Part A Simplify:

Answer is - 12b + 6c + 18

Part B

Answer is (D)

Factor/simplify
- 12b + 6c + 18

6(- 2b + c + 3)
= (6)(- 2b + c + 3)
= (6)(- 2b ) + (6)(c) + (6)(3)
= - 12b + 6c + 18

therefore,- 12b + 6c + 18; Factored in GCF is 6(-2b + c + 3)

- 12b + 6c + 18
reorder the terms
18 + 12b + 6c

Factor out the GCF " 6"
6(3 + 2b + c)

Final Result:
6(3 + 2b + c)

Use the arc length formula to find the length of the curve y = 2 − x2 , 0 ≤ x ≤ 1. Check your answer by noting that the curve is

Lina20 [59]

By using the arc length formula, we will see that the length of the curve is L = 1.48

<h3>How to use the arc length formula?</h3>

Here we have the curve:

y = 2 - x^2 with 0 ≤ x ≤ 1

And we want to find the length of the curve.

The arc length formula for a curve y in the interval [x₁, x₂] is given by:

$L =\int\limits^{x_2}_{x_1} {\sqrt{1 + \frac{dy}{dx}^2} } } \, dx$

For our curve, we have:

dy/dx = -2x

And the interval is [0, 1]

Replacing that we get:

$L =\int\limits^{1}_{0} {\sqrt{1 + (-2x)^2} } } \, dx\\\\L \int\limits^{1}_{0} {\sqrt{1 + 4x^2} } } \, dx\\$

This integral is not trivial, using a table you can see that this is equal to:

$L = (\frac{Arsinh(2x)}{4} + \frac{x*\sqrt{4x^2 + 1} }{2})$

evaluated from x = 1 to x = 0, when we do that, we will get:

$L = \frac{Arsinh(2) + 2*\sqrt{5} }{4} = 1.48$

That is the length of the curve.

I don't know how to put this answer in.

Answer:

$i \times j = k \\ j \times k = i \: and \: k \times i = j \\ \\ j \times i= - k \\ k \times j = - i \\ i \times k = - j \\ \\ (i - k) \times (k - j) = \\ i \times k - (i \times j) - \\ (k \times k) + (k \times j) \\ note \\ \: i \times i = j \times j = k \times k = 0$

Starting at home, Omar traveled uphill to the gift store for 30 minutes at just 10 mph. He then traveled back home along the sam

hichkok12 [17]

I guess you want to find the average speed for the whole journey

average speed = distance travelled / time

the distance from home to the shop = speed * time = 0.5*10 = 5 miles

time for travelling back = distance / speed = 5/30 = 1/6 hours

average speed for whole journey = 10 / (1/2 + 1/6) = 10 * 3 / 2 = 15 mph
