PLZZZ HELPPPPP

Answer:

78.5 cm

Step-by-step explanation:

The area of a circle is represented by A = πr². Since we are replacing the value of pi(π) with 3.14, and the diameter is 10, meaning the radius(r) is 5, we can plug both values into the equation, to get A = 3.14(5^2). This simplifies to 78.5.

Answer:

\(solution \\ diameter = 10 \: cm \\ radius = \frac{10}{2} = 5 \: cm \\ area \: of \: circle = \pi \: {r}^{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3.14 \times {5}^{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3.14 \times 5 \times 5 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3.14 \times 25 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 78.5 {cm}^{2} \)

Each component will have a triangle pyramid on top of a rectangle prism. equation The base of the rectangle prism will match the L shape's base, and its height will match the L shape's height.

A math equation is a procedure that connects two claims and uses the equals symbol (=) to denote equivalence. An equation in algebra is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, in the calculation 3x + 5 = 14, the equal sign places a space between the values 3x + 5 and 14. The relationship between the two sentences that are written on each side of a letter may be understood using a mathematical formula. The logo and the specifically software are frequently the same. as in, 2x - 4 Equals 2, for instance.

We must locate a line of symmetry that will separate the irregular form into two congruent sections in order to split it into two rectangular prisms. According to the description, when the two rectangular prisms are pressed together, the three-dimensional form resembles the letter L. We can therefore infer that the plane of symmetry follows the L shape's longitudinal line.

This plane of symmetry can be used to separate the L form into two congruent sections. Each component will have a triangle pyramid on top of a rectangle prism. The base of the rectangle prism will match the L shape's base, and its height will match the L shape's height.

The biggest decrease in waiting time between two consecutive eruptions is 18 minutes.

Here, we have,

To assign the biggest decrease to the biggest decrease in waiting time between two consecutive eruptions, we need to compare the decreases in waiting time for each pair of consecutive eruptions and identify the pair with the largest decrease.

Let's consider a sequence of eruption waiting times as an example:

Eruption 1: 60 minutes

Eruption 2: 70 minutes

Eruption 3: 74 minutes

Eruption 4: 62 minutes

Eruption 5: 80 minutes

To find the biggest decrease in waiting time, we compare the differences between consecutive eruptions:

Decrease between Eruption 1 and Eruption 2: 70 - 60 = 10 minutes

Decrease between Eruption 2 and Eruption 3: 74 - 70 = 4 minutes

Decrease between Eruption 3 and Eruption 4: 62 - 74 = -12 minutes

Decrease between Eruption 4 and Eruption 5: 80 - 62 = 18 minutes

From the calculations, we can see that the biggest decrease in waiting time occurs between Eruption 4 and Eruption 5, with a decrease of 18 minutes.

Therefore, the biggest decrease in waiting time between two consecutive eruptions is 18 minutes.

In order to assign the biggest decrease to the biggest decrease in waiting time between consecutive eruptions, calculate the difference in waiting times for each pair of eruptions, and the biggest decrease will be the largest difference you find.

To assign the biggest decrease to the biggest decrease in waiting time between two consecutive eruptions, you need to first identify the waiting times between each pair of consecutive eruptions. Then, calculate the difference in waiting times between each pair. For example, if the third eruption occurred after 74 minutes and the fourth after 62 minutes, the decrease in waiting time was 74 - 62 = 12 minutes. You repeat this process for all pairs of consecutive eruptions, and the biggest decrease in waiting time will be the largest difference you calculate.

To compare the different measurements, we need to convert them all to the same unit. Let's convert them to liters, which is a commonly used unit of volume.

4200 cm^3 = 4.2 liters (1 liter = 1000 cm^3)

54000 mm^3 = 0.054 liters (1 liter = 1,000,000 mm^3)

45 liters = 45 liters (already in liters)

52000 ml = 52 liters (1 liter = 1000 ml)

So the largest measurement is 52 liters, which corresponds to 52000 ml.

The price at which the video game should be sold to maximize profit is $19.40 (to the nearest cent).

We have,

To find the price at which the video game should be sold to maximize profit, we need to find the x-value that corresponds to the maximum value of y.

The equation that relates profit to selling price is:

y = -5x^2 + 194x - 990

To find the x-value that maximizes profit, we need to find the vertex of the parabolic graph represented by this equation.

The x-coordinate of the vertex is given by:

x = -b/2a

where a is the coefficient of the x^2 term, and b is the coefficient of the x term.

In this case,

a = -5 and b = 194, so:

x = -194/(2 (-5)) = 19.4

Thus,

The price at which the video game should be sold to maximize profit is $19.40 (to the nearest cent).

Given:

Initial savings in Katie's account = $230

Additional savings = $5 per month

To find:

The expression that represents the money Katie will have in her savings account after x months.

Solution:

Let x be the number of months.

Additional savings for 1 month = $5

Additional savings for x months = $5x

Now,

Total savings = Initial saving + additional savings for x months.

\(\text{Total savings}=230+5x\)

Therefore, the required expression is \(230+5x\).

To write the equation of a parabola given the vertex and focus, we can use the standard form of the equation for a parabola:

\((x - h)^2 = 4p(y - k)\)

where (h, k) represents the vertex coordinates and p represents the distance between the focus and vertex.

In this case, the vertex is (6, -3) and the focus is (6, -4). We can determine the value of p as the difference in the y-coordinates:

p = -4 - (-3) = -4 + 3 = -1

Substituting these values into the standard form equation, we have:

\((x - 6)^2 = 4(-1)(y - (-3))\)

\((x - 6)^2 = -4(y + 3)\)

Expanding the equation:

\((x - 6)^2 = -4y - 12\)

Therefore, the equation of the parabola with vertex (6, -3) and focus (6, -4) is:

\((x - 6)^2 = -4y - 12\)

Step-by-step explanation:

The correct answer is (c) normal distribution.

When comparing two proportions, the difference between them can be calculated, and its sampling distribution can be approximated by a normal distribution when the sample sizes are sufficiently large.

The mean of the sampling distribution is the difference between the true population proportions, and the standard deviation of the sampling distribution is calculated as:

\(sqrt[(p1*(1-p1)/n1) + (p2*(1-p2)/n2)]\)

where p1 and p2 are the population proportions, and n1 and n2 are the sample sizes.

Therefore, the sampling distribution of the difference between two proportions is approximated by a normal distribution with mean (p1-p2) and standard deviation given by the above formula.

The largest palindrome made from the product of two 3-digit numbers is 906609.

To find the largest palindrome made from the product of two 3-digit numbers, we can start by considering all possible products of two 3-digit numbers, ranging from 100 to 999. We can then check if each product is a palindrome.

A palindrome is a number that reads the same forwards and backwards. We can iterate through the products in decreasing order and check if each product is a palindrome. If we find a palindrome, we compare it with the current largest palindrome found and update it if necessary.

Starting from 999 and iterating downwards, we multiply each number by all the 3-digit numbers below it. For example, we multiply 999 by 999, 998, 997, and so on. We continue this process until we find the largest palindrome.

After checking all possible products, we find that the largest palindrome made from the product of two 3-digit numbers is 906609. This palindrome is obtained by multiplying 993 by 913.

Therefore, the largest palindrome made from the product of two 3-digit numbers is 906609.
