Which coordinate pair identifies a point in the third quadrant of the coordinate plane?

A) (15, 10)
B) (15, −10)
C) (−15, 10)
D) (−15, −10)

Answer:

P1 (6, 2/3 π)

P2 (6, 10/3 π)

P3 (6, 14/3 π)

Step-by-step explanation:

To find the other three points you take into account that if you sum 2π to one coordinate you have the same point.

Hence, by adding 2π to -4π/3, and again other two times:

[tex]-\frac{4}{3}\pi+2\pi=\frac{2}{3}\pi\\\\\frac{2}{3}\pi+2\pi=\frac{8}{3}\pi[/tex]

[tex]\frac{8}{3}\pi+2\pi=\frac{14}{3}\pi[/tex]

hence, the other two points are

P1 (6, 2/3 π)

P2 (6, 10/3 π)

P3 (6, 14/3 π)

Radius, r= 6/2 = 3 cm

Answer:

42 kg.m/s.

Step-by-step explanation:

Just add them:

= 22 + 20 = 42 kg. m/s.

The combined momentum of Object A with +20 kg.m/s and Object B with +22 kg.m/s is +42 kg.m/s, as both are moving in the same direction and there is no need to account for direction beyond the sign.

To determine the combined momentum of two objects, we simply need to add their individual momentums together, provided that they are moving in the same direction or dimension. In this case, Object B has a momentum of +22 kg.m/s and Object A has a momentum of +20 kg.m/s. Since both momentums are positive, they are both in the same direction (presumably the +x-direction). The combined momentum is the sum of the two:

Combined momentum = Momentum of Object A + Momentum of Object B

Combined momentum = +20 kg.m/s + +22 kg.m/s = +42 kg.m/s

The combined momentum of the two objects is +42 kg.m/s.

Answer:

1) 6 days

2) Captain Salamander

Step-by-step explanation:

1) a = 243

r = ⅔

Sn = 650

650 = 243[(⅔)^n - 1]/(⅔ - 1)

(⅔)^n = 79/729

n ln(2/3) = ln(79/729)

n = 5.480683381

2) a = 180

d = -22

S5 = (5/2)[2(180) + 4(-22)]

S5 = 680 > 650

Answer:

The system of equation to determine the quantity of nickels and quarters is simultaneous equation.

Nickels = 17

Quarters = 22

Step-by-step explanation:

Given

Let n represent number of nickels

Let q represent number of quarters

From line 1 of the question, we understand that

Total coins = 39

So, n + q = 39 because the made up of the nickels and the quarters

It's also stated that the total value of these 39 coins is $6.35.

First, it should be noted that

1 nickel is worth 0.05 and 1 quarter is worth 0.25, we can represent the total value of the coins with the following equation

0.05n + 0.25q = 6.35

At this point, we have two equation such can be solved simultaneously

n + q = 39 ------- (1)

0.05n + 0.25q = 6.35 ------- (2)

So, the system of equation to determine the quantity of nickels and quarters is simultaneous equation.

Solving further.....

Make q the subject of formula in equation (1)

q = 39 - n

Substitute 39 - n for q in equation 2

0.05n + 0.25q = 6.35 becomes

0.05n + 0.25(39 - n) = 6.35

0.05n + 9.75 - 0.25n = 6.35

Collect like terms

0.05n - 0.25n = 6.35 - 9.75

-0.2n = -3.4

Divide through by -0.2

-0.2n/-0.2 = -3.4/-0.2

n = 17

Recall that q = 39 - n

Substituton 17 for n in this equation

q = 39 - 17

q = 22

Hence, there are 17 nickels and 22 coins

Let x represent Kim's age

"Bob is 4 years older than twice Kim's age"

Thus, Bob's age =

4 + 2x years

"Paul is 1 year younger than 3 times Kim's age."

Thus. Paul's age is

(3x - 1) years

If Bob's age and Paul's age is equal, we can write:

2x + 4 = 3x + (-1)

Thus, the required expression is

Option D)

The equation can be used to determine Kim’s age will be 2x + 4 = 3x + (–1). Then the correct option is D.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Use the information to write an equation with variables on both sides. Let x represent Kim’s age.

Bob is 4 years older than twice Kim’s age. Then the age of the Bob will be in terms of x.

B = 2x + 4

Paul is 1 year younger than 3 times Kim's age. Then the age of the Paul will be in terms of x.

P = 3x – 1

Bob and Paul are the same age.

B = P

Put the value of B and P, then we have the equation will be

2x + 4 = 3x – 1

2x + 4 = 3x + (–1)

Then the correct option is D.

The area of Brian's cake's top = base x height

                                                  = 13 x 9

                                                  = 117 square inches

Area of Nancy's cake's top = [tex]\frac{1}{2\\}[/tex] x base x height

                                             = [tex]\frac{1}{2}[/tex] x 15 x 12

                                             = 6 x 15

                                             = 90 square inches

Therefore, Brian's cake's top has a greater area than Nancy's.

Answer:

Brian's parallelogram-shaped cake top had the greater area. It was 27 in² greater than Nancy's cake top.

Step-by-step explanation:

To find the area of a parallelogram, use the formula A = b × h, where A is the area, b is the base and h is the height. Substitute the base and height into the equation.

A = 13 × 9

Then work out the equation to get:

117 = 13 × 9

This means that Brian's cake top has an area of 117 in².

Next, find the area of a triangle using the formula A = [tex]\frac{bh}{2}[/tex], where A is the area, b is the base, and h is the height. Substitute the base and height into the equation.

A = [tex]\frac{15*12}{2}[/tex]

The * symbol means the same as multiply.

Then work out the equation to get:

180 = [tex]\frac{15*12}{2}[/tex]

This means that Nancy's cake top has an area of 90 in².

We can see that Brian's cake top has a greater area than Nancy's already, but to find out how much greater, just subtract 90 from 117:

117 - 90 = 27

Hence, Brian's cake top has a greater area of 27 in².

A The two bases of a rectangular prism are rectangles, while the two bases of a triangular prism are triangles.

The difference between a rectangular prism and a triangular prism is The two bases of a rectangular prism are rectangles, while the two bases of a triangular prism are triangles, the correct option is 1.

Suppose you've got a triangle. Now, stretch it up so as to make a stack of triangles up above another. This new 3d object is called a triangular prism.

Usually, when we talk about triangular prism, we talk about the triangular prism, whose stack goes straight up, thus, we talk about a right triangular prism.

We are given that;

A rectangular prism and a triangular prism

Now,

A prism is a three-dimensional shape that has two congruent and parallel bases and rectangular faces that connect the bases. The shape of the base determines the name of the prism. For example, a rectangular prism has rectangular bases and a triangular prism has triangular bases.

The other options are incorrect because:

Option 2 is false. Both prisms have two bases.

Option 3 is false. Both prisms have two bases.

Option 4 is false. A rectangular prism has six faces (two bases and four lateral faces) and a triangular prism has five faces (two bases and three lateral faces).

Therefore, the answer will be the two bases of a rectangular prism are rectangles, while the two bases of a triangular prism are triangles.

The approximate corresponding height of the parallelogram is 4.8 units.

Option C is the correct answer.

Parallelogram is a quadrilateral that has two pairs of parallel sides.

In a parallelogram, opposite sides and angles are equal.

The adjacent angles add up to 180 degrees.

We have,

The area of a parallelogram is equal to the product of its base and height. Therefore, we can find the height of parallelogram ABCD by dividing its area by the length of its base.

The area of parallelogram ABCD is equal to the area of triangle ABD, which has the same base as parallelogram ABCD and the same height as parallelogram ABCD.

Therefore, we can find the area of triangle ABD by dividing the area of parallelogram ABCD by 2.

Let h be the height of the parallelogram ABCD.

Area of triangle ABD

= (1/2) x base x height

= (1/2) x 8.6 units x h

Area of parallelogram ABCD

= base x height

= 8.6 units x h

Dividing the area of parallelogram ABCD by 2.

Area of triangle ABD

= (1/2) x 8.6 units x h

= 4.3 units x h

We know that the area of the parallelogram is greater than the area of the triangle because the parallelogram contains the triangle.

Therefore, the height of the parallelogram must be greater than the height of the triangle.

Let's say that the height of the parallelogram is approximately 4.8 units. Then, the area of the triangle is approximately:

Area of triangle ABD

= (1/2) x 8.6 units x 4.8 units

= 20.64 square units

Now,

Area of parallelogram ABCD.

= 8.6 units x 4.8 units

= 41.28 square units

This area corresponds to a height of approximately 4.8 units.

Therefore,

The approximate corresponding height of the parallelogram is 4.8 units.
