From a plane flying due east at 265 m above sea level, the angles of depression of two ships sailing due east measure 35 degrees and 25 degrees. How far apart are the two ships?
Answers
Answer:
189.8 m
Step-by-step explanation:
See the diagram attached.
Now, the plane is at B and the two ships are at C and at D.
So, angle of depression of C from B is ∠ OBC = ∠ ACB = 35°
Again, the angle of depression of D from B is ∠ OBD = ∠ ADB = 25° ,
Now, from the right triangle Δ ACB,
[tex]\tan 35 = \frac{AB}{AC} = \frac{265}{AC}[/tex]
⇒ [tex]AC = \frac{265}{\tan 35} = 378.5[/tex] m.
Similarly, from the right triangle Δ ADB,
[tex]\tan 25 = \frac{AB}{AD} = \frac{265}{AD}[/tex]
⇒ [tex]AD = \frac{265}{\tan 25} = 568.3[/tex] m.
Hence, the distance between the ships = CD = AD - AC = 568.3 - 378.5 = 189.8 m (Approx.) (Answer)
The distance apart is the two ships is 189.8 meters.
Given
A plane flying due east at 265 m above sea level, the angles of depression of two ships sailing due east measure 35 degrees and 25 degrees.
What is the angle of depression?The angle of elevation, the angle of depression is the angle at which you would draw a line from a point on a horizontal line to intersect another point that falls below the line.
The plane is at B and the two ships are at C and at D.
Then,
The angle of depression of C from B is ∠ OBC = ∠ ACB = 35°.
And the angle of depression of D from B is ∠ OBD = ∠ ADB = 25°.
From the right triangle Δ ACB,
[tex]\rm Tan35= \dfrac{AB}{AC}\\\\ AC= \dfrac{265}{Tan35}\\\\AC = \dfrac{265}{0.70}\\\\AC =378.57[/tex]
Again in the right triangle Δ ADB,
[tex]\rm Tan 25=\dfrac{AB}{AD}\\\\AD =\dfrac{265}{Tan25}\\\\ AD = \dfrac{265}{0.46}\\\\AD =569.30[/tex]
Therefore,
The distance apart are the two ships is;
= 568.3 - 378.5 = 189.8 m
Hence, the distance apart is the two ships is 189.8 meters.

What are the coordinates of the circumcenter?
A. (-1, 2.5)
B (-1/3, 3)
C (0, 3)
D (1, 4)
Answers
Answer:
option A (-1, 2.5) is correct
Step-by-step explanation:
Given
Let A(1, 1)
Let B(1, 4)
Let C(-3, 4)
Let coordinates of the circumcenter is (x, y)
Using distance formula
[tex]OA = OB[/tex]
[tex]OA^{2}=OB^{2}[/tex]
[tex](x-1)^{2}+(y-1)^{2} =(x-1)^{2}+(y-1)^{4}[/tex]
[tex]x^{2} +1-2x+y^{2} +1-2y=x^{2} +1-2x+y^{2} +16-8y[/tex]
[tex]8y-2y=16-1[/tex]
[tex]y=\frac{15}{6}[/tex]
[tex]y=2.5[/tex]
[tex]OA = OC[/tex]
[tex]OA^{2}=OC^{2}[/tex]
[tex](x-1)^{2}+(y-1)^{2} =(x-(-3))^{2}+(y-4)^{4}[/tex]
[tex](x-1)^{2}+(y-1)^{2} =(x+3)^{2}+(y-4)^{4}[/tex]
[tex]x^{2} +1-2x+y^{2} +1-2y=x^{2} +9+6x+y^{2} +16-8y[/tex]
[tex]-6x-2y-2x+8y=25-2[/tex]
put the y value in this equation
[tex]-8x+6\times\frac{15}{6} = 23[/tex]
[tex]-8x=23-15\\-8x=8\\x=-1[/tex]
So the coordinates of the circumcenter is (1, 2.5)
Midpoints: AB (1, 2.5), BC (-1, 4). Perpendicular bisectors: AB (y = 2.5), BC (x = -1). Intersection at (-1, 2.5), hence circumcenter is (-1, 2.5).
So, the correct answer is A. (-1, 2.5).
To find the circumcenter of a triangle, we can use the following steps:
1. Find the midpoints of two sides of the triangle.
2. Calculate the slopes of the perpendicular bisectors of those sides.
3. Use the midpoints and slopes to find the equations of the perpendicular bisectors.
4. Find the point of intersection of the perpendicular bisectors, which is the circumcenter.
Let's begin:
Given vertices of the triangle:
A (1, 1)
B (1, 4)
C (-3, 4)
1. Finding the midpoints of sides AB and BC:
Midpoint of AB = ((x1 + x2) / 2, (y1 + y2) / 2)
Midpoint of BC = ((x2 + x3) / 2, (y2 + y3) / 2)
Midpoint of AB = ((1 + 1) / 2, (1 + 4) / 2) = (1, 2.5)
Midpoint of BC = ((1 + (-3)) / 2, (4 + 4) / 2) = (-1, 4)
2. Calculate the slopes of the sides AB and BC:
Slope of AB = (y2 - y1) / (x2 - x1)
Slope of BC = (y3 - y2) / (x3 - x2)
Slope of AB = (4 - 1) / (1 - 1) = 3 / 0 (undefined slope)
Slope of BC = (4 - 4) / (-3 - 1) = 0 / -4 = 0
The slope of AB is undefined because the difference in x-coordinates is zero, meaning it's a vertical line. For a perpendicular bisector, we need to take the negative reciprocal of this slope.
3. Calculate the negative reciprocals of the slopes of AB and BC:
Negative reciprocal of undefined slope = 0
Negative reciprocal of zero slope = undefined
4. Equations of the perpendicular bisectors:
For AB: The perpendicular bisector passes through the midpoint (1, 2.5) and has a slope of 0.
Using the point-slope form of a line equation: y - y1 = m(x - x1)
y - 2.5 = 0(x - 1)
y = 2.5
For BC: The perpendicular bisector passes through the midpoint (-1, 4) and has an undefined slope (vertical line).
So, the equation is x = -1.
Now, we find the point of intersection of the perpendicular bisectors.
The point of intersection is the circumcenter.
Since the perpendicular bisectors intersect at (-1, 2.5), which is the midpoint of AB, the circumcenter is at (-1, 2.5).
So, the correct answer is A. (-1, 2.5).

The quotient in simplified form for \(\frac{15p^{-4}q^{-6}}{-20p^{-12}q^{-3}}\) is \(-\frac{3p^8}{4q^3}\). This is found by dividing the numerical coefficients and subtracting the exponents for variables of the same base (negative exponents indicate reciprocals).
Explanation:To find the quotient in simplified form for \(\frac{15p^{-4}q^{-6}}{-20p^{-12}q^{-3}}\), we perform division of the coefficients (15 divided by -20) and subtraction of the exponents for variables with the same base (p's and q's exponents) according to the rules of exponents. First, simplify the numerical coefficients:
\(\frac{15}{-20} = -\frac{3}{4}\)
Now, subtract the exponents for p (applying the formula x^p \cdot x^q = x^{(p+q)}):
\(p^{-4} - p^{-12} = p^{-4 + 12} = p^8\)
Next, apply the same process to the exponents of q:
\(q^{-6} - q^{-3} = q^{-6 + 3} = q^{-3}\)
Combine the results to get the simplified quotient:
\(-\frac{3}{4} × p^8 × q^{-3}\)
Remember that a negative exponent indicates a reciprocal, so we can write \(q^{-3}\) as \(\frac{1}{q^3}\). Therefore, the final answer is:
\(-\frac{3p^8}{4q^3}\)

Goran's gas tank is 1/3

Answers
Answer: 6 gallons
Step-by-step explanation:
1/3 = 2/6. 1/2 = 3/6
2/6 already + 3/6 = 5/6, it
To determine the total capacity of Goran's gas tank, we set up and solved an algebraic equation, finding that the total capacity of the tank is 18 gallons.
The student's question is about figuring out the total capacity of Goran's gas tank based on the information given. To solve this problem, we can set up a simple algebraic equation based on the proportions of the tank's capacity that are filled. Since filling the tank with 3 gallons of gas takes it from being 1/3 full to 1/2 full, we know that these 3 gallons represent the difference between 1/3 and 1/2 of the tank's total capacity.
Let's denote the total capacity of the tank as 'T' gallons. According to the question:
1/3 of 'T' + 3 gallons = 1/2 of 'T'We can now set up the equation:
1/3 * T + 3 = 1/2 * T
To find 'T', we need to solve for T:
1/2 * T - 1/3 * T = 3
This simplifies to:
(3T - 2T) / 6 = 3
T/6 = 3
Now multiply both sides by 6 to solve for T:
T = 18
Therefore, the total capacity of Goran's gas tank is 18 gallons.
Dawn has 5\6 yard of lace. She uses 4\5 of it on a dress and the rest on a jewel box. How much does she use on the jewel box
Answers
Answer:
Jewelry box: 1/6 yard
Step-by-step explanation:
4/5 (not 4\5) of her 5/6 yard goes into a dress: (4/5)(5/6 yd) = 2/3 yard.
This is the same as 4/6 yard. The amount of lace remaining, to be used on a jewelry box, is 5/6 - 4/6, or 1/6 yard.
Dawn used 1/6 yard of lace on the jewel box. This was calculated by subtracting the amount of lace used on the dress (2/3 yard) from the total lace available (5/6 yard).
Explanation:The subject of your question pertains to Mathematics, specifically fractions and their applications. To find out how much lace Dawn used on the jewel box, we need to subtract the amount of lace used on the dress from the total amount of lace. Dawn has 5/6 yard of lace and she utilized 4/5 of it on the dress. To find out the part used on the dress in the same unit, multiply the total lace (which is 5/6) by the part used (which is 4/5), so (5/6)*(4/5) = 20/30 or 2/3 yard. To find out what part of the lace was used on the jewel box, subtract the dress lace from the total lace. So, 5/6 - 2/3 gives us 1/6 yard of lace that is used on the jewel box.

14. You start an investment account with $3000 and save $100 each month. Write a
rule to represent the total amount of money you invest into your account as an
arithmetic sequence. How much money will you have invested after 12 months?
Answers
Answer:
4200
Step-by-step explanation:
In an arithmetic sequence equation t=a + (n-1)d, a is the starting value. In this case, a=3000.
Although, since the initial investment is not considered the first month, the equation is t = a + dn.
d is the rate of change. In this case, the rate of change is 100 for every month, n.
Substitute these values from the problem to get an equation:
t = 3000 + 100n
t means the total amount of money we have for the amount of months (n) that passed.
Sub n for 12.
t = 3000 + 100n
t = 3000 + 100(12)
t = 4200
You will have $4200 after 12 months of investment.

9.6, –4.8, 2.4, –1.2, 0.6, ...
f(n + 1) = –0.5f(n)
f(n + 1) = 0.5f(n)
f(n + 1) = f(0.5n)
f(n + 1) = f(–0.5n)
Answers
Answer:
f(n + 1) = –0.5f(n)
Step-by-step explanation:
The terms 9.6, –4.8, 2.4, –1.2, 0.6 alternate negative and positive. This means they must have a negative rate of change (because multiplying with negatives give both positive and negative numbers).
This narrows it down to:
f(n + 1) = –0.5f(n)
f(n + 1) = f(–0.5n)
Substitute f(n) for f(1)=9.6.
f(n + 1) = –0.5(n)
f(1 + 1) = –0.5(1)
f(2) = –0.5(9.6)
f(2) = -4.8
Since the second term is -4.8, f(n + 1) = –0.5f(n) is the recursive formula.
