Two straight lines or rays intersect at a same terminus to make an angle. The vertex of an angle is the point at which all points meet. Two rays (half-lines) combined into an angle have a single terminal. The latter is known as the vertex of the angle, while the rays are known as its sides, occasionally as its legs, and occasionally as its arms.

An angle is a figure created by two rays or lines that have the same termination in plane geometry. The Latin word "angulus," which meaning "corner," is where the term "angle" originates. The common terminal of the two rays—known as the vertex—is referred to as an angle's sides.

(x-1)^3.

Step-by-step explanation:

To find the least common multiple (LCM) of two polynomials, you can factor them and take the highest exponent of each variable that appears. In this case, the LCM is (x-1)^3 because it has the highest exponent of x that appears in both polynomials. It also contains all the other terms of both polynomials.

Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty. A probability is a numerical representation of the likelihood or likelihood that a particular event will occur. Alternative ways to express probabilities are as percentages from 0% to 100% or from 0 to 1. the percentage of occurrences in a complete set of equally likely possibilities that result in a certain occurrence compared to the total number of outcomes.

x = number that drive to work alone

Likelihood that exactly eight people drive alone to work is equal to the probability that no more than seven people drive alone.

The rate at which the level in the pot is rising at the instant when the coffee in the pot is 10 cm, is 16/9π cm/min.

A cylinder is a three-dimensional solid in mathematics that maintains, at a given distance, two parallel bases connected by a curving surface.

For cylindrical pot,

Volume, V = πr²h

dV/dt = π(r²dh/dt+h * 2r dr/dt)

Since r is constant,

Therefore, dr/dt = 0

dV/dt = 100 = πr²dh/dt

100 = π * 225/4 *dh/dt (since r = 15/2 cm)

=> dh/dt = 400/ 225π = 16/9π cm/min.

Thus, The rate at which the level in the pot is rising at the instant when the coffee in the pot is 10 cm, is 16/9π cm/min.

The bearing of H from P is 243°26′

In mathematics, an angle is a measure of the amount of rotation between two lines or planes. It is measured in units of degrees or radians. An angle is formed by two rays that have a common endpoint called the vertex. The rays are the sides of the angle and the vertex is the point where the rays meet.

An angle is defined by its measure, which is the amount of rotation between the two rays. The most common way to measure angles is in degrees, where a full rotation is equal to 360 degrees. Another way to measure angles is in radians, where a full rotation is equal to 2*pi radians.

Let the bearing of H from P be represented by x°.

tanθ=3060=0.5

θ=tan−1(0.5)=26.565°

x=180°+(90−26.565)

x=180+63.435=243.435°

= 243°26′

Hence, the bearing of H from P is 243°26′

Answer:

70⁰ is the correct answer.

Answer:

Step-by-step explanation:

So you add 1+3+7 which gives you 11

And the you divide 3300 by 11 which gives you 300 and from that you do:

1 x 300= 300

3 x 300= 900

7 x 300= 2100

And there you have it in the ratio of 1:3:7

300:900:2100

And to simplify it you find a number which you can divide them all from in this case is 100 and so:

300÷100=3

By applying the first derivative of distance with respect to time, it can be concluded that the person is walking 4/3 meters per second.

Instantaneous velocity or rate is the first derivative of distance with respect to time. Mathematically it is written v = ds/dt, where v is the velocity, s is the distance and t is the time.

First, we make a simple drawing using the given information:

The walking person = 2 meters tall

The street light = 8 meters above the ground

The walking rate is constant

The person's shadow lengthening rate = 4/9 meter per second = dy/dt

We want to know the walking rate, dx/dt.

We determine the value of y:

8 / 2 = (x + y) / y

  8y = 2x + 2y

  6y = 2x

    y = x / 3

Then we substitute the value of y into the equation:

dy/dx = d(x/3) / dx

         = 1/3

Finally, we can get the rate dx/dt:

dx/dt = dy/dt * dx/dy

         = 4/9 * 3

         = 4/3

Thus, it can be concluded that the person is walking 4/3 meters per second.

A multiple integral in mathematics is a definite integral of a function with multiple real variables, such as f(x, y), or f(x, y) (x, y, z). In the real-number plane, integrals of functions of two variables over an area are referred to as double integrals, and integrals of functions of three variables over a region in real-number three-dimensional space are referred to as triple integrals.

The Cauchy formula for repeated integration can be used to calculate multiple integrals of a single-variable function.

The double integral of a positive function of two variables represents the volume of the region between the surface defined by the function (on the three-dimensional Cartesian plane where z = f(x, y)) and the plane that contains its domain, just as the definite integral of a positive function of one variable represents the area of the region between the graph of the function and the x-axis.

The midsegments of AABC, hypotenuse BC  is B. 15.

In a triangle, a midsegment is a line segment that connects the midpoints of two non-adjacent sides of the triangle. In this figure, DE and DF are the midsegments of AABC, which means that they connect the midpoints of the sides AB and AC, respectively. Since DE and DF are parallel, we know the triangle isosceles (both legs are congruent).

Since the angle at A is 122°, we know that the angle at B and C are 78° (180-122=58). Therefore, if we draw the altitude from B to AC, we have a 30-78-72 triangle. We have been given the length of the altitude, 8, and the angle of the base, 72. We can use the Sine Ratio to calculate the hypotenuse, BC.

sin(72) = opposite / hypotenuse = 8/BC

the height of six glasses (24 / 6 = 4). Finally, we can multiply this by six to get the final answer, which is 30 cm.

30 cm

For two glasses, the height is 18 cm.

For eight glasses, the height is 42 cm.

Therefore, for six glasses, the height would be (42 - 18) / (8 - 2) * 6 = 30 cm.

To answer the question, we need to first determine the height of two glasses, which is 18 cm. Next, we need to find the height of eight glasses, which is 42 cm. Once we have these two values, we can calculate the height of six glasses. We can do this by finding the difference between the two heights (42 - 18 = 24), which will give us the height of six glasses (24 / 6 = 4). Finally, we can multiply this by six to get the final answer, which is 30 cm.

The formula for work is force multiplied by displacement.

Work done refers to the amount of energy used by a force to move an object. It is also a physical quantity. Its SI unit is Joule. Every time a force is applied to an object and it moves from one location to another, work has been done. The displacement is what needs to be taken into account and not the distance. Displacement is the smallest distance or straight line that connects the object's initial and final positions. Work is therefore equivalent to force times its displacement. Force is measured in newtons, and the displacement is measured in meters. Therefore, if a force of 1N is used to move a body by a displacement of 1m, then 1J of work has been completed.
