Answer:
1 seconds after being thrown, the stone reaches its max height
Step-by-step explanation:
The parabolic (quadratic) equation is:
Lets expand this in the form , so we have:
We can say the values of a,b, and c, now to be:
a = -5
b = 10
c = 40
The number of seconds at which the max would occur is given by the point, x, at:
We know a and b, let's find the seconds, x,
Hence,
1 seconds after being thrown, the stone reach its max height
Answer:
My answer is B and C
Step-by-step explanation:
If you put B in the same dimension, all the sides are equal. Similarly for part C, since the sides are the same, the base of the triangles are the same lengtg
Answer:
7
Step-by-step explanation:
4m - 5 = 4 * 3 - 5 = 12 - 5 = 7
Answer:
32inches
Step-by-step explanation:
Initial width = 3inches
Initial length = 5inches
Final width = 2× 3inches = 6inches
Final length = 2× 5inches = 10inches
Perimeter = 2×( finallength + finalwidth) = 2×(10inches + 6inches) = 2×(16inches) = 32inches
