A conjecture is a statement that you believe to be true, and that has be verified by your observations, not necessarily exhaustively. That is to say, your conjecture may not even be true, although you believe that it is.
If we denote by S the sum of the first 30 positive even numbers, we could make many conjectures, such as:
S is even
S is positive,
S=930
S is composite
.... etc.
Answer:
The average velocity of the rock would be 32 ft per second.
Step-by-step explanation:
A rock has been dropped from a height of 64 ft.
Height of the rock is determined after time 't' by the expression.
S(t) = -16t² + 64
Where 0 ≤ + ≤ 2
Total distance traveled by the rock in
2 seconds = 64 feet
Therefore average velocity = = 32 ft per second
The average velocity of the rock would be 32 ft per second.
The answer isn't clear ! can you resend the question so i can see the picture
Answer:
Step-by-step explanation:
12=3*2*2
15=5*3
12/15=4/3
8/10=4/5
no, they don't have the same value
30k + 70 = 20k + 80
30k - 20k = 80 - 70
10k = 10 / : 10
<u>k </u><u>=</u><u> </u><u>1</u>
