Answer:
m = 1/2
Step-by-step explanation:
To find the slope, all you have to do is find the rise and divide it by the run. Rise means how many units you move up or down from point to point. Run means how far left or right you move from point to point.
You can pick any two points on the line. Let's say I choose (10, 5) and (20, 10).
Let's look at the y coordinates first. You have 5 and 10. To get from 5 to 10, you have to go up 5 units. Your rise is 5. Let's look at the x coordinates now. To get from 10 to 20, you have to go up 10 units. Your run is 10.
As I said before, the slope is rise/run. In this case, we have 5/10, which can be simplified to 1/2. Your slope is 1/2.
Note that any two points on this would give you the same answer of 1/2 for this line. If I had picked (30, 15) and (70, 35), I would still get 1/2.
Hope this helped!

Transitive property of segment congruence
Step-by-step explanation:
The reflexive, symmetric, and transitive properties are the criterion for an equivalence relation. In terms of congruence,
The reflexive property states that [tex]\overline{XY} \cong \overline{XY}[/tex] (a segment is congruent to itself)The symmetric property states that if [tex]\overline{AB} \cong \overline{CD}[/tex], then [tex]\overline{CD} \cong \overline{AB}[/tex] (this is essentially commutativity)The transitive property states that if [tex]\overline{AB} \cong \overline{CD}[/tex] and [tex]\ovelrine{CD} \cong \overline{EF}[/tex], then [tex]\overline{AB} \cong \overline{EF}[/tex].In terms of general equivalence relations,
The reflective property states that [tex]a = a[/tex].The symmetric property states that if [tex]a=b[/tex], then [tex]b=a[/tex].The transitive property states that if [tex]a=b[/tex] and [tex]b=c[/tex], then [tex]a=c[/tex].That's the transitive property.
The fact that congruence is transitive means exactly what you have written: if A is congruent to B and B is congruent to C, then you can "bridge" from A to C.
A meat packer has 180 kilograms of ground meat. He will divide it equally into 50 packages. How much will each package weigh?
Answers
Answer:
3.6 kg
Step-by-step explanation:
A meat packer has 180 kilograms of ground meat. He will divide it equally into 50 packages. How much will each package weigh??
Since he is dividing equally, we have:
50 packages = 180 kg
1 package = x kg
Cross Multiply
x kg × 50 packages= 180kg × 1 packages
x kg = 180 kg × 1/50 packages
x kg = 3.6 kg
Hence, 1 package would weigh 3.6 kg(kilograms)
Solve for x

Find a cubic function f(x) = ax3 + bx2 + cx + d that has a local maximum value of 3 at x = −3 and a local minimum value of 0 at x = 1.
Answers
Answer:
The cubic function is f(x) = (27/32)·x - 3/32·x³ - -9/32·x² - 9/32
Step-by-step explanation:
The given function is f(x) = a·x³ + b·x² + c·x + d
By differentiation, we have;
3·a·x² + 2·b·x + c = 0
3·a·(-3)² + 2·b·(-3) + c = 0
3·a·9 - 6·b + c = 0
27·a - 6·b + c = 0
3·a·(1)² + 2·b·(1) + c = 0
3·a + 2·b + c = 0
a·(-3)³ + b·(-3)² + c·(-3) + d = -3
-27·a + 9·b - 3·c + d = -3...(1)
a + b + c + d = 0...(2)
Subtracting equation (1) from equation (2) gives;
28·a - 8·b + 4·c = 3
Therefore, we have;
27·a - 6·b + c = 0
3·a + 2·b + c = 0
28·a - 8·b + 4·c = 0
Solving the system of equations using an Wolfram Alpha gives;
a = -3/32, b = -9/32, c = 27/32 from which we have;
a + b + c + d = 0 3 × (-3/32) + 2 × (-9/32) + (27/32) + d = 0
d = 0 - (0 3 × (-3/32) + 2 × (-9/32) + (27/32)) = -9/32
The cubic function is therefore f(x) = (-3/32)·x³ + (-9/32)·x² + (27/32)·x + (-9/32).

[tex]\large\boxed{h(x) = 4x + 48}[/tex]
[tex]f(x) = \frac{1}{4}x - 12[/tex]
Find the inverse. Begin by swapping the x and y (f(x)) variables:
[tex]x= \frac{1}{4}y - 12[/tex]
Begin isolating for y. Add 12 to both sides:
[tex]x + 12 = \frac{1}{4}y[/tex]
Multiply both sides by 4:
[tex]4(x + 12) = \frac{1}{4}y * 4[/tex]
[tex]4x + 48 = y[/tex]
Therefore:
[tex]h(x) = 4x + 48[/tex]

which equation represents a line that is perpendicular to line FG
Answers
Note: You missed to add some basic information of the perpendicular line or missed the answer options, hence I am solving using a sample equation but it would clear your concept.
Answer:
Please check the attached graph.
Step-by-step explanation:
We know the slope-intercept form of line equation is
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
Given the points
F(1, 8)G(-3, -4)Finding the slope between F(1, 8) and G(-3, -4)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(1,\:8\right),\:\left(x_2,\:y_2\right)=\left(-3,\:-4\right)[/tex]
[tex]m=\frac{-4-8}{-3-1}[/tex]
[tex]m=3[/tex]
Thus, the slope of the line FG = m = 3
From the given line, we can also determine the y-intercept 'b' by setting x = 0 and checking the corresponding y value.
i.e. at x = 0, y = 5
Thus, y-intercept b = 5
so substituting m = 3 and b = 5 in the slope-intercept form
y = mx+b
y = 3x+5
Therefore, the equation of line FG will be:
y = 3x+5Please check the attached diagram, where the red line represents the line y=3x+5
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line.
Slope of Perpendicular line = -1/m = -1/3
Thus, any line with the slope m = -1/3 would be the line that will be perpendicular to line FG
Let say the line with the slope m = -1/3 and y-intercept 2
y = -1/3x + 5
Please check the attached graph, the blue line is representing the perpendicular line y = -1/3x + 5 to line FG
The graph of both lines is clearly representing that the line y = -1/3x + 5 is perpendicular to line FG.

Answers
Answer: 1.55%
Step-by-step explanation:
p = Principal = $40000
r = Interest rate = 1.55% = 0.0155
n = Number of periods = 365
APY = [1 + (r/n)^n - 1]
= [1 + (0.0155/365)^365 - 1]
= [1 + 0.000042)^365 - 1]
= [1.000042]^365 - 1
= 1.015448 - 1
= 1.55%

An Airplane is ascending at a speed of 400 km/hr along a line making an angle of 60' with the
ground. How fast is the altitude of the plane changing?
Answers
Answer:
The altitude is changing at a speed of 200 √3 km/hr
Step-by-step explanation:
Here, we want to know how far the altitude of the plane is changing
we are told that the airplane makes an angle of 60 degrees with the ground
So therefore , the rate of change of its altitude will be ;
sin 60 = x/ 400
x = 400 sin 60
x = 400 * √3/2
x = 200 √3 km/hr
The altitude is increasing at a rate of 346.61 km/hr.
The diagram below denotes the given scenario.
Then from the diagram we have,
[tex]sin60^{\circ}=\frac{y}{z}\\\frac{\sqrt{3}}{2} =\frac{y}{z}\\ y=\sqrt{3}\\z=2[/tex]
Then,
[tex]sin\theta =\frac{y}{z}\\cos\theta \frac{d\theta}{dt}\\=\frac{z\frac{dy}{dt}-y\frac{dz}{dt}}{z^2} \\\frac{dy}{dt}=\frac{z^2cos\theta\frac{d\theta}{dt+y\frac{dz}{dt}}}{z}\\\frac{dy}{dt} =\frac{2^2(cos60^{\circ})+\sqrt{3}(400)}{2}\\ \frac{dy}{dt}=346.41 km/hr[/tex]

Mia discovered that if she takes half her age and adds 3, it produces the same result as taking one-fourth of her age and adding 7. How old is Mia?
Answers
Answer:
she would be 16 years old
Step-by-step explanation:
hope this helps!! :D
From the given information we found out that age of Mia is 16 years.
What is a linear equation?A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Given, Mia discovered that if she takes half her age and adds 3,
Assuming Mia's age to be x years.
∴ (1/2)x + 3...(i)
It produces the same result as taking one-fourth of her age and adding 7,
∴ (1/4)x + 7...(ii)
So, (1/2)x + 3 = (1/4)x + 7.
(1/2)x - (1/4)x = 7 - 3.
(1/4)x = 4.
x = 4×4/1.
x = 16.
So, Age of Mia is 16 years.

Based on this model, approximately what was the increase in the population of Riverside at the end of 2009 compared to the end of 2006?
Answers
The correct format of the question is
At the end of 2006, the population of Riverside was 400 people. The population for this small town can be modeled by the equation below, where t represents the number of years since the end of 2006 and P represents the number of people. [tex]P = 400 ( 1.2 )^ t[/tex] Based on this model, approximately what was the increase in the population of Riverside at the end of 2009 compared to the end of 2006?
(A) 291
(B) 691
(C) 1040
(D) 1440
Answer:
The increase in the population at the end of 2009 is 291 people
Step-by-step explanation:
We are given the equation as [tex]P = 400 ( 1.2 )^ t[/tex]
where
P = No of People
t= No of Years
it is given that in the year 2006 the population is 400
this will only happen when we take t= 0
so for
Year value of t
2006- t = 0
2007- t = 1
2008- t = 2
2009 t = 3
No of people in 2009 will be
[tex]P = 400(1.2)^3[/tex]
= 400*1.728
P = 691.2
Since the equation represents no of people so it can't be in decimals, Therefore the population will be 691
Increase = P(2009) - P(2006)
= 691 - 400
= 291
The increase in the population at the end of 2009 is 291 people.
