(a)The resultant of two vectors has the largest magnitude when the angle between them is 180 degrees. (b)The expression k.(a.B) is a scalar (c)  Given that the resultant force is 65 N [E 22° N], the equilibrant force is 65 N [W 22° S] (d) Given P = 9, a unit vector in the direction opposite to P is -P/|P|. (e)The expression (K.K)k + k in its simplest form is K(k + 1).

a) The resultant of two vectors has the largest magnitude when the angle between them is 180 degrees. When two vectors are in opposite directions (angle of 180 degrees), their magnitudes add up to produce the largest resultant magnitude.

b) The expression k.(a.B) is a scalar.The dot product of two vectors results in a scalar value.

c) Given that the resultant force is 65 N [E 22° N], the equilibrant force is 65 N [W 22° S]. The equilibrant force has the same magnitude as the resultant force but acts in the opposite direction.

d) Given P = 9, a unit vector in the direction opposite to P is -P/|P|.  A unit vector in the opposite direction to a vector P is obtained by multiplying P by -1 and dividing by the magnitude of P.

e) The expression (K.K)k + k in its simplest form is K(k + 1). Explanation: Since K is a scalar, K.K simplifies to K², and k + k simplifies to 2k. Therefore, the expression becomes K²k + 2k, which can be further simplified to K(k + 1).

Answer:

y=3x-25

Step-by-step explanation:

On solving the provided question, we can say that - Jasmine receives 2 shares, or $10 (2 x $5)and Holly receives 4 shares at $5 each, for a total of $20.

A ratio is an ordered pair of numbers a and b that is expressed as a / b, with b not equal to zero. An equation equating two ratios is known as a ratio. For instance, the ratio might be represented as 1:3 if there were 1 boy and 3 girls (for every boy he has 3 girls) 3/4 are girls, while 1/4 are boys. A part is a quantity, ratio of amount or size between two or more items.

$30 is the entire sum.

Gertie distributes $30 in a 2:4 ratio.

2 plus 4 equals 6, the total number of shares.

$30 divided by six equals $5 for each share.

Step-by-step explanation:

The volume of the solid generated when the trapezoid is rotated about side DA is approximately 1586.6 cubic units (rounded to the nearest tenth).

A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder, or a sphere. Different shapes have different volumes.

Given:

DC = 7

DA = 6

DE = 6

AB = 14

Height of the trapezoid:

ED = (DC/AB) * EA = (7/14) * EA = 0.5 * EA

Height = EA - ED = EA - 0.5 * EA = 0.5 * EA

Circumference of the cylindrical shell:

Circumference = 2 * π * AB = 2 * π * 14

Thickness of the cylindrical shell:

Since the trapezoid is being rotated about side DA, the thickness (Δx) will vary along DA. We'll integrate with respect to x from 0 to 6 (the length of DA).

Volume of the solid generated:

Volume = ∫(0 to 6) [2 * π * 14 * 0.5 * EA * Δx]

Substituting EA = DE + DA = 6 + 6 = 12Volume = ∫(0 to 6) [2 * π * 14 * 0.5 * 12 * Δx]

Integrating:

Volume = 2 * π * 14 * 0.5 * 12 * [x] from 0 to 6

Volume = 2 * π * 14 * 0.5 * 12 * (6 - 0)

Volume = 504 * π

Approximating to the nearest tenth:

Volume ≈ 504 * 3.14 ≈ 1586.6 cubic units (rounded to the nearest tenth)

Therefore, the volume of the solid generated when the trapezoid is rotated about side DA is approximately 1586.6 cubic units (rounded to the nearest tenth).

The total number of students in the sample who visited city bars every weekend is an example of a count or a discrete variable.

In this scenario, the chancellor of Ferris State University wanted to investigate the portion of students who visited city bars every weekend. To gather data, the advisor took a random sample of 250 students from the university. The variable of interest, in this case, is the number of students in the sample who visited city bars every weekend.

Since the variable represents a count of students, it is a discrete variable. Discrete variables take on specific values and cannot be divided into smaller units. In this context, the total number of students who visited city bars every weekend in the sample can only be a whole number, such as 0, 1, 2, and so on.

Count variables are commonly used in statistical analysis to study events or behaviors that can be counted, such as the number of occurrences of an event, the number of individuals in a category, or in this case, the number of students who visited city bars every weekend. By examining the count variable, researchers can gain insights into the prevalence or frequency of a particular behavior or event within a population.

I think you are right!

Step-by-step explanation:

True. Hexadecimal numbers are written using the base 16 number system, where digits range from 0 to 9 and A to F. They are commonly used in computer systems for concise representation and easy conversion to binary.

In the hexadecimal number system, there are 16 symbols used to represent values, namely 0-9 and A-F. Each digit in a hexadecimal number represents a multiple of a power of 16.

The symbols 0-9 represent the values 0-9, respectively. The symbols A-F represent the values 10-15, respectively, where A represents 10, B represents 11, C represents 12, D represents 13, E represents 14, and F represents 15.

For example, the hexadecimal number "3F" represents the value (3 * 16^1) + (15 * 16^0) = 48 + 15 = 63 in decimal.

Similarly, the hexadecimal number "AB8" represents the value (10 * 16^2) + (11 * 16^1) + (8 * 16^0) = 2560 + 176 + 8 = 2744 in decimal.

Hexadecimal numbers are commonly used in computer systems, as they provide a convenient way to represent large binary numbers concisely. Each hexadecimal digit corresponds to a four-bit binary number, allowing for easy conversion between binary and hexadecimal representations.

Answer:

Distance of L from AB = 0.6 in.

m∠ABC = 60°

Step-by-step explanation:

Given:

LB = 1.2 in

LC = 0.6 in

We have to find the distance of point L to AB or length of LD.

From right triangle ΔBCL,

Sin(∠LBC) = \(\frac{\text{Opposite side}}{\text{Hypotenuse}}\)

                 = \(\frac{LC}{LB}\)

                 = \(\frac{0.6}{1.2}\)

                 = \(\frac{1}{2}\)

m∠LBC = 30° [Since ∠LBC is an acute angle]

Since, ∠LBC ≅ ∠LBA

m∠LBA = 30°

Now from right triangle ΔLDC,

sin(∠LBA) = \(\frac{LD}{BL}\)

sin(30)° = \(\frac{LD}{1.2}\)

\(\frac{1}{2}=\frac{LD}{1.2}\)

LD = 0.6

Therefore, Distance of point L from AB is 0.6 in.

m∠ABC = m∠ABL + m∠LBC

             = 30° + 30°

             = 60°

The area of the billboard is \(1,632,400 cm^{2}\), Option (d) is correct.

Since the linear scale factor f=20, then the billboard area:

A = \(77.53\)×\(20^{2}\)

= \(1,632,400 cm^{2}\)

Linear scale Factor:

The size of the enlargement/reduction is represented by the scale factor. For example, a scale factor of 2 means that the new shape is twice the original shape. A scale factor of 3 means that the new shape is three times the size of the original shape.

Answer:

The growth rate is 7.2%

Step-by-step explanation:

First thing we need to do here is to set up an exponential equation;

This can be written as follows;

F = I(1 + r)^t

where F is the future value = 20,000

I is the initial value = 10,000

r is the rate in percent which we want to calculate

t is time in years = 10 years

Substituting the values in the question into the exponential equation, we have;

20,000 = 10,000(1 + r)^10

divide both side by 10,000

2 = (1+r)^10

Find the 10th root of both sides

1+ r = 2^(1/10)

1 + r = 1.07177346254

r = 1.07177346254-1 = 0.07177346253

Let’s approximate r as 0.072

Now this to percentage?

That would be 72/1000 * 100% = 7.2%

An equivalent expression by combining like terms, we need to group the terms with the same variable exponent, add or subtract them as appropriate, and simplify the resulting expression

Combining like terms refers to the process of adding or subtracting variables with the same exponent and any constants present. The method of combining like terms is similar to how you add or subtract similar items. The key is to simplify the expression by making it as short as possible. Here is an example to demonstrate how to write an equivalent expression by combining like terms:

W 10 w - 4

To combine like terms, we first group all the like terms together, that is, the terms with the same variable exponent. Here, we can see that both terms have the variable w, so we can add them together.

However, the first term has a coefficient of 10, which means it has ten times the value of the second term. Therefore, we can rewrite the expression as follows:

W(10w - 4)

We have now combined like terms, but we can further simplify this expression. The term inside the parenthesis can be simplified by factoring out the common factor 2 from the two terms. This results in:

W(2 * 5w - 2)W(2(5w - 1))

The expression is now in its simplest form, and we have written an equivalent expression by combining like terms.

To summarize, to write an equivalent expression by combining like terms, we need to group the terms with the same variable exponent, add or subtract them as appropriate, and simplify the resulting expression as much as possible by factoring out common factors.

Answer: 24, b

Step-by-step explanation:

So it said "In the Math Club", 67% are not in the literature club. We also know that this 67% is 16 people.

Now we can set up an equation to find the total number of people in the math club. Let's say the total number of people in the Math club is x, so 0.67x = 17, and x = 25.37 rounded. So if 25 people in total, 16 not in the literature club, then that means 25-16 = 9 people are in both the Math club and the Literature club.

So of the students "Not in the Math Club", it said that 78 percent are not in the Literature Club. This means 22 percent are in the literature club. We also know 4 people are in the literature club.

Now we can set up an equation to find the total number of people not in the math club. Let's say the total number of people not in the Math club is x, so 0.22x = 4, x = 18.18 rounded. So if 18 in total, 4 in the literature club, than 14 not in the literature club.

Since x = 9, and y = 14, x+y will equal 23, rounding up to 24 since we rounded down the total number of people.

On solving the equation Ý = 140 + (-0.0667)X, the value for blood pressure is obtained as 129.328 mm Hg.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The equation is given as Ý = 140 + (-0.0667)X.

An amount of medication of 160 mg is found to result in a blood pressure of 127.74 mm Hg.

Here the value of X is X = 160.

The predicted blood pressure will be -

Ý = 140 + (-0.0667)160

Ý = 140 - 10.672

Ý = 129.328

The predicted blood pressure value is 129.328 mm Hg.

Here the predicted blood pressure value 129.328 mm Hg is greater than the actual blood pressure value 127.74 mm Hg.
