(x4)2

Answers

Answer 1
Answer: remember
(x^n)^m=x^(mn)

(x^4)^2=x^(4*2)=x^8
Answer 2
Answer: I strongly believe you meant (x^4)^2 as you're referring to polynomials.


(x^4)^2

= (x^4)*(x^4)

= (x*x*x*x)*(x*x*x*x)

= x^8

On the other hand, if you meant (x^4)2, then the answer is 2x^4

Hope this helps! :3

Write the equation in standard form 6x=y+3

Answers

The standard form of this equation is 6x - y = 3. Standard form is Ax + By = C, where A and B are the coefficients for x and y, and C is the number without a variable attached, or the constant. We just need to do a bit of algebra to get the equation in standard form.

6x = y + 3   Given
6x - y = 3   Subtract y from both sides

Hope this helps!
standard form  is ax+by=c
6x=y+3
lets move the y over to left side
minus y from both sides
6x-y=3
 

2x2 + 6x + 5 = 0 what are the real roots for the quadratic equation

2x^2 + 6x + 5 = 0

x= (-b+/- √(b^2 -4ac) )/(2a)

x= (-(6)+/- √((6)^2 -4(2)(5)) )/(2(2))

3. Determine whether or not AB is tangent to circle O. Show your work.​

Answers

The line AB touching the circle at point B in the considered diagram is not tangent to the circle O.

What is Pythagoras Theorem?

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

|AC|^2 = |AB|^2 + |BC|^2

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

How are radius and tangent to a circle related?

There is a theorem in mathematics that:

If there is a circle O with tangent line L intersecting the circle at point A, then the radius OA is perpendicular to the line L.

So, if AB is a tangent, then ∠ABO = 90° and therefore satisfies Pythagoras theorem.

Assuming AB is tangent, then ABO is right angled we should get:

H^2 = P^2 + B^2\n30^2 = 16^2 + 12^2\n900 = 256 + 144\n900= 500

This statement is false, and therefore, so as our assumption is false that ABis tangent to circle O. Thus, AB is not tangent to circle O.

(so it might be that even if AB looks like touching at one point the circle O, but AB might be intersecting the circle at two points, or not touching it at all)

Thus, the line AB touching the circle at point B in the considered diagram is not tangent to the circle O.
