Answer:

176.63 cubic in. =A

Step-by-step explanation:

The area of a circle can be found by using the equation $\pi r^{2}$ =A. The problem gives us the diameter, but we need the radius. To find the radius divide the diameter by 2, so raduis= 7.5 in.

$\pi r^{2}$ =A

(3.14)( $7.5^{2}$ )=A

(3.14)(56.25)=A

176.63 cubic in. =A

Find the equation for the plane that contains the line x=−1+3t , y=1+2t, z=2+4t and is perpendicular to the plane containing the

Ivan

Let $L$ be the line given by the vector equation

$(-1,1,2) + \lambda(3,2,4) \ , \lambda \in \mathbb{R}$ .

First, we use the director vectors of the lines L1 and L2 to get the

vector equation of the plane containing them, which we denote by $\Pi_1$ . This is,

$\\\\\Pi_1 : (1,-1,5) + \alpha (2,-1,6) + \beta (1,1,-3) \ , \alpha, \beta \in \mathbb{R}\\\\\\$

We observe that $\vec{N} = (2,-1,6)\times(1,1,-3) = (-3,12,3) \ne (0,0,0)$ . Therefore, the vector equation of $\Pi_1$ defines a plane and $\vec{N}$ is a normal vector to $\Pi_1.$

Finally, the vector equation for the wanted plane, which we denote by $\Pi$ , is

$\Pi : (-1,1,2) + r(3,2,4) + s(-3,12,3), r,s \in \mathbb{R} \ .$

Thus, if $s = 0$ , then $L \subset \Pi$ and since $\vec{N}$ is parallel to $\Pi$ , then it is perpendicular to $\Pi_1$ .

Answer:

Yes 4:3

Step-by-step explanation:

To solve this, take the the inside number and subtract in from the outside number. Look at the question very carefully for this part...

Since it says the ratio of the outside number to the inside number, take that number and see how many times it can fit into the outside number. In this case, it is 4, and than for the inside number, it is 3.

Now do the same for the other measurement and see if it has the same ratio, and if it does, that is the answer.

(2x+30y)=(12x+17)<br> Find x

Hunter-Best [27]

2x+30y=12x+17
30y=10x+17
y=(10/30)x+(17/30)

x-intercept:
0=(10/30)x+(17/30)
-17/30=(10/30)x
-17/10=x
