The relationship between the plane and the cone is expressed by the statement that it is parallel to the base of the cone.

Given,

A circle is a closed, curved shape with two dimensions in geometry, alternatively we might say that a circle is a spherical form without borders or edges.

When a cone is cut by a plane that is parallel to the cone's base, a circle is the resultant cross-section.

The form that results from a plane cutting a cone at an angle such that it misses the base or the vertex is called an ellipse. (As in the figure.)

Hence When a plane cuts through a cone and the plane is parallel to the base of the cone, the result is a circle.

The amount of pure acid in the solution is 109.2ml. The solution has been obtained using the concept of proportion.

What is proportion?

When a ratio is expressed as a/b and two ratios are equal, the expression is a proportion. A and B can be any two integers in this case. Understanding many ideas in mathematics and science requires a solid understanding of ratios and proportions.

According to the direct proportion formula, we can state y = kx given a constant k if the quantity y is directly proportional to the quantity x. The direct proportion equation also has a generic form, which is y = kx.

Let 'x' ml be the quantity of pure acid in the solution.

We are given that we have 780 ml of a 14% solution

This means that 780ml is 100%.

So, using proportion:

⇒780/x= 100/14

⇒780*14/100=x

⇒109.2ml = x

Hence, the amount of pure acid in the solution is 109.2ml.

Positively Skewed: A positively skewed distribution is one that has a long tail in the positive direction (to the right).

The mean is usually greater than the median, and the data points are concentrated on the left side of the graph. To calculate the skewness of a distribution, we use the formula: skewness = (mean – median) / standard deviation. In the case of the histogram, the mean is greater than the median, and the skewness is therefore positive.

Symmetric: A symmetric distribution is one that is perfectly centered around the mean and has equal amounts of data points on either side of the mean. In the histogram, the data points are not perfectly centered around the mean, so this term does not apply.

Uniform: A uniform distribution is one that has all the data points clustered around the same value. In the case of the histogram, the data points are spread out across a wide range, so this term does not apply.

Unimodal: A unimodal distribution is one that has a single peak. In the case of the histogram, the data points are spread out across a wide range, so this term does not apply.

So, the correct option is (c) 18.

Given that,

   Jeremy has two pieces of  90 inches and the other is 72 inches wood. He wants to cut both pieces of wood into smaller pieces of same length and length as long as possible.

Therefore, the Highest Common Factor (H.C.F.) of both the lengths will gives the highest possible length i.e between both the wooden pieces.

To find Highest Common factor,

Prime factorizations of 90 and 72 :

90 = (2 x 3 x 3) x 5

72 = 2 x 2 x (2 x 3 x 3)

2 x 3 x 3 is common factor between 90 and 72

∴ The  Highest Common Factor of 90 and 72 = 2 x 3 x 3 = 18

The longest possible length that can be cut out from both the  pieces are of length = 18 inches

Number of pieces that can be cut from 90 inches long piece = 90/18 = 5

Because the angle has a bisector ON, we should be able to add the angles together to collectively equal 106. This will help us to find c, so then we can solve <LOM.

(10c-23) + (-3c+73) = 106

Now combine like terms of the left side of the equation

7c + 50 = 106

get the variables alone on one side of the equation

7c = 56

c = 8

Now, plug in c to the equation for the degree of <LOM to solve

What is velocity?

The pace at which an object's position changes in relation to a frame of reference and time is what is meant by velocity. Although it may appear sophisticated, velocity is just the act of moving quickly in one direction.

The velocity of a free-falling rock can depicted by equation of motion.

The first equation of motion, v = u + it is referred to as the velocity-time relation. On the other hand, the second equation of motion is s = ut + 1 / 2at² can be called the position-time relation. Likewise, we call the third equation of motion, v² = u²+ 2as, position – velocity relation.

The laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object's mass. (3) For every action, there is an equal and opposite reaction.

Since, the rock is falling freely it will form a straight line (first equation of motion) on the graph and not curved.

The rock will start to fall at an increasing speed with respect to time.

The Fundamental Theorem of Calculus (FTC) has two parts: Part 1 and Part 2.

Part 1 (The Antiderivative Part) states that if f is a continuous function on an interval [a, b], then there exists an antiderivative F of f on [a, b], meaning that F'(x) = f(x) for all x in [a, b].

This means that given a function, we can find a new function that when differentiated, returns the original function.

Part 2 (The Evaluation Part) states that if F is an antiderivative of f on [a, b], then the definite integral of f over [a, b] can be calculated as the difference of the values of the antiderivative F evaluated at the endpoints, i.e., ∫_a^bf(x)dx = F(b) - F(a).

This means that we can evaluate the definite integral of a function by finding its antiderivative and evaluating it at the endpoints of the interval.

Part 1 is used to find antiderivatives, while Part 2 is used to evaluate definite integrals. They are complementary and are used in tandem to solve problems involving integration.

A real-world example that involves Part 2 of the FTC is the calculation of the total distance traveled by a moving object. If the velocity of the object is given as a function of time, we can use the FTC to calculate the total distance traveled by finding the definite integral of the velocity function over the time interval and evaluating it at the endpoints. The result is the difference between the final and initial positions of the object.
