if sin=3/5 then what does tan equal

Answer:

x =  2.5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the gradient and c the y- intercept )

here m = - 2 and c = 5, so

y = - 2x + 5 ← equation of line

To find the x- intercept let y = 0, that is

- 2x + 5 = 0 ( subtract 5 from both sides )

- 2x = - 5 ( divide both sides by - 2 )

x =  2.5 ← x- intercept ⇒ (2.5, 0 )

Answer:

The answer is 8.

Step-by-step explanation:

Go from left to right.

2x2x2

Take the first two numbers: 2 x 2; this equals 4.

Take that number and multiply by the next number (2): 4 x 2 = 8

Hope this helps! :)

The value of 2 x 2 x 2 using the multiplication operation gives the result 8.

The expression 2 x 2 x 2 represents the multiplication of three 2's together.

To simplify the expression, perform the multiplication operation:

= 2 x 2 x 2

= 4 x 2

= 8

Therefore, 2 x 2 x 2 is equal to 8.

In other words, multiplying three 2's together results in the value of 8.

This can be visualized as multiplying 2 by 2 to get 4 and then multiplying that result by 2 again to obtain 8.

Option: B is the correct answer.

The function is:

Answer:

Rational

Step-by-step explanation:

1.256 is not a whole #, and it's also not an integer. An integer is basically whole #s and their opposites. The # is not irrational. 1.256 is a terminating decimal, and can be turned into a fraction. 1.256 = 1 32/125.

The number 1.256 is a rational number because it can be expressed as a ratio of two integers (1256/1000). It is not a whole number or an integer due to its decimal component.

The question is whether the number 1.256 belongs to the sets of rational numbers, whole numbers, or integers. Contrary to the student's initial thought, 1.256 is not an irrational number. Instead, it is a rational number because it can be expressed as a ratio of two integers.

Specifically, 1.256 can be written as 1256/1000, where both the numerator and denominator are integers. Therefore, this number belongs to the set of rational numbers. It is not a whole number or an integer, as both of these sets require numbers without fractional or decimal components.

Answer:

Part 1) The volume of each beam is [tex]1,858.88\ ft^{3}[/tex]

Part 2) You can fill [tex]26\ beams[/tex]

Part 3) Yes, the amount of sand left over is [tex]1,669.12\ ft^{3}[/tex]

Step-by-step explanation:

Part 1) What is the total volume of each beam?

The volume of a cylinder is equal to

[tex]V=\pi r^{2} h[/tex]

we have

[tex]h=37\ ft[/tex]

[tex]r=8/2=4\ ft[/tex] ----> the radius is half the diameter

assume

[tex]\pi=3.14[/tex]

substitute the values

[tex]V=(3.14)(4)^{2} (37)[/tex]

[tex]V=1,858.88\ ft^{3}[/tex]

Part 2) How many beams can you fill with this sand?

we know that

You are given a container with a 50,000 sq ft of sand for your beams

Note Is a 50,000 cubic foot  of sand instead of 50,000 sq ft of sand

Divide the total volume of sand by the volume of each beam to obtain the number of beams

[tex]50,000/1,858.88=26.9\ beams[/tex]

Round down

[tex]26.9=26\ beams[/tex]

Part 3) Will you have any sand left over? If so how much?

yes

[tex]50,000-26(1,858.88)=1,669.12\ ft^{3}[/tex]

Answer:

That is correct.

Step-by-step explanation:

5 times 0.1=0.5

8 times 0.01=0.08

20+4+0.5+0.08=24.58

That is correct.

Oh now I see. Yes that is correct

So this is what I got before, in the other question you asked, and the expanded form on the paper is the same thing as this. The way I wrote it is just another version, both are correct:

20.00 + 4.00 + 00.50 + 00.08

(2 x 10) + (4 x 1) + (5 x 0.1) + (8 x 0.01)

Multiply all the numbers together in each parentheses set and you'll get the same thing as the other problem I answered!

In the first set of parentheses (2 x 10) when solved is equal to 20

20.00 + 4.00 + 00.50 + 00.08

In the second set of parentheses (4 x 1) when solved is equal to 4

20.00 + 4.00 + 00.50 + 00.08

In the third set of parentheses (5 x 0.1) when solved is equal to .5

20.00 + 4.00 + 00.50 + 00.08

In the fourth set of parentheses (8 x 0.01) when solved is equal to 00.08

20.00 + 4.00 + 00.50 + 00.08

Hope this was way more helpful!

The explicit rule for the given sequence is to add 3.5 to each previous term.

The given sequence is:

10.5, 14, 17.5, 21, 24.5, ...

The explicit rule for this sequence is that each term is obtained by adding 3.5 to the previous term. So, the nth term of the sequence can be represented by the formula:

Tn = Tn-1 + 3.5

where Tn is the nth term of the sequence and Tn-1 is the previous term.

Final answer:

The explicit rule for the sequence 10.5, 14, 17.5, 21, 24.5, ... is a_n = 7 + 3.5n.

Explanation:

The sequence given is 10.5, 14, 17.5, 21, 24.5, ... and we need to find an explicit rule for this sequence in simplified form. Observing the sequence, we see that each term is increasing by 3.5. Therefore, the common difference in this arithmetic sequence is 3.5. We can express the nth term of the sequence using the formula:

an = a1 + (n - 1)d, where a1 is the first term and d is the common difference.

Since the first term a1 is 10.5 and d is 3.5, the rule for the nth term is:

which simplifies to an = 7 + 3.5n.

We multiply the second equation by 2:

[tex]3x-2y = 14\\10x + 2y = 64[/tex]

We add the equations:

[tex]13x = 78\\x = \frac {78} {13}\\x = 6[/tex]

We substitute the value of "x" in the following equation, and we clear the value of "y":

[tex]5 (6) + y = 32\\30 + y = 32\\y = 32-30\\y = 2[/tex]

Answer:

15. h⁻¹ (x) = 5x-6/2

16. (g.f)x = 4x^2 -2x -1

Step-by-step explanation:

15. Find Inverse of h(x) =  2x+6 /5

Let y = 2x+6/5 we need to find value of x

Multiplying both sides with 5

5y = 2x+6

Adding -6 on both sides

5y -6 = 2x

Dividing both sides by 2

5y-6/2 = x

Now replace y with x our answer will be:

h⁻¹ (x) = 5x-6/2

16. f(x) =2x-1 and g(x) = x^2 -2 find (g.f)x

(g.f)x can be written as: g(f(x))

We know f(x) = 2x-1 so, put value of f(x) into x of g(x).

Putting values we get:

(g.f)x = g(f(x))= (2x-1)^2 -2

                   = 4x^2 -2x +1 -2

                   = 4x^2 -2x -1

so, (g.f)x = 4x^2 -2x -1

Answer:

6 x + 12

Step-by-step explanation:

Hexagon = 6 sides

1 side = x + 2

( Multiply by 6 to get 6 sides )

6 sides = 6 x + 12

The perimeter of a regular hexagon with a side length of x + 2 would be 6x + 12. This is achieved by multiplying the length of one side (x + 2) by 6 (total sides in a hexagon).

The perimeter of any regular shape is given by the sum of its sides. In a regular hexagon, all sides are equal. Therefore, if one side is x + 2, then the perimeter would be six times that side length. This is because a hexagon has six sides. So, if we multiply the length of one side (x + 2) by 6 the result will be the total perimeter. Hence, the perimeter of the regular hexagon would be 6(x + 2), which simplifies to 6x + 12.

Answer:

Volume=2.2*10^10  km^3

Step-by-step explanation:

Given

Diameter of moon=d=3476 km

The formula for the volume of sphere is:

V=4/3 πr^3

As it can be clearly seen that the formula uses radius, and we are given diameter. So we have to find the radius first

So,

radius=r=d/2

=3476/2

=1738 km

Now putting the value of r and pi in the formula:

V=4/3*3.14*(1738)^3

=12.56/3* 5249879272

= 21979494552.106

Rounded off to two significant digits:

Volume=2.2*10^10  km^3

Answer:

[tex]V=2.2\ x\ 10^{10} km^3[/tex]

Step-by-step explanation:

The formula to calculate the volume of a sphere is:

[tex]V=\frac{4}{3}\pi r^3[/tex]

Where r is the radius of the sphere.

In this case we do not know the radius of the sphere, but we know the diameter.

By definition the diameter of a sphere is equal to twice the radius. This is:

[tex]d = 2r[/tex]

[tex]r = \frac{d}{2}[/tex]

In this case d= 3,476 km

So

[tex]r = \frac{3,476}{2}[/tex]

[tex]r = 1738\ km[/tex]

Finally

[tex]V=\frac{4}{3}\pi (1738)^3[/tex]

[tex]V=2.20\ x\ 10^{10} km^3[/tex]

Final answer:

Discrimination, particularly in the labor market as demonstrated by disparities in job callbacks and opportunities based on race, gender, and disability, represents a systemic issue that persists despite legal protections against such practices.

Explanation:

Discrimination is the unfair treatment of individuals or groups based on characteristics such as race, gender, or religion. One of the most common forms of discrimination occurs in the labor market, where individuals may face disparities in job opportunities and wages. An example of this is how studies have shown that individuals with white sounding names receive more callbacks for interviews than African-American names, indicating racial discrimination. Furthermore, women and those disclosing a disability also face significant hurdles in the job market, highlighting gender discrimination and disability discrimination. Despite the existence of laws against discrimination in the United States and global conventions from the United Nations aimed at eliminating all forms of discrimination, these practices unfortunately persist. Institutional discrimination extends beyond individual acts of prejudice to include systemic issues such as white privilege, which confers benefits upon the dominant group often without their conscious acknowledgment.
