Question 9 of 10 What is the scale factor of ABC to DEF? ​

The definite integral of a continuous function on an interval [a, b] represents the area under the graph of the function within that interval. It provides a mathematical way to measure the accumulation of change of the function over that interval.

The definite integral of a function f on the interval [a, b] is denoted by ∫f(x)dx over the interval [a, b]. This integral can be approximated by dividing the interval [a, b] into smaller subintervals and calculating the area under the graph of the function over each subinterval. The smaller the subintervals, the closer the approximation will be to the actual definite integral.

The definite integral is said to be a limit, meaning that as the size of the subintervals approaches zero, the sum of the areas under the graph over each subinterval approaches a definite value, which is the definite integral.

In mathematical terms, for each positive number e, there exists a positive number δ such that if the subintervals have width less than δ, then the difference between the sum of the areas under the graph and the definite integral will be less than e. This means that the definite integral provides a precise value for the area under the graph of the function over the interval [a, b].

15*80%=12$ dollars he sold it for her

(multiply by 80% because he lost 20%)

12*120%=14.40$  she sold it

(multiply by 120% because she made 20% more than 100%- regular price )

Step-by-step explanation:

Barbara pay 12$ dollars. Barbara later sold the DVD. She pay 14.40 dollars.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given; Ahmed bought a DVD for $15. He sold it to Barbara, making a 20% loss.

We need to find that how much did Barbara pay for it.

Barbara later sold the DVD. she made 20% profit and how much did She pay for it.

a) Now, multiply by 80% because he lost 20%.

15 x 80%

15 x 0.8 = 12$ dollars

b) Now, multiply by 120% because she made 20% more than 100%- regular price.

12 x 120%

12 x 0.12 = 14.40$

Barbara pay 12$ dollars. Barbara later sold the DVD. She pay 14.40 dollars.

By using trigonometry, it can be calculated that- sin 23º = \(\frac{5}{13}\)

What is Trigonometry?

Trigonometry is a branch of mathematics that studies the relationships between the sides and angles of triangles. It is used to calculate the lengths of sides, the measures of angles, and the relationships between the two. Trigonometry is important for understanding many areas in mathematics, such as calculus and engineering. Trigonometric functions are used to model and analyze phenomena in many areas, such as sound waves, light waves, and ocean tides. Trigonometric identities allow us to simplify equations and solve problems. Trigonometry is a fundamental tool in many scientific and engineering disciplines.

There are six trigonometrical functions. They are

\(sin\theta, cos\theta, tan\theta, cot\theta, sec\theta, cosec\theta\)

\(sin\theta = \frac{perpendicular}{hypotenuse}\\cos\theta = \frac{baser}{hypotenuse}\\tan\theta = \frac{perpendicular}{base}\\cot\theta = \frac{base}{perpendicular}\\sec\theta = \frac{hypotenuse}{base}\\cosec\theta = \frac{hypotenuse}{perpendicular}\\\)

Trigonometry is a very important tool in mathematics.

For an angle of 23º,

Perpendicular is 5, base is 12 and hypotenuse is 13

sin 23º = \(\frac{5}{13}\)

First option is correct.

This is the first stage of the two stage process which maps put all the timings.  What you do is this:

Add up all the times as you go from start to finish, so if the first task has a duration of, say 4 weeks and the second one takes, say, 7 weeks, then the earliest start date of the first one is after zero weeks (so you put a zero in the top left corner of it's box) and the earliest start of the second one is after 4 weeks, so you put in a 4.  On the third task you put 11 because that's the earliest you could start it, you can't do it sooner than that.  It's just adding up. The largest total from the various routes is the Critical Path.

Things get interesting when you then do the backward pass, ie the same but from the finish, taking the numbers off the critical path total.  So if the total came to 50 weeks and the last task was 4 weeks long you would put 44 in the bottom left corner - it must be started by then, so that's the latest start.

On the critical path the earliest and latest starts are the same, but on the floating tasks they will be different.  The difference between them is how much float you have for that task - how much it can move and still not hold up the project.

The earliest and latest finish (put in the right hand corners) are the same as the starts but with the duration added.  So in my example that I started with, EF is 4 for the first task, and 11 for the second.  and during the backward pass the LF for the last task is 50.

Answer:

Step-by-step explanation:

We will denote the almirahs as A1 and A2 for ease of explanation. I am omitting currency until the final answer

For the following computations note that x% = x/100 in decimal so
15% = 15/100 = 0.15
13 1/3% = 13 1/3 ÷ 100 = 40/3 ÷ 100 = 40/300

Cost of A1 = 4800

A1 was sold for a loss of 15%

Loss = 15% of 3640 = 0.15 x 3640  = Rs 546

A2 bought at 4800 was sold at a gain of 13 1/3%

Gain from sale = 13 1/3% of 4800 = 40/300 x 4800 =Rs 640

We have to treat gain as positive and loss as negative to arrive at the answer

Net gain/loss = 640  - 546 = Rs. 94

Answer:

Solution,

First term (a) = 25

Common difference (d) = Second term - first term = 20 - 25 = -5

Now,

nth term = a + (n - 1)d = 25 + (n - 1) (-5) = 25 - 5n +5 = 30 - 5n

The nth term of the series is 30 - 5n

Answer:

The nth term will be:

\(a_n=-5n+30\)

Step-by-step explanation:

Given the sequence

25, 20, 15, 10, 5​

An Arithmetic sequence has a constant difference 'd' and is defined by

\(a_n=a_1+\left(n-1\right)d\)

Computing the common difference of all the adjacent terms

\(25,\:20,\:15,\:10,\:5\)

\(20-25=-5,\:\quad \:15-20=-5,\:\quad \:10-15=-5,\:\quad \:5-10=-5\)

As the difference between all the adjacent terms is the same and equal to

\(d=-5\)

Also, the first term is:

\(a_1=25\)

Hence, the nth term will be:

\(a_n=a_1+\left(n-1\right)d\)

\(a_n=-5\left(n-1\right)+25\)        ∵ \(a_1=25\), \(d=-5\)

\(a_n=-5n+30\)

Therefore, the nth term will be:

\(a_n=-5n+30\)

Pythagoras - Has a theorem named after him

Thales - Contributed to the five basic theorems of geometry

Pythagoras was a Greek philosopher, mathematician, and founder of the Pythagorean school of philosophy. He lived in the 6th century BCE on the Greek island of Samos and is known for his contributions to mathematics, geometry, music, and philosophy.

Pythagoras is most famous for the theorem that bears his name, the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This theorem is fundamental to the study of geometry and has applications in many fields, from architecture to physics.

Answer:

Option (D)

Step-by-step explanation:

In a function y shows the values of the function (Output values) and x shows the (input values).

Therefore, to convert any equation into the function, we will solve the equation for y.

Given equation is,

680x + 10y - 1000 = 0

680x + 10y = 1000

68x + y = 100

y = -68x + 100

Now replace y by f(x).

Therefore, the function will be,

f(x) = -68x + 100

Option (C) will be the correct option.
