The radius of the cone to the nearest inch is equal to 8.0 inches.

In Mathematics and Geometry, the surface area (SA) of a cone can be calculated by using this mathematical expression:

Surface area (SA) of a cone = πr(l + r)

Where:

By substituting the given parameters into the formula for the surface area (SA) of a cone, we have the following;

364 = 3.14 × r(6.5 + r)

115.92 = 6.5r + r²

r² + 6.5r + 115.92 = 0

By solving the quadratic function, we have:

Radius, r = (-20.41 + √4988.4081)/6.28

Radius, r = 7.9966 ≈ 8.0 inches.

The domain to plot the growth function is 0 ≤ x < 7

Given that

f(d) = 11(1.01)ᵇ

When the radius is approximately 1179 mm

We have

11(1.01)ᵇ = 11.79

Divide

(1.01)ᵇ = 1.072

Take the logarithm

d = log(1.072)/log(1.01)

Evaluate

d = 6.99

So, the reasonable domain is 0 ≤ x < 7

Here, we have

f(d) = 11(1.01)ᵇ

The y-intercept is 11

This means tha the initial radius of the algae is 11 mm

For the average rate, we have

f(7) = 11(1.01)⁷ = 11.79

f(2) = 11(1.01)² = 11.22

So, we have

Rate  = (11.22 - 11.79)/(2 - 7)

Evaluate

Rate  = 0.114

So, the average rate of change from day 2 to day 7 is 0.114 mm per day

The solution of the equations is (6, 1).

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Using the substitution method.

We can start by setting the two expressions for Y equal to each other since they both represent the same value of Y:

-Y + 7 = (3/2)X - 3

Next, we can isolate Y on one side of the equation by subtracting 7 from both sides:

-Y = (3/2)X - 10

Then, we can multiply both sides of the equation by -1 to isolate Y and make it positive:

Y = -(3/2)X + 10

Now we have expressions for Y in terms of X for both equations. We can set them equal to each other to find the value of X that satisfies both equations:

-X + 7 = -(3/2)X + 10

To solve for X, we can start by adding (3/2)X to both sides:

(1/2)X + 7 = 10

Next, we can subtract 7 from both sides:

(1/2)X = 3

Finally, we can multiply both sides by 2 to solve for X:

X = 6

Now that we have found the value of X, we can substitute it back into one of the original equations to find the corresponding value of Y.

Let's use the first equation:

Y = -X + 7

Y = -6 + 7

Y = 1

Therefore,

The solution of the equations is (6, 1).

One possible transformation is a reflection in the x-axis followed by a dilation centered at the origin with a scale factor of 3.

A dilation can be defined as a transformation that multiplies the distance between every point in an object and a fixed point, called the center of dilation, by a constant factor called the scale factor.

Before the dilation, the figure was reflected from the first quadrant to the second quadrant, which is a lateral reflection, hence the figure was reflected over the x-axis.

The height of the blue triangle is of 1 unit, while the height of the larger triangle is of 3 units, hence the scale factor is given as follows:

The inequality is a < 10

Given that a number a is no more than 10, we need to find the inequality, showing the inequality,

Inequalities are the mathematical expressions in which both sides are not equal.

In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

For example = Olivia is selected in the 12U Softball. How old is Olivia? You don't know the age of Olivia, because it doesn't say "equals". But you do know her age should be less than or equal to 12, so it can be written as Olivia's Age ≤ 12.

Approximately 32.14% of the renters do not keep a pet.

We know that there are 28 units in the apartment complex. Out of these, 19 renters keep a pet. To calculate the number of renters who do not keep a pet, we subtract the number of renters with pets (19) from the total number of renters (28):

Number of renters without pets = Total number of renters - Number of renters with pets

Number of renters without pets = 28 - 19

Number of renters without pets = 9

Now that we have the number of renters without pets (9), we can calculate the percentage of renters who do not keep a pet. To do this, we divide the number of renters without pets by the total number of renters and multiply by 100:

Percentage of renters without pets = (Number of renters without pets / Total number of renters) × 100

Percentage of renters without pets = (9 / 28) × 100

Percentage of renters without pets ≈ 32.14%

Therefore, approximately 32.14% of the renters in the apartment complex do not keep a pet.

It will cost approximately $1,715.20 to carpet a room with 360 square feet of floor area, assuming the carpet costs $42.88 per square yard.

To calculate the cost of carpeting a room with a floor area of 360 square feet, we need to convert the area into square yards and then multiply it by the cost per square yard.

There are 9 square feet in a square yard (1 square yard = 3 feet x 3 feet = 9 square feet). Therefore, the room's floor area in square yards is:

360 square feet / 9 = 40 square yards

Next, we multiply the area (40 square yards) by the cost per square yard ($42.88) to find the total cost of carpeting the room:

Total cost = 40 square yards * $42.88 per square yard

Calculating this gives us the final result:

Given that,

The measure of rectangular  picture = 20 cm x 30 cm

And the resulting enclosed area = 1064 cm²

Let the length of each side = x

Therefore,

The new rectangular frame will have dimensions = 20 cm + x, 30 cm + x

The new rectangular frame's surface area is:

= (20 + x) x (30 + x).

Since area is given,

So that we can create an equation:  1064 = (20 cm + x) x (30 cm + x)

Increasing the brackets results in: 600 + 50x + x² = 1064

Organizing and making it simpler: x² + 50x - 464 = 0.

By using quadratic formula,

x = (-50 ± 174.96) / 2

Neglecting the undesirable outcome,

x = 62.98 / 2 x = 31.49

Consequently, each side length has increased by around 31.49 cm.

Use this value to determine the new rectangular frame's dimensions:

Length is equal to 20 + 31.49 = 51.49 cm.

Width is equal to 30 + 31.49 = 61.49 cm.

when k = 4, the function x + k/x will have a relative maximum at x = -2.

To find the value of k that will make x+k/x have a relative maximum at x=-2, we can use the first derivative test.

First, we find the derivative of x+k/x with respect to x:

f'(x) = 1 - k/x^2

Next, we set x = -2 and solve for k to make f'(-2) = 0:

f'(-2) = 1 - k/(-2)^2 = 1 - k/4

1 - k/4 = 0

k = 4

The statement to be proved is that if (an)[infinity]n=1 is a bounded sequence and (bn)[infinity]n=1 converges to 0, then (anbn)[infinity]n=1 converges to 0 as well.

To prove this statement, we can use the squeeze theorem. Let M be a bound for the sequence (an)[infinity]n=1, i.e., |an| <= M for all n. Since (bn)[infinity]n=1 converges to 0, for any ε > 0, there exists an integer N such that |bn| < ε/M for all n ≥ N.

Now, for any n ≥ N, we have

|anbn| = |an||bn| ≤ M|bn| < ε,

where we used the fact that |an| ≤ M. This shows that (anbn)[infinity]n=1 converges to 0 as well, since the absolute value of each term is bounded by ε for n ≥ N.

In other words, we have shown that for any ε > 0, there exists an integer N such that |anbn - 0| < ε for all n ≥ N. This is the definition of convergence to 0, and so we have proven that (anbn)[infinity]n=1 converges to 0.

The method used to determine the probability that a football team will win the next game is subjective.

The subjective method involves relying on personal judgment, experience, or expert opinion to estimate the probability of an event. In this case, the sports analyst has assessed various factors such as team performance, player injuries, historical data, and other relevant information to form their subjective opinion that the team's probability of winning is 0.37.

This method is based on the analyst's subjective assessment and may vary from one analyst to another. It does not involve any formal calculations or statistical techniques. The probability estimate is derived from the individual's knowledge, expertise, and perception of the situation.

It's important to note that subjective probabilities can be influenced by biases or personal opinions, and they may not always accurately reflect the true probability of an event.

To find the point of intersection between the two lines represented by the given equations, we can solve the system of equations simultaneously.

The given equations are:

1) X + Y = 2

2) Y = (1/2)X + 5

We can solve this system by substituting the value of Y from the second equation into the first equation. Let's proceed with the substitution method:

Substitute Y = (1/2)X + 5 into the first equation:

X + (1/2)X + 5 = 2

Combine like terms:

(3/2)X + 5 = 2

Subtract 5 from both sides:

(3/2)X = -3

Multiply both sides by 2/3 to isolate X:

X = -2

Now, substitute the value of X back into the second equation to find Y:

Y = (1/2)(-2) + 5

Y = -1 + 5

Y = 4

Therefore, the lines represented by the given equations intersect at the point (-2, 4).

Mathis's rate of return on his investment of $1,000 in a mutual fund that sold for $1,250, including taxes, inflation, and administrative costs of $8 was 24.2%.

The rate of return represents the percentage of the net gain an investment generates.

The rate of return is determined using the quotient of the division operation between the return and the initial investment.

The return or net return is the difference between the final value and the initial value after taking into account taxes, inflation, and other administrative costs.

The initial investment = $1,000

The final sales value = $1,250

Taxes, inflation, and other costs = $8

Net sales proceeds = $1,242 ($1,250 - $8)
