What is the equation of
y=x3
with the given transformations?
vertical stretch by a factor of 3, horizontal shift 4 units to the right, vertical shift 3 units down
Answer:
The parent function is y = x³.
After a vertical stretch by a factor of 3, obtain
y = 3x³
After a horizontal shift 4 unit to the right, obtain
y = 3(x - 4)³
After a vertical shift 3 units down, obtain
y = 3(x - 4)³ - 3
Answer: y = 3(x - 4)³ - 3
y = 3(x - 4)³ - 3 is the equation of y=x³ with the given transformations
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph.
The given equation is y=x³
A translation of a graph is its rigid movement, vertically or horizontally.
From given we have,
There is a vertical stretch of 3 units, hence the function is multiplied by 3.
There is a horizontal shift of 4 units to the right, hence x -> x - 4.
There is a vertical shift of 3 units down, hence 3 is subtracted from the function.
The required equation is given by y = 3(x - 4)³ - 3.
Hence y = 3(x - 4)³ - 3 is the equation of y=x³ with the given transformations

Im not exactly sure what to do, could someone help me out?
Answer:
AB = 18 in.
BC = 22 in.
ED = 33 in.
Angle B = not possible
Angle C: not possible
Angle D = 39°
Angle E: not possible
Angle F: not possible
Step-by-step explanation:
Because it is given that ΔABC≅ΔDFE, we can find the corresponding sides and angles and then find all possible missing side and angle measures from the given diagram.
AB corresponds to DF (ΔABC ≅ ΔDFE)
Because DF = 18, then AB must equal 18.
BC corresponds to FE (ΔABC≅ΔDFE)
Because FE = 22, then BC must equal 22.
ED corresponds to CA (ΔABC≅ΔDFE)
Because CA = 33, then ED must equal 33.
Angle D corresponds to angle A (ΔABC≅ΔDFE)
Because angle A = 39°, then angle D must equal 39°.
All other angles cannot be found since they are not given on the corresponding angles of the triangles in the diagram.
I hope this helps you :)
-2 (-3x + 3) + 2x = 58
Answer:
x = 8
Step-by-step explanation:
Given
- 2(- 3x + 3) + 2x = 58 ← distribute and simplify left side
6x - 6 + 2x = 58
8x - 6 = 58 ( add 6 to both sides )
8x = 64 ( divide both sides by 8 )
x = 8

If g(x) = 3x² – 2x–5, what is the
value of g(-1) ?
Answer:
0
Step-by-step explanation:
g(-1)=3×(-1)²-2×(-1)-5 g(-1)=3×1+2-5 g(-1)=3+2-5 g(-1)=5-5 g(-1)=0 ......
The value of g(x) = 3x² - 2x - 5, at x = -1 is g(-1) and it is equal to zero.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, A function g(x) = 3x² - 2x - 5.
Now, The value of g(-1) is the same as x = - 1 in g(x).
Therefore, g(-1) = 3(-1)² - 2(-1) - 5.
g(-1) = 3 + 2 - 5.
g(-1) = 0.

Answer:
Note. There is a mismatch between the graph and the equation
------------------------------
As per the graph, 6 ft is reached at 4 secondsThe graphed line is f = 1.5s------------------------------
If we go by the equation, then:

Henry places x marbles into an empty bucket.Each marble has the same weight. The weight, in ounces, of the bucket and marbles can be calculated using the expression shown
Complete Question:
Henry places x marbles into an empty bucket. Each marble has the same weight. The weight, in ounces, of the bucket and marbles can be calculated using the expression shown: 3x + 8
What does the term 8 represent in this expression?
Answer:
The weight of the bucket
Step-by-step explanation:
Given
[tex]Weight = 3x + 8[/tex]
Required
What does 8 represent?
The given expression illustrates the weight of the whole system i.e. bucket and marbles
i.e.
[tex]Weight = Weight\ of\ x\ marble + Weight\ of\ Bucket[/tex]
Since there are x marbles, by comparison:
[tex]Weight\ of\ x\ marble = 3x[/tex]
[tex]Weight\ of\ bucket = 8[/tex]
Hence, 8 represents the weight of the bucket

If y= 5x-2 and x= 4b+3 then y is equivalent to which of the following
Answer:
y = 20b + 13
Step-by-step explanation:
From the above, we want to get y
Using the given d value, we simply proceed to substitute
y = 5x-2
x = 4b + 3
Substituting x-values, we have
y = 5(4b + 3)-2
y = 20b + 15-2
y = 20b + 13

Need explanation for how to find "E"(in the picture attached), and how to calculate "sin".
Answer:
Step-by-step explanation:
E is just that Vertex/Angle.
[tex]sin[/tex] is a measure of an angle.
You should learn SOHCAHTOA
[tex]sin = opposite/hypotenuse\\cos(ine) = adjacent/hypotenuse\\tan(gent)=opposite/adjacent[/tex]
The opposite side is relative to the angle.
In this case, the opposite of E is 20
The hypotenuse is 29
