Please help fast!!!

Answers

Answer:

Option D

Step-by-step explanation:

We have that:

csc(x) = 1/sin(x)

Then:

csc(  tan(√(17)/8)^-1 )

To use the inverse tangent function, you can go to the "inv" button in your calculator, and then use go to the "tan" button.

This is equal to:

= csc( 27.26°)

= csc(27.26°)

= 1/sin(27.26°) = 2.18

And we know that:

(9*√17)/17 = 9/√17 = 2.18

Then the correct option is D.

[tex]\boxed {\boxed {\sf (4,3) \ is \ not \ a \ solution}}[/tex]

Step-by-step explanation:

If we want to test a solution, we can plug it into the equations and see if it checks out.

We are given the point (4,3). Since points are written (x,y)...

x=4 y=3

Substitute the values into the first equation.

[tex]11x+9y=17 \\11(4)+9(3)=17[/tex]

Multiply.

[tex]44+ 27=17\\[/tex]

Add.

[tex]71 \neq 71[/tex]

This does not check out, so we automatically know this point doesn't work. However, we can check the other equation.

[tex]x+y=7 \\4+3=7\\7=7[/tex]

Even though the second equation works, BOTH have to work because this is a system of equations. Therefore, (4,3) is not a solution.

to find y, flip the equation: 180 - 25 = 155. Therefore y = 155 :)

Remark

I take it you are studying the sine law. If that is so, Then it will be set up as

Formula

x/sin(53) = 7 / sin(44)     Multiply both sides by Sin(53)

Solution

Sin(53)x/Sin(53) = 7 sin(53)/Sin(44)

x = 7*Sin(53)/Sin(44)

x = 7 * 0.7986/0.6947

x = 8.0848

Note:

The sine law is always set up by 2 ratios. It consists of the sine of an angle divided by the side opposite = equal to another angle's sine over the side oppose the second angle.

The sine law can also be set up as two ratios side opposite / sin(Angle).

Answers

Answer:

The area of the triangular section is 12 square units. The area of the entire figure is  60  square units.

Step-by-step explanation:

The area of the triangular section is 12 square units and the area of the entire figure is 60 square units

How to determine the area?

The dimension of the triangular section is:

Base = 12 - 6 = 6 units

Height = 4 units

So, the area is:

Area = 0.5 * Base * Height

This gives

Area = 0.5 * 6* 4

Area = 12 square units

The area of the entire figure is then calculated as;

Area = Triangle + Rectangle

This gives

Area = 12 + 12 * 4

Evaluate

Area = 60

Hence, the area of the triangular section is 12 square units and the area of the entire figure is 60 square units

A web store offers two versions of a popular song. The size of a standard version is 2.9 MB. The size of the high-quality version is 4.4 MB. Yesterday, there were 910 downloads of the song, for a total download size of 3014 MB. How many downloads of the standard version were there

Answers

Answer:

This problem is a great systems of equations problem--you have two different variables: song size and number of songs.

Let's call the number of standard version downloads (S) and the high quality downloads (H).

You can make two statements:

For number of songs downloaded: S + H = 910

For download size: 2.8(S) + 4.4(H) = 3044.

S will be the same number in both equations and H will be the same number in both equations, so to find S, we can rearrange the first statement to H = 910 - S, then substitute or plug in (910 - S) wherever you see an H in the second equation so that you have only S's in your equation. Should look like this:

2.8(S) + 4.4(910 - S) = 3044

2.8S + 4004 - 4.4S = 3044

-1.6S = -960

s = 600

Your question only asks for the standard version downloads, but to help you out in future Systems situations-

You can also solve for H once you have S by plugging it into either of your equations like this:

600 + H = 910

-600

H=310

Step-by-step explanation:

given the following

f(x) = 5x² + 2

g(x) = x²-1

g(f(x)) = g(5x²+2)

Replace x with 5x² + 2 in g(x) as shown;

g(5x²+2) = (5x²+2))²- 1

g(f(x)) = (5x²+2))²- 1

g(f(-1)) = (5(-1)²+2))²- 1

g(f(-1)) = (5+2))²- 1

g(f(-1)) = (7)²- 1

g(f(-1)) = 49 - 1

Line 1 => slope is horizontal. The slope of horizontal lines are always equal to 0. Therefore, the slope of line 1 is zero.

Line 2 => the line slants downwards form our left to the right, this implies there is a decline or increase. Thus, the slope would be negative.

Line 3 => the line of a vertical line is always undefined. Line 3 slope is therefore undefined.

Line 4 => the slope slants upwards from our left to the right. This indicates a rising slope or an increase. Therefore, the slope of line 4 is positive.
