Answer:
-25 and 4
Step-by-step explanation:
-25×4=-100 and -25+4=-21
Using equation of motion.
S = ut + (1/2)gt²
Where S = Height, t = time, g = acceleration due to gravity = 9.8 m/s²
time, t = 8 seconds
Since it was dropped from height, initial velocity, u = 0
S = 0*t + (1/2)gt²
S = (1/2)gt²
S = (1/2)*9.8*8² = 4.9 * 8 * 8 = 313.6
Therefore the ledge is 313.6 m tall.
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x + 1 ← is in slope- intercept form
with c = 1, thus
(0, 1) ← is the y- intercept
Answer:
C.
D.

Step-by-step explanation:
Formula for volume of a cuboid 
. where l is the length, w is the width and h is the height.
Using this equation we can answer the question by using the values given.
From the list of answers, we can compare each one to the answer we got and see if they match up.
The answers that match up are:
C. 
- it is exactly like the answer we got.
D. 
- if we simplify the brackets, it is exactly like the answer we got.
E. 
- once again, if we simplify the brackets it is like the answer we got.
None of the other answers are correct as they do not match up with the answer we got.
