Answer:
The coordinates of the P' point are (-17.3,-10).
Step-by-step explanation:
We can use the components of the vector from 0 to P point. We know that the diameter is 40 meters, so the magnitude of the vector will be 20 m.
Now, the angle from the negative x-direction to the vector is 210°-180° = 30°.
The x-component of the vector will be:
[tex]V_{x}=-Vcos(30)[/tex]
[tex]V_{x}=-20cos(30)=-17.32\: m[/tex]
It is negative because the component is in the negative x-direction.
The y-component of the vector will be:
[tex]V_{y}=-Vsin(30)[/tex]
[tex]V_{y}=-20sin(30)=-10\: m[/tex]
It is negative too because the component is in the negative y-direction.
Therefore, the coordinates of the P' point are P'(-17.3,-10)
I hope it helps you!
What is the volume of a cube with 3-inch edges, in cubic inches?
Answer:
Sorry don't know sis I am really sorry
Answer:
volume is the area multiplied by the depth. We also know it's a club so it's one side of 3 is true for all sides and depth.
its 3 x 3 x 3... which is 9 x 3 which is 27.

Help please, I really need help please
Answer:
-70
Step-by-step explanation:
As shown in the picture, you can use the formula:
1st term + common difference(desired term -1)
From what is given, we can see that the first term is -2. We are looking for the 18th term, so 18 is our desired term. Lastly, to find the common difference, we can subtract a the term before a certain term from it:
common difference = -6 - (-2) = -4
Now, we can substitute what we have:
-2 + (-4)(18 - 1)
-2 - 4(17)
-2 - 68
-70
25 POINTS GIVING BRAINLIEST TO WHOEVER ANSWERS UT RIGHT!!A right triangle has hypotenuse with a length of 13 cm. The length of one leg is 5 cm. What is the area of the triangle?
A.65
B.60
C.32.5
D.30
Answer:
Hello! answer: 30
Step-by-step explanation:
13 × 13 = 169
5 × 5 = 25
169 - 25 = 144
12 × 12 = 144 therefore 12 is the missing leg
so we will use this to find the area so...
12 × 5 = 60 60 ÷ 2 = 30 therefore the answer is 30 hope that helps!
Which tables could be used to verify that the functions they represent are inverses of each other? Select two
options.
Why? Because they are mirrors of each other. In other words, one table has its x and y row swapped compared to the other table.
The input x = -120 leads to the output y = 627 in table C. Then in table D, we have the input x = 627 to go the output y = -120. Refer to the first column of each table mentioned. The same applies for the other columns as well. The inverse table undoes everything the original table does.
The tables that could be used to verify inverse functions are tables C and D
What are inverse functions?The inverse of a function are the opposites of the function
From the list of options, we can see that:
The x values of table C are the y values of table D
Also, the x values of table D are the y values of table C
This means that tables C and D are inverse functions
Hence, the tables that could be used to verify inverse functions are tables C and D

2. 2
A. y=2x-1
B. y=x + 10
C. y=3x -4
D. y=2x + 1
C. y = 3x - 4
Step-by-step explanation:
Given coordinates:
(2, 2), (3, 5), (5, 11), (7, 17)
The equation of any straight line is
y = mx + c
Where
m = Gradient
c = Constant
Gradient = y2 - y1/x2 - x1
Substitute any two values of y with the respective values of x.
Gradient = 17 - 2/7 - 2
= 15/5
= 3
Substitute the gradient into the general formula.
y = 3x + c
Substitute any value of the coordinate to the equation
2 = 3(2) + c
2 = 6 + c
c = -4
From y = mx + c,
substitute the values of m, the gradient, and c, the constant.
y = (3)x + (-4)
y = 3x - 4

Convert 4x-2y=6 into slope intercept form
Answer:
y=2x-3
Step-by-step explanation:
first, you have to get the y by itself (isolate the y). you do this by subtracting 4x from both sides.
4x-2y=6
-2y=-4x+6
next, you have to divide both side by -2 to isolate the y further and get this into slope-intercept form:
-2y=-4x+6
y=2x-3

What are the lengths of each segment? Thank you!
Answer:
[tex]\displaystyle a=\sqrt{17}\text{ units} \text{ and } b=3\sqrt{2}\text{ units}[/tex]
Step-by-step explanation:
To determine the distance between any two points, we can use the distance formula. The distance formula is given by:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
a is the distance between the points (-2, 3) and (-1, -1). Let (-2, 3) be (x₁, y₁) and let (-1, -1) be (x₂, y₂). Substitute and evaluate:
[tex]\begin{aligned} a&=\sqrt{(-1-(-2))^2+(-1-3)^2}\\\\&=\sqrt{(1)^2+(-4)^2}\\\\&=\sqrt{1+16}=\sqrt{17}\text{ units} \end{aligned}[/tex]
b is the distance between the points (2, 2) and (-1, -1). Again, we can let (2, 2) be (x₁, y₁) and (-1, -1) be (x₂, y₂). Substitute and evaluate:
[tex]\displaystyle \begin{aligned} b&=\sqrt{(-1-2)^2+(-1-2)^2}\\\\&=\sqrt{(-3)^2+(-3)^2}\\\\&=\sqrt{9+9}=\sqrt{18}=\sqrt{3^2\cdot 2}=3\sqrt{2}\text{ units}\end{aligned}[/tex]

In a test, +3 marks are given for every correct answer and -1 are given for every incorrect answer (i) Sona scored +20 marks though she got 10 correct answers. How many incorrect answers has she attempted??
Answer:
10 incorrect answers
Step-by-step explanation:
Correct answer = +3
Incorrect answer = - 1
Mark scored = 20
Number of correct answers = 10
Let:
Incorrect answers = y
Hence, we can fashion out the expression for total score :
(Number of correct answers * score per Correct answer + number of incorrect * score per incorrect) = total score
(10 * 3) + (y * - 1) = 20
30 - y = 20
-y = 20 - 30
-y = - 10
y = 10

whats the slope of this
Answer:

(2-0)/(1+2)

Answer:
slope = [tex]\frac{2}{3}[/tex]

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (1, 2) ← 2 points on the line

c. f(-x) =
(Simplify your answer.)
Step-by-step explanation:
The given function is :
[tex]f(x)=x^2-5x+ 5[/tex]
(a) To find f(9), put x = 9 in the above expression.
[tex]f(9)=9^2-5(9)+ 5=41[/tex]
(b) To find f(x+7), put x = x+7 in the above expression.
[tex]f(x+7)=(x+7)^2-5(x+7)+ 5\\\\=x^2+14x+49-5x-35+5\\\\=x^2+9x+19[/tex]
(c) To find f(-x), put x = -x in the above expression.
[tex]f(-x)=(-x)^2-5(-x)+ 5\\\\=x^2+5x+5[/tex]
Hence, this is the required solution.

A bag contains 4 yellow, 2 red, and 6 green marbles. two marbles are drawn. the first is replaced before the second is drawn. a random variable assigns the number of red marbles to each outcome. calculate the expected value of the random variable.
a. 0.67
c. 0.17
b. 0.56
d. 0.33
Answer:
c. 0.17
Step-by-step explanation:
The bag have 4 + 2 + 6 = 12 balls.
There are 2 red marbles, in 12, the probability to take one red is 2/12. Is important to remember that the first marble was replaced before the second outcome, so the chance for the second is also 2/12:
2/12 = 1/6 = 0.1666 ≈ 0.17
The expected value of the random variable that assigns the number of red marbles to each outcome is 0.17.
What is the probability?Probability is used to estimate how likely an event would happen. The probability the event occurs with certainty is 1 and the probability that the event does not occur with certainty is 0.
Expected value = number of red marbles / total number of marbles
2/12 = 0.17
