Danielle's mistake was that he did not add the middle like-wise terms of 2x² and x² in step 3.
<h3>What are Arithmetic operations?</h3>
Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Subtract x³ - 2x² from x² - 6
Danielle's mistake
⇒ (x³ - 2x²) - (x² - 6)
⇒ x³ - 2x² - x² + 6
⇒ x³ - 2x² + 6
He wrote 2x² instead of 3x²,
Danielle's mistake was that he did not add the middle like-wise terms of 2x² and x² in step 3.
Here is the Correct work as:
⇒ (x³ - 2x²) - (x² - 6)
⇒ x³ - 2x² - x² + 6
⇒ x³ - 3x² + 6

Well how many 12's are in 24 (forget the negative sing for a moment). Two right? Well that means multiply 4 by 2 and get 8, but where does that negative sign go? Just add it! It makes it so much easier taking it away and then putting it back. That is a trick for this problem. y=-8 while x=-24 Hoped I helped!

Answer:
Part 1) The exact value of the arc length is \frac{25}{6}\pi \ in
Part 2) The approximate value of the arc length is 13.1\ in
Step-by-step explanation:
ind the circumference of the circle
The circumference of a circle is equal to
C=2\pi r
we have
r=5\ in
substitute
C=2\pi (5)
C=10\pi\ in
step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion
\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in
Find the approximate value of the arc length
To find the approximate value, assume
\pi =3.14
substitute
\frac{25}{6}(3.14)=13.1\ in
