A plane is flying at an altitude of 6 km directly over the line AB. It spots two boats, A and B, on the sea.
If the angles of depression of A and B from the plane are 60° and 30° respectively, calculate the
horizontal distance between A and B.
B
6 km
6km
Step-by-step explanation:
altitude here is represent by height ok in this case...
if u look at the diagram that i draw ok from the question we shoul know that we need to use tan... tan is opposite over adjacent...
and the information from the question just sun it into the tan formula...this is trigo...
then u add the value to get the total distance..
the answer is 13.87km
hope u understand...

A piece of fabric 78.25cm long was cut from a 200cm long piece to make a shirt. What percent of the fabric was left behind?
Answer:
39.125 %
Step-by-step explanation:
you use the cross multiplication method:
200cm = 100%
78.25 = ???
78.25 × 100
——————— = 39.125%
200
if you are willing to check your answer:
39.125 × 200
———————–— = 78.25 cm

Answer:
The equation of the lines with the given point does not have a y-intercept of 4 but has a y-intercept of -4.
Step-by-step explanation:
y-intercept is 4
addition ordered pairs on the line are (2, -2), (4, 0), (6, 2), (8, 4)
Find the slope using two of the points: (2, -2), (4, 0).
Slope = (change in the y values)/(change in the x values0
Slope = [0 -(-2)]/ (4 - 2) = 2/ 2 = 1
Checking to see if the y-intercept is 4 substituting slope (m) = 1 and (2, - 2)
y = mx + b
-2 = 1(2) + b
-2 = 2 + b
-2 - 2 = b
-4 = b so we know that the y-intercept is not 4 but it is -4.
Now write the equation of the line using a slope = 1 and y-intercept of -4
y = mx + b
y = x - 4
Next check the other points into the equation of the line to see if the equation is correct.
x = 2 did y = -2 ? y = x - 4; y = 2 - 4 ; y = -2 point (2, -2) works.
x = 4 did y = 0? y = x - 4; y = 4 - 4; y = 0 point (4,0) works.
x = 6 did y = 2? y = x - 4; y = 6 - 4; y = 2 point (6, 2) works.
x = 8 did y = 4? y = x - 4; y = 8 - 4; y = 4 point (8, 4) works.

5/12 divided by 3 in fractions
Answer:
5/36
Step-by-step explanation:
First you need to find the "reciprocal" (the opposite, so the numbers switched around) of the second number, which is 3. In turn, the 3 would become 1/3. Then just multiply the two fractions which is 5/12 x 1/3 = 5/36.
Answer:
5/12 ÷3
Reciprocate
5/12× 1/3
=5/36

2x+y=-4;5x+3y=-6
Answer:
x = -6
y = 8
Step-by-step explanation:
Using substitution method.
2x + y = -4 -----------(I)
y = - 4 - 2x -----------(II)
5x + 3y = -6 -------------------(III)
Substitute y = -4 -2x in equation (III)
5x + 3(-4-2x) = - 6
5x - 12 - 6x = -6
5x - 6x - 12 = -6
Combine like terms
-x - 12 = -6 {Add 12 to both sides}
-x = -6 + 12
-x = 6 {Multiply by (-1)}
x = -6
Substitute x = -6 in equation (II)
y = - 4 - 2*(-6)
= -4 + 12
y = 8

Which of the following equations is steeper?
y=-2x+1
y=-5/4x+7
y=x-1
y=5x-1
Answer:
Option 4: y = 5x - 1
Step-by-step explanation:
The slope, or rate of change, represents the ratio of the vertical change (in y) to the horizontal change (in x) of points along the line. Thus, the slope is a means of measuring the steepness of a given line.
Generally speaking, slopes with higher values tend to have steeper lines.
Compare the slopes:In comparing the slopes of the given options:
Option 1: slope = -2
Option 2: [tex]\LARGE\mathsf{slope = -\frac {5}{4}}[/tex] or 1.25
Option 3: slope = 1
Option 4: slope = 5
Option 4 has the highest slope of 5. Therefore, the graph of y = 5x - 1 has the steepest line.
Attached is the graphed equations to prove that the graph of the equation in Option 4 has the steepest line.

Point B has coordinates (3,2). The x-coordinate of point A is 0 . The distance between point A and point B is 5 units. What are the possible coordinates of point A?
Answer:
A (0, - 2 ) or A (0, 6 )
Step-by-step explanation:
Using the distance formula
d = [tex]\sqrt{(y_{2}-y_{1})^2+(x_{2}-x_{1})^2 }[/tex]
with (x₁, y₁ ) = B(3, 2) and (x₂, y₂ ) = A(0, y )
AB = [tex]\sqrt{(0-3)^2+(y-2)^2}[/tex]
= [tex]\sqrt{(-3)^2+(y-2)^2}[/tex]
= [tex]\sqrt{9+(y-2)^2}[/tex]
Given AB = 5 then equating gives
[tex]\sqrt{9+(y-2)^2}[/tex] = 5 ( square both sides )
9 + (y - 2)² = 25 ( subtract 9 from both sides )
(y - 2)² = 16 ( take square root of both sides )
y - 2 = ± [tex]\sqrt{16}[/tex] = ± 4 ( add 2 to both sides )
y = 2 ± 4
Then y = 2 - 4 = - 2 or y = 2 + 4 = 6
Possible coordinates of point A are
A (0, - 2 ) or A (0, 6 )
Which equation is the inverse of y = x2 +4?

d. y= -x - 4
Anyone know the answer
Answer:
B. [tex]y=\pm\sqrt{x-4}[/tex]
Step-by-step explanation:
Swap the positions of the x and y variables then solve for y again.
[tex]y=x^2+4\\\\x=y^2+4\\\\x-4=y^2+4-4\\\\x-4=y^2\\\\\sqrt{x-4}=\sqrt{y^2}\\\\\pm\sqrt{x-4}=y[/tex]

Given that Sofi stores water for her turtle tank in a container with a maximum capacity of 64 ounces and the container is filled with 4.8 ounces less than its maximum capacity, to determine A) if Sofi accidentally spills 5% of the container's maximum capacity on the counter, to what percent of its capacity is the container now filled, and B) if Sofi needs to add 16 ounces of water to her turtle tank, what percentage of the remaining water in the container does she need to use, the following calculations must be made:
A)
64 = 100 (64 - 4.8) - (64 x 0.05) = X 64 = 100 56 = X 56 x 100/64 = X 87.5 = XTherefore, if Sofi accidentally spills 5% of the container's maximum capacity on the counter, the container is now filled to 87.5% of its capacity.
B)
56 = 100 16 = X 16 x 100/56 = X 28.57 = XTherefore, if Sofi needs to add 16 ounces of water to her turtle tank, she needs to use 28.57% of the remaining water in the container.

Answer:
Step-by-step explanation:
Each boundary line equation is of the form ...
y = mx + b
the value of m is the coefficient of x. The value of b is the constant. You find their values by matching the given relation to the form above, and identifying the matching parts.
y ≤ 1/2x +2 ⇒ m = 1/2, b = 2
y < -2x -3 ⇒ m = -2, b = -3
_____
The slope (m) in each case tells you how many units up (m>0) or down (m<0) the line will go for each unit to the right. The y-intercept (b) in each case gives you a starting point on the y-axis, making it easier to draw the line.
The < part of each inequality symbol tells you the graph will be shaded below the boundary line. (Y-values in the solution set are less than those on the line.) The "or equal to" part of the first inequality symbol tells you the boundary line will be solid. (Y-values on that line are part of the solution set.) The lack of that in the second inequality tells you the boundary line will be dashed.
The graph is shown in the attachment.
