Answer:

C , D

Step-by-step explanation:

The component form of a vector is given as < x, y >, where x describes how far right or left a vector is going and y describes how far up or down a vector is going.

The component form of vector C is <1, 5> and the component form of vector D is <8, 2>. The components represent the magnitudes of the vector's displacements in the x and y directions, respectively.

To write the component form of a vector, we simply list its components, which are the numerical values that represent the vector's magnitude and direction in each dimension. In this case, we have vector C with components C<1, 5> and vector D with components D<8, 2>.

The components of a vector represent its position or displacement along the coordinate axes. In a two-dimensional Cartesian coordinate system, the first component represents the displacement along the x-axis (horizontal direction), and the second component represents the displacement along the y-axis (vertical direction).

For vector C, the component form is written as <1, 5>, where the first component is 1 and the second component is 5. This means that vector C has a displacement of 1 unit in the x-direction and 5 units in the y-direction.

Similarly, for vector D, the component form is <8, 2>, indicating a displacement of 8 units in the x-direction and 2 units in the y-direction.

Therefore, the component form of vector C is <1, 5> and the component form of vector D is <8, 2>. The components represent the magnitudes of the vector's displacements in the x and y directions, respectively.

Answer:

no

Step-by-step explanation:

Generally you can't really compare two functions with a different denomination, and you want to multiply the fractions by some fraction: [tex]\frac{a}{a}[/tex] which simplifies to one so we're not changing the value of the fraction at all but it helps so we have the same denominator.

You'll notice we can multiply 4 by 2 to get 8, which would give us the same denominator as 8.

[tex]\frac{23}{4}*\frac{2}{2}=\frac{46}{8}[/tex]

Now it's much easier to compare: [tex]\frac{47}{8}\text{ and }\frac{46}{8}[/tex] and here all we have to compare is the numerators, and obviously 47 is greater than 46 so the 47/8 is greater than the 23/4. This means 47/8 is not less than 23/4

The most appropriate choice for slope of a line will be given by-

Slope of the line = [tex]\frac{-19}{12}[/tex]

What is slope of a line?

At first it is important to know about line.

Line is a geometrical object that has only length but no breadth and no height.

Slope of a line is the tangent of the angle which the line makes with the positive direction of x axis

If [tex]\theta\\[/tex]  is the angle which the line makes with the positive direction of x axis, then slope of the line is given by

m = [tex]tan\theta[/tex]

If the line passes through ([tex]x_1,y_1[/tex]) and ([tex]x_2, y_2[/tex]) , then

slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Here,

[tex]x_1 = -3, y_1 = 9. x_2 = 9, y_2 = -10[/tex]

Slope = [tex]\frac{-10 - 9}{9 - (-3))}[/tex]

Finance charge = $93.00

The interest you'll pay on a loan is defined as a finance charge, and it's most commonly used in the context of credit card debt. A financing fee is computed by taking your annual percentage rate, or APR, the amount you owe, and the time period into account.

Given that,

Interest rate = 15.5%

Date: 1-3 (3 days)

Average daily balance = amount paid × days

                                      = $200 × 3 = $600  

Date: 4-20 (17 days)

Average daily balance = amount paid × days

                                      = $300 × 17 = $5100  

Date: 21-30 (10 days)

Average daily balance = amount paid × days

                                      = $150 × 10 = $1500  

So, total average daily balance for the month

= $(600+5100+1500)

= $7200

Now, the finance charge = $7200 × (15.5÷12)

                                         = $93.00

If a rectangular tabletop has an area of [tex]28\frac{1}{8}[/tex] square feet and the length of [tex]6\frac{1}{4}[/tex] feet, then the width of the tabletop is  [tex]4\frac{1}{2}[/tex] feet

The area of the tabletop =  [tex]28\frac{1}{8}[/tex] square feet

Convert the mixed fraction to simple fraction

[tex]28\frac{1}{8}[/tex] square feet = 225/8 square feet

The length of the tabletop =  [tex]6\frac{1}{4}[/tex] feet

Convert the mixed fraction to simple fraction

[tex]6\frac{1}{4}[/tex] feet = 25/4 feet

Area of the rectangle = Length ×  width

Width of the rectangle = Area of the rectangle ÷ Length of the rectangle

Substitute the values in the equation

Width of the rectangle = 225/8 ÷ 25/4

= 225/8 × 4/25

= 9/2 feet

Convert the simple fraction to mixed fraction

9/2 feet = [tex]4\frac{1}{2}[/tex] feet

I graphed it

The measure of angles 1, 2, and 3 in exercise 11. are 100°, 80°, and 100°.

The measure of angles 1, 2, and 3 in exercise 12. are 47°, 133°, and 47°.

The measure of angles 1, 2, and 3 in exercise 13. are 80°, 80°, and 100°.

The measure of angles 1, 2, and 3 in exercise 14. are 94°, 86°, and 94°.

For 11. part:

Considering a transversal p that cuts two parallel lines l and m,

Each pair of internal angles on the same side of a transversal that intersects two parallel lines are supplementary.

m∠1 + 80° = 180°

m∠1 = 180° - 80°

m∠1 = 100°

Similarly, m∠1 + m∠2 = 180°

⇒ 100° + m∠2 = 180°

⇒m∠2 = 180° - 100°

⇒m∠2 = 80°

and also, m∠2 + m∠3 = 180°

⇒ 80° + m∠3 = 180°

⇒m∠3 = 180° - 80°

⇒m∠3 = 100°

Therefore, m∠1 = 100°, m∠2 = 80° and m∠3 = 100°.

For 12. part:

m∠3 + 133° = 180°(interior angles are supplementary)

m∠3 =  180° - 133°

⇒m∠3 = 47°

m∠2 = 133°(alternate interior angles)

The angle vertically opposite to 133° would also be 133°.

So, 133° + m∠1 = 180°( interior angles are supplementary)

m∠1 = 47°

Therefore, m∠1 = 47°, m∠2 = 133° and m∠3 = 47°.

For 13. part:

m∠3 = 100° (vertically opposite angle)

Let's assume the angle adjacent to ∠3 is x.

m∠3 + m ∠x = 180° (Linear pair property)

100° + m ∠x = 180°

m ∠x = 180° - 100°

m ∠x = 80°

Therefore, m∠1 = m∠2 = m ∠x  = 80°(Corresponding angles are equal.)

For 14. part:

m∠1 + 86° = 180°(co-interior angles are supplementary)

m∠1 = 180°- 86° = 94°

The angle vertically opposite to m∠1 is also equal to 94°.

94° + m∠1 = 180°(co-interior angles are supplementary)

m∠2 = 86°

Similarly, the angle vertically opposite to m∠2 is also equal to 86°.

86° + m∠3 = 180°(co-interior angles are supplementary)

m∠3 = 94°

Therefore, m∠1 = 94°, m∠2 = 86° and m∠3 = 94°.
