Step-by-step explanation:
f(x) = -4x^2+24x-29
= -4(x^2-6x)-29
= -4(x-3)^2 -4(-9) -29
= -4(x-3)^2 +36-29
= -4(x-3)^2 +7
maximum height = 7m
If A = {2, 3, 4, 5} B = {4, 5, 6, 7} C = {6, 7, 8, 9} D = {8, 9, 10, 11}, find (A ∪ B) ∪ C

Answer:
Total ft climbed= 3,011.36
Step-by-step explanation:
<u>Giving the following information:</u>
Total ft= 6,300
Climbing rate= 15% of the remaining height per day
<u>Total ft climbed per day:</u>
Day 1= 6,300*0.15= 945
Day 2= (6,300 - 945)*0.15= 803.25
Day 3= (5,355 - 803.25)*0.15= 682.76
Day 4= (4,551.75 - 682.76)*0.15= 580.35
Total ft climbed= 3,011.36
Answer:
4x-y=-9
Step-by-step explanation:
- Key -
Black tiles = x
Purple tiles = x+50
Yellow tiles = 5x
-
Total = x + x+50 + 5x = 400
⇒ 7x + 50 = 400
⇒ 7x = 400-50 = 350
⇒ x = 350/7
⇒ x = 50
Black tiles = 50
Purple tiles = 50+50 = 100
Yellow tiles = 5 x 50 = 250
