You deposit $320 in an account that earns simple interest at an annual rate of 7.5% IS there enough money in the account after 3 years to buy a game console that costs $400?
Answer:
no
Step-by-step explanation:
simple interest formula:
final amount = initial balance * (1 + interest rate * time)
rate = 7.5% = 0.075
initial balance = 320
time = 3
is the final amount of 320 * (1 + 0.075 * 3) greater than or equal to 400?
320 * (1 + 0.075 * 3) = 392 so no

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.

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:

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

b. Find RS and ST.
The value of y is 58 and RS is 55.25 and ST is 17.5.
What is Equation?Equation is an expression that consists of variables, constants, and operators, and expresses a relationship between them. It is a mathematical statement that two expressions are equal. Equations can be used to solve a wide variety of problems in mathematics, science, engineering, and other fields. Examples of equations include the Pythagorean Theorem, the equation of a circle, and the equation of a line. Equations can be written in a variety of forms, such as symbolic, graphical, and numerical.
The value of y can be found by solving the equation 8y+4=58. By subtracting 4 from both sides, we get 8y=54.
Dividing both sides by 8, we get y=6.75.
Therefore, RS=8y+4=8(6.75)+4=55.25 and
ST=2y+4=2(6.75)+4=17.5.

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
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.

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

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
