Step-by-step explanation:
Answer:
δhsoln will be close to zero.
Step-by-step explanation:
In calculus, the symbol d represents a large or significant increment in a value. For example, say the change in the volume of a liquid in a tank depends upon the change of the height h.
The above statement can be written like this:
dV/dh
This means that the volume of the tank (V) depends with a significant change in the height of the liquid (h).
It is also possible to compute small changes in physical quantities. The symbol δ simply presents a small increment or small change. Using the same expression above, if a very large tank was to have a very very small leak, the change would be: δV/δh
In other words, the change in the volume will be almost negligible and will be close to zero.
Equation B: 2x + 4z = 1
Which of the following is a possible step used in eliminating the z-term?
Multiply equation B by 4.
Multiply equation A by 2.
Multiply equation A by −4.
Multiply equation B by 2.
If you would like to eliminate the z-term, you can do this using the following steps:
x + z = 6 /*(-4)
2x + 4z = 1
_____________
-4x -4z = -24
2x + 4z = 1
_____________
-4x + 2x = -24 + 1
-2x = -23
x = 23/2
The correct result would be x + z = 6 /*(-4); multiply equation A by -4.
A possible step which can be used in eliminating the z-term is: C. multiply equation A by -4.
Given the following data:
A set of equations is also referred to as a system of equations and it can be defined an algebraic equation that has only two (2) variables, which can be solved simultaneously.
In order to eliminate the z-term, we would subtract the second equation from 4 times the first equation:
Multiplying the first equation by 4, we have:
4[x + z = 6] = 4x + 4z = 24
Subtracting the two equations, we have:
[4x + 4z - 24 - 2x - 4z - (-1)] = 0
2x - 23 = 0
2x = 23
x = 23/2
x = 11.5.
In conclusion, a possible step which can be used in eliminating the z-term is to multiply equation A by -4.

Answer:
Step-by-step explanation:
x + 4 + 6x - 47 = 90
7x - 43 = 90
7x = 133
x = 19
S = 19 + 4 = 23
R = 6(19) - 47 = 114 - 47 = 67
Two different websites offer the same watch for sale. The watch costs $45 on both sites. The site, Watches for Less charges a shipping fee of 4% of the cost of the watch. The site, Tick Tock charges 2.5% of the cost of the watch for shipping. How much less will the total cost of the watch be if purchased from Tick Tock?
Round your answer to the hundredths place.
Answer:
$0.67
Step-by-step explanation:
Cost of Watch on both sites=$45
Watches for Less charges a shipping fee of 4% of the cost of the watch.
Therefore, total cost of the watch at Watches for Less
=$45+(4% of 45)=45+(0.04 X 45)
=45+1.8
=$46.8
Tick Tock charges 2.5% of the cost of the watch for shipping.
Therefore, total cost of the watch at Tick Tock
=$45+(2.5% of 45)=(45+0.025X45)
=45+1.13
=$46.13
Difference In Cost
Cost at Watches for Less-Cost at Tick Tock
=$46.8-46.13
=$0.67
The total cost of the watch will be $0.67 less if purchased from Tick Tock
