A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:

f(d) = 11(1.01)d

Part A: When the biologist concluded her study, the radius of the algae was approximately 11.79 mm. What is a reasonable domain to plot the growth function? (4 points)

Part B: What does the y-intercept of the graph of the function f(d) represent? (2 points)

Which statement is true about the graphed function?

F(x) < 0 over the interval (–∞, –4)
F(x) < 0 over the interval (–∞, –3)
F(x) > 0 over the interval (–∞, –3)
F(x) > 0 over the interval (–∞, –4)

Answers

The true statement, regarding the signal of the graphed function, is given by:

F(x) > 0 over the interval (–∞, –4).

When a function is positive and when it is negative?

Looking at it's graph, we have that:

The function is positive when it is above the x-axis.The function is negative when it is below the x-axis.

Researching this problem on the internet and looking at the graph of the function, the function is negative for all values to the right of x = -4,  and positive to the left, hence the correct statement is given by:

F(x) > 0 over the interval (–∞, –4).

sketch the graph of f and f on the same set of axes
​

Answers

The graph of the function \(f(x) = (9/4)x^2\) is a symmetric upward-opening parabola.

The graph represents a parabola that opens upward. As x increases, the corresponding y-values increase, forming a curved shape. The vertex of the parabola is at the origin (0,0). The graph is symmetric with respect to the y-axis, meaning that the left and right sides of the parabola are mirror images of each other.The slope of the graph gradually increases as x moves away from the origin. The steepness of the curve becomes more pronounced, indicating a faster rate of increase in y-values for larger x-values.The graph does not intersect the x-axis, indicating that there are no real roots or solutions for the equation f(x) = 0. The y-intercept of the graph is at (0, 0), and the y-values increase indefinitely as x approaches positive or negative infinity.

Overall, the graph represents a quadratic function with a positive leading coefficient, resulting in an upward-opening parabolic curve. The graph has been attached.

Answer:

x² - x - 2

Step-by-step explanation:

Since the curve cuts the x-axis at x = -1 and 2. The factors will be x+1 and x-2

Taking the product of the factors

f(x) = (x+1)(x-2)

f(x) = x² - 2x + x - 2

f(x) = x² - x - 2

Hence the required function is x² - x - 2

You are given the great circle of a sphere is a length of 25 miles. What is the volume of the sphere

Answers

The volume of the sphere is approximately 3431.82 cubic miles.

To find the volume of a sphere, we need the radius of the sphere. The length of a great circle is the circumference of the sphere, which is related to the radius by the formula C = 2πr, where C is the circumference and r is the radius.

In this case, we are given that the length of the great circle is 60 miles. We can use this information to find the radius of the sphere.

C = 2πr

60 = 2πr

Divide both sides of the equation by 2π:

r = 60 / (2π)

r = 30 / π

Now that we have the radius, we can use the formula for the volume of a sphere:

V = (4/3)πr³

V = (4/3)π(30/π)³

V = (4/3)π(27000/π³)

V = (4/3)π(27000/π³)

V = (4/3)π(27000/π³)

V = (4/3)(27000/π²)

V = (4/3)(27000/9.87) (approximating π to 3.14)

V ≈ 3431.82 cubic miles

Therefore, the volume of the sphere is approximately 3431.82 cubic miles.

Range,median,mean,mode for 79,83,94,86,90,84,86

Answers

The range is 5. The mean is 86. The mode is 86. The median is 86.

What is the range, median, mean and mode?

The numbers arranged in ascending order is 79, 83, 84, 86, 86, 90, 94

Range is the difference between the highest and lowest values of a set of observations

Range = highest value - lowest value

94 - 79 = 5

Mean is the average of a set of numbers.

Mean  = sum of numbers / total number in the dataset

(79 + 83 + 84 + 86 + 86 + 90 + 94) / 7 = 602 / 7 = 86

Mode is the number that appears with the most frequency in the dataset. 86 appears twice in the dataset.

Median is the number at the center of the dataset.

Median = (n + 1) / 2

Where n is the numbers in the observation

(7 + 1) / 2 = 4th number = 86

Height = 9 cm

You roll a fair six-sided die twice. Find the probability of rolling a 5 the first time and a number greater than 2 the second time.

Answers

Answer:

The probability is 1/9

Step-by-step explanation:

The probability of rolling a 5 the first time is 1/6

The probability of rolling a number greater than 2

Numbers greater than 2 are; 3,4,5,6

So the probability of rolling a number out of this four is 4/6

Hence, the probability of rolling a five for the first time and the probability of rolling a number greater than 2 the second time will be;

1/6 * 4/6 = 4/36 = 1/9

which expression is equivalent to the expression shown 3^7 x 3^-4

Answers

Answer:

3^7x1/3^4

Step-by-step explanation:

which expression is equivalent to the expression shown 3^7 x 3^-4

We want to find an equivalent expression to the given one.

We will see that an equivalent expression to the given one is 3^3 or 27.

Let's see how to solve this problem.

First, two expressions are equivalent if the expressions represent the exact same thing.

So if we only rewrite the given expression, we will get an equivalent expression.

To rewrite it, we can use the exponent property:

\(a^n*a^m = a^{n + m}\)

Then the given expression:

\(3^7*3^{-4}\)

Can be rewritten as:

\(3^{7 + (-4)} = 3^3 = 27\)

Then the equivalent expression to the given one can be 3^3 or 27.

What is standard deviation?

Standard deviation is a measurement of how evenly distributed a set of numbers is. Since the variance is the squared average of the squared deviations from the mean, it represents the square root of the variance.For instance: To determine the standard deviation, sum all of the numbers inside this data set, divide by the total number of numbers, and the result is the standard deviation.

If the shortest was 11cm how long was the ribbon

Answers

99cm

Answer: Total Length of ribbon is 99 cm

Step-by-step explanation:

Here ribbon was cut into three parts in the ratio 1:3:5

let x be the common multiple of the above ratio

therefore, the lengths of the three parts of the ribbon is 1x,3x,5x

now, given is that the shortest part i.e 1x is equals to 11cm

i.e   1x=11

        x=\(\frac{11}{1}\)=11cm

     now lengths of the ribbon will be

      1x=11cm, 3x=3*11=33cm, 5x=5*11=55cm

 now total length of piece of ribbon = 1x+3x+5x=9x=9*11=99cm
