Answer: We can find the equation of a plane in point-normal form, which is given by:

Ax + By + Cz + D = 0

where (A, B, C) is the normal vector to the plane and (x, y, z) are the coordinates of any point on the plane, and D is a constant.

To find the normal vector, we can use the cross product of two vectors that lie on the plane. A convenient choice for these vectors is the direction vector of the line, which is given by:

v = <2-3, -1-4, 5-(-1)> = < -1, -5, 6 >

The normal vector to the plane is given by the cross product of the direction vector of the line and the vector pointing from any point on the line to the point (2,-3,1). Let's call this vector v2 = <2-3, -3-4, 1-(-1)> = < -1, -7, 2>

So the normal vector is given by:

n = v x v2 = ( -52 + 6-7)i + (6*-1 - -12)j + (-1-7 - -5*2)k = (14)i + (-7)j + (-11)k

Given that the point (2,-3,1) lies on the plane, we can substitute these values in the point-normal form equation:

A2 + B-3 + C*1 + D = 0

-142 + -7-3 + -11*1 + D = 0

-28 - 21 - 11 + D = 0

D = 58

So the equation of the plane is :

14x - 7y - 11z + 58 = 0

This is the equation that represents the plane that passes through (2,−3,1) and is normal to the line joining the points (3,4,−1) and (2,−1,5)

Answer:

x=1

Step-by-step explanation:

By looking at the equation we can see that the x intercept stays the same, so this is a vertical slope. in slope intercept form (y=mx+b) this looks like

x=b

and since we can see the two points x is always 1, we know that b is 1 so

x=1

Aha! It seems you are now working on absolute value.  If you don't know what that is, I'll give you a teeny lesson.  :)

|2 - 2| = 0
2 - 2 = 0
|-1 - 4| = 5
-1 - 4 = -5
|-100 - 1| = 101
-100 - 1 = -101

So basically the absolute value signs get rid of the negative number after the equation has been solved.  There is no such thing as "negative" in absolute value!

The distance between H and K is 9/4.  Remember, this line is flat, so you are not going to be getting any negative numbers as a result. It's absolute value.

K = 7/4, or 7/4 points away from 0.

------|--------------------------|----
     K    9/4 distance    H

7/4 + 9/4 = 16/4, 16/4 = 4.  H = 4 :)

Let me know if you need any examples.  Hope this helps!

Answer:

The second graph

Step by Step

First, note down the points given.

(-2, -1) etc

Then find the points on the graphs and see if the line of the graph goes through the point.

(-2,-1): both lines go through this point

(0,0) both lines go through this point

(2,1) only the second graph goes through this point

Therefore, the second graph is the correct answer. You can check the last point if you want to double check.

Answer:

I think it is 180° - n.

Step-by-step explanation:

Because the one side of a rectangle is 180° and n° is on the other side of angle m°. This means that angle m° + n° should equal 180° so we have to subtract n° from 180°

Answer: The product of -5 1/3 × 4.15 is -22 2/15.

Step-by-step explanation:

To calculate this, you can first convert the mixed number -5 1/3 to an improper fraction by multiplying the whole number part (-5) by the denominator of the fraction (3) and adding the numerator (1). This gives you -5 x 3 + 1 = -16 + 1 = -15/3.

Then you can multiply the two fractions: -15/3 × 4 15/100 = (-15/3) * (415/100) = -630/300 = -22 2/15

Therefore, the answer is a= -22 2/15.

[tex]\dfrac{8}{11} (n-10)=64[/tex]

Distribute:

[tex](\dfrac{8}{11} )(n)+(\dfrac{8}{11} )(-10)=64[/tex]

[tex]\dfrac{8}{11} n-\dfrac{80}{11} =64[/tex]

Subtract  [tex]\dfrac{80}{11}[/tex] from both sides:

[tex]\dfrac{8}{11} n-\dfrac{80}{11} +\dfrac{80}{11} =64+\dfrac{80}{11}[/tex]

[tex]\dfrac{8}{11} n=\dfrac{784}{11}[/tex]

Multiply both sides by [tex]\dfrac{11}{8}[/tex]:

[tex]\dfrac{11}{8} \times(\dfrac{8}{11} n)=\dfrac{11}{8} \times(\dfrac{784}{11} )[/tex]

[tex]\fbox{n = 98}[/tex]

Answer:

I found this. I am not sure tho!

To find the value of n in the equation 8/11(n - 10) = 64, you need to first get n by itself on one side of the equation.

To do this, you can start by isolating the n on one side by dividing both sides of the equation by 8/11. This gives you:

n - 10 = 64 * 11/8

Then, you can add 10 to both sides of the equation to get:

n = 64 * 11/8 + 10

You can then simplify this to find the value of n.

64 * 11/8 + 10 = 73

Therefore, n = 73.

The locations of each irrational number are the following:

√16 - Point a

√27 - Point b

√32 - Point c

Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.

Since, √16 is an irrational number that is also rational,

Since, 4² = 16

Then,  √ 16 must be point a.

Both √27 and √32 are greater than √25 = 5 and less than √36 = 6. Then, both are between 5 and 6.

Since, √27 < √32

Hence,  √27 must be point b and √32 must be point c.

Thus, The locations of each irrational number are the following:

√16 - Point a

√27 - Point b

√32 - Point c

Exponential Function: y = 2.5 million x 0.75

No, the show will not be canceled. The estimated number of viewers will remain above 2.5 million for all weeks, according to the graph.

The show will not be canceled here the estimated number of viewers will remain above 2.5 million for all weeks.

When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function. There usual form is specified below. They are written in several such equivalent forms.

We are given that television show will be canceled if the estimated number of viewers falls below 2.5 million by Week 10.

Let consider that x = Week and y = Viewers

Exponential Function:

y = 2.5 million x 0.75
