Answer:
see below
Step-by-step explanation:
principal = $5,000
interest rate = 2.3%
account A: compound monthly for 10 years
account B: compound continuously for 10 years
account A: compound monthly for 10 years
A = P (1 + r/12)^ r*t
= $5,000 (1 + .023/12)^ 12(10)
= $6,291.6
account B: compound continuously for 10 years
FVn = PV * e^r*t
= $5,000 * e ⁽⁰ ⁰²³ˣ¹⁰⁾
= $6,293
Gregory may chose account B. (but the difference is only $1.40)
Gregory may choose account B.
Given that,
Principal = $5,000 .The interest rate = 2.3% .Account A: compound monthly for 10 years .Account B: compound continuously for 10 years
Based on the above information, the calculation is as follows:
For Account A[tex]A = P (1 + r\div 12)^ {r\times t} \\\\= $5,000 (1 + .023\div 12)^ {12(10)}[/tex]
= $6,291.6
For account B
[tex]FVn = PV \times e^{r\times t}\\\\ = $5,000 \times e^ {0.023\times 10}[/tex]
= $6,293
Therefore we can conclude that Gregory may choose account B.

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

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
so,

How do you divide mixed fractions
Answer:
See my explanation below.
Step-by-step explanation:
Let's start with two random mixed numbers.
[tex]4\frac{3}{5}[/tex] ÷ [tex]5\frac{1}{4}[/tex]
The first step is starting with [tex]4\frac{3}{5}[/tex]. Think about going from the denominator to the number on the left. After you remember that rule multiply 4 by 5. You should get 20. After that, you add by the numerator. 20 + 3=23
This is how it would be written.
[tex]\frac{23}{5}[/tex]
Do the same for the next mixed number. 5 x 4 = 20 and add by the numerator 21.
[tex]\frac{21}{4}[/tex]
After this is done. You will multiply by those fractions. [tex]\frac{23}{5}[/tex] x [tex]\frac{21}{4}[/tex] = [tex]\frac{483}{20}[/tex] we would write it as [tex]24\frac{3}{20}[/tex] as a mixed fraction.

ILL MARK U BRAINLIEST IF U DO THIS AND GET IT RIGHT
Answer:
Step-by-step explanation:
1.
The x's and y's will shift to the right and upward. This will make the shape larger because we are multiplying each point (x, y) by 2 [2(x, y)]. The new shape is similar since it is practically the same exact figure with a different scale. Furthermore, the angle measurements are congruent.
2. This will shift the x's and the y's upward and to the right making the shape larger although the shape will be stretched and will not be similar in terms of angle measures and other factors.
3. This will make the figure larger although the angle measurements will not be preserved and a new shape will form. This will not be similar from the original one since it will be stretched and the angles measurements are not congruent..

Solve the
9x+42=4x-13
The solution is x=
Answer:
x = -11
Step-by-step explanation:
9x+42=4x-13
(add 13 to both sides)
9x+55=4x
(subtract 9x from both sides)
55=-5x
(divide by -5)
-11 = x
You isolate the x term basically.
First you bring 4x from the right hand side to the left hand side and so the equation would be: 9x - 4x + 42 = -13
Then you bring 42 from the left hand side to the right hand side so the equation would look something like this: 9x - 4x = -13 - 42
Next subtract the x terms and the numbers on the right hand side too so you get: 5x = -55
Remove the coefficient from x and bring it to the right hand side with the operation as division. So you get: x = -55/5
Solve the division and you get: x = -11

Q3.
The length of a car is 3.6 metres.
Karl makes a scale model of the car.
He uses a scale of 1 cm to 30 cm.
Work out the length of the scale model of the car.
Give your answer in centimetres.
The length of the scale model of the car is 120 cm
Working out the length of the scale model of the car.From the question, we have the following parameters that can be used in our computation:
Length of a car = 3.6 meters
We have the scale to be
Scale = 1 cm to 30 cm
This means that
Scale = 1 cm : 30 cm
using the above as a guide, we have the following:
Scale : 3.6 meters = 1 cm : 30 cm
So we have
Scale = 3.6 m * 1 cm/30 cm
Evaluate
Scale = 0.12 m
Convert to cm
Scale = 120 cm
Hence, the length of the scale model of the car is 120 cm

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.
