How do you find the equation, domain, and range using a graph?
Answer/Step-by-step explanation:
For the one on the left, the domain is (-∞,-1)∪[0,0]∪(1,3]
Remember that the domain is what values x are. If the dot is solid, use a bracket, if it is empty, use parentheses.
The range is [-3,-3]∪[-1,-1]∪(2,4]
The equation is a piece-wise function.

Answer:
y = 1000·1.20^x
Step-by-step explanation:
The form of an exponential function is ...
y = a·b^x
where 'a' is the initial value (y-intercept), and 'b' is the common ratio (growth factor).
The growth factor is related to the growth rate by ...
growth factor = 1 + growth rate
For a growth rate of 20%, the growth factor is ...
growth factor = 1 +20% = 1.20
__
The problem statement tells you the initial value is $1000, so your exponential function is ...
y = 1000·1.20^x . . . . . x is the number of years after the current year; y is the watch value in dollars

Answer:
5x + 2y = 9
Step-by-step explanation:
Find the slope of the line that is perpendicular to 2x - 5y = 7 :
m= [tex]\frac{-5}{2}[/tex]
Find the y - intercept of the function:
b = [tex]\frac{9}{2}[/tex]
substitute m= [tex]\frac{-5}{2}[/tex] and b = [tex]\frac{9}{2}[/tex] into y = mx + b :
y = [tex]\frac{-5x}{2}[/tex] + [tex]\frac{9}{2}[/tex]

How do you find derivative of a function with two variables.
A function z=f(x,y) has two partial derivatives and y. These derivatives correspond to each of the independent variables and can be interpreted as instantaneous rates of change (that is, as slopes of a tangent line). Similarly, ∂z/∂y represents the slope of the tangent line parallel to the y-axis.

Answer: QE = 10
Step-by-step explanation: To solve this problem, it's important to understand that the diagonals of a parallelogram bisect each other.
This means that E is the midpoint of diagonal SQ.
So we can setup the equation x² + 9x = 4x + 6.
To solve this polynomial equation, set it equal to zero first.
So we have x² + 5x - 6 = 0 and we get (x + 6)(x - 1) = 0
when we factor the left side of the equation.
So this means that x = -6 or x = 1.
However, -6 will give us a negative length when we plug it in
to find QE so this will not work.
However, plugging 1 in will give us 10 as a length so QE = 10.
Which relationships describe angles 1 and 2?
Select each correct answer.
complementary angles
adjacent angles
supplementary angles
vertical angles
Answer: Supplementary angles
Step-by-step explanation:
Bye have a nice day.
Answer:
does this help answer your question? Answer: They are supplementary angles, because angle 1 + angle 2 = 180° , i.e. they form a line.
Step-by-step explanation:
I would suggest that you memorize these -
1. Complementary angles always =90°
For example, 30 degrees and 60 degrees are complementary angles.
2. Adjacent angles are two angles that have a common side and a common vertex (corner point) but do not overlap in any way. (share a side)
3. Supplementary angles are those that in sum give 180°.
4. Vertical angels ---- each of the pairs of opposite angles made by two intersecting lines.
So, what have you learned? You learned that complementary angles are two angles that add up to 90 degrees, supplementary angles are two angles that add up to 180 degrees, vertical angles are opposite angles at an intersection of two straight lines, and adjacent angles are two angles that are next to each other.

Explain why 82.5 + 8(0.25x) = 338.5 is equivalent to 82.5 + 2x = 338.5
Answer:
Multiply 0.25x by 8
Step-by-step explanation:
82.5 + 8(0.25x) = 338.5
Multiply 0.25x by 8 we get,
8 × 0.25x = 2x
Thus, 82.5 + 2x = 338.5
-TheUnknownScientist 72
Commutative property states out that in multiplication, changing the order of the numbers still have the same product (the product remains the same)
So, we can rewrite 8(0.25x) as (8 x 0.25)x = 2x
So, 82.5 + 8(0.25x) = 82.5 + 2x
Two different cars each depreciate to 60% of their respective original values. The first car depreciates at an annual rate of 10%. The second car depreciates at an annual rate of 15%. What is the approximate difference in the ages of the two cars? 1. 7 years 2. 0 years 3. 1 years 5. 0 years.
The approximate difference in the ages of the two cars, which depreciate to 60% of their respective original values, is 1.7 years.
Depreciation is to decrease in the value of a product in a period of time. This can be given as,
[tex]FV=P\left(1-\dfrac{r}{100}\right)^n[/tex]
Here, (P) is the price of the product, (r) is the rate of annual depreciation and (n) is the number of years.
Two different cars each depreciate to 60% of their respective original values. The first car depreciates at an annual rate of 10%.
Suppose the original price of the first car is x dollars. Thus, the depreciation price of the car is 0.6x. Let the number of year is [tex]n_1[/tex]. Thus, by the above formula for the first car,
[tex]0.6x=x\left(1-\dfrac{10}{100}\right)^{n_1}\\0.6=(1-0.1)^{n_1}\\0.6=(0.9)^{n_1}[/tex]
Take log both the sides as,
[tex]\log 0.6=\log (0.9)^{n_1}\\\log 0.6={n_1}\log (0.9)\\n_1=\dfrac{\log 0.6}{\log 0.9}\\n_1\approx4.85[/tex]
Now, the second car depreciates at an annual rate of 15%. Suppose the original price of the second car is y dollars.
Thus, the depreciation price of the car is 0.6y. Let the number of year is [tex]n_2[/tex]. Thus, by the above formula for the second car,
[tex]0.6y=y\left(1-\dfrac{15}{100}\right)^{n_2}\\0.6=(1-0.15)^{n_2}\\0.6=(0.85)^{n_2}[/tex]
Take log both the sides as,
[tex]\log 0.6=\log (0.85)^{n_2}\\\log 0.6={n_2}\log (0.85)\\n_2=\dfrac{\log 0.6}{\log 0.85}\\n_2\approx3.14[/tex]
The difference in the ages of the two cars is,
[tex]d=4.85-3.14\\d=1.71\rm years[/tex]
Thus, the approximate difference in the ages of the two cars, which depreciate to 60% of their respective original values, is 1.7 years.

Answer:

Polygon ABCDE is composed entirely of straight-line segments with lengths and right angles as indicated. Line segment AB is parallel to line segment EC (not shown). Compute the length of line segment AB
It should be noted that a polygon is a flat two dimensional closed shape that has straight sides.
What is a polygon?Your information is incomplete. Therefore, an overview of a polygon will be given.
A polygon simply means a plane figure which is described by a finite number of straight line segments that are connected in order to form a closed polygonal chain.
In this case, the length of a line segment can be measured by simply measuring the distance between the two endpoints.
It's simply the path between two points that has a definite length that can be measured.
Examples of polygon include triangles, quadrilateral, pentagon, etc.
