Answer:

{(-14,9),(4,-7),(-8,6)}.

Step-by-step explanation:

To find the inverse you just swap x and y.

So if (a,b) is a point on the relation then (b,a) is on it's inverse.

So the inverse of {(9, –14), (–7, 4), (6, –8)} is:

{(-14,9),(4,-7),(-8,6)}.

Montano1993 [528]

Let x be the total weekly sales.

His salary is $300/week + 1.8% (x), if he wants to earn $570, then:

300 + 1.8%(x) = 570
1.8%(x) = 270
0.018 (x) = 270

and x = 270/0.018 = $15,000

The Eiffel Tower in Paris, France. Lizbeth is 5.5 feet tall. She looks up at an angle of elevation of 72° to see the top from 31

garri49 [273]

Answer:

The height of the Eiffel Tower will be 318 feet.

Step-by-step explanation:

Please check the attached graph.

From the diagram, it is clear that Lizbeth is 5.5 ft tall, seeing the top from 318 feet away, making an angle of elevation to be 72⁰.

The diagram makes a right-angled triangle.

Given the angle = Ф = 72⁰

Adjacent = a = 5.5 ft

Opposite = b = 318 ft

Hypotenuse = the height of the Eiffel Tower = c ?

Pythagorean Theorem:

For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as:

$c=\sqrt{a^2+b^2}$

$a=5.5$

$b=318$

$c=\sqrt{5.5^2+318^2}$

$c=318$ feet

Therefore, the height of the Eiffel Tower will be 318 feet.

The mayor is trying to decide if she wants a triangular sitting area or a parallelogram sitting area. The formulas for area of a

docker41 [41]

The answer is The formula for the area of a parallelogram is A = bh, and the formula for area of a triangle is A = 1/2bh. Since a triangle is half of the area of a parallelogram with the same base and height, the only difference in the formula is 1/2.
