We have to graph the equation 4y=5x+20 using the intercepts.
First we are going to find the y-intercept of the line, to do this we have to remember that the line intercepts the y-axis when x=0. Plugging this value of x in the equation we have
[tex]\begin{gathered} 4y=5(0)+20 \\ 4y=20 \\ y=\frac{20}{4} \\ y=5 \end{gathered}[/tex]Hence the y-intercept is 5. This represents the point (0,5).
Now we draw this point on the graph:
Now we have to find the x-intercept of the line, this happens when y=0. Plugging this value of y in the equation we have that
[tex]\begin{gathered} 4(0)=5x+20 \\ 0=5x+20 \\ 5x=-20 \\ x=-\frac{20}{5} \\ x=-4 \end{gathered}[/tex]Then, the x-intercept is -4. This represents the point (-4,0).
Drawing this point on the graph we have.
Now we only connect the points with a straight line:
That's the graph of the line that we find with the intercepts.

The expression is √3/2 (sin x) - (cos x)/2
Here we have
sin( x + 11π/6)
We have to express it in terms of sin(x) and cos(x)
sin ( 2π - π/6 + x)
sin ( 2π + ( x - π/6))
sin(2π + Ф ) = sin Ф
So
sin( x - π/ 6)
Formula :
sin(A -B) = sin A cos B - cos A sin B
sin( x - π/ 6)
sin x cos π/6 - cos x sin π/6
con π/6 = √3/2 and sin π/6 = 1/2
√3/2 sin x - 1/2 cos x
Therefore the expression is √3/2 sin x - 1/2 cos x.

A boat heading out to sea starts out at Point AA, at a horizontal distance of 1035 feet from a lighthouse/the shore. From that point, the boat’s crew measures the angle of elevation to the lighthouse’s beacon-light from that point to be 8^{\circ} ∘ . At some later time, the crew measures the angle of elevation from point BB to be 5^{\circ} ∘ . Find the distance from point AA to point BB. Round your answer to the nearest foot if necessary.
Answers
The angle of elevation reduces. The distance between points A and B is roughly 1,269.9 ft.
The distance between point A and the lighthouse is 968 feet.
The angle of elevation from point A to the lighthouse is 7 degrees.
Elevation angle from point B to the lighthouse = 3°
The distance between points A and B.
tan 7° = Height of the sea / 968 feet
tan(7°) 968 feet 118.86 feet = height to the lighthouse
We have from point B;
tan 3° = 118.86 / Horizontal distance from B to HL
Therefore;
Horizontal distance from LH to boat = 118.6 / tan 30° = 2237.9 = feet
Therefore;
D is the distance between A and B.
D = Horizontal distance between B and LH - Horizontal distance between A and LH
A to B distance = 2237.9 feet − 968 feet 1269.9 feet
The distance between points A and B is 1,269.9 ft.

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
The first step must be to convert days to hours. A day is equivalent to the 24 hours.
1 day = 24 hours
24 x 7 = 168 hours
The second step must be to convert minutes to hours,
60 minutes = 1 hour
15 / 60 = 0.25 hours
Now, add up all the converted hours together;
Total hours = 168 hours + 3 hours + 0.25 hours

A packing carton has a square bottom 18 inches by 18 inches. If the capacity of the carton is 3cubic feet, how deep is the carton?
Answers
The packing carton has a square bottom with measures 18in x 18in and has a volume of V=3ft³
The volume of cubic prims can be calculated by multiplying its width by its length and height:
So the formula to calculate the volume is
[tex]V=w\cdot l\cdot h[/tex]If we know the width, length, and volume we can determine the height. First, write the formula for h, that is, divide the volume by the width and height:
[tex]h=\frac{V}{wl}[/tex]The units of the width and length are in inches and the volume is in cubic feet, to determine the height of the box, all units must be the same. To make the calculations easier I will pass the units from inches to feet.
The unit rate between inches and feet is the following:
[tex]1^{\doubleprime}=\frac{1}{12}ft[/tex]To express 18 inches in feet you have to multiply them by 1/12
[tex]18\cdot\frac{1}{12}=1.5[/tex]This means that the width and length of the box measure 1.5ft
Now we can determine the height of the box as follows:
w=l=1.5ft
V=3ft³
[tex]\begin{gathered} h=\frac{V}{wl} \\ h=\frac{3}{1.5\cdot1.5} \\ h=\frac{4}{3}ft \end{gathered}[/tex]The height of the box is 3/4ft, if you multiply it by 12 you can express the measure in inches:
[tex]\frac{3}{4}\cdot12=9[/tex]The box has a deph of 9 inches.

Answer:
y = x-13
Step-by-step explanation:
So this question asks for two numbers. Let's call them x and y.
Since we know that x is larger than y, and the difference between them is 13, x must be greater than y by 13. So, x = y + 13
x = y + 13 isn't what the question is asking for though, so we have to isolate y to make one side contain only x and numbers. To do that, subtract both sides by 13 to get:
x - 13 = y
rearrange:
y = x - 13

Find the area and perimeter of a rhombus with a diagonals 15 in and 20 in

Given data:

The diagonal of the rhombus is considered as diameter, so the radius will be
