A plane (at point P) sees a bridge (at point B) at an angle of depression on 28 degrees. The horizontal distance between the plane and the bridge is 3000 feet. Explain which trigonometric equation can be used to solve for the height of the plane (segment PA). What is the height of the plane? You must show all work and calculations to receive full credit. Round your answer to the nearest foot.
Answers
The height of the plane PA is given as; 1591 ft
How to use trigonometric ratios?
There are different trigonometric ratios such as;
cos θ = adjacent/hypotenuse
sin θ = opposite/hypotenuse
tan θ = opposite/adjacent
Now, looking at the given image showing plane and bridge indicated by lines, we can use one of the trigonometric ratios to get the height of the plane PA as;
PA/3000 = tan B
now angle B = 28 degrees from alternate angles postulate. Thus;
PA/3000 = tan 28
PA = 3000 * tan 28
PA = 3000 * 0.5317
PA = 1591 ft

I’m stuck on what equation I need to set up
Answers
The painting is a square, which means all its sides are equal.
If x is the length of one side, then, all the remaining 3 sides also have the same length: x.
The area of a square is the square if its side, then, for a square with sides x:
[tex]\text{Area}=x\cdot x=x^2[/tex]We know that the area of the painting will be 400 square inches, then:
a. The equation that can be set up to find the length of a side is:
[tex]x^2=400in^2[/tex]b. We can solve the equation by finding a number that multiplied by itself gives 400. For this case, we have two solutions. 20 and -20, since:
[tex]20^2=20\cdot20=400[/tex]And:
[tex](-20)^2=(-20)\cdot(-20)=400[/tex]-20 is also a solution because as a negative number, when multiplied by itself, gives a positive one. (A product between negative numbers gives always a positive number).
c. We have two solutions, however, only one of them makes sense: the 20. A negative length makes no sense, so we can discard the second solution (-20).
d. The length of the wood trim needed to go around the painting is then 20 inches. (we should not forget the units.)

Slope-intercept form is y = 21.
What is a equation of line?The equation y = mx + c is the general equation of any straight line where m is the gradient of the line (how steep the line is) and c is the y -intercept (the point in which the line crosses the y -axis).
Given that,
The line is horizontal. It means slope of this line is zero. We can use the point-slope form for a linear equation since we know the slope and the point (15, 21).
Point-slope form: [tex](y-y_{1}) = m(x-x_{1})[/tex]
Where,
m = slope and [tex](x_{1}, y_{1})[/tex] is the points.
Then,
[tex](y-y_{1}) = m(x-x_{1})[/tex]
[tex](y-21) = 0(x-15)[/tex]

According to the given problem,
(i) It is given that,
The cost price of 1000 packets of peanuts = Rs. 50
We need to find the cost price of 1 packet of peanut = [tex]\frac{50}{1000}[/tex] = Rs. 0.05
(ii) Selling price at which Sipho continues to sell 1 packet = Rs. 1
Then Selling price of 1000 packets = 1000 x 1 = Rs. 1000
Then Profit made by sipho = Selling Price - Cost Price

Answers
As shown in the reference graph attached hereby with the question statement, if the linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time "x" measured in seconds, then,
(A) During (2 ≤ x ≤ 5) seconds in the time domain, the water balloon's height remains the same.
(B) During (0 ≤ x ≤ 2) seconds, the height of the water balloon is increasing.
(C) During (5 ≤ x ≤ 6) seconds, the height of the water balloon decreases the fastest.
(D) From Part (C), it can be justified that 5 ≤ x ≤ 9.5 is the interval where the balloon's height is decreasing, and, (5 ≤ x ≤ 6) is the interval where the slope is the steepest.
As per the question statement and the reference graph attached alongside, the linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time "x" measured in seconds.
We are required to determine the correct time domains for four different situations, by observing the plotted graph.
Part (A) is to determine the correct time domain where the water balloon's height remains the same.
From the graph, it is clear that, the height remains constant at (y = 70), parallel to the x-axis from the 2nd second to the 5th second. Hence, During (2 ≤ x ≤ 5) seconds in the time domain, the water balloon's height remains the same.
Part (B) is to determine the correct time domain where the height of the water balloon is increasing.
From the graph, it is clear that, the slope of the concerned graph rises only from [(y = 40) to (y = 70)], starring from the 0th second until the 2nd second. Hence, During (0 ≤ x ≤ 2) seconds in the time domain, , the height of the water balloon is increasing.
Part (C) is to determine the correct time domain where the height of the water balloon decreases the fastest.
From the graph, it is clear that, the graph decreases thrice, first from [(y = 70) to (y = 40)], starting at the 5th second uptil the 6th second, then from [(y = 40) to (y = 10)], starting at the 6th second uptil the 9th second and lastly, from [(y = 10) to (y = 0)], starting at the 9th second till the 9.5th second. Here, we can easily calculate that, the balloon dropped 30ft in 1 sec at the first instance, 30ft in 3 seconds at the second instance and, 10ft in 0.5 seconds.
Since, [(30/1) > (10/0.5) > (30/3)],
Or, [30 > 20 > 10],
Thus, During (5 ≤ x ≤ 6) seconds, the height of the water balloon decreases the fastest.
Part (D) is to determine the correct statement mentioned under it's options, with judgement based on Part (C).
Option (i) states that [(5 ≤ x ≤ 9.5) is the interval where the balloon's height is decreasing] which is true, as we can observe from the graph that the slope is decreasing during the time interval of 5 to 9.5th seconds, although at different rates at different intervals.
Option (ii) states that [(8 ≤ x ≤ 9.5) is the interval where the slope is the steepest] which means that, during this above said interval, the height of the balloon drops the fastest which is false, as we have already proved in part (C) that during (5 ≤ x ≤ 6) seconds, the height of the water balloon decreases the fastest.
Option (iii) states that, [(6 ≤ x ≤ 8) is the interval where the balloon's height decreases the most] which is false, as balloons height falls the farthest by 30fts in two separate intervals, between (5 ≤ x ≤ 6) seconds and (6 ≤ x ≤ 9) seconds.
Finally, Option (iv) states that [(5 ≤ x ≤ 6) is the interval where the slope is the steepest] which means that, during this above said interval, the height of the balloon drops the fastest which is true, as we have already proved in part (C) that during (5 ≤ x ≤ 6) seconds, the height of the water balloon decreases the maximum in the shortest time period.

Answers
there are two aircraft carriers, a and b, and carrier a is longer in length than the carrier b. then Carrier A is 2,104 feet and Carrier B is 2,094 feet.
Since there are two aircraft carriers, A and B, and carrier A is longer in length than the carrier B, and the total length of these two carriers is 4198 feet, while the difference of their lengths is only 10 feet, to determine the length of each aircraft carrier, the following calculation must be performed:

2,094 = X
2,094 + 10 = 2,104

What is the m∠QPT? Show work.
Answers
Answer:
m∠QPT = 32°
Step-by-step explanation:
∠QPT and ∠SPR are vertical angles, meaning that the measure of their angles are congruent (the same).
Vertical angles are formed when two lines intersect, creating opposite angles. Those opposites are congruent (equal).
Step 1: Set the measure of the angles to equal each other.
[tex]\implies m \angle QPT = m \angle SPR[/tex]
[tex]\implies (2x+12) = (4x - 8)[/tex]
Step 2: Subtract 4x from both sides.
[tex]\implies 2x-4x+12 = 4x - 4x - 8[/tex]
[tex]\implies -2x+12 = - 8[/tex]
Step 3: Subtract 12 from both sides.
[tex]\implies -2x+12-12 = - 8-12[/tex]
[tex]\implies -2x = -20[/tex]
Step 4: Divide both sides by -2.
[tex]\implies \dfrac{-2x}{-2} = \dfrac{-20}{-2}[/tex]
[tex]\implies x = 10[/tex]
Step 5: Find the measure of ∠QPT by substituting 10 for x.
[tex]\implies [2(10)+12]^{\circ}[/tex]
[tex]\implies 32^{\circ}[/tex]
Therefore, the measure of ∠QPT is 32°.

[tex]y<-\frac{5}{2}x+3[/tex]Which are the values below the dotted line.
Answer:
[tex]y<-\frac{5}{2}x+3[/tex]3) Graph the solution set to y - 2x = -5 on the
coordinate plane.
Answers
Answer:
y=2x-5
Step-by-step explanation:
y - 2x = -5
add 2x to both sides.
y=-5+2x
Answer:
y = 2x - 5 is a line. determine the two points that this line intersects with the axes then connect these points to graph it.
Step-by-step explanation:
Given y = 2x -5 set y = 0 then solve for the abscissa
y = 2x - 5
0 =2x - 5
2x=5
x = 5/2
we now have the point (5/2,0)
set now x = 0 then solve for ordinate
y = 2x - 5
y = 2(0) - 5
y = -5
we now have the point (0, - 5)
we now simply draw a line passing thru the two points ( 5/2, 0) and (0, - 5)
kindly see the graph of y = 2x - 5 with points (5/2, 0) and (0, - 5)

Length of major axis Length of minor axis
Answers
The lengths of the axes in the elipse are given as follows:
Major axes: [tex]8\sqrt{14}[/tex].Minor axes: [tex]4\sqrt{53}[/tex].Equation of an elipseThe equation of an elipse of center (x*, y*) is given according to the following rule:
(x - x*)²/a² + (y - y*)²/b² = 1.
The lengths of the axes are given as follows:
Major axes: 2 x greater of a or b.Minor axes: 2 x lesser of a or b.In this problem, the equation of the elipse is given as follows:
(x - 3)²/212 + (y + 4)²/224 = 1.
Hence the measures of a and b are calculated as follows:
Measure of a: a² = 212 -> a = sqrt(212) -> a = 2sqrt(53).Measure of a: b² = 224 -> b = sqrt(224) -> b = 4sqrt(14).Hence the lengths of the axes have numeric values given by:
Major axes: 2 x 4sqrt(14) = 8sqrt(14) = [tex]8\sqrt{14}[/tex].Minor axes: 2 x 2sqrt(53) = 4sqrt(53) = [tex]4\sqrt{53}[/tex].The difference in the measures is because I suppose there was a typo in the equation of the ellipse, but the procedure is as presented in this problem.

The equation P=3s represents the perimeter P of an equilateral triangle with side length s. is there a proportional relationship between the perimeter and the side length of an equilateral triangle? Explain.
Answers
The constant of proportionality (K ) we will write
Perimeter = 3 ( side) where K = 3
Perimeter of any polygon is defined as the sum of all sides of polygon.
Given polygon is a triangle. A triangle is any polygon which has three sides.
And as the sides of a polygon increases the perimeter also increases.
One can say that perimeter and side of a polygon has a direct relationship.
That is when we write it mathematically we write it like:
Perimeter ( P ) ∝ Sides of polygon
However given is an equilateral triangle
this means that all sides of the triangle are equal
so let us consider the side of the triangle as "s"
Thus we get that perimeter will be 3 times s
which when mathematically written will be:
Perimeter ∝ ( side)
to remove the constant of proportionality (K ) we will write
Perimeter = 3 ( side) where K = 3
