Step-by-step explanation:

[tex]tan(30) = (\frac{x}{7} )\\x = 7*tan(30)[/tex]

After this step, find the button on your calculator that says 'tan' and type n 30 degrees, then press enter or the equal sign or whatever button you press to calculate.

You should get that tan(30) = 0.5774

Now plug that back into the equation

     [tex]x = 7 * 0.5774 = 4.0415[/tex] (approximated)

Hope that helps!

Step-by-step explanation:

rewrite the equation as x/7 = tan (30).

x/7= tan (30)

multiply both sides of the equation by 7 .

7•x/7=7• tan (30)

simplify both sides of equation x=7π3/3

the result can be shown in multiple forms exact forms x=7π3/3

decimal form x=404145188...

TAN (30) =X/7

Answer:

y = 500(1.10)^4

Step-by-step explanation:

We put the 1 in 1.10 instead of 0.10, because we're trying to find 10% of $500, added to the $500 itself. 1 is the same as 100%. 100% here is $500. So by doing 1.10, we're finding 110% or $500 + 10% of $500.

Hope this makes sense :))

I assume you're just solving for x. Factorize the left side as

3 sin²(x) - 3 sin⁴(x) = 3 sin²(x) (1 - sin²(x)) = 0

Recall that

sin²(x) + cos²(x) = 1

so that the equation further reduces to

3 sin²(x) cos²(x) = 0

Also recall the double angle identity,

sin(2x) = 2 sin(x) cos(x)

which lets us rewrite the equation as

3/2² (2 sin(x) cos(x))² = 3/4 sin²(2x) = 0

Solve for x :

3/4 sin²(2x) = 0

sin²(2x) = 0

sin(2x) = 0

2x = arcsin(0) + 2nπ   or   2x = π - arcsin(0) + 2nπ

(where n is any integer)

2x = 2nπ   or   2x = (2n + 1) π

x = nπ   or   x = (2n + 1)/2 π

Notice that this means the solution set is

{…, -2π, -3π/2, -π, -π/2, 0, π/2, π, 3π/2, 3π, …}

so we can condense the solution further to

x = nπ/2

with any integer n.

Answer:

50.24 cm^2

Step-by-step explanation:

r=4, so the answer is 16π. replacing π with 3.14 to get 50.24 cm^2

Answer:

cos F is 15/28

Step-by-step explanation:

Use SOH CAH TOA

CAH is for cosine and it's Adjacent over Hypotenuse

the adjacent side of F is 15 and the hypotenuse is 28

So 15/28 which does not simplify

Distribute the 34 to both the x and -1, and once you do that, your answer is 34x - 34

The condition that calls be made between 8am and 4pm will exclude anyone who leaves home for work or school during those hours, which are the most common work periods of the day.  The sampling will consist primarily of home-keepers, babysitters, or students skipping class or doing homework, with an occasional worker who works the night shift and is upset with the call since it woke that person from sleep.

Answer: I am not sure exactly what you need as there is no context

-> See attached for graph

-> They intersect at point (2, -1)

Step-by-step explanation:

     To answer your question of "I mainly need help with knowing what to do with y=-1​" you will graph it as you do with y = - [tex]\frac{5}{2}[/tex]x + 4.

     Any y = something equation will be a horizontal line. There is no slope, the "mx" chunk, so the line stays straight. You will put a dot at (0, -1) and draw a line straight from that point.

     For y = - [tex]\frac{5}{2}[/tex]x + 4, place a dot at (0, 4) and then count down 5 units and 2 units to the right to place another dot. Then draw a line through these two dots and extend it beyond to create the line.

y=-1 is nothing but it's the y value by using that we have to find the x value

Answer:

2; 3; 10

Step-by-step explanation:

1.) There are 4 halves (1/2) in 2; 4/2 = 2

2.) There are 15 1 fifths (1/5) in 3; 15/5 = 3

3.) There are 10 1 eights (1/8) in 1 and 1 fourth; 1.25/0.125 = 10

Assuming that this is a parallelogram, that means the angle opposite each other like Angle L to Angle J and Angle K to Angle M are equal in angle measure.

Thus Angle L is 98 degrees like Angle J

Step-by-step explanation:

Domain tells us all the possible x values or inputs of a function.

Here the input is n.

The domain here is defined on the interval [-1,3) so the domain can be notated in 3 ways.

Interval Notation: [-1,3]

Words: All inputs that is between -1 and 3, exclusively.

Sign Notation:

[tex] - 1 \leqslant x \leqslant 3[/tex]

The Range of a function is possible y values or outputs of a function.

For the range, plug in x values to find the y values.

Since the range in this problem, is only defined for -1 to 3. Plug in -1 for n in the function.

[tex]2( - 1) - 1 = - 3[/tex]

[tex]2(3) - 1 = 5[/tex]

So the range of is

[-3,5]

Or could be stated

All outputs between -3 and 5 exclusively

[tex] - 3 \leqslant x \leqslant 5[/tex]

Geometry has influenced how civilizations have constructed buildings and stadiums. In Ancient Greece, the “golden rectangle” was used to build aesthetically pleasing buildings that look to be in perfect proportion. It helps in the accurate calculation of the physical distances. It is employed in the field of astronomy to map the distances between stars & planets and between different planets. It also aids in the determination of a relationship between the movements of different bodies in the celestial environment.

For WXYZ to be a parallelogram, the value of x must be 3.

A parallelogram is a quadrilateral in which opposite sides are parallel and equal to each other. Opposite angles are also equal to each other. In a parallelogram, diagonals bisect each other when they intersect each other.

In a parallelogram when diagonals intersect, they bisect each other.

So, WC and CY will be equal to each other

i.e. WC = CY

i.e. [tex]2x+5 = 3x+2[/tex]

Answer:

The area of a triangle can be determined with the two side lengths, the length and breadth/width multiplied.

x = unknown value of breadth/width

23 = length

506 = the area of the two lengths multiplied

23(x) = 506

/23        /23

x = 22, 22 metres is it's breadth.

Answer:

22m is the breadth of the rectangle.
