Find the average rate of change between n = 2 and n = 4.
Answers
The average rate of change of the sequence from n = 2 to n = 4 is 1.5, which is determined by calculating the difference in sequence values for these n values and dividing by the difference in n.
The average rate of change of a function between two points reflects the function's slope between those points. To find the average rate of change of the sequence [tex]a_n = \frac{1}{2} (2)^{n - 1}[/tex]from n = 2 to n = 4, we calculate the differences in the sequence values corresponding to these n values and divide by the difference in n itself.
The value of a_n when n = 2 is [tex]a_2 = \frac{1}{2} (2)^{2 - 1}= 1.[/tex]The value of a_n when n = 4 is [tex]a_4 = \frac{1}{2} (2)^{4 - 1}[/tex]= 4.To find the average rate of change, use the formula: rate of change = [tex](a_4 - a_2)[/tex] / (4 - 2) = (4 - 1) / (4 - 2) = 3/2 = 1.5.Therefore, the average rate of change between n = 2 and n = 4 for this sequence is 1.5.

the length of a rectangular garden is 5 feet longer than its width. The garden is surrounded by a 2-foot-wide sidewalk. The sidewalk has an area of 76 square feet. Find the dimensions of the garden.
Answers
Let the width of the garden = W
Therefore the length = W + 5
The two sidewalks alongside the length are therefore W + 5 feet long by 2 feet wide = 2(W + 5) square feet each
The 2 sidewalks alongside the width = W feet long by 2 feet wide = 2W square feet each
In addition there are the 4 corners which are each 2 feet by 2 feet = 4 square feet each
Area of sidewalk is therefore
2 * lengths = 2 * 2(W + 5) = 4W + 20
2 * widths = 2 * 2W = 4W
4 corners = 4 * 4 = 16 square feet
But we are told that the area = 76 square feet
Therefore 4W + 20 + 4W + 16 = 76
8W + 36 = 76
8W = 40
W = 5
Therefore as the width is five feet the length is 5 + 5 = 10 feet
Final answer:
By setting up equations based on the given information about the garden and the sidewalk around it, and then solving for the width, we find that the width of the garden is 5 feet, and its length is 10 feet.
Explanation:
Let's denote the width of the garden as w feet. Therefore, the length of the garden can be represented as w + 5 feet, since it is mentioned that the length is 5 feet longer than its width. Surrounding the garden, there is a 2-foot-wide sidewalk which affects the overall dimensions of the combined area (garden plus sidewalk). The width and length of this entire area would thus be w + 4 and w + 9 respectively, adding 2 feet on each side for the sidewalk.
To find the area of just the sidewalk, which is given as 76 square feet, we first calculate the area of the entire (garden plus sidewalk) rectangle, and then subtract the area of the garden. The equation for the area of the entire rectangle is (w + 4)(w + 9), and for the garden alone, it's w(w + 5). The difference between these areas gives us the area of the sidewalk:
(w + 4)(w + 9) - w(w + 5) = 76
Expanding and simplifying this equation gives us a quadratic equation to solve for w. Simplifying further:
w^2 + 13w + 36 - w^2 - 5w = 76
8w + 36 = 76
8w = 40
w = 5
Therefore, the width of the garden is 5 feet and the length is 10 feet (5 + 5).

meagan has $1.10 in dimes nickels and pennies she has three times as many nickels as pennies and the number of dimes is two less than the number of pennies how many dimes nickels and pennies dose she have please help
Answers
3x = nickels
x-2 = dimes
0.01x + 0.05(3x) + 0.10(x-2) = 1.10
0.01x + 0.15x + 0.10x - 0.20 = 1.10
0.26x-0.20 = 1.10
0.26x = 1.30
x = 1.30 / 0.26 = 5
5 pennies
5-2 = 3 dimes
3*5 = 15 nickels
check: 5 pennies = 0.05, 3 dimes = 0.30, 15 nickels = 0.75
0.75 + 0.30 + 0.05 = 1.10
pennies = 5
nickels = 15
dimes = 3

∠1 and ∠2 are vertical angles. ∠2 has a measure of 63°.
What is the measure of ∠1 ?
Enter your answer in the box.
Answers
So, if m∠1 = 63°, then m∠2 = 63°.
Vertical angles are formed when two lines intersect. The measure of the ∠1 when ∠1 and ∠2 are vertical angles is 63°.
What are vertical angles?Vertical angles are a pair of angles formed when two lines intersect each other, these angles are always opposite to each other and measure the same.
We know about the vertical angles, therefore, if the pair of angles ∠1 and ∠2 are vertical angles, then the measure of the two angles is equal.
Now, as it is given that the measure of the ∠2 is 63° and ∠1 and ∠2, therefore,
∠1 = ∠2 = 63°
Hence, the measure of the ∠1 when ∠1 and ∠2 are vertical angles is 63°.

The flat surfaces of a 3D shape are called what? Faces Edges Vertices
Answers
The flat surfaces of a 3D shape are called faces.
The faces serve as the two-dimensional polygonal areas that define the boundaries of a 3D object. In geometry, for instance, a cube is a common 3D shape that has six faces, each of which is a square. Each face is bordered by edges, which are the straight lines where two faces meet, and the corners of the faces are known as vertices (or vertex in singular form).
Examining various 3D shapes, such as the tetrahedron, which has four triangular faces, and the octahedron with its eight triangular faces, provides a clearer understanding of how faces constitute the polyhedron's shape.

in rectangle abcd measure of angle d =(3x+15) measure b =(6x-42) find measure of angle a
Answers
So, we have that m∠B = m∠D. Therefore,
[tex]6x-42=3x+15\\3x=57\\x=19[/tex]
Now, let's substitute for x back into the expression for either ∠B or ∠D to find it's angle measure.
m∠B = [tex]6(19)-42=72[/tex]
Now, remember that ∠B or ∠D are supplements of ∠A.
So, m∠B + m∠A = 180°.
That means m∠A = 180° – 72° = 108°.
That seems reasonable, because A appears to be an obtuse angle.
