Find the area of a plane figure bounded by lines

natulia [17]

Answer: 4.5

<u>Step-by-step explanation:</u>

First, find the points of intersection by solving the system.

y = x² + 2x + 4

y = x + 6

Solve by substitution:

x² + 2x + 4 = x + 6 ⇒ x² + x - 2 = 0 ⇒ (x + 2)(x - 1) = 0 ⇒ x = -2, x = 1

Now, integrate from x = -2 to x = 1

$\int\limits^1_2 {(x+6)-(x^{2}+2x+4) } \,$ <em>the bottom of the integral is -2 </em>

= $\int\limits^1_2 {x+6-x^{2}-2x-4 } \,$

= $\int\limits^1_2 {-x^{2}-x+2 } \,$

= $\frac{-x^{3}}{3} - \frac{x^{2}}{2}+2x\int\limits^1_2 {} \,$

= $(\frac{-1^{3}}{3} - \frac{1^{2}}{2}+2(1)) - (\frac{-(-2)^{3}}{3} - \frac{(-2)^{2}}{2}+2(-2))$

= $(\frac{-1}{3} - \frac{1}{2} +2) - (\frac{8}{3} -\frac{4}{2} -4)$

= $\frac{-9}{3} + \frac{3}{2} +6$

= -3 + 1.5 + 6

= 4.5

If i am dtiving 8 miles at 55 miles per hour how long willnit take

anyanavicka [17]

Answer:

It takes 0.145 hours

Step-by-step explanation:

Given:

Distance = 8 miles

Speed = 55 miles per hour

To Find:

Time taken = ?

Solution:

The time taken for an object to travel a particular distance with a average speed can be found by

$\text{Time Taken} = \frac{distance}{ speed}$

Now Substituting the given values , we get

$\text{Time Taken} = \frac{8}{55}$

$\text{Time Taken} = 0.145$

Time taken will be 0.145 hours

Name a point that is not coplanar with points A, B, and C.

boyakko [2]

Points are coplanar if they are located on the same plane. A plane is one of the undefined terms in geometry. It is described as a flat surface in a two-dimensional area. If you look at the given figure, find points that are not included in the shaded plane of points A, B and C. That would be point M or point D.
