An investment is a dedication of an asset to achieve an increase in value over a period of time. Investing requires the sacrifice of current assets such as time, money and effort. In finance, the purpose of an investment is to generate a profit on the invested asset
The most common example of an investment type. Investment is generally what you want to use in the future with the aim of generating regular cash flow or increasing the value of something over time so that you can sell it at a higher price than you purchased.

What is m/3= -1.5 what is m???
Answer:
-4.5
Step-by-step explanation:
M would be -4.5 because if you multiply -1.5 by 3 you get -4.5. Therefore the equation would be -4.5/3= -1.5 .

1. 3.6, 10.8
2. 6.9, 3.2
3. 6, 4
I’m sorry for spam but I really need help
Only answer is you know the answer plz!
Answer:Triangle Inequality Theorem
The Triangle Inequality theorem states that
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
The Converse of the Triangle Inequality theorem states that
It is not possible to construct a triangle from three line segments if any of them is longer than the sum of the other two.
The length of s is greater than 3 and less than 11
Step-by-step explanation:
Jaden is saving money to buy a bike that costs $290. He has saved $140 so far. He plans on saving $25 each week. Write and solve an equation to determine in how many weeks (identify the question) Jaden will have enough money to buy the bike.
What does the variable in question 4a represent?
Answer:
25w+140=290
He will have enough money in 6 weeks
w represents the amount of weeks
Step-by-step explanation:
25w+140=290
$25 every week + the original $140 = the total needed $290
Answer:
140 + 25w = 290
w = 6
Step-by-step explanation:
Goal: $290
Currently have $140
Saving $25 each week (variable)
Start with your given amounts :
(base) 140 + 25w (variable solving for) = 290 (goal you want equation to equal)
w stands for the amount of weeks for the goal to be reached
Solve:
140 + 25w = 290
subtract 140
25w = 150
divide 25
w=6
Double check (optional but suggested)
140 + 25 (6) = 290
140 + 150 = 290
290 = 290
correct

Answer:
x = 2
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relations between trig functions and angle.
Tan = Opposite/Adjacent
tan(θ) = y/x
Sin = Opposite/Hypotenuse
sin(θ) = y/4
The given relation is ...
tan(θ) = 2·sin(θ)
y/x = 2(y/4)
2 = x . . . . . . . multiply by (2x/y)
_____
Additional comment
Then the angle can be found from the relation ...
Cos = Adjacent/Hypotenuse
cos(θ) = x/4 = 2/4 = 1/2
θ = arccos(1/2) = 60°
and the value of y is ...
y = 4·sin(60°) = 2√3

In this figure, angles R and S are complementary. Find the measure of angle S.
S
62°
R
PLEASE HELP ASAP
Answer:
Angle S is 28 degrees.
Step-by-step explanation:
You know angle R is 62 degrees and that angle Q is 90 degrees because the angle is marked by a teeny square (as I like to call it). You ten can add these two angles together and you will get the angle of 152 degrees. And as you should know that all angles of a triangle added together are 180 degrees you just take 180 degrees and subtract it with the two known angles added together. Thus you know that the final answer to S is 28 degrees.

4x=-20 solve for x show your work
Answer: x = 5
Step-by-step explanation:
Answer:
x = -5
Step-by-step explanation:
We have the expression 4x = -20 and are asked to solve x.
To solve, we need to isolate x.
4x = -20
Divide 4 :
x = -5
To solve this equation we must first -
2x - 4= 10
O subtract 4 from both sides
O add 4 to both sides

Quadrilateral ABCD is a rectangle. The measure of angle CBE is equal to 32°, find the
measure of angle BEC.
Answer:
116 degrees
Step-by-step explanation:
well from the picture we know this is a 45 45 90 style triangle therefore in if CBE is equal to 32 then ECB should also be equal to 32 leaving you with a total number of 64 degrees within the triangle. and in every triangle you must add up the degrees to 180 so if we subtract 64 from 180 we get 116 degrees for BEC
Answer: 116
Step-by-step explanation:
32 + 32 (because the angles are complementary) + 116 = 180!

A random sample of 1000 people who signed a card saying they intend to quit smoking were contacted 9 months later. Turned out that 210 (21%) of the sampled individuals had not smoked in the past 6 months. What is the population, parameter, sample and statistic?
Answer:
Population is the total number of people that fall into the description of those that the research concerns.
In this case, Population is: Everyone who signed a card saying that they intend to quit smoking.
Sample. This is a subset of the population that the research is based on.
Sample = 1,000 people surveyed.
Parameter and Statistic are both descriptive measures but parameter is for the population and statistic is for the sample.
Parameter = Percentage of total population who have not smoked in 6 months.
Statistic = 21% of sample who have not smoked in 3 months.

Answer:
x = -4, x = 4
Step-by-step explanation:
A denominator cannot equal zero since division by zero is undefined.
Set the denominator equal to zero and solve for x. That will give you the values of x that would cause the denominator to be equal to zero and must be excluded from the domain.
x^2 - 16 = 0
(x + 4)(x - 4) = 0
x + 4 = 0 or x - 4 = 0
x = -4 or x = 4
Answer: x = -4, x = 4

Answer:
The 3rd one
Step-by-step explanation:
Let find angle z
Using law of sines
[tex] \frac{xy}{ \sin(z) } = \frac{xz}{ \sin(y) } [/tex]
Plug in the numbers
[tex] \frac{43}{ \sin(x) } = \frac{40}{ \sin(68) } [/tex]
Flip both equations
[tex] \frac{ \sin(x) }{43} = \frac{ \sin(68) }{40} [/tex]
where z=85.4 or 94.6
Using the triangle interior sun theorem,
if z=85.4 let add up all so The first 2 are rules out angles to make sure they add up to 180.
[tex]if \: z = 85.4[/tex]
[tex]85.4 + 68 + x = 180[/tex]
[tex]x = 153.4[/tex]
[tex]x = 26.6[/tex]
The fourth one doesnt have 26.6 as a angle so it cant be that
Let try if z=94.6
[tex]68 + 94.6 + x = 180[/tex]
[tex]162.6 + x = 180[/tex]
[tex]x = 17.4[/tex]
The third one has that.
Also we reuse law of sines YZ=12.9 so it is the third one.
