The value of the angle tan(D) will be 53.13°.

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that the sides of the triangle are BC = 32 and CD = 24.

The value of tan(D) is calculated as,

tan(D) = 32 / 24

D = tan⁻¹ (32 / 24 )

D = 53.13°

The value of angle D will be 53.13°.

Answer:

In order to form a triangle, the sum of the length of two sides should be greater than the length of the third side. This is called the triangle inequality theorem.

Given the side lengths of 17 cm, 7 cm, and 8 cm, we can see that 17 cm is the longest side. To form a triangle, the sum of the other two sides (7 cm and 8 cm) should be greater than 17 cm.

7 cm + 8 cm = 15 cm which is less than 17 cm. Therefore, it is not possible to construct a triangle with sides 17 cm, 7 cm, and 8 cm.

Step-by-step explanation:

Answer:

No u cannot

Step-by-step explanation:

7+8 = 15 which is less than 17 meaning u cannot create a triangle with this

The statement true about the system of inequalities solution is option A, all the values of satisfy y ≤ 1/3x -1.

One or more linear inequalities in each of the same two variables make up a system of linear inequalities in two variables. A linear inequality's solution is an ordered pair that resolves all of the system's inequalities, and the inequality's graph is a representation of all of the system's solutions.

Given the graph of the system of inequalities we can see that the inequality y ≤ 1/3x -1, comprises of all the values under the blue shaded region. This region also includes the graph of the second inequality.

Hence, option A is correct as all the values of satisfy y ≤ 1/3x -1.

The equation for the parabola given is y=(x-2)^2+1.

What is parabola?

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.

In general, if the directrix is parallel to the y-axis in the standard equation of a parabola is given as:

y^2 = 4ax

If the parabola is sideways i.e., the directrix is parallel to x-axis, the standard equation of a parabola becomes,

x^2 = 4ay

Apart from these two, the equation of a parabola can also be y2 = -4ax and x2 = -4ay if the parabola is in the negative quadrants.

Now, To find the correct equation from the graph

The range of a function  is the set of all the y-values that you get when you plug all of the possible x-values into the function. It is also called a co-domain of function.

To find the range of function write down the function as y=f(x). Find all the minimum to a maximum value of y that satisfies f(x). The values obtained are the range of function. Plot the range on the graph.

For example, if you want to find the range of f(x) = 3x^2 + 6x -2. The lowest y-coordinate is at the vertex, -5, and the values for set y expand infinitely above this point. This means that the range of the function is y={-5, R}

The formula for the area of a triangle is 1/2bh. This formula can be derived from the area of a parallelogram.

A parallelogram is a four-sided shape with two pairs of parallel sides. To find the area of a parallelogram, you need to multiply the base, b, by the height, h. This will give you the area of the parallelogram, which is bh. To find the area of a triangle, you need to divide the area of a parallelogram by two since a triangle has only one set of parallel sides. Therefore, the formula for the area of a triangle is 1/2bh. To calculate the area of a triangle, you need to multiply the base by the height and then divide the result by two. For example, if the base of a triangle is 8 cm and the height is 4 cm, the area of the triangle is 1/2 × 8 × 4 = 16 cm2.

When 5/9 of the tank is filled in 2 minutes, then it will take 3.6 minutes to fill the entire tank.

The definition of a fraction is a fraction multiplied by another fraction, integer, or a group of variables. Given that the 5/9 tank fills in 2 minutes. The duration of this period in seconds is 60×5= 120 seconds.

So the time taken to fill a 1/9 tank is calculated as follows,

Time taken = 120/5

=24 seconds

The time taken to fill the 9/9 tank (full) is calculated by multiplying 24 seconds and 9, we get,

24×9 = 216 seconds

= 3.6 minutes.

Therefore, the required answer is 3.6 minutes.

The change of base formula states that for any logarithm base b and any positive number x: log_b(x) = (log_c(x)) / (log_c(b)), where c is any base.

The change of base formula is a mathematical formula that allows you to convert a logarithm with one base to a logarithm with another base. The formula states that for any logarithm base b and any positive number x: log_b(x) = (log_c(x)) / (log_c(b)), where c is any base.

One way to prove this is to use the properties of logarithms:

Using these properties, we can write log_b(x) as:

log_b(x) = log_b([tex]c^{(log_c(x))}[/tex])

log_b(x) = log_b([tex]c^{(log_c(x))}[/tex]) / log_b(c¹)

log_b(x) = log_c(x) / log_c(b)

A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

The slope-intercept form of the equation of a line is y = mx + c, where

The slope of a line perpendicular to another line is the negative reciprocal of the original line's slope. In this case, the original line has a slope of 34, so the slope of the line that is perpendicular to it is -1/34.

To find the y-intercept of the line, we can use the point (0,3) that the line passes through. Substituting the x and y values of this point into the equation of the line, we get 3 = -34(0) + c, which simplifies to c = 3.
