The value of tan A is 5/12.

To find the value of tan A, we use the trigonometric function tangent, which is defined as the ratio of the length of the side opposite angle A to the length of the side adjacent to angle A. In a right triangle, these sides are labeled as x and y, respectively. Therefore, to find the value of tan A, we divide the length of the side opposite angle A (x) by the length of the side adjacent angle A (y).

tan A = x/y

Here,

tan A = 5/12

The scale factor was used to enlarge the picture is 31.5/7 or 4.5.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life

here, we have,

A picture is 7 inches wide and 9 inches long.

A photographer enlarges it so it is 31.5 inches wide and 40.5 inches long.

By simply taking the width after it was enlarged and dividing it by the width before it was enlarged we can find the scale factor that was used.

In this case it would be 31.5 (width after)/ 7 (width before)

which gives us a scale factor of 31.5/7.

Simplifying would yield a scale factor of 4.5 times.

hence, The scale factor was used to enlarge the picture is 31.5/7 or 4.5.

The length of CD is 7 units.

The length along a line or line segment between two points on the line or line segment.

Distance=√(x₂-x₁)²+(y₂-y₁)²

From the figure it is given that C is between A and D.

B is the midpoint of AC

BC=3 and AD=13, we have to find CD.

As B is the midpoint of AC, then BC=AB

BC=AB=3

AC=AB+BC=6

Now to find CD=AD-AC

CD=13-6

CD=7

A group of numbers in a particular order are called a sequence. For instance: a1, a2, a3, a4,..., an,... The first term is designated as a1, the second term as a2, and the nth term as an.

The sequence's first term is a1 = 1, making it the first term. I = 2 and a2 = 2 if I = 2. I = 3, hence a3 = 3 if I = 3.

The definition of an arithmetic sequence's nth term is: The equation a = a1 + (n - 1)d determines the nth term of an arithmetic sequence with a1 as its first term and d as its common difference.

Jamal and Lin will meet 3.21 miles from Jamal's house.

Meet is a gathering of two or more people for a specific purpose, such as to discuss an issue, make a decision, or socialize. It can take place in person or online, either in a formal or informal setting.

The time it takes for Jamal and Lin to meet is the time it takes for Jamal to travel 2 miles plus the time it takes for Lin to travel 2 miles.
Since Jamal is walking at 3 mi/h, it takes him (2 miles) / (3 mi/h) = 0.67 hours to travel 2 miles.
Since Lin is walking at 5 mi/h, it takes her (2 miles) / (5 mi/h) = 0.4 hours to travel 2 miles.
The total time it takes for Jamal and Lin to meet is 0.67 + 0.4 = 1.07 hours.
Jamal and Lin will meet 1.07 hours after they left their houses.
Since Jamal is walking at 3 mi/h, he will have traveled (1.07 hours) * (3 mi/h) = 3.21 miles when they meet.
Jamal and Lin will meet 3.21 miles from Jamal's house.

Answer:

f(5) = 31/11

f'(5) = 4/11

Step-by-step explanation:

y = 4/11x + 1

f(x) = 4x/11 + 1  ==> y = f(x)

f(5) = 4(5)/11 + 1  ==> substitute 5 for x

f(5) = 20/11 + 1  ==> simplify

f(5) = 20/11 + 11/11  ==> make common denominators to simplify easier

f(5) = (20+11)/11

f(5) = 31/11

f'(x) = 4/11

Hence, f'(5) = 4/11 since every value of x will make the derivative 4/11.

Answer:

a³(b-c) + b³(c-a) + c³(a-b) = (a-b)(b-c)(c-a) (a + b + c)(a² + b² + c² - ab - bc - ca)

This is a factorized form of the polynomial, as you can see it factorizes as a combination of difference of squares and difference of cubes.

here is one way to factorize the polynomial a³(b-c) + b³(c-a) + c³(a-b) step by step:

First, we can factor out a³ from the first term, b³ from the second term, and c³ from the third term:

a³(b-c) + b³(c-a) + c³(a-b) = a³(b-c) + b³(c-a) + c³(a-b)

Next, we can factor out (b-c) from the first and second terms, and (c-a) from the second and third terms:

a³(b-c) + b³(c-a) + c³(a-b) = (b-c)(a³ + b³) + (c-a)(b³ + c³)

We can factor out (a-b) from the first and third terms, and then we can use difference of cubes to factorise out:

(b-c)(a³ + b³) + (c-a)(b³ + c³) = (b-c)(a-b)(a² + ab + b²) + (c-a)(a-b)(b² + ab + c²)

Now we can combine like terms, and we get:

(b-c)(a-b)(a² + ab + b²) + (c-a)(a-b)(b² + ab + c²) = (a-b)(b-c)(c-a)(a + b + c)(a² + b² + c² - ab - bc - ca)

The factorized form of the polynomial is (a-b)(b-c)(c-a) (a + b + c)(a² + b² + c² - ab - bc - ca)

This is a general formula for the factorization of a polynomial of the form a³(b-c) + b³(c-a) + c³(a-b)

By using difference of cubes we can factorise the above polynomial, hope it helps.

The height that represents the 85th percentile is 66.8 inches.

The height that represents the first quartile is 62.4 inches.

Generally, To find the height that represents the 85th percentile, you would need to use a z-score table or calculator.

The z-score represents the number of standard deviations away from the mean of a particular value.

For the 85th percentile, the z-score would be 1.04. To find the height, you would use the formula:

(z-score) * (standard deviation) + mean

So, in this case:

1.04 * 2.8 + 63.7 = 66.612 inches

b) To find the height that represents the first quartile (25th percentile), you would use the same process but with a z-score of -0.67.

-0.67 * 2.8 + 63.7 = 61.824

This means that the height that represents the first quartile is 62.4 inches.

Step-by-step explanation:

Firstly you have to open brackets

4b(5a - 2) = 2c

20ab - 8b = 2c

20ab = 2c + 8b

Divide both sides by 20b(coefficient of a)

a = (2c + 8b)/20b

Answer:

[tex]a = \dfrac{2}{5} + \dfrac{c}{10b}[/tex]

Step-by-step explanation:

Expand 4b(5a-2) on the left side

4b(5a-2)  = 4b · 5a -4b · (-2)

= 20ab -8b

Therefore we get

20ab -8b = 2c

Add 8b on both sides to get rid of the -8b on the left

20ab - 8b + 8b = 2c + 8b

20ab = 8b + 2c

Divide by 20 both sides:
20ab/20 = 8b/20 + 2c/20

ab = (2/5)b + c/10

Divide by b both sides

==> ab/b = (2/5)b/b + c/10b

==> a = 2/5 + c/10b

62.5% fo boys plays cricket in the whole class.

A mathematical comparison of two or more values or quantities is called a ratio. It can be used to compare the relative sizes or amounts of various items since it expresses the relationship between the values in terms of a proportion or a fraction.

Let the number of boys who play cricket be x

and  the number of boys who play football be y

so total number of students is x+y

given the ratio that y/x=3/5

so y = 3k and x = 5k where k is a constant

so total number of student is x+y

=> 3k+5k

=> 8k

so percentage of boy who play cricket is given by

The radius of the tank is 28.3 feet (rounded to one decimal place).

Radius is a term used to describe the distance from the center of a circle to any point on the circumference. It is a line segment that runs from the center of the circle outwards, perpendicular to the circumference. The radius of a circle is the same for all points on the circumference, and it is always half of the diameter.

The radius of the tank can be determined using the Pythagorean Theorem. Since we are given the distances from the center of the tank (O) to points A and B, we can use the following formula to calculate the radius:

R = √(OA² + OB²).

Plugging in the given values, we get:

R = √(21² + 19²) = √(441 + 361) = √802 = 28.29

The solution set for the system of equations is (x, y) = (-2.44, 10.11)

To find the solution set for the system of equations, we can use several methods such as substitution, elimination, or matrix method.

In the elimination method, we try to eliminate one of the variables by adding or subtracting the equations.

One method is to use elimination method:

9x + 5y = 28

5x + 9y = 56

We can eliminate one of the variables by multiplying the first equation by -5 and the second equation by 9:

-45x - 25y = -140

45x + 81y = 504

Adding these two equations together we get:

36y = 364

Solving for y, we get:

y = 364/36 = 10.11

We can then substitute this value back into one of the original equations, for example, the first equation:

9x + 5(10) = 28

9x + 50 = 28

9x = -22

x = -2.44

So, the solution set for the system of equations is (x, y) = (-2.44, 10.11)
