1 = 4
a2 = -2(a1) - 1
a2 = -2(4) - 1
a2 = -9
a3 = -2(a2) - 1
a3 = -2(9) - 1
a3 = -19
Can you do a4 and a5 and answer?
For this translation, you need to replace every occurrence of "x" with "x-3", and every occurrence of "y" with "y+5".
Answer:
b
Step-by-step explanation:
Answer: $2250
Step-by-step explanation:
<u>Given information</u>
Dimension of the room = 20 feet × 15 feet
Cost of tiles = $7.50 / ft²
<u>Derived formula from the given information</u>
Total cost = Floor area × Cost of tiles
<u>Substitute values into the formula</u>
Total cost = Floor area × Cost of tiles
Total cost = (20 × 15) × (7.5)
<u>Simplify by multiplication</u>
Total cost = 300 × (7.5)

Hope this helps!! :)

The length of the altitude is 9.5 cm.
The altitude bisects the base of the equilateral triangle (this is because the two sides emerging from the vertex are equal). This gives us a right triangle with leg 5.5 and hypotenuse 11. We use the Pythagorean theorem:
5.5² + h² = 11²
30.25 + h² = 121
Subtract 30.25 from both sides:
30.25 + h² - 30.25 = 121 - 30.25
h² = 90.75
Take the square root of both sides:
√h² = √90.75
h = 9.5
