An observer (O) spots a plane flying at a 55° angle to his horizontal line of sight. If the plane is flying at an altitude of 21,000 ft., what is the distance (x) from the plane (P) to the observer (O)?
Answer:
Step-by-step explanation:
The givens form a right triangle. The operational definition is The opposite over the hypotenuse, where the hypotenuse is the unknown.
sin(x) = 21000/hypotenuse
sin(55) = 21000 / hypotenuse
hypotenuse * sin(55) = 21000
hypotenuse = 21000/sin(55)
hypotenuse = 25636 feet.= 26000 feet rounded.
The answer does make sense. The hypotenuse is larger than the given height.

Algebra questions.
if x=3 then 2x3-2=4
So if it WAS 3 then Y would be 4
Precalc Help me Please
We just need to solve for y when x = -2
Solution:
y = 2|-2 + 1|
y = 2|-1|
y = 2(1)
y = 2
Therefore, the answer is Option 3

given the following functions f(x) and g(x), evaluate (gºf)(-2). Enter answer.
f(x)=2x^2+2x-5
g(x)=-1/-4x+6
Answer:
the composition results in [tex]\frac{23}{4}[/tex]
Step-by-step explanation:
Assuming that what you typed for function g is correct (looks a bit peculiar, but we will use it as typed):
[tex]g(x)=-\frac{1}{-4x} +6[/tex]
gof(-2) can be understood as: g(f(-2)), so what we need to do is to find the value for f(-2) using its given expression, and using then the obtained value as input for g(x):
[tex]f(x)=2x^2+2x-5\\f(-2)=2\,(-2)^2+2\,(-2)-5\\f(-2)= 8-4-5\\f(-2)= -1[/tex]
So, we now evaluate g(-1):
[tex]g(x)=-\frac{1}{-4x} +6\\g(-1)= -\frac{1}{-4(-1)} +6\\g(-1)= -\frac{1}{4} +6\\g(-1)=\frac{23}{4}[/tex]

Use the map to find the distance between Brookline and Davenport to the nearest tenth
Answer:
8.5
Step-by-step explanation:
The distance between Brookline(8, 2) and Davenport(5, 10) can be calculated using the distance formula given as [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y1)^2} [/tex].
Let,
[tex] Brookline(8, 2) = (x_1, y_1) [/tex]
[tex] Davenport(5, 10) = (x_2, y_2) [/tex]
[tex] d = \sqrt{(5 - 8)^2 + (10 - 2)^2} [/tex]
[tex] d = \sqrt{(-3)^2 + (8)^2} [/tex]
[tex] d = \sqrt{9 + 64} = \sqrt{73} [/tex]
[tex] d = 8.5 [/tex] (nearest tenth)

Which expression is equivalent to 2(n - 7) - 3(2 -6n)
20(n - 1)
Step-by-step explanation:2(n - 7) - 3(2 -6n) =
= 2n - 14 - 6 + 18n
= 20n - 20
= 20(n - 1)
The value of the equation A = 2(n - 7) - 3(2 -6n) is
A = 20 ( n- 1 )
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be A
Now , the equation A = 2( n - 7 ) - 3( 2 - 6n )
The equation can be simplified as
A = 2(n) - 2(7) - 3(2) + 3(6n)
A = 2n - 14 - 6 + 18n
Now , on adding the similar terms in the equation , we get
A = 2n + 18n - ( 14 + 6 )
A = 20n - 20
Taking the common term of 20 , we get
A = 20 ( n - 1 )
Therefore , the value of A is 20 ( n - 1 )
Hence , The value of the equation A = 2(n - 7) - 3(2 -6n) is A = 20 ( n- 1 )

-axis to create point U'. What ordered pair describes the location of U'?
Given :
A point U located at (1,-4) on the coordinate plane.
To Find :
The reflection of point U on x-axis.
Solution :
Reflection of any point ( h , k ) on x-axis is ( h , - k ) .
So , the reflection of point U i.e ( 1 , -4 ) is ( 1 , 4 ) .
Therefore , the ordered pair describes the location of U' is ( 1 , 4 ).

Find the midpoint of the segment with the following endpoints.
(5,9) and (0,3)
Answer:
(5/2, 6)
Step-by-step explanation:
(x, y)=[(5+0)/2, (9+3)/2]
(x, y)=[5/2, 12/2]
(x, y)=(5/2, 6)
The Midpoint of the Line Segment that has the endpoints (5,9) and (0,3) is (5/2,6).
What is the line segment?In geometry, a line segment is a part of a line that is bounded by two end points, and contains every point on the line that is between end points.
Now it is given that,
The endpoints of line segment is (5,9) and (0,3)
So, x₁ = 5
y₁ = 9
x₂ = 0
y₂ = 3
Let (x,y) be the midpoint of segment .
∴To find the midpoint of segment we have,
(x,y) = {[(x₁+x₂ )/2] , [(y₁+y₂ )/2]}
Put the values, we get
(x,y) = (5+0)/2 , (9+3)/2
solving them,
(x,y) = {(5/2) ,(12/2)}
or,
(x,y) = (5/2,6)
which is the required midpoint of the line segment.
Hence,the Midpoint of the Line Segment that has the endpoints (5,9) and (0,3) is (5/2,6).
