An arithmetic sequence is represented by the explicit formula A(n) = 8 - 6(n - 1) What is the recursive formula? Group of answer choices
Answer:
A(1) = -4A(n) = A(n - 1) - 6Step-by-step explanation:
GivenAP with the explicit formula A(n) = 8 - 6(n - 1)To find Recursive formulaSolutionRecursive formula is the formula A(n) = A(n - 1) + d
Based on the explicit formula we have:
A(n) = 8 - 6(n - 1) = 8 - 6n + 6 = 2 - 6nA(n - 1) = 2 - 6( n - 1) = 2 - 6n + 6 = 8 - 6nThe common difference is:
d = A(n) - A(n - 1) = 2 - 6n - (8 - 6n) = 2 - 6n - 8 + 6n = - 6The first term is:
A(1) = 2 - 6(1) = 2 - 6 = -4So the recursive formula is:
A(1) = -4A(n) = A(n - 1) - 6For a soccer practice, the coach set up four cones, labeled W, X, Y, and Z, to mark the edges of the rectangular field. Suppose the field is drawn on a coordinate plane, where the x- and y-values represent the position, in yards, from the center of the field, which is located at (0, 0). The location of the cones are as follows. Cone W is located at (-38, -53). Cone X is located at (-38, 53). Cone Y is located at (38, 53). Cone Z is located at (38, -53). What is the perimeter of the field? A. 364 yards B. 8,056 yards C. 182 yards D. 38 yards
Answer:
A. 364 yards
Step-by-step explanation:
The distance between two points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)[/tex] on the coordinate plane is given as:
[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The cone W, X, Y and Z form a rectangle.
The perimeter for the rectangle = 2(length + breadth)
[tex]Length=|WX|=\sqrt{(-38-(-38))^2+(53-(-53))^2}=106 \\\\Breadth=|XY|=\sqrt{(38-(-38))^2+(53-53)^2}=76[/tex]
Perimeter = 2(length + breadth) = 2(106 + 76) = 364 yards

Write an exponential function to model the situation. Then find the value of the function after 5 years to the nearest whole number. A populaton of 330 animals that decreases at an annual rate of 22%.
Answer:
Results are below.
Step-by-step explanation:
First, we need to establish the decrease function in the given population:
FV= PV/(1+g)^n
FV= future value
PV= present value
g= decrease rate
n= number of periods
Now, for the given information:
PV= 330
g= 22% = 0.22
n= 5 years
FV= 330 / (1.22)^5
FV= 122

What is the area of a quadrilateral with vertices at (1,6),(7,6),(1,12),(7,12)?
Answer:
Let us consider the quadrilateral ABCD shown below.
Let us consider the quadrilateral ABCD shown below.

In the above quadrilateral, A(x1, y1), B(x2, y2), C(x3, y3) and D(x4, y4) are the vertices.
To find area of the quadrilateral ABCD, now we have take the vertices A(x1, y1), B(x2, y2), C(x3, y3) and D(x4, y4) of the quadrilateral ABCD in order (counter clockwise direction) and write them column-wise as shown below.

Add the diagonal products x1y2, x2y3, x3y4 and x4y1 are shown in the dark arrows.
(x1y2 + x2y3 + x3y4 + x4y1) -----(1)
Add the diagonal products x2y1, x3y2, x4y3 and x1y4 are shown in the dotted arrows.
(x2y1 + x3y2 + x4y3 + x1y4) -----(2)
Subtract (2) from (1) and multiply the difference by 1/2 to get area of the quadrilateral ABCD.
So, area of the quadrilateral ABCD is
= (1/2) ⋅ {(x1y2 + x2y3 + x3y4 + x4y1)
- (x2y1 + x3y2 + x4y3 + x1y4)}
Problem :
Find the area of the quadrilateral whose vertices are
(-4, -2), (-3, -5), (3, -2) and (2, 3)
Solution :
Let A(-4, -2), B(-3, -5), C(3, -2) and (2, 3).
Plot A, B, C and D in a rough diagram and take them in counter-clockwise order.

Then,
(x1, y1) = (-4, -2)
(x2, y2) = (-3, -5)
(x3, y3) = (3, -2)
(x4, y4) = (2, 3)
Area of triangle ABC is
= (1/2) ⋅ {(x1y2 + x2y3 + x3y4 + x4y1)
- (x2y1 + x3y2 + x4y3 + x1y4)}
= (1/2) x {[20 + 6 + 9 - 4] - [6 - 15 - 4 - 12]}
= (1/2) x {[31] - [-25]}
= (1/2) x {31 + 25}
= (1/2) x 56
= 28
So, area of the given quadrilateral is 28 square units.

The linear relation is y = 0.049x + 8.606 then the value of y is 83. Then the correct option is H.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
The linear relation is given as
[tex]\rm y - 63 = \dfrac{63-60}{1106-1045} (x - 1106)\\\\y = 0.049x+8.606[/tex]
For x = 1500, then the value of y will be
[tex]\rm y = 0.049\times 1500+8.606\\\\y = 82.37 \approx 83[/tex]

Step-by-step explanation:
Use the graph to write a linear function that relates y to x .
Answer:
2y = x + 2
Step-by-step explanation:
Looking at the graph, we can see from one point to the next (from right to left), the x-value rises by 2 and the y-value by 1;
From this we can work out the gradient between two points using the formula, i.e. the change/difference in y divided by the change/difference in x:
[tex]m = \frac{dy}{dx} = \frac{1}{2}[/tex]
Joining the points gives a straight line, which means a constant gradient of ¹/₂
Use the line equation formula to get the function:
y - y₁ = m(x - x₁)
m = ¹/₂
x₁ = 0
y₁ = 1
y - 1 = ¹/₂.(x - 0)
y - 1 = ¹/₂.x
2y - 2 = x
2y = x + 2
