Answer:
Line d : y = -3x - 3
Line e : y = -3x - 2
Line f : y= -3x + 2
Step-by-step explanation:
Given that,
The slope of each line is -3.
Now,
We know that,
Equation of line is represented by y = mx + c
where m is the slope and c is the y-intercept.
Now,
Given that,
Line d goes through (0, - 3) and (- 1, 0).
So,
y-intercept of Line d is -3
∴ we get
Equation of Line d is : y = -3x -3
Now,
Given that,
Line e goes through (-1, 2) and (0, -2).
So,
y-intercept of Line e is -2
∴ we get
Equation of Line e is : y = -3x - 2
Now,
Given that,
Line f goes through (0, 2) and (1, -1).
So,
y-intercept of Line e is 2
∴ we get
Equation of Line f is : y = -3x + 2
Answer:
The person above me is correct except for the fact that line e is wrong because I put it and is wrong

Ify is floating freely in outer space. The gravitational forces pulling on her body are negligible except for the forces from a nearby asteroid (a) the nearest planet (p) and the nearest star (s) The asteroid, planet, star, and Ify all lie in the same plane.
a= (2,4)
p=(-1.-3)
s=(8,2)
Answer:
The magnitude of the net gravitational force acting on Ify is 9.1 newtons.
Ify is getting pulled in a direction of 6.2 radians.
Step-by-step explanation:
The vector g = (9,-1) describes the net gravitational force acting on Ify.
We can find the magnitude of g, using the Pythagorean theorem.

Find the area: to the nearest whole number
Answer:
The area of the composite area is 400 square millimeters.
Step-by-step explanation:
The area of the composite figure ([tex]A[/tex]), in square millimeters, is found by multiplying the area of the equivalent rectangle, in which a semicircle of the original rectangle is move to the opposite side of the figure, so that quantity of area is conserved:
[tex]A = w\cdot h[/tex] (1)
Where:
[tex]w[/tex] - Width, in millimeters.
[tex]h[/tex] - Height, in millimeters.
If we know that [tex]h = w = 20\,mm[/tex], the area of the composite figure is:
[tex]A = (20\,mm)\cdot (20\,mm)[/tex]
[tex]A = 400\,mm^{2}[/tex]
The area of the composite area is 400 square millimeters.

the nearest tenth.
15 m
13 m
a.
b.
C.
d.
35.5 m
7.5 m
56 m
97.5 m
Answer:
35.5m
Explanation:
Find the diagram attached
First you need to get the missing side of the triangular pool using the pythagoras theorem;
Let the missing side be x
x² = 15² - 13²
x² = 225 - 169
x² = 56
x = √56
x = 7.48m
Amount of meter of fence needed is the perimeter of the triangular pool
perimeter of the triangular pool = 15 + 13 + 7.48
perimeter of the triangular pool = 35.48m
perimeter of the triangular pool = 35.5m
Hence the amount of meters of fence needed is 35.5m

18 is 4.5 times a number.
The value of x is equal to 4, that is 4.5 times 18 is 4
Given that the expression:
18 is equal to 4.5 times a number.
Assume that the number be x.
To find the number that is 4.5 times 18, we can set up the following equation:
4.5 × x = 18
Now, to find the value of x, divide both sides of the equation by 4.5:
4.5 × x / 4.5 = 18 / 4.5
x = 18 / 4.5
x = 4
So, the number that is 4.5 times 18 is 4.

The Large Hadron Collider is a tube formed into a circular loop measuring 4.3 km in diameter. It is used by physicists to accelerate atoms into each other to break them apart and observe new subatomic particles. An atom is accelerated 240 degrees around the loop before colliding with another atom. What is the distance that the atom traveled? Round your answer to the nearest hundredth. Units not necessary.
Answer:
9005.90 m
Step-by-step explanation:
The radius of the collider is half the diameter or 2150 m. The arc length S subtended by the angle is given by
S = r×(theta) where theta is the angle in radians. We need to convert the degree angle into radian angle using the following:
240° × (2pi/360°) = 4.19 radians
Therefore, the distance traveled by the atoms is so equal to the arc length S so
S = (2150 m)×(4.19 rad) = 9005.90 m

Answer:
Area = 12
Step-by-step explanation:
Given
See attachment
Required
Area of [tex]\triangle PQR[/tex]
From the attached image, we have:
[tex]P = (6,10)[/tex]
[tex]Q = (10,8)[/tex]
[tex]R = (6,4)[/tex]
The area is then calculated as:
[tex]A = \frac{1}{2}|(x1y2 - x2y1) + (x2y3 - x3y2) + (x3y1 - x1y3)|[/tex]
So, we have:
[tex]A = \frac{1}{2}|(6*8 - 10*10) + (10*4 - 6*8) + (6*10 - 6*4)|[/tex]
Using a calculator:
[tex]A = \frac{1}{2}|-24|[/tex]

Find the geometric mean of 16 and 36. Write your answer in simplest form. The geometric mean is
Answer:
Step-by-step explanation:
the geo. mean is the nth root of the product of n numbers
Here there are two numbers; geo. mean is the square root of their product
g = √(16 * 36)
g = 4 * 6
g = 24
Geometric mean is the mean which is the average of a set of a product.
The geometric mean of the given numbers is 24.
What is geometric mean?Geometric mean is the mean which is the average of a set of a product.
It can be given as,
[tex](\prod_{i=1}^{n}x_i)^{1/n}=\sqrt[n]{x_1\times x_2\times x_3...........x_n}[/tex]
Here [tex]x_i[/tex] is the values of the average and [tex]n[/tex] is the number of values.
Given information-
The numbers given in the problem is 16 and 36.
The Geometric mean for the number 16 and 36 has to find out.
Use the above formula to find the geometric mean for the number 16 and 36. Thus,
[tex]\prod=\sqrt{16\times36}[/tex]
[tex]\prod=\sqrt{576}\\\prod=24[/tex]

The multiplicative rate of change of the function is 1/5
From the table, we have the following ordered pairs
(x,y) = (1,2) and (2,2/5)
Divide the y values, to calculate the rate (r)

You randomly select 2 marbles from a mug containing 7 blue marbles, 3 red marbles, and 2 white marbles. How many times greater is the probability of selecting one blue marble and then one red marble when you do not replace the first marble before selecting the second marble than when you do replace the first marble before selecting the second marble? Express the answer as a fraction.
Answer:
Scenario 1: w/o replacement: P(blue, then red) = (7/12)(3/11) = 7/44
Scenario 2: w/ replacement: P(blue, then red) = (7/12)(3/12) = 7/48
