Determine the simple interest. The rate is an annual rate. Assume 360 days in a year. p = $502.45,r=5.3%,t = 53days The simple interest is $ (Do not round until the final answer. Then round to the nearest cent as needed.)
Answers
r = R/100 = 5.3%/100 = 0.053 per year.
Putting time into years for simplicity,
53 days / 360 days/year = 0.147222 years.
Solving our equation:
A = 502.45(1 + (0.053 × 0.147222)) = 506.3704997767
A = $506.37
The total amount accrued, principal plus interest, from simple interest on a principal of $502.45 at a rate of 5.3% per year for 0.147222 years (53 days) is $506.37.

Answers
Answer:
[tex]\huge\boxed{\sf x = 14 , y = 10}[/tex]
Step-by-step explanation:
Let the two numbers be x and y
Condition # 1:
x + y = 24 ---------------------(1)Condition # 2:
x = 2y - 6 ----------------------(2)[tex]\rule[225]{225}{2}[/tex]
Putting Equation # 2 in Equation # 1
2y - 6 + y = 24
3y - 6 = 24
Adding 6 to both sides
3y = 24 + 6
3y = 30
Dividing both sides by 3
y = 10
[tex]\rule[225]{225}{2}[/tex]
Putting y = 10 in Equation # 2
x = 2y - 6
x = 2(10) - 6
x = 20 - 6
x = 14
[tex]\rule[225]{225}{2}[/tex]
The two numbers are 10 and 14.
The sum of 2 numbers is 24.
let the number be x and y . Therefore,
x + y = 24
One is 6 less than twice the other. therefore,
2x - y = 6
Combine the equations
x + y = 24
2x - y = 6
3x = 30
x = 30 / 3
x = 10
x + y = 24
10 + y = 24
y = 24 - 10
y = 14
The 2 numbers are 10 and 14 .

Review the graphs of f(x) = –x5 + 2x4 + 1 and g(x), which is a translation of f(x).
On a coordinate plane, g (x) curves down through (negative 3, 3) to (negative 2, 1) and then curves up to (negative 0.5, 3.8). It then curves down through (0, 0) into quadrant 4. y = f (x) curves down through (negative 1, 3) to (0, 1) and then curves up to (1.5, 3.8). It then curves down through (2, 0).
How can g(x) be expressed in terms of f(x)?
g(x) = (–x5 + 2x4 + 1) + 2
g(x) = –(x + 2)5 + 2(x + 2)4 + 1
g(x) = (–x5 + 2x4 + 1) – 2
g(x) = –(x – 2)5 + 2(x – 2)4 + 1
Answers
Answer:
choice B
g(x) = –(x + 2)5 + 2(x + 2)4 + 1
The function g(x) can be represented in terms of f(x) like this:
g(x) = -(x - 2)⁵ +2(x - 2)⁴ + 1.
Hence, 4th option is the right choice.
What does it mean to translate a graph?The translation is the process of moving a graph horizontally or vertically. To put it another way, each point on the parent graph is translated to the left, right, up, or down, to get the translated graph.
How do we solve the given question?We know that g(x) is a transformation of f(x) = -x⁵ + 2x⁴ + 1.
Since, g(x) is the transformation of f(x) we try to find the relation between the points on f(x) and g(x).
Let the point on f(x) be (x₁, y₁) and that on g(x) be (x₂, y₂).
f(x) passes through the points (-1, 3), (0,1), (1.5, 3.8), and (2, 0).
Corresponding points on g(x) are (-3, 3), (-2, 1), (-0.5, 3.8), and (0, 0).
We can see that the y-coordinate is the same for corresponding points. So, y₂ = y₁.
For the x-coordinate, we see that for every corresponding point on g(x), it is 2 less than the point on f(x). So, x₂ = x₁ - 2.
Now, in the function f(x), we have x = x₁. So to find the function g(x), we substitute the value of x₂ = x₁ - 2 = x - 2 in f(x) to get the equation of g(x).
∴ g(x) = f(x-2)
or, g(x) = -(x - 2)⁵ +2(x - 2)⁴ + 1.
∴ The function g(x) can be represented in terms of f(x) like this:
g(x) = -(x - 2)⁵ +2(x - 2)⁴ + 1.
Hence, 4th option is the right choice.

Help me plz ASAP explain why
Answers
Answer:
a. -2
b. 3
c. 3
d. -3
e. x=-2
Step-by-step explanation:
When a question asks for f(x), it is basically just asking for what the y-value is at the given point of x. So for example, to solve the first one: f(-4), we see that the x-value is -4. This means it is asking for the y-value at x=-4. As we can see from the graph, where x = -4, the y-value is -2 (along the bottom flat line) therefore f(-4) = -2.
This is the same for the other three, f(0) = 3 because the line at x=0 is crossing at y=3. etc.
Finally e is difference because it is instead asking for the x-value when y=6. To solve this we just need to find a point on the graph where the line is at y=6. This, as we can see is at the top of the highest point and occurs where x=-2.

20 POINTS!!!!! A cartographer is making a city map. Line m represents Murphy Street. The cartographer translates points on line m along the vector angleleft1, −3angleright to draw Nolan Street. Draw the line for Nolan Street on the coordinate plane and complete its equation. What is the image of (0, 3) in this situation?
Answers
Answer:
[tex]y=2x-2[/tex] and image of (0,3) is (1,0).
Step-by-step explanation:
From the given graph it is clear that the line of Nolan Street passes through the points (0,-2) and (1,0).
So, the equation of Nolan Street is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-(-2)=\dfrac{0-(-2)}{1-0}(x-0)[/tex]
[tex]y+2=2x[/tex]
[tex]y=2x-2[/tex]
So, the equation of the Nolan Street is [tex]y=2x-2[/tex].
It is given that the cartographer translates points on line m along the vector <1, −3> to draw Nolan Street. So, the rule of translation is
[tex](x,y)\to (x+1,y-3)[/tex]
The image of (0, 3) in this situation.
[tex](0,3)\to (0+1,3-3)=(1,0)[/tex]
The image of (0,3) is (1,0).

If A=[xy5−8] determine the values of x and y for which A2=A.
Answers
Answer:
x = 9, y = -72/5Step-by-step explanation:
Given the 2 by 2 matrix [tex]A = \left[\begin{array}{-cc}x&5\\y&-8\\\end{array}\right][/tex] , we are to find the value of x and y for the expression A² = A to be true.
First we need to find A² by multiplying the same matrix together
[tex]A^2 = \left[\begin{array}{-cc}x&5\\y&-8\\\end{array}\right] \left[\begin{array}{-cc}x&5\\y&-8\\\end{array}\right]\\\\ \ we \ normally \ multiply \ the \ rows \ of \ the \ first \ matrix \ with \ the \ column \ of \ the \ second \\\\A^2 = \left[\begin{array}{-cc}x^2+5y&5x-40\\xy-8y&5y+64\\\end{array}\right]\\\\Since \ A^2 = A,\ hence;\\\\\left[\begin{array}{-cc}x^2+5y&5x-40\\xy-8y&5y+64\\\end{array}\right] = \left[\begin{array}{-cc}x&5\\y&-8\\\end{array}\right]\\[/tex]
Equating the first row and second column of both matrices together, we will have;
5x-40 = 5
add 40 to both sides of the equation
5x-40+40 = 5+40
5x = 45
x = 45/5
x = 9
Similarly, we will equate the second row and second column of both matrices to have;
5y+64 = -8
Subtract 64 from both sdies
5y+64-64 = -8-64
5y = -72
y = -72/5
Hence the value of x is 9 and y is -72/5
Matrices are used to represent data in rows and columns
The values of x and y are 9 and -14.4 respectively.
Matrix A is represented as:
[tex]\mathbf{A = \left[\begin{array}{ccc}x&5\\y&-8\end{array}\right] }[/tex]
Calculate [tex]\mathbf{A^2}[/tex]
[tex]\mathbf{A^2 = \left[\begin{array}{ccc}x&5\\y&-8\end{array}\right] \times \left[\begin{array}{ccc}x&5\\y&-8\end{array}\right] }[/tex]
Recall that [tex]\mathbf{A^2 = A}[/tex]
This means that:
[tex]\mathbf{\left[\begin{array}{ccc}x^2++5y&5x-40\\xy-8y&5y+64\end{array}\right] = \left[\begin{array}{ccc}x&5\\y&-8\end{array}\right] }[/tex]
So, by comparison
[tex]\mathbf{5x - 40 = 5}[/tex]
[tex]\mathbf{5x = 40 + 5}[/tex]
[tex]\mathbf{5x = 45}[/tex]
[tex]\mathbf{x = 9}[/tex]
Similarly
[tex]\mathbf{5y + 64 = -8}[/tex]
[tex]\mathbf{5y =-64 -8}[/tex]
[tex]\mathbf{5y =-72}[/tex]
[tex]\mathbf{y =-14.4}[/tex]
Hence, the values of x and y are 9 and -14.4 respectively.
