two solid sphere Have volume 250 cm^3and 128 cm ^3 respectively find the ratio of the air Radii(wASSCE)​

Answer:

210m²

Step-by-step explanation:

We have 2 triangular faces with surface 5m*12m/2 = 30m² each

We have the top face with surface 5m*12m = 60m²

We have the bottom face with surgace 5m*13m = 65m²

And we have the "middle" with surface 5m*5m = 25m²

For a total of

30m² + 30m² + 60m² + 65m² + 25m² = 210m²

To dilate from the Y axis, you would use a transformation matrix with a scale factor of 1 for the X axis and a scale factor greater than 1 for the Y axis. For example, if you wanted to scale up by 2, the transformation matrix would look like this:

[1, 0]

[0, 2]

1. Begin by defining the point P(x, y) that you want to dilate.

2. Create a transformation matrix with a scale factor of 1 for the X axis and a scale factor greater than 1 for the Y axis. For example, if you wanted to scale up by 2, the transformation matrix would look like this:

[1, 0]

[0, 2]

3. Multiply the point P by the transformation matrix to obtain the new point P'(x', y'). For example, for the point P(2, 3) and the transformation matrix above, the new point P' would be P'(2, 6).

4. The new point P' is the result of dilating from the Y axis.

Option D is correct, the population variance is 16.

Given that  a population of N = 100 scores has mean µ = 30 and standard deviation σ = 4.

We have to find the  population variance.

The population variance (σ²) is calculated as the square of the standard deviation (σ).

In this case, since the standard deviation (σ) is given as 4, we can find the population variance as follows:

Population variance (σ²) = (Standard deviation)²

= 4²

= 16.

Therefore, the population variance is 16. Hence, the correct option is D) 16.

The value of the t score for a 98% confidence interval when taking a sample of size 20 is 2.861.

The value of the t score for a 98% confidence interval when taking a sample of size 20 is 2.861. This calculation is based on the t-distribution, which is a probability distribution that is used to calculate confidence intervals. The t-distribution is used when the population standard deviation is unknown and the sample size is relatively small, which is the case for our sample size of 20. To calculate the t score, we need to first calculate the degrees of freedom, which is equal to n-1 = 20-1 = 19. Then, use this value of degrees of freedom to look up the relevant t score in a t-table. This will give us a t score of 2.861. This t score indicates the level of confidence that our sample mean is representative of the population mean. Therefore, when taking a sample of size 20 and calculating a 98% confidence interval, the t score we get is 2.861.

Primitive data types are the most basic data types. They include boolean, character, integer, floating-point, and void values. Boolean values are either true or false, while character values are single characters. Integer values are whole numbers, while floating-point values are fractional numbers. Void values indicate that no value is present.

Composite data types are composed of other data types, such as arrays, records, and classes. Arrays are collections of data elements that can be of any data type. Records are collections of related data elements, such as student records consisting of a name, address, and phone number. Classes are collections of data elements and related functions that can be used to create objects.

Derived data types are those that are derived from other data types, such as pointers, references, and enumerations. Pointers are variables that store the memory address of another variable. References are similar to pointers in that they point to the memory location of another variable, but they do not require the use of the asterisk operator.

Answer:Sorry

Step-by-step explanation:

The equation is f ( - x ) = 2x⁴ + x² + 5 and f ( x ) = f ( - x )

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

f ( x ) = 2x⁴ + x² + 5   be equation (1)

On simplifying the equation , we get

When the value of x = -x

Substitute the value of x = -x in the equation , we get

f ( - x ) = 2 ( -x )⁴ + ( - x )² + 5

On further simplification , we get

f ( - x ) = 2 ( x )⁴ + ( x )² + 5

So ,

f ( - x ) = 2x⁴ + x² + 5 = f ( x )

Therefore , the value of f ( - x ) = 2x⁴ + x² + 5

The solution to the system of equations from the graph and the algebraic method correlates with one another i.e. x = 4, y = 3

A system of linear equations is a grouping of one or more linear equations with the same variables. There are various ways for solving a system of two linear equations, these includes:

In the Graphical method, to graph an equation system, we simply do so by plotting the equations on the same set of axes and searching for the point(s) where the two lines cross. This intersection point is the system's solution since it reflects the values of the variables that make both equations true at the same time.

The plot for the two systems of the equation can be seen in the image attached below.

y = x - 1

y = 3x - 9

From the graph, we could see that the two equations intersect at (4,3). It implies that in the order (x,y), x = 4, and y = 3.

Using the algebra elimination method.

y = x - 1          ..... (1)

y = 3x - 9       ..... (2)

From equation (1),

y - x =  -1

y - 3x =  -9

By Elimination method,

2x = 8

x = 8/2

x = 4

Replace the value of x into equation (1),

y = 4 - 1

y = 3

Therefore, we can conclude that the solution to the system of equations from the graph and the algebraic method correlates with one another i.e. x = 4, y = 3

Here we want to solve the equation below:

2.3 × 10^9 = (1 × 10^3)(2.3 × 10^n)

For the exponent n.

To fo so, we can start by dividing both sides by the first factor on the right side.

2.3 × 10^9 = (1 × 10^3)(2.3 × 10^n)

(2.3× 10^9)/(1 × 10^3) = 2.3 × 10^n

Remember the quotient between powers of the same base:

a^n/a^m = a^{n - m}

Then we will get:

(2.3× 10^9)/(1 × 10^3) = 2.3 × 10^n

(2.3/1)×(10^9/10^3) = 2.3 × 10^n

Now we can use the property written above:

Answer:

The slope of a line is given by the formula "rise over run," or (y2 - y1)/(x2 - x1). In this case, the rise is 7 - 6 = 1, and the run is 4 - p.

So the slope is equal to 1/(4 - p). We are told that this slope is equal to j, so we can set up the equation:

1/(4 - p) = j

To solve for p, we can multiply both sides of the equation by (4 - p) to get:

(4 - p) = j(4 - p)

Then we can simplify the left side and rearrange the terms on the right side to get:

4 - p = 4j - jp

Then we can add p to both sides to get:

4 = 4j - jp + p

Then we can combine like terms to get:

4 = (4 - p)j + p

Then we can rearrange the terms to solve for p:

p = 4 - (4 - p)j

p = 4 - 4j + pj

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

p(1 - j) = 4 - 4j

p = (4 - 4j)/(1 - j)

This is the value of p that will make the slope of the line with points (p, 6) and (4, 7) equal to j.

If you know the value of x, you can substitute it into the equation and get the perimeter of the larger triangle.

What is the equilateral triangle?

An equilateral triangle is a type of triangle in which all three sides have the same length. The three angles in an equilateral triangle are also congruent and measure 60 degrees each. This means that all the angles in an equilateral triangle are always equal to 60 degrees. An equilateral triangle can also be referred to as an equiangular triangle.

The diagram shows two proportional right triangles, with triangle ABC and triangle DEF.

We know that AB = 6, AC = 10, and BC = 8 for triangle ABC, and EF = 16 for triangle DEF.

Since the two triangles are similar and proportional, the ratio of the corresponding sides is the same for both triangles.

We know that AB/EF = AC/EC = BC/DE

Since we know that AB = 6 and EF = 16, we can calculate the value of DE (the length of the hypotenuse of the larger triangle) using the proportion:

6/DE = 16/x

We can solve for DE by multiplying both sides by x:

DE = 16 * 6 / x

Now we can calculate the perimeter of the larger triangle by adding the lengths of all three sides:

Perimeter = DE + DE + 16 = (16 * 6 / x) + (16 * 6 / x) + 16

However, if you know the value of x, you can substitute it into the equation and get the perimeter of the larger triangle.
