Answer:
2/3 2:3 2 to 3
Step-by-step explanation:
(15x3) feet ÷ 3 = (5x1) feet = 5 feet
33 feet x 5 feet=165 feet
165 feet ÷ 3 = 55 feet
55 feet÷(33 feet÷3)=55 feet ÷ 11 feet = 5 feet
Ans:
5 + 11 x 5 feet
The area of a circle is r^2*PI -> d = 10inch -> r = 5inch --> r^2 * PI = 5 * 5 * 3.14159 = 78.54 in^2
Answer:
The maximum height of the water balloon occurs at x = 0.
The water balloon is in the air for 2 s.
The maximum height of the water balloon is 64 ft.
Step-by-step explanation:
The water balloon rises above 64 ft before falling toward the ground.
I'm confused since it does start at a height of 64, but I think it meant that it started lower then went up, so I would say that wouldn't be true.
The water balloon hits the ground in 64 s
it hits the ground at 2 seconds
well, we know the tree is growing at a rate of 36 feet every 3 years, how many feet is that in 1 year alone? well, simply 36/3 = 12.
so the tree is growing 12 feet per year.
when it was first planted, it was 5 feet tall, and then after every year, we have to add 12 feet subsequently, let's do that
year 1 .......... 5 + 12(1)
year 2 .......... 5 + 12(2)
year 3 .......... 5 + 12(3)
year 4 .......... 5 + 12(4)
year 5 .......... 5 + 12(5)
year 6 .......... 5 + 12(6)
year 7 .......... 5 + 12(7)
year y .......... 5 + 12(y)
