$99.50 * 0.95 = $94.53
$99.50 - $94.53 = $4.97
Answer:
y = -(1/2)x - 3
Step-by-step explanation:
it is the function for the two points.
Answer:
a = 12
Step-by-step explanation:
<u>Pythagoras’ Theorem</u>
a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
From inspection of the triangle:
- leg a = a
- leg b = 9
- hypotenuse c = 15
Substituting these values into the formula and solving for b:
⇒ a² + 9² = 15²
⇒ a² + 81 = 225
Subtract 81 from both sides:
⇒ a² + 81 - 81 = 225 - 81
⇒ a² = 144
Square root both sides:
⇒ √(a²) = √(144)
⇒ a = 12
For side length s, the area of a square is given by
... A = s²
Then the side length can be found to be
... s = √A = √(506.25 ft²) = 22.5 ft
The perimeter is the sum of the lengths of the four equal sides.
... P = 4s = 4·(22.5 ft) = 90 ft
Stevan will need 90 ft of fence to complete the job.
Answer:
(4, - 5 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 270°
a point (x, y ) → (- y, x ) , thus
(- 5, - 4 ) → (4, - 5 )
