A fighter pilot needs to make an emergency landing. He needs a clear space that is at least 600 m long to land safely. He is flying at an altitude of 300 m. He sees a small empty field. The angles of depression from the jet to the two ends of the field are 30° and 56° [5]
a) How long is the field?
b) Can he land safely?
Answers
(a) See the attached sketch. The jet makes a right triangle with the ground with hypotenuse y. Since the angle of depression is 56°, and the plane in which the jet is flying 300 m in the air is parallel with the ground, the angle of elevation in the right triangle is also 56°. Use the definition of sine to solve for y.
sin(56°) = (300 m)/y → y = (300 m)/sin(56°)
The uppermost angle in the blue triangle has measure equal to the difference between the two given angles of depression, 56° - 30° = 26°, and the rightmost angle is also 30° by the same reasoning as before. Then by the law of sines,
x/sin(26°) = y/sin(30°) → x = sin(26°)/sin(30°) y ≈ 317.2627 m
(b) No, the field is not long enough.

82
Answers
50 + 82 = 132
a triangle is 180°
180 - 132 = 48
therefore the correct answer would be 48°
Answer:
48⁰
Step-by-step explanation:
TAKE NOTE: The sum of interior angles of a triangle equals 180.
STEP 1: SET UP YOUR EQUATION
x + 50 + 82 = 180
STEP 2: SOLVE
x + 50 + 82 = 180
x + 132 = 180
x = 48

Answer:
Our final answer is the average speed is 7 and 2/3 miles per hour
Step-by-step explanation:
We want to find the speed of Maria's bike (miles per hour). Realize that 3/4 of an hour is 45 minutes. So if we take the total miles (5 and 3/4 miles) and divide by 45 mins, we will get the total miles per min.
We can convert 5 and 3/4 miles to a single fraction -----> 5 and 3/4 = 5 +3/4 = 5/1 + 3/4 = 20/4 + 3/4 = 23/4
Now we take 23/4 and divide this number by 45. ( or multiply by 1/45). This answer is 23/180 and THIS NUMBER represents the total amount of MILES PER MIN. BUUUTT we want the total amount of MILES PER HOUR. What do we do?
We take the total miles per minute and multiply this answer (23/180) by 60 minutes [60 mins = 1 hour].
Thus (23/180)*60 = 1380/180 ----------> which is equal to 1260/180 + 120/180 = 7 + 2/3 = 7 and 2/3
Our final answer is the average speed is 7 and 2/3 miles per hour

Answers
Answer:
A
Step-by-step explanation:
trust me
The required percentage that Cortney got correct on the test will be; 85.33%.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
We have been given that Cortney got 64 out of 75 correct on a test.
We Need to determine the best estimate of the percentage Courtney got correct.
Here,
The Total question = 75
The correct question = 64
Then Percentage = 64 / 75 × 100
Percentage = 85.33%
Thus, the required percentage that Cortney got correct on the test will be; 85.33%.

"Frank's favorite drink is coke, but the restaurant only has Pepsi." Simple or Compound sentence?
Answers
Answer:
Compound sentence
Step-by-step explanation:
A compound sentence is a group of words that consists of at least two independent clauses. The main difference between simple and compound sentences is that a simple sentence is composed of a single clause whereas a compound sentence is composed of two or more clauses. This means that it's a compound since "Frank's favorite drink is coke" is the first independent clause, and "but the restaurant only has Pepsi", is the second independent clause.

Given the parent function f(x) = 8x + 9, rewrite the function after the following transformation: reflect over the x-axis. Group of answer choices g(x) = -8x + 9 g(x) = -8x - 9 g(x) = 8x - 9 g(x) = 8x + 9
Answers
Given:
The parent function is
[tex]f(x)=8x+9[/tex]
To find:
The function after the reflection over the x-axis.
Solution:
We know that, if a function f(x) reflected over x-axis to get the function g(x), then
[tex]g(x)=-f(x)[/tex]
Putting [tex]f(x)=8x+9[/tex], we get
[tex]g(x)=-(8x+9)[/tex]
[tex]g(x)=-8x-9[/tex]
The function after the reflection over the x-axis is [tex]g(x)=-8x-9[/tex].
Therefore, the correct option is B.
What are the coordinates of point H?
Answers
9514 1404 393
Answer:
(-1 1/2, 3)
Step-by-step explanation:
Coordinates are written as an ordered pair. That means the position of the coordinate value in the pair has significance.
By convention, the first coordinate is the "x" coordinate. It is the number of units the point lies to the right of the x=0 point on the horizontal scale. Here, the point lies between 1 and 2 units left of 0, corresponding to an x-coordinate of -1 1/2. So far, we know the point coordinates are (-1 1/2, <something>).
At this point, you can check to see if this narrows down the answer choices. It does. The only available answer choice with a first coordinate of -1 1/2 is the correct one: (-1 1/2, 3).
__
The second coordinate in the ordered pair is the "y" coordinate. It is the number of units the point lies above the point y=0 on the vertical scale. Here, the point lies 3 units above the point y=0, corresponding to a y-coordinate of 3. Now, we know the coordinates of the point are (x, y) = (-1 1/2, 3).
_____
Additional comment
Ordered pairs of coordinates are not always x- and y- coordinates. Sometimes, they are elevation and azimuth, latitude and longitude, radius and angle. However, for the vast majority of work in Algebra, an ordered pair of coordinates refers to (x, y) coordinates on a Cartesian plane (one with grid lines running horizontally and vertically).

The difference between 32.6 and a number is 10.2. Which equation can be used to solve this problem? 32.6 minus y = 10.2 y minus 36.2 = 10.2 10.2 minus y = 32.6 y + 32.6 = 10.2
Answers
Answer:
32.6 - y= 10.2
Step-by-step explanation:
The equation to solve this problem can be written as
32.6 - y= 10.2
Where y is the number that was substracted from 32.6.
If we make y subject of formula we have
y= (32.6-10.2)
y=22.4
Which means the number that was substracted from 32.6 is 22.4 and there difference is 10.2

Answer:
How many plates are on the table as it results in only one value with no variability
Step-by-step explanation:
D) How many plates are on the table? is not a statistical question because it does not involve the collection or analysis of numerical data.
What is Statistic?A statistic is a piece of data derived from a subset of a population. It's the inverse of a parameter — census data, which polls everyone.
Statistics is a method of comprehending data collected about us and the world. For example, if you send a parcel through the mail, it is logged in a massive database.
How many plates are on the table? is not a statistical question because it does not involve the collection or analysis of numerical data.
A statistical question involves the collection and analysis of numerical data in order to make inferences or draw conclusions about a larger population.
The other questions (A, B and C) all involve the collection and analysis of numerical data and are therefore statistical questions.
Hence, the correct answer would be option (D).
