Ceiling = 5 x 4 = 20 m²
The 4 walls = ( 5 + 5 + 4 + 4) x 3 = 18 x 3 = 54 m²
Total area = 20 + 54 = 74 m²
1 m² = $7.50
74 m² = $7.50 x 74 = $555.
Answer: It will cost $444 to white-wash the walls and the ceiling.
Answer:
Should be the bottom one
Step-by-step explanation:
You can find this by counting. It is the only one with 12 units.
Answer:
Step-by-step explanation:
(h, k) = (4, 8)
(y - k) = a(x - h)²
(y - 8) = a(x - 4)²
y = a(x - 4)² + 8
plug in one of the x intercepts (or any other known point on the curve)
0 = a(2 - 4)² + 8
0 = a(4) + 8
a = -2
y = -2(x - 4)² + 8 fourth option.
For this, simply use the rules of logs:
- Adding logs of the same base (which is 7 here) is the same as multiplying
-Subtracting logs of the same base is dividing
So the single log would be:
log₇(x*y/z) which is the same as
log₇(xy/z)
5>x because you can subtract 5 from both sides and 3x from both sides
