Would two successive 90° rotations counterclockwise about the origin result in the same image as a 180° rotation clockwise about the origin? Explain.

Answers

Answer 1

Answer:

When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). In other words, switch x and y and make y negative. When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative.

A scale drawing of an elephant shows the animal as 6 inches high and

10.8 inches long. The scale used for the drawing was 3 in..5 ft.

What are the height and length of the actual elephant?

Height:

feet

Length:

feet

Answers

Step-by-step explanation:

3 in to 5 ft

so, one basic unit in the drawing is in fact 3 inches.

how many base units fit into the numbers ? these factors need then to be multiplied with the base units of 5 ft for reality.

6 inches high

6 / 3 = 2

so, the elephant is 2 units high, which means in reality 2×5 = 10 ft high.

10.8 inches long

10.8 / 3 = 3.6

so, the elephant is 3.6 units long, which means in reality 3.6×5 = 18 ft long.

1. = 3xy + x - 2y - 4

2. = d^2(2c^3-8c^2d+3d^2)

Step-by-step explanation:

= 9x^2y^2 + 3x^2y - 6xy^2 - 12xy/3xy

First factor the top equation ….

= 3xy(3xy + x - 2y - 4)/3xy

If the top and the bottom both carry 3xy, you can cancel out both of them leaving you with ….

= 3xy + x - 2y - 4

= -16c^6d^6 + 64c^5d^7 - 24c^3d^8/-8c^3d^4

First factor the top equation ....

= -8c^3d^6(2c^3-8c^2d+3d^2)/-8c^3d^4

If the top and the bottom both carry -8c^3 you can cancel out both of them leaving you with ….

= d^6(2c^3-8c^2d+3d^2)/d^4

Apply the exponent rule with d^6 ....

= d^4d^2(2c^3-8c^2d+3d^2)/d^4

cancel out d^4 ....

= d^2(2c^3-8c^2d+3d^2)

A family on a trip budgets $1,338 for meals and gasoline. If the price of a meal for the family is $90 and if gasoline costs $2.80 per gallon, then how many gallons of gasoline can the family buy if they buy 13 meals

Answers

’creating a system linear equation, the number of possible gallons of gasoline that can be purchased is 60 gallons

Given the Parameters :

Total budget = 1338Meal cost = $90Gasoline cost = $2.80 per gallon Number of meals = 13 Number of gallons of gasoline = g

Hence, we have :

90(13) + 2.80g = 1338

1170 + 2.80g = 1338

2.80g = 1338 - 1170

2.80g = 168

g = 168/2.80

g = 60

Therefore, only 60 gallons of gasoline can be purchased.

Answer:

x=1.69 or x=-0.44

Step-by-step explanation:

1) multiply both sides by 4x-5 to give 3=x(4x-5)

expand this ------>3=4x^2 - 5x

2) bring the 3 on the other side by subtracting 3

4x^2 - 5x - 3 = 0

The value of x in the equation 3 / 4x - 5 = x is -20.

What is the equation?

An assertion that two mathematical expressions have equal values is known as an equation. An equation simply states that two things are equal. The equal to sign, or "=," is used to indicate it.

Given:

3 / 4x - 5 = x

Solve the above equation as shown below,

x = 3 / 4x - 5

x - 3 / 4 x = -5   (Transform the variable on the left side and constant on the right side)

4x - 3x / 4 = -5

x / 4 = -5

x = 4 × (-5)

x = -20

Thus, the value of x is -20.
