The equation for the nth term of the given arithmetic sequence is an = -17 + 5(n - 1), which matches answer choice C.
The given sequence is an arithmetic sequence, where each term increases by a common difference. To find the equation for the nth term (an), you start with the first term (a1 = -17) and add the common difference (d = 5) multiplied by (n - 1), since the first term is already in place.
A correct formula for an arithmetic sequence is an = a1 + (n - 1)d. Applying this to the given sequence, we have an = -17 + (n - 1)5. Simplifying this expression gives us an = -17 + 5n - 5, which further simplifies to an = 5n - 22. Thus, the correct answer is an = -17 + 5(n - 1), which corresponds to answer choice C.

Find the perimeter of an isosceles trapezoid whose two bases have lengths of 10cm and 16 cm and a side length of 5cm
The perimeter of the isosceles trapezoid is 36cm.
Explanation:An isosceles trapezoid is a quadrilateral with two parallel sides of unequal length. To find the perimeter of an isosceles trapezoid, we need to add the lengths of all its sides. In this case, the two bases have lengths of 10cm and 16 cm, and one of the side lengths is 5cm. Since the two bases are parallel, the other side length is also 5cm.
The perimeter is calculated by adding the lengths of the bases and the two side lengths: 10cm + 16cm + 5cm + 5cm = 36cm.

The diagonals BF and CE divide the hexagon ABCDEF into two equilateral triangles and a square. Find the perimeter of the hexagon if BF = 3 cm. Answer: P = cm
Answer: The perimeter of the hexagon is 18 cm.
Step-by-step explanation: As given in the question, hexagon is shown in the attached figure.
The diagonals g and h divides the hexagon into two two equilateral triangles and one square .
Also, length of diagonal g = 3 cm.
We are to find the perimeter of hexagon.
We know that all the sides of a square are equal, so we have
length of b = length of h = length of e = length of g = 3 cm.
Since the two triangles are equilateral, so all their sides will be equal.
That is, length of a = length of f = length of g =length of c =length of d = length of h = 3 cm.
We know that the perimeter of a polygon is equal to the sum of the lengths of its sides.
Therefore, the perimeter of hexagon is given by
P = a + b + c + d + e + f = 3 + 3 + 3 + 3 + 3 + 3 = 18 cm.
Thus, the perimeter of the hexagon is 18 cm.

what is the rate of decay, as a percent, for the following function n(x)=7(0.067)^x
Answer: The rate of decay is 93.3%.
Step-by-step explanation:
Since we have given that
The exponential function is given by
[tex]n(x)=7(0.067)^x[/tex]
As we know the general equation of exponential function that is given by
[tex]n(x)=a(1-b)^x[/tex]
Here, a denotes the initial value
1-b denotes the rate of decay.
So, On comparing both the equations, we get that
[tex]1-b=0.067\\\\b=1-0.067\\\\b=0.933=0.933\times 100=93.3\%[/tex]
Hence, the rate of decay is 93.3%.

For what value of xis the square of the binomial 3x+1 is 9 times greater than the square of the binomial x–2?
Final answer:
The value of x for which the square of the binomial 3x+1 is 9 times greater than the square of the binomial x−2 is obtained by equating (3x + 1)² to 9(x − 2)², which simplifies and solves to x = 5/6.
Explanation:
To find the value of x for which the square of the binomial 3x+1 is 9 times greater than the square of the binomial x−2, we need to formulate and solve an equation based on the given conditions:
(3x + 1)² = 9(x − 2)²
Expanding both sides gives us:
9x² + 6x + 1 = 9x² − 36x + 36
Now, by simplifying and solving for x, we find:
42x = 35
x = 35 / 42
x = 5 / 6
Therefore, the value of x is 5/6.

Most sample surveys use random digit dialing equipment to call residential telephone numbers at random. the telephone polling firm zogby international reports that the probability that a call reaches a live person is 0.15. calls are independent. (a) a polling firm places 7 calls. what is the probability that none of them reaches a person?
The probability that none of the 7 calls reaches a person is approximately 0.1967.
Explanation:To find the probability that none of the 7 calls reaches a person, we need to calculate the probability that each individual call does not reach a person and then multiply those probabilities together.
The probability that a call reaches a live person is 0.15, so the probability that a call does not reach a live person is 1 - 0.15 = 0.85.
Therefore, the probability that none of the 7 calls reaches a person is 0.857 ≈ 0.1967.
Find an equation of the plane. the plane through the point (3, −8, −2) and parallel to the plane 9x − y − z = 7
Final answer:
The equation of the plane parallel to the given plane 9x - y - z = 7 and passing through the point (3, -8, -2) is 9x - y - z = 37.
Explanation:
The question involves finding an equation for a plane that is parallel to a given plane and passes through a specific point. Since the planes are parallel, they will have the same normal vector, and thus the same coefficients for x, y, and z. The given plane's equation is 9x - y - z = 7, so the normal vector is (9, -1, -1). Our plane must also have this normal vector, meaning our plane's equation will have the form 9x - y - z = D, where D is a constant we need to find such that the plane passes through the point (3, -8, -2).
Substituting this point into the equation gives us 9(3) - (-8) - (-2) = D, which simplifies to 27 + 8 + 2 = D. Therefore, D = 37 and the equation of our plane is 9x - y - z = 37.

a cube has a width of 20 ft what is the surface area of the cube
The surface area of the cube is 2,400 square feet.
To find the surface area of a cube, one must use the formula:
[tex]\[ \text{Surface Area} = 6 \times (\text{side length})^2 \][/tex]
Given that the width of the cube is 20 feet, we can assume that all sides of the cube are equal, since a cube has all sides of equal length. Therefore, the side length of the cube is 20 feet.
Now, we can substitute the side length into the formula:
[tex]\[ \text{Surface Area} = 6 \times (20 \text{ ft})^2 \] \[ \text{Surface Area} = 6 \times 400 \text{ ft}^2 \] \[ \text{Surface Area} = 2,400 \text{ ft}^2 \][/tex]
Thus, the surface area of the cube is 2,400 square feet.
the midpoint of PQ is R. R has coordinates (-3,2,-1) and P has coordinates (4,-6,-6). What are coordinates of Q?
The coordinates of point Q are (-10, 10, 4).
Explanation:To find the coordinates of point Q, we can use the midpoint formula. The midpoint formula states that the coordinates of the midpoint between two points P(x1, y1, z1) and Q(x2, y2, z2) are given by the average of the coordinates:
R = ((x1 + x2) / 2, (y1 + y2) / 2, (z1 + z2) / 2)
In this case, we are given that the midpoint R has coordinates (-3, 2, -1) and one of the points P has coordinates (4, -6, -6). Plugging in these values into the midpoint formula, we can solve for the coordinates of point Q:
Q = (2 * R - P)
Q = (2 * (-3, 2, -1) - (4, -6, -6))
Q = (-6, 4, -2) - (4, -6, -6)
Q = (-10, 10, 4)

If A ⊂ B, then A ∩ B = A ∪ B.
The statement "If [tex]\( A \subset B \)[/tex], then [tex]\( A \cap B = A \cup B \)[/tex]" is not always true; it holds only if A = B.
The statement "If [tex]\( A \subset B \)[/tex], then [tex]\( A \cap B = A \cup B \)[/tex]" is not always true.
If [tex]\( A \subset B \)[/tex], it means that every element in set A is also in set B.
Now, consider the intersection of A and B [tex](\( A \cap B \))[/tex]. This intersection contains all elements that are common to both sets A and B.
On the other hand, the union of A and B [tex](\( A \cup B \))[/tex] contains all elements that are in either set A or set B, or both.
Since A is a subset of B, all elements in A are already in B, which means [tex]\( A \cap B = A \)[/tex]. However, [tex]\( A \cup B \)[/tex] would just be B, because all elements in A are also in B, so [tex]\( A \cup B \)[/tex] is simply B.
Therefore, the statement "If [tex]\( A \subset B \)[/tex], then [tex]\( A \cap B = A \cup B \)[/tex]" is not true in general; it is true only if A = B .

Mowing the lawn is one of Jeremy's jobs at home. But, Jeremy's dad offered to help him this week. His dad drew the following diagram of the lawn and told Jeremy to choose one of the parts to mow. If Jeremy wants to mow the rectangle with the smaller area, which one should he choose?
Let's find out the area of the two parts separately to see which part is smaller.
Area of rectangle is given by Length * Width
Area of Part 1
Width of Part 1 is 16'
Length of Part 1 is 16-12 = 4'
So area of Part 1 is 16*4 = 64' square
Area of Part 2
Width of Part 2 is 8'
Length of Part 2 is 8'
So area of Part 2 is 8*8 = 64' square
So area of both the parts is same . Hence Jeremy may choose any of the parts.
