Answer:
The number in its standard form is
Step-by-step explanation:
The standard form of a number is just a simplified way of writing numbers {especially large ones} that has been agreed on by mathematicians all over the world.
To write a number in standard form we need to first of all check this:
1. Is the number greater than zero or not?
In our problem, 713.49 is clearly greater than zero so we can move on to the next step.
2. The next step is to make sure that we move the decimal point to a position where it will make the value of the number less than 10.
We can do this by moving the decimal point two times to the left. This makes the number 7.1349 which is less than 10.
3. The final step is to count the number of times that you moved the decimal point to make the number less than 10.
In our case, it is 2 times. We then use this number as the power.
Thus the answer will be
Answer:
The variation rate is 4.07 × 10⁻⁵ cm²/ºC
Step-by-step explanation:
The relationship of the change in length as a function of the temperature, which are given in this problem can be written by the expression for the area of a rectangle
a = L × W
Differentiating both sides,
=
= W + L
The values they give us are
= 1.1 × 10⁻⁵ cm/ºC
= 8.9 × 10⁻⁶ cm/ºC
W = 1.6 cm
L= 2.6 cm
Substituting the values and calculating
= (1.6 × 1.1 × 10⁻⁵) + (2.6 × 8.9 × 10⁻⁶)
= (1.76 × 10⁻⁵) + (2.31 × 10⁻⁵)
= 4.07 × 10⁻⁵ cm²/ºC
The variation rate is 4.07 × 10⁻⁵ cm²/ºC
we are given

Answer: Choice C) When you solve for the variable, you will end up with a false statement, like 0 = 2, for an equation with no solution. You will end up with a true statement, like 2 = 2 for an equation with infinitely many solutions.
For example, let's say we had the equation x = x+2. Subtracting x from both sides leads to 0 = 2 which is a false statement. No matter what we replace x with, the equation x = x+2 is always false. That's why we don't have any solutions here.
For an equation like x + 2 = x + 2, subtracting x from both sides leads to 2 = 2 which is always true. A true equation is one where the same number is on both sides. No matter what we replace x with, the equation will be true. Therefore, there are infinitely many solutions.
