Answer:
100feet
Step-by-step explanation:
Given the height reached by a dolphin expressed by the equation is h = -16t^2 + 80t. At maximum height, the velocity is zero, hence;
v(t) = dh/dt = -32t + 80
0 = -32t + 80
32t = 80
t = 80/32
t = 2.5secs
Substitute t = 2.5 into the height formula h = -16t^2 + 80t
h = -16(2.5)^2 + 80(2.5)
h = -100+200
h = 100feet
Hence the maximum height the dolphin jumps is 100feet
Step-by-step explanation: First you put two pencil then add another two pencil. Now how much do you have in total, the answer is 4.
Answer: 8 batches
explanation: 5 1/3 divided by 2/3 equals 8. To find out how many batches were made, you need to divide the total amount used by the amount needed for one batch.
Hello!
3,486 / 2 = n
n = 1743
work:
you simply divide 3,486 by 2
if you divide each number by two (right to left)
6 / 2 = 3
8 / 2 = 4
4 / 2 = 2
3 / 2 = 1.5
since there is a decimal in this, multiply it by 10 and add it to the number before. this number will go on the right side of the total
1.5 * 10 =15
15 + 2 = 17
17 4 3 are the final numbers in order. put them together and you have 1743
