A cloud drifted above an airplane that was flying at 5,300 meters per minute. In 22.5minutes, the cloud moved 7,920meters to the east at a constant velocity. What was the cloud's velocity?
Answers
Answer is 352 metres
Step-by-step explanation:-The cloud is moving at a constant velocity. This means that we can find the velocity of the cloud by dividing the distance it moved by time:-
[tex]v = \frac{d}{t} [/tex]
Where "v" is velocity, "d" is distance and "t" is time.
The cloud moved 7920 metres in 22.5 minutes, so :-
[tex]v = \frac{7920 \: m}{22.5 \: min} [/tex]
[tex]v = 352 \: m/min[/tex]
Therefore, the cloud's velocity was 352 m/min.

What is an equation of the line that passes through the point ( − 3 , − 1 ) and is perpendicular to the line x − 2 y =6
Answers
Answer: y = -2x - 7
Step-by-step explanation:
The equation for a perpenducular line has a slope that is the negative inverse of the reference line, in this case x - 2y = 6.
Let's put this equation into standard slope-intercept form, y = mx+b, where m is the slope and b the y-intercept (the value of y when x is 0).
x - 2y = 6
- 2y = 6 - x
y = (1/2) x -3
The slope is (1/2), so a perpendicular line will have a slope of -2.
y = -2x + b
We can find b by using the given point ((-3,-1), a known solution):
-1 = -2*(-3) + b
-1 = 6 + b
b = -7
The perpendicular equation is y = -2x - 7
y = -2x

What are the three trigonometric reciprocals of sine, cosine, and tangent?
Answers
Answer:
Secant, cosecant and cotangent.
Step-by-step explanation:
Step-by-step explanation:
There are three reciprocal trigonometric functions, making a total of six including cosine, sine, and tangent. The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta).

Step-by-step explanation:
it's simple, just multiply
f.g(x)=(x^2-2)(4x+2)=4x^3+2x^2-8x-4
Step-by-step explanation:
Hi there!
f(x) = x²-2
g(x) = 4x+2
Then;
f(x).g(x) = (x²-2)*(4x+2)
= x²(4x+2) -2 (4x+2)
= 4x³ + 2x² - 8x - 4
Therefore, the answer is f(x).g(x)= 4x³ + 2x² - 8x - 4.

We can also think about it logically. For each suit, they have 3 different coats to wear. For each suit and coat combination, they have 4 different pairs of shoes to wear. So for each suit, there are 3 x 4 = 12 coat/shoe combinations. Since there are 6 different suits, they have 6 x 12 = 72 options.

You are considering hiring a DJ for a birthday party. The price of the DJ is $35 per hour. All customers must
pay a $75 set up fee. The fixed cost is added to the total bill.
Write an equation to determine the total bill, t, for a customer. Use h to represent the number of hours the DJ works.
t = 75h + 35
t = 35 + 75
t = 35h + 75
h = 35t + 75
Answers
Answer:
The answer is C
Step-by-step explanation:
t = bill for the customer
h= number of hours Dj worked
1) t = 75h + 35
This is wrong because h represents the number of hours the Dj worked. 75 is how much the customers paid as a setup fee.
2) t = 35 + 75
This is wrong because it's asking you to use "h" and "t" to determine the total. This is just a regular equation.
3) t = 35h + 75
This is right because as it says in the problem "The price of the Dj is $35 per hour" It also says use "h" to represent the number of hours the DJ works.
The "t" is used for the customer bill and 75 represents the setup fee
4) h = 35t + 75
This is wrong because h respresents how many hours the DJ works.
"t" represents the bill for the customer. The "t" would be in the beginning of the equation and the "h" would be behind the amount the DJ got paid per hour.

This diagram shows a pre-image △ABC, and its image, △A′′B′′C′′, after a series of transformations. Select from the drop-down menus to correctly complete the statements. △ABC is Choose... to become △A′B′C′. Then △A′B′C′ is Choose... to become △A′′B′′C′′ . Because the transformations are Choose... , the pre-image and image are Choose... . Triangles on a coordinate plane whose axes are labeled x and y. Triangle A B C has vertex A at 1 comma negative 1, vertex B at 4 comma negative 2, and vertex C at 7 comma 2. Triangle A prime B prime C prime has vertex A prime at negative 1 comma 1, vertex B prime at negative 4 comma 2, and vertex C prime at negative 7 comma negative 2. Triangle A double prime B double prime and C double prime has vertex A double prime at negative 1 comma negative 2, vertex B double prime at negative 4 comma negative 1, and vertex C double prime at negative 7 comma negative 5.
Answers
The answers that complete the statements of the series of transformations are;
- △ABC to △A′B′C′; because the △ABC has been rotated at angle of 180° about the origin.
- △A′B′C′ to △A′′B′′C′′; Because the △A′B′C′ has been shifted down by 3 units.
- All 3 transformations are rigid transformations
- All three transformations are congruent transformations.
The image showing triangles △ABC, △A′′B′′C′′, and △A′B′C′ is missing and so I have attached it.From the image attached, we see the following coordinates of the triangles;
Coordinates of △ABC; A(1, -1), B(4, -2), C(7, 2)
Coordinates of △A′B′C′; A'(-1, 1), B'(-4, 2), C'(-7, -2)
Coordinates of △A′′B′′C′′; A''(-1. -2), B''(-4, -1), C''(-7, -5)
Now, in transformation from △ABC to △A′B′C′, we see that the pattern of transformation is; (x, y) → (−x ,−y). This pattern where coordinates of x and y are transformed to the negative part of them denotes that there has been a rotation at angle of 180° about the origin.In transformation from △A′B′C′ to △A′′B′′C′′, we see that triangle shifted down because the y-coordinates have reduced by 3 units. Thus, we can say that the transformation was to shift △A′B′C′ down by 3 units.In each of the transformations, we can tell that regardless of the position of the triangle, the distances AB, BC and AC remain the same. Thus, the transformation is rigid. The transformations are also congruent because all their corresponding sides are equal.Read more at; https://brainly.com/question/11254677

Find the equation of the line through the point ( 3 , − 7 ) that is perpendicular to the line with equation y = x − 12 .
Answers
Answer: y = -x - 4
Step-by-step explanation:
A perpendicular line has a slope that is the negative inverse of the reference line, which is y = x-12. The slope here is 1, so the negative inverse would be -1/1, or -1. The perpendicular line would therefore be:
y = -1x + b
We can find b by using the given point (3,-7) as a solution:
y = -1x + b
-7 = -1*3 + b
b = - 4
The equation is therefore y = -x - 4
