3-decimal places.

To verify the solution, we can substitute x = 124.75 back into the original equation and check if both sides are equal:

log(8(124.75) + 2) = log(1000)

log(1000) = 3

Since both sides are equal, we can conclude that x = 124.75 is indeed the solution to the equation.
