Let the function f(x) have the form f(x) = Acos(x + C). To produce a graph that matches the one shown below, what must the value of A be?
Answer: It’s 4 they’re all wrong (pretty sure I have the same graph)
Step-by-step explanation:
A general cosine function has the form:
f(x) = A*cos(c + x)
We want to find the value of A that matches the one in the image, and we will find that A = 3
Ok, a general cosine function is:
f(x) = A*cos(c + x)
Where A is the amplitude.
To find the amplitude of a cosine function, we just need to find half of the difference between the maximum and minimum value of the function:
By looking at the given graph, we can see that the maximum is y = 3, and the minimum is y = -3
Then the amplitude is:
A = (3 - (-3))/2 = 6/2 = 3
The correct option is B.

A plane rises from take-off and flies at an angle of 10 degrees with the horizontal runway. When it has gained 900 feet, find the distance, to the nearest foot, the plane has flown. An airplane is at vertex B of a right triangle that has a horizontal side AC, a vertical side BC of length 900 feet, and a dashed hypotenuse AB of unknown length c that rises from left to right. Angle C is the right angle and angle A measures 10 degrees. 10 degrees c equals question mark 900 ft A B C
Answer: The plane has flown 5,183 feet (approximately)
Step-by-step explanation: First and foremost, the plane is at vertex B of a right angled triangle ABC, and angle A measures 10°. Also the vertical side BC is the distance covered by the plane which in this case is the hypotenuse. The line BC is facing angle A which is the reference angle, hence line BC is the opposite.
With this bit of information we can calculate the distabce flown (hypotenuse) as follows;
Sin A = opposite ÷ hypotenuse
Sin 10 = 900/c
By cross multiplication we now have;
c = 900/Sin 10
c = 900/0.17364817766693
c = 5182.89
c ≈ 5183
Therefore the plane has flown 5,183 feet (approximately)
To find the distance the plane has flown, use the cotangent of the given angle (10 degrees) and multiply with the opposite side length (900 feet). The resulting value, rounded to the nearest foot, is the distance flown.
Explanation:In this scenario, we have a right triangle where it's given that the vertical side BC = 900 feet, the angle at A is 10 degrees, and we need to find the length of the hypotenuse AB (distance the plane has flown). For a right triangle, the trigonometric property that relates the angle with the sides is tangent (tan), defined as the ratio of the opposite side to the adjacent side.
However, in this case, we need to use its reciprocal function, cotangent (cot), which gives the ratio of the adjacent side to the opposite side. As we know the opposite side (900 feet) and the angle (10 degrees), we can find the length of the hypotenuse (AB) using the cotangent of the angle, i.e., cot(10 degrees) = AB/900. So, AB = cot(10 degrees) * 900.
On calculating the above expression and rounding to the nearest foot, you get the distance the plane has flown.

from the top of an 800 foot tall car talk tower, tom sees a plane; the angle of elevation is 67 degrees. at the same instant tay who is on the ground one mile from the building notes that his angle of elevation to the plane is 81 degrees and that his angle of elevation to the top of the tower is 8.6. assuming that tom and ray and the airplane are in a plane perpendicular to the ground, how high is the airplane
The airplane is approximately 33,336.6 feet above the ground. This calculation is based on Ray's perspective from 1 mile away with an 81-degree angle of elevation to the plane. The calculated height difference between the plane and the top of the tower is approximately 1,598.5 feet.
To solve this problem, we can use trigonometry to set up a system of equations with the given angles and the known height of the tower. We'll use the following steps:
1. Use Ray's angle of elevation to the plane (81 degrees) and his distance from the tower (1 mile, which is 5280 feet) to find the height of the plane from the ground.
2. Use Ray's angle of elevation to the top of the tower (8.6 degrees) with the same distance to find the height difference between the tower and the plane.
3. Add the height of the tower to the height difference found in step 2 to get the total height of the plane from the ground.
Let's denote the height of the plane from the ground as ( h ) and the horizontal distance from Ray to the point right below the plane as ( d ). We know that [tex]\( \tan(81^\circ) = \frac{h}{5280} \)[/tex] and [tex]\( \tan(8.6^\circ) = \frac{800}{5280} \)[/tex].
Let's calculate ( h ) using these equations.
The airplane is approximately 33,336.6 feet above the ground. This calculation is based on Ray's perspective from 1 mile away with an 81-degree angle of elevation to the plane. The calculated height difference between the plane and the top of the tower is approximately 1,598.5 feet.

find the value of x in given right triangle
Step-by-step explanation:
It is a right angled triangle so with reference angle 37°
hypotenuse (b) = 10
perpendicular (p) = x
So
tan 37° = p/ b
0.75 = x / 10
x= 0.75/10
Therefore x = 0.075
Hope it will help you :)
The value of x when rounded to nearest 10th will be 6.0
Given: a right angled triangle with hypotenuse equal to 10 units and angle opposite to the perpendicular equal to 37°
To find: value of the perpendicular [tex]x[/tex]
To find the perpendicular we can use trigonometric equation:
[tex]\sin \theta = \frac{\text{perpendicular}}{\text{hypotenuse}}[/tex]
where [tex]\theta[/tex] is the angle opposite to the perpendicular
Putting the values in the equation we get:
[tex]\sin 37 = \frac{x}{10}\\[/tex]
[tex]0.6018 = \frac{x}{10}\\[/tex]
[tex]x= 0.6018 \times 10\\x = 6.018[/tex]
So, the value of the perpendicular (x) is 6.018 units but when rounded to nearest 10th we get 6.0

A firefighter is standing on the middlemost rung of a ladder, extinguishing a fire. In order to get a better position, the firefighter climbs 6 rungs. But due to the flames, the firefighter climbs down 10 rungs. After the fire calms down the firefighter climbs 18 rungs to reach the top rung.
How many rungs did the ladder have?
Answer:
29 rungs
Step-by-step explanation:
In this question, we are to use the climbing statistics of a firefighter to determine the number of rungs a ladder have.
Firstly, since we do not know the number of rungs but we know we are starting from the middle rung, let the middle rung be r.
From the middle rung, he climbed 6 rungs, meaning he would be on rung x + 6 ! From here he came down ten rungs, meaning he would be on rung x + 6 - 10 = x -4
Now, he climbed 18 rungs again, making x -4+18 = x + 14
This is equal to the topmost rung i.e the topmost rung is at a position x + 14
This means that the ladder must have 14 rungs above the middle , 14 below it and the middle itself
14+ 14 + 1 = 29 rungs
The firefighter's movements on the ladder suggest that the ladder has 41 rungs, confirmed by algebraically considering the middle rung 'm' and then solving for 'm' knowing the positions relative to the top.
To solve the question, let's follow the firefighter's movement on the ladder using variables and a step-by-step approach. If we let the middlemost rung the firefighter is initially standing on be represented by 'm,' we can track the rung positions with the following moves:
The firefighter climbs up 6 rungs: new position is m + 6.
The firefighter then climbs down 10 rungs: new position is (m + 6) - 10 = m - 4.
Finally, to reach the top of the ladder, the firefighter climbs up 18 rungs: new position is (m - 4) + 18 = m + 14.
Since the final position is the top rung of the ladder, it means the middlemost rung 'm' plus 14 rungs equals the total number of rungs on the ladder. Because 'm' is the middle rung of the ladder, there must be 'm - 1' rungs below it. Therefore, the total number of rungs on the ladder is (m - 1) + m + 14. Simplifying, this becomes 2m + 13.
Now we know that 2m equals the number of rungs minus the top 14 rung positions, and since 'm' represents the middlemost rung, '2m' represents the total number of rungs on the ladder except for the top 14. Hence, the total rungs on the ladder are 2m + 14. But since 2m + 13 equals the total, the only number that satisfies this condition is when m = 14. Therefore, the ladder must have 2m + 13 = 2(14) + 13 = 41 rungs.

A teacher works for a textbook company during the summer. She makes $35 per page to write the material and $25 per page to type it. The teacher would like to earn at least $3200, but does not want more than 120 pages of work. Let "x" represent the number of pages written and "y" represent the number of pages typed. Write a system of inequalities to represent this situation.
Answer:
$35 x + $25 y ≥ $3200 x ≤ 120
Step-by-step explanation:
Because she needs to write before type the page, so that y≤x
∴ x≤120
$35 x + $25 y ≥ $3200 x ≤ 120
Final answer:
The system of inequalities for the teacher's summer work with the textbook company is 35x + 25y \\( ext{≥}) 3200, x + y \\( ext{≤}) 120, x \\( ext{≥}) 0, and y \\( ext{≥}) 0, where x is pages written and y is pages typed.
Explanation:
The system of inequalities to represent the situation where a teacher works for a textbook company during the summer, earns $35 per page for writing the material and $25 per page for typing, wants to earn at least $3200, and does not want more than 120 pages of work would be:
35x + 25y \\( ext{≥}) 3200
x + y \\( ext{≤}) 120
x \\( ext{≥}) 0
y \\( ext{≥}) 0
Here, x represents the number of pages written and y represents the number of pages typed. The first inequality ensures the teacher earns at least $3200, the second inequality ensures the total number of pages does not exceed 120, and the last two inequalities represent that the teacher cannot write or type a negative number of pages.

Answer:
D) the value of the exponential function will eventually exceed the value of the linear function.
Step-by-step explanation:
I ATTACHED AN IMAGE WITH THE CORRECT INFORMATION OF THE QUESTION.
To know which is the correct answer we can calculate some other values of f(x) and g(x) for higher values of x:
f(100)=210 g(100)=7.31
f(1000)=2010 g(1000)=20959.15
f(10000)=20010 g(10000)=1.63e^43
As we can observe, g(x) eventually will exceed to f(x). This is noticed when x = 1000, where g(1000)>f(1000).
Hence, the answer is:
D) the value of the exponential function will eventually exceed the value of the linear function.
What is 3x+2y=15 y=6x
Final answer:
The solution to the system of equations is x = 1 and y = 6.
Explanation:
The given equations are:
3x + 2y = 15
y = 6x
To solve this system of equations, we can substitute the value of y from the second equation into the first equation:
3x + 2(6x) = 15
3x + 12x = 15
15x = 15
x = 1
Substituting the value of x into the second equation to find y:
y = 6(1)
y = 6
So, the solution to the system of equations is x = 1 and y = 6.
