The decay factor r is 0.5, which means the exponential decay function that best represents the relationship between f(t) and t is:

\(f(t) = 100 \times (0.5^t)\)

To determine the exponential function that best represents the relationship between f(t) and t, we can analyze the given data points.

We notice that as time t increases, the amount of radioactive material f(t) decreases.

We can start by examining the ratio of f(t) at successive time intervals:

f(1)/f(0) = 50/100 = 0.5

f(2)/f(1) = 25/50 = 0.5

From this observation, we can conclude that the ratio of f(t) to f(t-1) remains constant at 0.5 for each time interval.

This indicates an exponential decay function.

The general form of an exponential decay function is given by: \(f(t) = a \times (r^t),\)

where a is the initial amount and r is the decay factor.

By substituting the given values from the table, we can solve for the decay factor r:

\(f(0) = a \times (r^0) = a = 100\)

\(f(1) = a \times (r^1) = 100 \times r = 50\)

\(f(2) = a \times (r^2) = 100 \times (r^2) = 25\)

Dividing the equation \(f(2) = 100 \times (r^2) = 25 by f(1) = 100 \times r = 50,\)

we get:

\((r^2) / r = 25/50\)

r = 0.5

Therefore, the decay factor r is 0.5, which means the exponential decay function that best represents the relationship between f(t) and t is:

\(f(t) = 100 \times (0.5^t)\)  

This equation indicates that the amount of radioactive material decreases by half every time unit.

Based on the data, the estimated number of lemon candies in the bag of 100 assorted candies is about 19.

In mathematics, proportion refers to the relationship between two quantities that are equivalent or have a constant ratio. It is usually expressed as a fraction or a ratio. For example, if a recipe calls for 2 cups of flour and 1 cup of water, the proportion of flour to water is 2:1 or 2/1. Proportions are used in a variety of mathematical and real-world situations, such as solving problems involving ratios, rates, and percentages.

In the given question,

We can use a simple proportion to estimate the number of lemon candies in the bag. We know that Ridgette handed out a total of 6 lemon candies out of a total of candies. Therefore, the proportion of lemon candies in the bag is:

6/total candies = number of lemon candies/100

We can cross-multiply to solve for the number of lemon candies:

number of lemon candies = 6 x 100 / total candies

We can also use the information about the other flavors to estimate the total number of candies in the bag. The total number of candies is:

total candies = lemon + orange + grape + cherry

Using the information from the table, we can estimate the total number of candies:

total candies = 6 + 5 + 8 + 13 = 32

Therefore, the estimated number of lemon candies in the bag is:

number of lemon candies = 6 x 100 / 32 = 18.75

We can round this to the nearest whole number to estimate that there were about 19 lemon candies in the bag of 100 assorted candies.

Answer:

-72x - 53y + 287 = 0.

Step-by-step explanation:

To find the equation of the image of the circle, we need to reflect each point on the circle in the given line mirror.

The line mirror equation is given as 4x + 7y + 13 = 0.

The reflection of a point (x, y) in the line mirror can be found using the formula:

x' = (x - 2Ay - 2B(Ax + By + C)) / (A^2 + B^2)

y' = (y - 2Bx + 2A(Ax + By + C)) / (A^2 + B^2)

where A, B, and C are the coefficients of the line mirror equation.

For the given line mirror equation 4x + 7y + 13 = 0, we have A = 4, B = 7, and C = 13.

Now, let's find the equations of the image of the circle.

The original circle equation is x² + y² + 16x - 24y + 183 = 0.

Using the reflection formulas, we substitute the values of x and y in the circle equation to find x' and y':

x' = (x - 2Ay - 2B(Ax + By + C)) / (A^2 + B^2)

= (x - 2(4)y - 2(7)(4x + 7y + 13)) / (4^2 + 7^2)

= (x - 8y - 8(4x + 7y + 13)) / 65

= (x - 8y - 32x - 56y - 104) / 65

= (-31x - 64y - 104) / 65

y' = (y - 2Bx + 2A(Ax + By + C)) / (A^2 + B^2)

= (y - 2(7)x + 2(4)(Ax + By + C)) / (4^2 + 7^2)

= (y - 14x + 8(Ax + By + C)) / 65

= (y - 14x + 8(4x + 7y + 13)) / 65

= (57x + 35y + 104) / 65

Therefore, the equation of the image of the circle is:

(-31x - 64y - 104) / 65 + (-57x + 35y + 104) / 65 + 16x - 24y + 183 = 0

Simplifying the equation, we get:

-31x - 64y - 57x + 35y + 16x - 24y + 183 + 104 = 0

-72x - 53y + 287 = 0

So, the equation of the image of the circle is -72x - 53y + 287 = 0.

Answer:

The question isn't clear. Can you provide more information or context? What is A? Is it a set or a number? Without this information, I can't provide a meaningful answer.

Answer:

D. f(x) = √(1 + x).

Step-by-step explanation:

I'm assuming the () stands for f(x) and the root of 1 - and the root of 1+ has "x" at the end of them.

To determine which function is increasing, we need to check whether the function values increase as the input variable increases.

A. f(x) = √x^2 is equal to |x|, which is increasing for x ≥ 0 and decreasing for x < 0. So, f(x) is increasing for x ≥ 0.

B. f(x) = √1 is a constant function, which is neither increasing nor decreasing.

C. f(x) = √(1 - x) is decreasing for x in the domain [0,1], since as x increases in this domain, the square root of 1-x gets smaller. Therefore, f(x) is not an increasing function.

D. f(x) = √(1 + x) is an increasing function, since as x increases, the square root of 1+x also increases.

Therefore, the function that is increasing is D. f(x) = √(1 + x).

Step-by-step explanation:

The vertex is at (-3, -1)  and the leading coefficient is negative ( because  the curve is inverted)

y = -a(x + 3)^2 - 1

One point on the curve is (-2, -3) so

-3 = -a(-2+3)^2 - 1

-3 = -a - 1

-a = -2

So we have

y = -2(x + 3)^2 -  1

y = -2(x^2 + 6x + 9) - 1

y = -2x^2 - 12x - 19.

The graph of the function y = 2|x| is a vertical stretch by a factor of 2 of the parent function y = |x|.

The functions for this problem are defined as follows:

When a function is multiplied by 2, we have that it is vertically stretched by a factor of 2.

Hence the graph of the function y = 2|x| is a vertical stretch by a factor of 2 of the parent function y = |x|.

Option (b) is the correct answer: Perpendicular segments.

Perpendicular rays, perpendicular segments, perpendicular lines, and parallel lines are important concepts in geometry that describe the relationship between lines and line segments.

1. Perpendicular Rays: Perpendicular rays are two rays that intersect at point and form a right angle (90 degrees) at the point of intersection. The rays extend indefinitely in opposite directions from the point of intersection.

2. Perpendicular Segments: Perpendicular segments are line segments that intersect at a right angle. They share a common endpoint but do not extend indefinitely like rays. The right angle is formed at the point of intersection.

3. Perpendicular Lines: Perpendicular lines are lines that intersect at a right angle. They continue indefinitely in opposite directions and form four right angles at the point of intersection. Perpendicular lines are often denoted by a symbol ⊥.

4. Parallel Lines: Parallel lines are lines that never intersect. They remain equidistant from each other at all points. Parallel lines have the same slope and do not converge or diverge. In Euclidean geometry, parallel lines are denoted by a double vertical line symbol (||).

Understanding these concepts is fundamental in geometry as they help define angles, shapes, and spatial relationships. The properties of perpendicular and parallel lines play a crucial role in various geometric theorems and applications.

After answering the presented question, we can conclude that Therefore, the slope of the line is -2/3.

In mathematics, slope is the steepness of a line or curve. It is a measure of how much a function's y-value fluctuates when the x-value changes. A line's slope is commonly symbolised by the letter m and may be computed as follows: m = (y2 - y1) / (x2 - x1) (x1, y1) and (x2, y2) are any two points on the line. The slope of a line might be positive, negative, zero, or unknown. A positive slope means the line ascends from left to right, whereas a negative slope means the line drops from left to right.

To find the slope of the line, we need to use the fact that the line is parallel to the line y = -2/3x + 1.

\(y - y1 = m(x - x1)\\y - (-1) = (-2/3)(x - 4)\\y + 1 = (-2/3)x + 8/3\\y = (-2/3)x + 5/3\)

So, the equation of the line that is parallel to y = -2/3x + 1 and passes through the point (4, -1) is y = (-2/3)x + 5/3.

Therefore, the slope of the line is -2/3.
