What is the image of the point (6, -4) when rotated 180 degrees anticlockwise about the origin?
(-6, -4)
(-6, 4)
(4, 6)
(-4, -6)

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Answer:$360

Step-by-step explanation:

I=PRT

I=12/100×2000×1.5

I=24×1.5

I=$360

$2703.75

Why? Because...

you count all the squares one by one and then you multiply all the squares by 52.50 because that's how much one square cost

Or you can split the playground up into 3 shapes; a rectangle and 2 triangles

The rectangle is 4 by 11 feet

Triangle 1 is 2 by 3 feet

Triangle 2 is 3 by 3 feet

The formula for a rectangle is base × (times) height

so...

4x11=44

The formula for a triangle is \(\frac{BaseHeight}{2}\)

so for Triangle 1...

its area is 3

and for Triangle 2...

its area is 4.5

The area of the playground is

44+3+4.5=51.5

because each square costs $52.50 you have to multiply each square by 52.50

51.5x52.50=2703.75

Answer: 39.5

Step-by-step explanation:

the square is 8 by 4.  8x4=32

and the upper triangle is 2 by 3, 2 x 3 = 6, 6 / 2 = 3, so the area of the triangle is 3.

the triangle below is 3 by 3, 3 x 3 = 9, 9 / 2= 4.5 or 4 1/2.

32+3+4.5= 39.5. the area of the shape is 39.5

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Answer:

Step-by-step explanation:

(A) Let 1 dozen be c

So, 7 dozens = \(4\frac{2}{3}\) cups

4c = \(4\frac{2}{3}\)

c = \(\frac{14}{3}\) x 4

c = \(18\frac{2}{3}\) cups

(B) Answering nothing is better than giving wrong answer.

Answer: 3 is 0 and 4 is unidentified

Step-by-step explanation:

The horizontal line has a slope of zero, think of it as you can walk on it or not. Since four has all X's as eight that creates a vertical slope which cannot be walked on.

Thanks for the opportunity to help you! :)

1. m/slope=6/1 or 6. Use the first two points for the formula y₂-y₁/x₂-x₁. B

2.m=-4 or -12/3. Use the slope formula and substitute the points. G

3. m=zero. I

4.m=undefined. A

Answer:

The area increases by 25.68 \(cm^2\)

Step-by-step explanation:

The surface area of a cuboid is 2lw + 2wh + 2lh, where l = length, w = width, and h = height. The current surface area is 2*18*3.4 + 2*3.4*30 + 2*18*30, which is 1406.4. If the height is increased by 0.6 cm, the surface area will be 2*18*3.4+2*3.4*30.6+2*18*30.6, which is 1432.08. The difference is surface area is 25.68 \(cm^2\)

Answer:

I think H

Step-by-step explanation:

Answer:

Mean: 10

Median: 11

Step-by-step explanation:

To find the mean you have to add up all the numbers then divide by how many there are.

E.g in 1,2,3,4 there are four numbers there so you add them all up and divide by 4

To find the median you have to sort out the numbers and put them in order of smallest to largest. Then you find the middle number.

E.g 2,3,1,4,5

You put them in order: 1,2,3,4,5

Then find the middle which is 3.

I hope you found this useful.

Answer: Mean is 9.111 and the Median is 5 I think.

Step-by-step explanation:

Mean= Add all numbers up then divide by how many numbers

Median= Numeric order, then count how many numbers, and then divide by 2 if its odd round up to nearest ones digit.

Negative 3, negative 2.4, negative 1.5, negative 2 and one-fourth, negative 1 and one-eighth

Answer:

75 hairs/ day =  525 hairs / week

Step-by-step explanation:

so your base question for this is 75 hairs/ day =? h/ week. how? if the dog is losing 75 hairs per day, then you would do 75 x 7 becuase there are 7 days in a week. the answer to that would give you how many hairs the dog was losing per week. (see attached image for reference)

The system of linear equations is given as:

y = 1/4x - 1

x - 4y = 4

To find the solution, we can substitute y in the second equation with 1/4x - 1:

x - 4(1/4x - 1) = 4

x - x + 4 = 4

4 = 4

The equation 4 = 4 is always true, which means that the system of linear equations has infinitely many solutions.

Therefore, the answer is:

Infinitely many solutions.
