4. If the landing angle at an airport is 4° and you are two miles out and ½ mile high, are you safe to land?
Yes, you are safe to land, If the landing angle at an airport is 4° and you are two miles out and ½ mile high.
Define the final approach.The final approach, also known as the final leg or final approach leg, is the last leg of an aircraft's approach to landing in aviation. During this leg, the aircraft is aligned with the runway and descending for a landing. In aircraft radio lingo, it is frequently abbreviated to "final".
Given,
If the landing angle at an airport is 4° and you are two miles out and ½ mile high,
Yes, you are safe to land.
A normal airport landing pattern calls for aircraft to turn from the base leg to the final within 0.5 to 2 miles of the airport when visual meteorological conditions (VMC) are present. A "straight-in" final approach, when all other legs are skipped, is frequently employed for instrument approaches as well as VFR approaches onto controlled airfields. At American non-towered airports, straight-in approaches are discouraged.

Answer: The correct answer is Option D: h=2A/(b1+b2)
Step-by-step explanation:
Solve for h:
a=(1/2h)(b1+b2)
Step 1: Flip the equation
1/2b^2h+1/2b1h=a
Step 2: Factor out variable h
h((b2+b1)/2)=a
Step 3: Divide both sides by (b^2+b1)/2
h((b2+b1/2))/(b2+b1/2)=(a/(b2+b1)/2)
h=2a/(b2+b1)

Answer:
16x² - 18x
Step-by-step explanation:
(25x² + 4 - 30x) - (9x² + 4 - 12x) ← distribute this parenthesis by - 1
= 25x² + 4 - 30x - 9x² - 4 + 12x ← collect like terms

24. The height of an object varies directly with the length of its shadow. If a tree 8 feet tall casts a shadow 10 feet long, how long will be the shadow of a tree that is 12 feet tall?
Answer:
15 feet
Step-by-step explanation:
Given an 8' object casts a 10' shadow, you want to know the length of the shadow of a 12' object.
ProportionThe shadow length is proportional to the object length:
shadow/object = 10'/8' = s/12'
Multiplying by 12', we have ...
s = (12')(10/8) = 15'
The shadow of a tree 12 feet tall will be 15 feet long.
r is a relation on the set of all nonnegative integers. (a,b) is in r if a and b have the same remainder when divided by 5
The relation accepts reflexive, symmetry, and transitive.
Recall that a relation R is reflexive if the element (x, x) belongs to R for all elements X in the domain of R.
If (x, y) belongs to R, then follows that (y, x) must likewise belong to R, making the situation symmetric.
And it is transitive if (x, y) and (y, z) belongs to R necessarily implies that (x, z) belongs to R.
Given r is a relation on the set of all nonnegative integers R(a,b)
Reflexive - YES. A given number a will always have the same remainder when divided by 5.
Symmetric - YES. If a and b have the same remainder when divided by 5, then b and a are the same pair, so again they will have the same remainder.
Transitive - YES. If a and b as well as b and c have the same remainder when divided by 5, this is possible if both a and c also have the same remainder when divided by 5.
Therefore the relation accepts reflexive, symmetry, and transitive.

Which of these strategies would eliminate a variable in the system of equations?
The strategy which would eliminate a variable in the system of equations is to multiply the top equation by -5 , then add the equation and is denoted as option B.
What is Equation?This is a mathematical term which is made up of two expressions and is connected by an equal sign.
In the example given below:
x - 2y = 11
5x + 3y = -11
We can multiply the top by -5 which will result in:
-5x + 10y = -55 after which it is added to the other to give:
-5x + 5x + 10y + 3y = -55 + (-11)
13y = -66
y = -66/13.
From this we can notice that the variable x was eliminated which is why option B is the correct choice.

Rectangle:
A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.
Here it is given that the measure of the rectangle is 238 cm and 435cm.
The Raegan creates a mural that is 27cm.
The formula to calculate the perimeter of a rectangle:
Perimeter = 2(length + breadth)
Earlier the length is 238cm and the breadth is 435cm.
Now replace the breath 435cm to 27cm.
length = 238cm
breadth = 27cm
Therefore we get the perimeter of the rectangle:
Perimeter = 2( 238 + 27)
= 2( 265)
=530cm
Therefore the perimeter is 530cm.

Step-by-step explanation:
This problem is solved using the Pythagorean theorem (a2+b2=c2). In this formula a and b are the legs of the right triangle while c is the hypotenuse.
Using the labels of our triangle we have:
o2+a2=h2
\dpi{100} h^{2}=(10ft)^{2} +(17ft)^{2}
h2=100ft2+289ft2
h=389ft2−−−−−√

A spinner with 9 equal sections is numbered 1 through 9. The probability of spinning a 3 is 1/9. What is the probability of not spinning a 3 is what
The probability of not spinning a 3 is 8/9
How to determine the probability that the number 3 is not spun?From the question, the given parameters are:
Number of sections = 9
Sections = Number 1 to 9
The probability of spinning a 3 = 1/9
The above probability can be represented as
P(3) = 1/3
The probability that the number 3 is not spun is the complement of the probability of spinning a 3
This is calculated as
P(3) + P(Not 3) = 1
Substitute the known values in the above equation So, we have the following equation
1/9 + P(Not 3) = 1
Evaluate the like terms
P(not 3) = 8/9
Hence, the probability is 8/9

The slope of the given graph x^2 = ln (xy) at the point (1, e) is e
We have been given a graph x^2 = ln (xy) and a point (1, e)
Differentiate the given graph on both sides
d/dx x^2 = d/dx (ln (xy))
⇒ 2x = 1/xy × d/dx (xy)
⇒ 2x × xy = x.dy/dx + y.dx/dx
⇒ 2x^2y = x.dy/dx + y
⇒ 2x^2y = x.dy/dx + y
⇒ 2x^2y - y = x.dy/dx
⇒ (2x^2y - y)/x = dy/dx … (1)
The slope at the point (1, e)
m = dy/dx at x = 1, y = e
Substitute the values in Equation (1)
⇒ m = (2(1)^2 (e) - e)/1
⇒ m = (2e - e)/1
⇒ m = e/1

The equation that models the function is y = 8/3(x) - 5/3.
Given:
The graph of a linear function passes through the point (-2, -7).
When the input increases by 3 the value of the function increases by 8.
(x,y) = (x+3,y+8)

The missing expression in step 2 should be [(6² + 2)/0.5] - 14.8 ÷ 8.
The missing expression in step 6 should be 76 - 1.85.
How to evaluate and solve the given expression?In order to evaluate this expression, we would apply the PEMDAS rule, where mathematical operations within the parenthesis are first of all evaluated, followed by exponent, and then multiplication or division from the left side of the expression to the right. Lastly, the mathematical operations of addition or subtraction would be performed from left to right.
For step 1, we have the following:
[(6² + 2)/|-0.5|] - 14.8 ÷ 8.
In step 2, we would take the absolute value of -0.5:
[(6² + 2)/0.5] - 14.8 ÷ 8.
Therefore, we would have the quantity of the sum of six squared (6²) plus two (2) divided by 0.25, minus 14.8 ÷ 8
In step 3, we would take the exponent of 6:
[(36 + 2)/0.5] - 14.8 ÷ 8.
In step 4, we would add 36 and 2 together:
[(38)/0.5] - 14.8 ÷ 8.
In step 5, we would divide 38 by 0.5:
76 - 14.8 ÷ 8.
In step 6, we would divide 14.8 by 0.5:
76 - 1.85
In step 7, we would subtract 1.85 from 76 as follows:
Solution = 76 - 1.85 = 74.15.

Answer:

Step-by-step explanation:
What is the slope of the line created by this equation? Round your answer out to the two nearest decimal places. 6x + 9y = 1
_____________________________________________
Slope intercept form solves for y:
y = mx + b when m = slope and b = y-intercept
First, solve for y:
6x + 9y = 1
subtract 6x from both sides:
6x + 9y - 6x = 1 - 6x
9y = 1 - 6x
divide both sides by 9:
9y/9 = (1 - 6x)/9
y = 1/9 - 6/9x
reduce right side:
y = 1/9 - 2/3x
rearrange right side:
y = - 2/3x + 1/9
Back to the equation: y = mx + b when m = slope and b = y-intercept
your slope is -2/3
