How to interpret Cartesian Coordinates?

Coordinates are defined as a pair of integers (Cartesian coordinates), or sporadically a letter and a number, that identify a certain place on a grid, also referred to as a coordinate plane. The x-axis (horizontal) and y-axis are the two axes that make up a coordinate plane (vertical).

Given that the location of the entrance is at (6, 5).

To reach the waterfall, you need to go 3 km to the left and 4 km down from the park entrance.

The x-coordinate decreases to the left side of a point and increases to the right side of a point.

The y-coordinate decreases to a downward point and increases upward a point.

The x-coordinate of the waterfall is 6 - 3 =3

Simply put, trigonometric functions—also referred to as circular functions—are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle. Sine, cosine, tangent, cotangent, secant, and cosecant are the fundamental trigonometric functions.

Given a right triangle,

the base angle is 61° and the length of the base is 17

using tangent to find the value of x

tanФ = perpendicular/base

What is a parallelogram?

A parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides

Remember that the opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

This implies that y + 58 = 180

Making y the subject of the relation

y=180-58

y=122⁰

Also, since the other two opposite angles are not given, then it means that x=y = 180/2 = 90

The value of w = 16. The number 24 has a place value of two due to the presence of two full sets of tens.

What is meant by value?The value describes the value of each digit in relation to its position in the number. The place value and face value of the digit are multiplied to arrive at the answer. Value equals Place Value minus Face Value.Value is concerned with how much something is worth, whether in monetary terms or in terms of significance. It can mean "identify how much something is worth" like a reward valued at $200 or it can indicate "hold something in high esteem" like "I value our friendship."The occurrence of two complete sets of tens gives the number 24 its place value of two.

Let the be ST = RU = PQ

S T = w,  RU= -3w + 44,  and  PQ = -5w + 68

Then by simplifying the above equation we get,

(w) + (-3w + 44) + (-5w + 68) = 0

w - 3w + 44 - 5w + 68 = 0

Group like terms

w - 3w - 5w + 44 + 68 = 0

Add similar elements: w - 3w - 5w = -7w

-7w + 44 + 68 = 0

Add the numbers: 44 + 68 = 112

-7w + 112 = 0

Move 112 to the right side

-7w = -112

Divide both sides by -7

What are the properties of trapezium?

The following characteristics apply to a trapezium:

Similar to other quadrilaterals, the trapezium's four angles add up to 360°.

Two of a trapezium's sides are parallel, whereas the other two aren't.

Regular trapezium diagonals are divided by one another.

In a trapezium, the mid-length segment's is equal to half the total length of the parallel bases.

A trapezium created by two parallel sides and one non-parallel side has two pairs of neighbouring angles that add up to 180 degrees.

We know that the length of the mid-segment is equal to half the sum of the parallel bases, in a trapezium.

Thus,

TS +PQ = 1/2 (UR)

w - 5w + 68 = 1/2 (-3w + 44)

2(-4w + 68) = -3w + 44

-8w + 136 = -3w + 44

136 - 44 = -3w + 8w

The ratio of the side lengths, yellow to green

We see yellow is 36 and green is 60, so we just put that slash mark in between as indicated in the directions, giving us

36/60. We can reduce this to it's simplistic form of 3/5

The ratio of the perimeters, yellow to green.

To find the perimeter, we multiply the side by 5

Yellow; 36x5= 180

Green; 60x5= 300

We put that ratio slash... 180/300. Reducing it comes out to 90/150 > 30/50 > 3/5 also...

And that's because the polygons are similar.

Since the polygons are similar... what would be the ratio for the areas...

Yep, 3/5

Last is to find the area of the green.

The yellow is 45 and the ratio is 3/5. We can write the equation as a ratio

[tex] \frac{45}{x} = \frac{3}{5} [/tex]

Now if we cross multiply;

Answers

The number of hits by each player are 1195 and 1470 hits, respectively

How to determine the number of hits by each player

Let's call the number of hits that Ricky got "x".

Then, Pedro got x + 275 hits.

The total number of hits for both players is x + (x + 275) = 2665

Solving for x, we get 2x + 275 = 2665

Subtracting 275 from both sides,

We get 2x = 2665 - 275 = 2390

Dividing both sides by 2,

We get x = 2390 / 2 = 1195

So Ricky got 1195 hits and Pedro got 1195 + 275 = 1470 hits.

Equation of the thine that passes through the point (-6,-8) and is parallel to the line x-2y=6

Answers

The rquired equation of the line is x + 2y = - 10

Slope-intercept form of a line:  

The slope-intercept form of a line is given by

             y = mx + c  

Where m = slope and c = y-intercept  

Note: The slope of two parallel lines will have the same slope

Here we have

The point (-6, -8) and the line x - 2y = 6 --- (1)

Let the equation y = mx + c ---- (2)  is the equation of the line  that passes through (-6, -8) and parallel to x - 2y = 6  

As we know the parallel  lines will have the same slope

=> Slope of line (1) = Slope of line (2)

Here x - 2y = 6

=> 2y = - x + 6

=>  y = -x/2 + 3  which is in the form of y = mx + c

=> Slope of line = - 1/2

Therefore, the Slope of lines (2) = -1/2

=> y = (-1/2)x + c

=> 2y = -x + 2c --- (3)

Given that line passes through (-6, -8)

=> 2(-8) = - (-6) + 2c

=> - 16 = + 6 + 2c

=> 2c = -10

=> c = -5

=>  y = -x/2 + (-5)

=>  y = -x/2 - 5

=> 2y = - x - 10

=> x + 2y = - 10

B. 175.84 square inches
C. 100.48 square inches
D. 25.12 square inches

Answers

Answer:

B.    175.84 square inches

Step-by-step explanation:

The pizza is shaped like a circle

Area of a circle = π r² where r is the radius

r = d/2 where d = diameter

Here d = 16 in

r = 16/2 = 8

Total area of pizza = π · 8² = 64 π

If 1/8th of the pizza was consumed balance = 1-1/8 = 7/8

7/8 of the total area = 7/8 x 64π = 56π = 175.84 square inches

a small business owner is applying for a small business loan and has been approved for a $50,000 loan with a 6.15% annual interest. the first loan is a simple interest rate, the second loan compounds interest quarterly, and the third loan compounds interest continuously. the small business owner plans to pay off the loan in three years and 7 months. determine the total value of the loan with simple interest.

Answers

Answer and Explanation:

To calculate the total value of the loan with simple interest, we can use the formula:

Loan amount x (Interest rate x Time in years) = Simple interest

Where,

Loan amount = $50,000

Interest rate = 6.15%

Time in years = 3 years + 7 months / 12 months/year = 3.58 years

So,

Simple interest = $50,000 x (6.15% x 3.58) = $10,439

Therefore, the total value of the loan with simple interest would be $50,000 + $10,439 = $60,439.
