Consider the function f (x) = 3x2 - 4x + 6. = What is the right rectangular approximation of the area under the curye of f on the interval [0, 2] with four equal subintervals? Note: Round to the neare
Rounding the final result to the nearest decimal point, the approximate area under the curve of f(x) on the interval [0, 2] using the right rectangular approximation with four equal subintervals is approximately 12.3.
To approximate the area under the curve of the function f(x) = 3x² - 4x + 6 on the interval [0, 2] using a right rectangular approximation with four equal subintervals, we can follow these steps:
1. Divide the interval [0, 2] into four equal subintervals. The width of each subinterval will be (2 - 0) / 4 = 0.5.
2. Calculate the right endpoint of each subinterval. Since we're using a right rectangular approximation, the right endpoint of each subinterval will serve as the x-coordinate for the rectangle's base. The four right endpoints are: 0.5, 1, 1.5, and 2.
3. Evaluate the function f(x) at each right endpoint to obtain the corresponding heights of the rectangles. Plug in the values of x into the function f(x) to find the heights: f(0.5), f(1), f(1.5), and f(2).
4. Calculate the area of each rectangle by multiplying the width of the subinterval (0.5) by its corresponding height obtained in step 3.
5. Add up the areas of all four rectangles to obtain the approximate area under the curve.
Approximate Area = Area of Rectangle 1 + Area of Rectangle 2 + Area of Rectangle 3 + Area of Rectangle 4
Note: Since you requested rounding to the nearest, please round the final result to the nearest decimal point based on your desired level of precision.
To calculate the right rectangular approximation of the area under the curve of the function f(x) = 3x² - 4x + 6 on the interval [0, 2] with four equal subintervals, let's proceed as described earlier:
1. Divide the interval [0, 2] into four equal subintervals: [0, 0.5], [0.5, 1], [1, 1.5], [1.5, 2].
2. Calculate the right endpoints of each subinterval: 0.5, 1, 1.5, 2.
3. Evaluate the function f(x) at each right endpoint:
f(0.5) = 3(0.5)² - 4(0.5) + 6 = 2.75
f(1) = 3(1)² - 4(1) + 6 = 5
f(1.5) = 3(1.5)² - 4(1.5) + 6 = 6.75
f(2) = 3(2)² - 4(2) + 6 = 10
4. Calculate the area of each rectangle:
Area of Rectangle 1 = 0.5 * 2.75 = 1.375
Area of Rectangle 2 = 0.5 * 5 = 2.5
Area of Rectangle 3 = 0.5 * 6.75 = 3.375
Area of Rectangle 4 = 0.5 * 10 = 5
5. Add up the areas of all four rectangles:
Approximate Area = 1.375 + 2.5 + 3.375 + 5 = 12.25

Madison is making a place mat. She divides it into 6 equal parts to colors. What is the name for the parts?
Answer:
6
Step-by-step explanation:
Based on the information given if She divided the place mat into 6 equal parts to color the name for the parts will be the 6 parts she divided to color reason been that division or separation of the place mat into 6 equal Parts to color means that the place mat that was divided by Madison into 6 equal parts have the same size or equal size .
Therefore the name for the parts will be 6.
When we divide a shape with each part has same size then all the parts are called as equal parts of a whole. Thus the name of equal parts of the mat made by the Madison is sixths.
Equal parts of a whole-
When we divide a shape with each part has same size then all the parts are called as equal parts of a whole.
For example, a shape is divided into two equal parts then the name of the equal parts is halves. If a shape is divided into three equal parts then the name of the equal parts is thirds.
Here in the question, given-
The mad made by the Madison has 6 part.
The size and shape of each part is same.
When Madison divides the mat in 6 equal part of this mat than each part will have 1/6 part mat of the original size mat. As by the definition of the equal parts of a whole we can conclude that if a shape is divided into 6 equal parts then the name for the parts is sixths.
Hence, the name of equal parts of the mat made by the Madison is sixths.

uppose the probability of an unsuccessful missile launch is 0.3. If missiles continue to be launched until an unsuccessful launch occurs, what is the probability that exactly 4 total launches will be performed (round off to first decimal place)
The probability that exactly 4 total launches will be performed until an unsuccessful launch occurs is approximately 0.0720 or 7.2%
The probability of exactly 4 total launches being performed until an unsuccessful launch occurs, we can use the geometric probability formula.
In this case, the probability of a successful launch (p) is 0.7 (since the probability of an unsuccessful launch is 0.3). We want to find the probability of 4 successful launches followed by an unsuccessful launch.
The probability of exactly 4 successful launches followed by an unsuccessful launch can be calculated as follows:
P(4 successful launches followed by an unsuccessful launch) = (p⁴) × (1-p)
P(4 successful launches followed by an unsuccessful launch) = (0.7⁴) × (1-0.7)
P(4 successful launches followed by an unsuccessful launch) = 0.7⁴ × 0.3
P(4 successful launches followed by an unsuccessful launch) = 0.2401 × 0.3
P(4 successful launches followed by an unsuccessful launch) ≈ 0.0720
Therefore, the probability that exactly 4 total launches will be performed until an unsuccessful launch occurs is approximately 0.0720 or 7.2%

sonia is walking in south direction after walking for 45 meters she takes a right turn and walks for another 28 meters she is at a distance of ____ meters from starting point
Answer:
53
Step-by-step explanation:
This is a nice pythagorean theorem practice question.
The pythagorean theorem is (not my definition): the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse
or otherwise known as: a^2 + b^2 = c^2
Taking a visual approach, if Sonia walks south 45 meters, the first leg will be 45 meters. Then she takes a left 28 meters, which is the second leg. Now you find the squares of those numbers and add them
45^2, or 45*45 is 2025
28^2, or 28*28 is 784
Now you add 2025 and 784 and find the square root.
2025+784 is 2809. Square root of 2809 is 53.

there are 25 students in a class. ignoring the year of birth, what is the probability that three of them were born in the same month?
Probability that three of them were born in the same month is 8.8737104e-21.
Total students present in class = 25.
What is the probability such that three of them were born in the same month?
Numerous applications can be made of the mathematical computation of probability. Probability can be used, for instance, to forecast sales growth or to estimate the likelihood that a particular marketing strategy would be successful in attracting new clients. The probability of something happening can also be calculated using mathematical formulas.
The probability that an event will occur is determined by probability:
P(A) = f / N = favourable outcomes/ total number of outcomes.
Probability and odds are related, but probability determines what the odds are. Probability is required before calculating the likelihood of an event.

total sample space for 25 students = 12^25

The figure shows the layout of a symmetrical pool in a water park. What is the area of this pool rounded to the tens place
The area of the pool is 600 square units rounded to the tens place.
The area of the symmetrical pool in the water park can be determined by finding the product of its length and width. From the given figure, it appears that the length of the pool is approximately 30 units and the width is approximately 20 units.
To find the area, we multiply the length and width:
Area = length × width
Area = 30 units × 20 units
Area = 600 square units
Rounding to the tens place means we want to round the area to the nearest multiple of 10. In this case, the area of 600 square units would round to 600.
Therefore, the area of the pool rounded to the tens place is 600 square units.
To summarize:
- The length of the pool is approximately 30 units.
- The width of the pool is approximately 20 units.
- The area of the pool is 600 square units rounded to the tens place.

Answer:
C
Step-by-step explanation:
Put x as 4.
4 + 8 = 3(4)
12 = 12
True.
The equation that has the solution x = 4 is x + 8 = 3x.
Given that,
The x = 4.Based on the given options,
(a) 4x = 20
Now if we put x value in the equation
Put x as 4
So
4x = 20
4(4) = 20
8 = 20
(b)
x ÷ 2 = 8
4 ÷ 2 = 8
2 = 8
(c)
x + 8 = 3x
(4) + 8 = 3(4)
12 = 12
Therefore we can conclude that the equation that has the solution x = 4 is x + 8 = 3x.
