Given:
The function is
[tex]d(x)=850(0.94)^x[/tex]
To find:
The domain of the function.
Solution:
Domain is the set of input values.
We have,
[tex]d(x)=850(0.94)^x[/tex]
It is an exponential function, with initial value 850 and decay factor 0.94 because 0.94<1.
The exponential functions are defined for all real values of x. So, the domain of exponential function is always the set of all real numbers.
Therefore, the domain of the function d(x) is the set of all real numbers, i.e., R.
Find the slope and y-intercept. Pleasee
Answer:
slope: -2
y-intercept: 6
Step-by-step explanation:
Answer:
[tex]slope=-2\\\\y-intercept=6[/tex]
Step-by-step explanation:
The slope is the change in the y-axis over the change in the x-axis. To find the slope, you need to move vertically from a given point. Once you are horizontal to another point, move over to it. Count the spaces between each:
Start at (0,6)Move down to (0,4). Since you moved down two spaces, use the value -2 to define the riseMove to the right to point (1,4). Since you moved to the right 1 space, use the value 1 to define the run.Insert the values into [tex]\frac{rise}{run}[/tex] → [tex]\frac{-2}{1}[/tex]Simplify → [tex]-2[/tex]Therefore, the slope is -2.
The y-intercept is where [tex]x=0[/tex] and where the line crosses over the y-axis. The coordinate point where this happens is [tex](0,6)[/tex], so the y-intercept is 6.

Can someone help me with this??
Answer:
see explanation
Step-by-step explanation:
The domain D are the values of x, that is
D = { 3, 6, 12, 18 }
The range R are the values of y , that is
R = { 5, 7, 9, 10 }
The relationship is a function if each value of x in the domain maps to exactly one unique value of y in the range.
The relation is not a function as
6 → 5 and 6 → 10 ( that is 2 different values )

f(x) = |x|
g(x) = |x+9| - 5
We can think of g as a translated (shifted) version of f.
Complete the description of the transformation.
Use nonnegative numbers.
The transformed function g(x) = |x + 9| - 5 has a vertex at (- 9, - 5).
What is an absolute value function?We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.
In piecewise terms | x | = x for x ≥ 0 and | x | = - x for x < 0.
Given, The parent function is f(x) = |x|.
Now, The transformed function g(x) = |x + 9| - 5 is shifted x + 9 = 0 ⇒ x = - 9 units along the x-axis and - 5 units along the y-axis.
The vertex of the modulus function is at (- 9, - 5).

Please answer fast, it's important... Q) find the volume of cube whose dimensions are (x+7y), (7x-y) and (xy-5).
Answer:
[tex]Volume = 7x^3y+48x^2y^2-7xy^3 -35x^2-240xy-35y^2[/tex]
Step-by-step explanation:
Given
Shape: Cube
Dimension: (x+7y), (7x-y) and (xy-5).
Required
Determine the volume
The volume is calculated by multiplying the dimensions:
[tex]Volume = (x+7y) * (7x-y) * (xy-5)[/tex]
Evaluate the first 2 brackets
[tex]Volume = [x(7x-y)+7y(7x-y)] * (xy-5)[/tex]

How many factors of 2020 have more than 3 factors? (As an example, 12 has 6 factors, namely 1, 2, 3, 4, 6, and 12.)
Answer:
[tex]10, 20, 202, 404, 505[/tex] and [tex]1010[/tex] has more than [tex]3[/tex] factors.
Step-by-step explanation:
Given: A number [tex]2020[/tex]

Below are two parallel lines with a third line intersecting them
X=|____|°
Answer:
x = 80°
Step-by-step explanation:
From the picture attached,
Two lines are parallel and third line (transversal) is intersecting these lines at two different points.
m(∠x) = 80° [Exterior alternate angles are equal in measure]
Therefore, x° = 80° is the answer.

Step-by-step explanation:
If triangles are similar then they have a scale factor. That is the factor that is being multiplied to each of the sides to create a new set of sides.
We need to find the scale factor between Triangle ABC and Triangle DEF.
We can use Sides AC and DF to determine the scale factor.
It would be 27/9 = 3
So all the sides in triangle DEF are 3 times the length of those in triangle ABC
this means that the side with x cm is just 3 × 5 which is 15 cm.

If you know the area of a circle, how can you find its radius? Use the drop-down menus to explain your answer.
Answer:
down below
Step-by-step explanation:
the area of a circle is pi times radius times radius
in order to find the radius of a circle when you know the area, you need to do the area divided by 3.14. after you have done that, divide that number by 2
please give me brainliest!!
Answer:
Working backward
Step-by-step explanation:
Formula: A = πr²
All you have to do is work backwardly
If you have the area, replace the "A" with the area.
You can replace the π with "3.14"
Then divide the area by "3.14"
Then when you get your answer, divide your answer that you got by its square root --> √
Then when you do that....you get your radius....and from there on, you can check it by substituting.

2/12 can be simplified to 1/6
Answer:
[tex]\frac{1}{6}[/tex]
Step-by-step explanation:
If there are 12 pages in a book, then there are 12 possible outcomes when one opens up a book. There are only two possibilities when a person opens up either 9 or 11. Probability is;
[tex]\frac{wanted-outcomes}{total-outcomes}[/tex]
Wanted-comes = 2
total-outcomes = 12
[tex]\frac{2}{12}\\\\=\frac{1}{6}[/tex]

>) Jamal can run 1 mile in 5.05 minutes.
If Jamal maintains this pace during
a 5-kilometer (5K) race, he expects
to break the course record of
15.25 minutes. Is Jamal's expectation
reasonable? Explain.
Answer:
Yes, his expectation is reasonable
Step-by-step explanation:
Mathematically;
1 mile = 1.609344 km
If he runs this in 5 minutes;
his speed will be 1.609344/5 = 0.3219 km/m
Now he intends breaking the record of 5 kilometers in 15.25 minutes
Distance = speed * time
What we shall have in this case will be;
15.25 * 0.3219 = 4.908
Approximately this is 5 km
So we can conclude that he will break the record if he runs at this speed

Answer:
B) Vertically stretched by a factor of 3, shifted to the right by 1 unit, and shifted up 2 units.
Step-by-step explanation:
The basic transformations of a rational function as shown here can be modeled by:
[tex]f(x) = \frac{a}{b(x - h)} + k[/tex]
a = vertical stretch / compression.
b = horizontal stretch / compression.
h = horizontal shift.
k = vertical shift.
If there is a negative sign by a, then it is a vertical reflection.
If there is a negative sign by b, then it is a horizontal reflection.
_____________
As seen here, the transformations of
[tex]f(x) = 2 + \frac{3}{x–1} [/tex]
There is no b value because x - 1 is completely factored or it can just be thought of as 1. a or the vertical stretch is a factor of 3 because that is the numerator of the rational expression. There is a horizontal shift of 1 unit to the right because when x is subtracted by 1 in the rational expression, the root of x - 1 by itself is 1 greater than x. Lastly, there is a vertical shift up 2 units because that means all the values of the function will increase by 2 units which moves the whole function up 2.
