Answer:
52
Step-by-step explanation:
Answer:
a=sqrt(d)-b, a=-sqrt(d)-b
Step-by-step explanation:
(a+b)^2=d
(a+b)=sqrt(d)
a+b=sqrt(d), a+b=-sqrt(d)
a=sqrt(d)-b, a=-sqrt(d)-b
You cannot add row 2 to column 3 because they have different dimensions. You can do any of the other operations, but the only one that makes any sort of sense is ...
Multiply row 2 by -1 and add it to row 3
_____
It makes no sense to multiply a row by zero. That makes the entire row zero and makes the matrix useless for finding any sort of solution.
You can switch columns, but that doesn't get you any closer to a solution here.
If I were trying to find a solution, I might
switch rows 1 and 2
multiply the new row 1 by -3 and add it to the new row 2
multiply the new row 1 by 2 and add it to row 3
This sequence of operations will make the first column [1 0 0], reducing the problem to 2×2 from 3×3.
Answer:
The diver will be in free fall for 
seconds.
Step-by-step explanation:
The distance in feet, that an object falls in t seconds is given by the function 
.
Now, given that the height is 4800 feet and we have to calculate the number of seconds the diver was in a free fall.
Therefore, 
⇒ 
⇒ 
seconds.
Therefore, the diver will be in free fall for seconds. (Answer)
Answer: False.
Step-by-step explanation:
48 is not a common factor of 4 and 6
4 and 6 only share 2 factor: 1 and 2
Factors in 4: 1, 2, 4
Factors in 6: 1, 2, 3, 6
