If u= (-10,-3) and v= (4,8) . Proj vu is  is (640/109, 192/109).

Using this formula to determine the projection of v onto u (proj vu)

proj vu = ((v dot u) / (||u||)^2) × u

Where:

v dot u = dot product of v and u

||u|| = magnitude of u

First step is to find  the dot product of v and u:

v dot u = (-104) + (-38)

v dot u = -40 - 24

v dot u = -64

Second step to to calculate the magnitude of u:

||u|| = √((-10)^2 + (-3)^2)

||u|| = √(100 + 9)

||u|| = √(109)

Let plug in the formula

proj vu = ((-64) / (√(109))^2)× (-10,-3)

proj vu = (-64 / 109) × (-10,-3)

proj vu = (640/109, 192/109)

Therefore  the correct option is A.

The objective of the above task to to check your ability to compute various parts of a parallelogram given various inputs. See the solution attached.

A parallelogram is a basic quadrilateral with two pairs of parallel sides in Euclidean geometry. A parallelogram's opposing or facing sides are of equal length, and its opposite angles are of equal measure.

Note that the corners angles (AB,C,D)are derived as follows;

A = C = θ

B = D = Φ

A + B = 180° = π radians

for a parallelogram that is not a rectangle or square,

0 < A< 90° (0 < A < π/2),

90° < B < 180° (π/2 < B < π)

The diagonals are derived as follows:

Diagonals: d, c

d = √( a² + b² - 2ab cos(A) ) = √( a² + b² + 2ab cos(B) )

c = √( a² + b² + 2ab cos(A) ) = √( a² + b² - 2ab cos(B) )

d² + c² = 2(a² + b²)

f is onto the set of all binary strings:

This statement is false for the same reason as (e). The range of f is limited to a subset of all binary strings.

What is function?

In mathematics, a function is a relationship between two sets of elements, called the domain and the range, such that each element in the domain is associated with a unique element in the range.

a. The cardinality of the set {u | f(u) = u} is 1:

This statement is true because f(u) returns only the first third of the input string u. Therefore, if f(u) = u, then the second and third thirds of the string u must be empty, and hence u must consist entirely of the first third, which means there can be only one such string.

b. f is a total function:

This statement is false because not all binary strings can be decomposed into three parts with the described property. For instance, a binary string of length 5 cannot be decomposed in this way.

c. If |u| = 24, then f(f(u)) is not defined:

This statement is false. If |u| = 24, then u can be decomposed into three parts with 8 bits in each part. Therefore, f(u) will return the first 8 bits of u, which can be decomposed into three parts with 2, 3, and 3 bits, respectively. Therefore, f(f(u)) will return the first 2 bits of the first third of u, which is well-defined.

d. f is an injection:

This statement is false. Since f only returns the first third of its input, there can be multiple inputs that yield the same output.

e. The range of f is the set of all binary strings:

This statement is false. The range of f only consists of binary strings that are the first third of some input string that can be decomposed as described.

f. f is onto the set of all binary strings:

This statement is false for the same reason as (e). The range of f is limited to a subset of all binary strings.

After two years, Brooklyn will have more money in her savings account than Matthew.

Brooklyn's savings account grows at a slower rate than Matthew's initially but eventually catches up and surpasses Matthew's account due to the higher interest rate and monthly compounding.

a.

[tex]A = P(1 + r/n)^{nt}[/tex]

where A is the final amount, P is the initial principal (or net pay), r is the interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the number of years.

For Brooklyn saving account,

P = $625, r = 0.025, n = 12 (monthly compounding), and t = 2.

A = $625(1 + 0.025/12)^(12*2) = $686.71

For Matthew saving account,

P = $446, r = 0.04, n = 4 (quarterly compounding), and t = 2.

A = $446(1 + 0.04/4)^(4*2) = $506.84

b.

To graph Brooklyn's equation and Matthew's equation on the same graph, we can use the following equations:

Brooklyn's equation: A = 625(1 + 0.025/12)^(12t)

Matthew's equation: A = 446(1 + 0.04/4)^(4t)

Now,

The resulting graph will show the growth of each saving account over time.

The points of intersection on the graph represent the times when the two savings accounts have the same amount of money.

From the graph, we can see that the two accounts intersect at around 11 months and 23 months.

We can say that Brooklyn's savings account grows at a slower rate than Matthew's initially, but eventually catches up and surpasses Matthew's account due to the higher interest rate and monthly compounding.

Thus,

After two years, Brooklyn will have more money in her savings account than Matthew.

The value of this country's net capital outflow is $200 billion.

We have,

The formula for net capital outflow (NCO) is:

NCO = Domestic Investment - Foreign Investment

Since the problem only gives us information about domestic investment, we need to use another formula to calculate foreign investment.

The formula for national saving (S) is:

S = GDP - Consumption Expenditures - Government Spending

We can rearrange this formula to solve for foreign investment:

Foreign Investment = GDP - Consumption Expenditures - Government Spending - Domestic Investment

Substituting the given values, we get:

Foreign Investment = $1000 billion - $650 billion - $250 billion - $150 billion

Foreign Investment = $1000 billion - $1050 billion

Foreign Investment = -$50 billion

The negative sign indicates that there is a net capital inflow (i.e., foreign investment is greater than domestic investment).

Therefore, the value of this country's net capital outflow is:

NCO = Domestic Investment - Foreign Investment

NCO = $150 billion - (-$50 billion)

NCO = $150 billion + $50 billion

NCO = $200 billion

Thus,

The value of this country's net capital outflow is $200 billion.

The polar coordinates for the point (5, 5) are (5√(2), 45 degrees) or (5√(2), 225 degrees) since 225 degrees is also a valid angle between 0 and 360 degrees that corresponds to the same point.(option c)

For the point (5, 5), we can find its polar coordinates by first finding the distance r from the origin using the Pythagorean theorem:

r = √(5² + 5²) = √(50) = 5√(2)

Next, we can find the angle θ that the line connecting the origin to the point makes with the positive x-axis using trigonometry:

tan(θ) = y/x = 5/5 = 1

θ = arctan(1) = π/4 radians

Since 0 < θ < 360, we can express θ in degrees as θ = 45 degrees.

The circumference of the lollipop is 12.57 inches.

Circumference is the measurement of the distance around the outer edge of a closed curve, particularly a circle. It is the total length of the curve that makes up the boundary of the circle.

The circumference of the circle is given by the formula;

Circumference = 2 × π × radius

where π (pi) is the mathematical constant approximately equal to 3.14159265359...

Given that the radius of the round lollipop is 2 inches, we can substitute this value into the formula;

Circumference = 2 × π × 2

Using the approximate value of π as 3.14159265359..., we can calculate the circumference;

Circumference = 2 × 3.141592 × 2

Circumference ≈ 12.56

The length of the worktable is 82 inches and the width is 32 inches.

To find the length and width of the worktable, we can use a system of equations. Let's denote the width of the table by w.

Since the length is 18 inches more than twice the width, we can write:

Length = 2w + 18

The perimeter of the table is the sum of all its sides, which in this case is the sum of the length and the width, each multiplied by 2:

Perimeter = 2(length + width)

Perimeter = 2(2w + 18 + w)

Perimeter = 2(3w + 18)

Perimeter = 6w + 36

We know that the perimeter is 228 inches, so we can set up an equation:

6w + 36 = 228

Solving for w, we get:

w = 32

Now that we know the width, we can use the equation for the length to find:

Length = 2w + 18

Length = 2(32) + 18
