<span>Depending on the equation there can be three possible cases: 1- There can be 1 specific solution for the variable: 2x+4= 3 where x= -1/2 2- there can be an infinite amount of solutions: 2x+x-2=3x-3+1 where x=x 3- there can be no answer: 3+2x-x=5-3x+4x where the solution doesn't exist</span>

The vertex of the parabola below is at the point (4, -1). Which of the equations below could be the one for this parabola?
kari74 [83]
One possible equation for this quadratic would be 

y=(x-4)²-1.  This is vertex form:  y=a(x-h)²+k, where (h, k) is the vertex.

However, this is not the only possible equation.  There could be multiple values for a, in front of the parentheses, that we don't know about from the information we are given.

We can also write this equation in standard form (y=ax²+bx+c).  First write the squared binomial as the product of two binomials:
y=(x-4)(x-4)-1

Multiply the binomials:
y=x*x-4*x-4*x-4(-4)-1
 = x²-4x-4x--16-1
 = x²-8x+16-1
 = x²-8x+15

Again, this would change depending on what the value of a is in the functoin.

What is the shape of the cross-section formed when a plane containing line ac and line eh intersects this cube? what is the area
ioda

The shape of the cross-section formed when a plane containing line AC and line EH intersects the cube is a rectangle.

<h3>What is the explanation for the submission above?</h3>

Note that the Area of the cross-section = 16 sqrt(2) = 22.63 sq. units. The justification for this is the properties of the Cubes.

  • The top face ABCD is parallel and congruent to the bottom face EFGH....(A)
  • Also, sides AE and CH are perpendicular to faces ABCD and EFGH ....(B)

Mathematically, we can righty state that Diagonals AC and EH are congruent .....(C)

Given the justification by (A), congruent top and bottom faces, let us look at the cross-section ACHE.

AC is congruent and parallel to  EH   (A) & (C)

EA & HC are perpendicular to AC      (B)

Hence, the quadrilateral ACHE is a rectangle.

Step 2

Length of diagonal AC = sqrt(4^2+4^2) = 4 sqrt(2)  Pythagoras theorem.

AE = CH = DG = 4    We state this because the of the properties of cube, all sides equal;

Hence, the Area of ACHE = 4* 4sqrt(2) = 16 sqrt(2)

= 22.63 sq. units

Show work. Find the mean and standard deviation of the data. Round to the nearest tenth. 20,16,18,14,9,20,16
postnew [5]
20+16+18+14+9+20+16=113
113÷7=16.14285714
after rounded the answer would be 16.
hope that's correct.
