Answer:

\sqrt{136}

Step-by-step explanation:

Formula for Pythagorean theorem: a^{2} +b^{2}  = c^{2}

Plug in:

6^{2}+10^2=x^2

Solve:

36 + 100 = x^{2}

136 = x^{2}

\sqrt{136} = x

The answer is \sqrt{136}.

Hope this helped.

F(x) = 4x^2+2x+6 what is the discriminant of f? How many distinct real number zeros does f have?
Sunny_sXe [5.5K]

Answer:

The discriminant of f is 92, and it has no real zeros

Step-by-step explanation:

The discriminant of a quadratic is b^2-4ac, where the quadratic is in the form ax^2+bx+c. The discriminant of this one is therefore:

2^2-4(4)(6)=4-96=-92

Since the square root of a negative number is imaginary, this quadratic has no real number zeros. Hope this helps!

What is the value of z?
VashaNatasha [74]

Answer:

z = 61

Step-by-step explanation:

The exterior angle is congruent (equal to) the sum of the 2 farthest angles from it, so you can set the equation like this:

z + z - 11 = z + 50

Add like terms, which would be the 2 "z's" on the left side:

2z - 11 = z + 50

Then subtract the z on the right side from both sides:

2z - 11 = z + 50

-z          -z

___________

z - 11 = 50

Add 11 to both sides:

z - 11 = 50

  + 11    +11

________

z = 61

Determine if the expression 9x^-2 is a polynomial or not. If it is a polynomial, state
Andrej [43]

Answer:

9x⁻²  is not a polynomial

Step-by-step explanation:

A polynomial function is a function that involves non-negative integer powers of x such as a quadratic, cubic etc.

A polynomial is a function written in the form of ;

f{x} =aₙxⁿ+aₙ₋₁xⁿ⁻¹+-------+a₂x²+a₁x+a₀

The degree of a polynomial is the highest power of x in the expression

9x⁻² ----in this case, the power is negative thus this is not a polynomial.
