Katie received a sticker each time she picked up her toys. She places some of the stickers on the first page of her scrapbook as shown below. Write an equation to represent the problem using the distributive property.
The number of stickers on the first page of Katie's scrapbook is given by the equation A = 28 stickers
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The number of stickers in Katie's first page of scrapbook is A
The array of stickers is = 4 rows and 7 columns
So , number of stickers in Katie's first page of scrapbook A = 4 x 7
Number of stickers in Katie's first page of scrapbook A = 28 stickers
The total number of stickers in the scrapbook for page 2 and 3 is
A = ( 4 x 4 ) + ( 3 x 4 )
Taking the common factor as 4 , we get
A = 4 ( 4 + 3 )
By using the distributive property , we get
A = 4 x 7
A = 28 stickers
Therefore , the value of A is 28
Hence , the equation is A = ( 4 x 4 ) + ( 3 x 4 )

Find an explicit formula for the geometric sequence -3, -12, -48, -192, -768
Answer:
a4 = -3 * 4^(4-1) = -3 * 4^3 = -3*64 = -192
Step-by-step explanation:
A geometric sequence is a sequence of numbers such that the ratio of any two consecutive terms is always the same. In this case, the given sequence is -3, -12, -48, -192, -768.
To find the explicit formula for this geometric sequence, we can use the following formula:
an = a1 * r^(n-1)
where:
a1 is the first term in the sequence (-3)
an is the nth term in the sequence
r is the common ratio (the ratio between any two consecutive terms)
To find the common ratio, we can divide -12 by -3, -48 by -12, -192 by -48, and -768 by -192, and in all cases we get r = 4
Therefore, the explicit formula for this geometric sequence is:
an = -3 * 4^(n-1)
This formula can generate any term of the sequence given the value of n.
So, for example, the fourth term of the sequence, -192, can be obtained by inputting n = 4 in the explicit formula:
a4 = -3 * 4^(4-1) = -3 * 4^3 = -3*64 = -192

Let V be the set of all positive real numbers. Define + by U+V = UV-1 and . by C.V = V. Is V a vector space? Explain?
No, V is not a vector space with the operations defined in this way. Because the operations defined in this question do not satisfy the properties required for V to be a vector space.
A vector space is a collection of objects (vectors) that can be added together and multiplied ("scaled") by numbers, called scalars. These operations must satisfy certain properties to be considered a vector space.
For example, one of the properties is the associativity of vector addition, which means that (u + v) + w = u + (v + w) for any vectors u, v, and w in V. However, with the given definition of +, we have (U + V) + W = (UV-1) + W = U(VW-1) which is not equal to U + (V + W) = U(VW-1)
Another property is the distributivity of scalar multiplication over vector addition, which means that c(u + v) = cu + cv for any scalar c and any vectors u and v in V. But with the given definition of ., we have C(U+V) = C(UV-1) which is not equal to C.U + C.V = CUV-1
Furthermore, with the definition given the additive identity and the existence of additive inverse are not guaranteed.
Therefore, V is not a vector space with the operations defined in this way.

The population of a city was 34,000 at the beginning of 1937. Its
population steadily increased by 6.8% every year from 1937 to 1997.
Which of these is the closest to the population of the city at the end of
1970?
Answer:
298078.228074
Step-by-step explanation:
we add 6.8% of the population to the city each year
city population in year x + 1 = city population in year x + 6.8% of city population in year x = city population in year x + 0.068 * city population in year x = 1 * city population in year x + 0.068 * city population in year x = 1.068 * city population in year x
we multiply the population by 1.068 each year to get the next year's population
thus, over a period of y years, we would multiply the population by 1.068 y times.
start = 34000 in 1937
difference in years = 1970 - 1937 = 33
final amount = 34000 * 1.068 33 times = 34000 * 1.068^33 = 298078.228074

Which is the volume of the cone shown below
A 2016
B 1344
C 504
D 4032
The volume of a cone is given by the formula V = (1/3) * π * r^2 * h Where the volume of this cone is approximately A:2016.
What is volume of cone?The volume of a cone is a measure of the amount of space inside the cone.
It is calculated using the formula: V = (1/3) * π * r^2 * h, where V is the volume, r is the radius of the base of the cone, h is the height of the cone, and π is the mathematical constant pi (approximately equal to 3.14).
The volume of the cone is the amount of space inside the cone, and is measured in cubic units (such as cubic centimeters, cubic meters, etc.).
From the diagram, we can see that the radius of the base of the cone is 4 and the height is 8. Plugging these values into the formula, we get:
V = (1/3) * π * 4^2 * 8
V = (1/3) * π * 16 * 8
V = (1/3) * 64π
The volume of this cone is approximately A:2016.

A contour map/ plot is a way of representing a function with a two-dimensional input and a one-dimensional output.
Contours are obtained by intersecting the surface with the horizontal plane using the equation z = c. So the contour equation at height c is f(x,y) = c.
There are three types of contour lines displayed on the map:
Intermediate, Index, Supplement. The index line is the thickest contour line, and the points along the line are usually function numbered. Contours do not branch or split. Page 5 Steep slopes are represented by dense contour lines. Contour lines never intersect, but they can touch.

Function g is a transformation of the parent function f(x) = x^2. The graph of g is a translation right 5 units and up 1 unit of the graph of f. Write the equation for g in the form y = ax^2 + bx + c.
Answer: A transformation of a function such as y = f(x) is a way to change the appearance of its graph by applying certain rules to it. In this case, the graph of function g is a translation right 5 units and up 1 unit of the graph of f.
To find the equation of the transformed function g, we can take the equation of the parent function, which is y = f(x) = x^2 and apply the translation rules (right 5 units and up 1 unit) to it.
The translation right 5 units means that the x-coordinate of each point on the graph of f is increased by 5 units. So this can be written as x = x+5
The translation up 1 unit means that the y-coordinate of each point on the graph of f is increased by 1 units. So this can be written as y = y+1
Substituting x = x+5 and y = y+1 in the equation of the parent function y = x^2 gives the equation of g in the form:
y = (x+5)^2 + 1
So the equation of g is y = (x+5)^2 +1
This equation is a parabola with a vertex that

Based on the diagram below, which is closest to the height of the tree?
answer options and picture are below
Using the concept of similar triangles, the height of the tree is; Option D: 38 ft 6 inches.
How to find the side lengths of similar triangles?Similar triangles are defined as triangles that have the same shape, but then their sizes may vary. This means that equilateral triangles and squares are good examples of similar objects. Thus, if two triangles are similar, then it means that their corresponding angles are congruent and corresponding sides are in equal proportion.
Thus, applying the principle of similar triangles above to the given image, if the height of the tree is h, then we have;
5/3.25 = h/25
h = (25 * 5)/3.25
h = 38.462 ft = 38 ft + 0.462 ft
Now, conversion of ft to inches gives 0.462 ft approximately 6 inches Thus, our final answer is 38 ft 6 inches.

Given:
Omar is going to invest in an account paying an interest rate of 6% compounded monthly.
A = $32,400 in 20 years
First, convert R as a percent to r as a decimal

r = 6/100
r = 0.06 per year,

P = A / (1 + r/n[tex])^{nt}[/tex]
P = 32,400.00 / (1 + 0.06/12[tex])^{(12)(20)}[/tex]
