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.
Answer:
The length of the side of a square is
Step-by-step explanation:
Area of square =
We need to find length of the side
The formula used will be:
Putting value of area of square, we can find length
So, length of the side of a square is
That is false, they also needed a compass. (apex)
Answer:
a) P = 6x + 13//
b) i) x = 5//
ii) 9//
Step-by-step explanation:
a) P = 2(x+2) + 2(2x-1) + 3 + 8 m
= 2x+4 + 4x-2 + 3 + 8
= 6x + 13//
b) i) P = 43 m
43 = 6x + 13
43-13 = 6x
<u>3</u><u>0</u> = <u>6</u><u>x</u><u> </u>
6 6
x = 5//
ii) longest side = (2x-1) m
2 × 5 - 1
10-1 = 9//
