Answer:

a. area = 78.5

circumference = 31.4

b. area = 113.04

circumference = 37.68

Step-by-step explanation:

To find the area use:

Area = pi • r^2

They said to use 3.14 for pi.

Area = 3.14r^2

For part a, the diameter is given, 10. Radius is half of diameter. Radius is 5.

Area = 3.14•5^2

= 3.14•25

= 78.5

Same formula for area for part b. But the radius is given, 6.

area = 3.14•6^2

= 3.14 • 36

= 113.04

Circumference is

C = pi•d

part a the diameter is 10.

C = pi • 10

= 3.14 • 10

= 31.4

for part b, double the radius to find the diameter. Radius is 6, so diameter is 12.

C = pi • d

= 3.14 • 12

= 37.68

A) the centroid of the region is (1/4, 1/10).

A) To find the centroid of the region bounded by y=x^2 and x=y^2, we first need to find the intersection points of the curves.

Setting x=y^2, we get y=x^(1/2). Substituting this in y=x^2, we get x=x^4. Solving for x, we get x=0 or x=1.

So the region is bounded by the curves x=y^2, x=1, and y=0. To find the centroid, we need to evaluate the following integrals:

x-bar = (1/A) * ∫[0,1] ∫[0,√x] x*y dy dx

y-bar = (1/A) * ∫[0,1] ∫[0,√x] (1/2)*y^2 dx dy

where A is the area of the region, which we can find by integrating y=x^2 from x=0 to x=1:

A = ∫[0,1] x^2 dx = 1/3

Evaluating the integrals, we get:

x-bar = (1/3) * ∫[0,1] ∫[0,√x] x*y dy dx = 1/4

y-bar = (1/3) * ∫[0,1] ∫[0,√x] (1/2)*y^2 dx dy = 1/10

B) To sketch the region bounded by y=25−x^2 and y=0, we can start by plotting the y-axis and x-axis. Then, we can plot the curve y=25−x^2, which is a downward-facing parabola that intersects the x-axis at x=5 and has a maximum value of 25 when x=0. Finally, we can shade the region below the curve and above the x-axis to represent the region bounded by the curves.

        |  /          \

        | /            \

---------+------------------

        |0     5

```

C) To find the exact coordinates of the centroid, we can use the formula:

x-bar = (1/A) * ∫[a,b] ∫[0,f(x)] x*y dy dx

y-bar = (1/A) * ∫[a,b] ∫[0,f(x)] (1/2)*y^2 dx dy

where A is the area of the region, f(x) is the upper curve, and a and b are the x-coordinates of the intersection points.

In this case, the intersection points are x=0 and x=5. So the region is bounded by the curves y=25−x^2, y=0, x=0, and x=5. The area of the region can be found by integrating y=0 from x=0 to x=5:

A = ∫[0,5] 0 dx = 0

This doesn't make sense. It means that we made an error in setting up the integral. Looking back at the sketch, we see that we forgot to include the region between the x-axis and the curve y=25−x^2. So the area of the region is:

A = ∫[0,5] (25-x^2) dx = 125/3

Answer: Correct

Step-by-step explanation: Brainliest pls:)

Answer:

False

Step-by-step explanation:

The cube root of -8 can be simplified as follows:

\(\sqrt[3]{-8} =\sqrt[-3]{-1*2^3}\)

Since, \(\sqrt[3]{-1}=-1\) , we can write:

\(\sqrt[3]{-8} =-1* \sqrt[3]{8}\)

Then, we can factor out the cube root of 2 from 8 as follows:

\(\sqrt[3]{8} = \sqrt[3]{2^3}=2\)

Substituting this back into the original expression, we get:

\(\sqrt[3]{-8} =-1*2=-2\)

Therefore, the cube root of -8 can be simplified as -2, which is not equivalent to\(2\sqrt[3]{2}\)multiplied by -1. Hence, the statement "cube root of (-8) is reduced to\(2\sqrt[3]{2}\)" is false.

A major disadvantage of electron microscopes compared to light microscopes is that they cannot be used to view live specimens. Therefore, option B is the correct answer.

A major disadvantage of electron microscopes compared to light microscopes is that they cannot be used to view live specimens. This is because the electron microscope requires a vacuum environment to function properly, which would kill any live specimen. Additionally, electron microscopes can only see surface details and do not have a very high power of resolution. Lastly, electron microscopes can only be used by doctors or trained technicians, so they are not as widely available as light microscopes.

Therefore, option B is the correct answer.

The volume of the rectangular prism is 428,544 cubic cm.

To find the volume of the rectangular prism, we can start by determining the dimensions of the prism.

Let's assume the length, width, and height of the prism are L, W, and H, respectively.

Given that the rectangular prism is filled exactly with 248 cubes, we can express the total number of cubes as the product of the length, width, and height of the rectangular prism:

\(L \times W \times H = 248\)

Since each cube has an edge length of 12 cm, the volume of one cube can be calculated as follows:

Volume of one cube \(= (12 cm) \times (12 cm) \times(12 cm)\)

Volume of one cube \(= 1728 cm^3\)

Now, we can set up the equation based on the given information:

\(L \times W \times H = 248 \times Volume of one cube\)

\(L \times W \times H = 248 \times 1728 cm^3\)

To find the volume of the rectangular prism, we need to calculate the right side of the equation:

\(248 \times1728 = 428,544 cm^3\)

Therefore, the volume of the rectangular prism is \(428,544 cm^3\).

The system of equations that can represent the system is 4t+7b=28 and 5t+2b=28.50.

Given to us

Khalid bought 4 pounds of tomatoes and 7 pounds of broccoli for $28.

Genevieve bought 5 pounds of tomatoes and 2 pounds of broccoli for $28. 50.

Let t represent the cost of one pound of tomatoes.

Let b represent the cost of one pound of broccoli.

We know that the cost of a pound of tomatoes is t while for one pound of broccoli it is b. therefore,

4 pounds of tomatoes + 7 pounds of broccoli = $28

4(t) + 7(b) = 28

4t + 7b = 28

We know that the cost of a pound of tomatoes is t while for one pound of broccoli it is b. therefore,

5 pounds of tomatoes + 2 pounds of broccoli = $28.50

5(t) + 2(b) = 28.50

Alex can make a total of 180 different sandwiches by choosing one kind of meat from 10 options and two kinds of cheese from 9 options.

To determine the number of different sandwiches Alex can make, we need to consider the combinations of meat and cheese. Since Alex can choose one kind of meat from 10 options, there are 10 choices for the meat component of the sandwich. For the cheese component, Alex can choose two kinds of cheese from 9 options.

To calculate the total number of combinations, we can use the formula for combinations without repetition. The formula is nCr = n! / (r!(n-r)!), where n is the total number of options and r is the number of choices. In this case, n is 9 (number of cheese options) and r is 2 (number of cheese choices). Thus, the number of combinations of two kinds of cheese is \(9C2\)= 9! / (2!(9-2)!) = 36.

To solve this problem, we need to find the x-values where the curve intersects the x-axis, which occurs when y=0.
0=x²-2kx ,We can factor out an x: 0=x(x-2k) .So the x-intercepts are at x=0 and x=2k.

To find the value of k, we need to follow these steps:

Step 1: Find the points of intersection between the curve y = x^2 - 2kx and the x-axis.
To do this, set y = 0:
0 = x^2 - 2kx
x(x - 2k) = 0

This means that the curve intersects the x-axis at x = 0 and x = 2k.

Step 2: Determine the limits of integration.
Since we are looking for the region in the fourth quadrant, we will have limits 0 and 2k for our integration.

Step 3: Calculate the area using integration.
Area = ∫[0 to 2k] (x^2 - 2kx) dx

Step 4: Solve the integral.
Area = [1/3x^3 - kx^2] evaluated from 0 to 2k
Area = (1/3(2k)^3 - k(2k)^2) - (1/3(0)^3 - k(0)^2)
Area = (8k^3/3 - 4k^3)

Step 5: Set the area equal to 36 and solve for k.
36 = 8k^3/3 - 4k^3
36 = (8k^3 - 12k^3)/3
36 = -4k^3/3

Now, multiply both sides by 3 and divide by -4:
-108/-4 = k^3
27 = k^3

Take the cube root of both sides:
k = 3

The value of k is 3 (Option b).

Answer:

Below in bold.

Step-by-step explanation:

We have a right triangle here with the hypotenuse = 2 and the legs are 1 and √3.

If tan A > 0 then the opposite side to < A  in the triangle is greater than the adjacent so the leg opposite angle A is √3 and the adjacent side = 1.

So cos A = adj/hyp = 1/2.

The equation of the quadratic function C(t) is given as follows:

C(t) = t² - 8t + 16.

The equation of a quadratic function has the format given as follows:

y = a(x - x')(x - x'')

In which:

From the points repeating(C(t) = 1 at t = 3 and t = 5, C(t) = 4 at t = 2 and t = 4), we have that the root of 4, as C(4) = 0, has multiplicity 2, hence:

x' = x'' = 4.

Hence:

y = a(x - 4)(x - 4)

y = a(x² - 8x + 16)

When t = 3, C(t) = 1, hence the leading coefficient a is obtained as follows:

1 = a(3² - 8(3) + 16)

a = 1

Hence the function is given by:

C(t) = t² - 8t + 16.

When the number 410 is changed to 310 in the list of student numbers for the 10 schools in the district:

(a) The mean increases by 0.9.

(b) The median decreases by 7.

(a) The mean is calculated by summing up all the values and dividing by the total number of values.

Let's compare the mean before and after the change in the number 410.

Before the change:

Mean = (170 + 194 + 303 + 309 + 316 + 330 + 368 + 371 + 379 + 410) / 10 = 308

After the change (410 changed to 310):

Mean = (170 + 194 + 303 + 309 + 316 + 330 + 368 + 371 + 379 + 310) / 10 = 308.9

Comparing the mean before and after the change, we can see that the mean increases by 0.9.

(b) The median is the middle value of a sorted dataset. In this case, the median is the value that separates the lower half from the upper half when the numbers are arranged in ascending order.
