To determine x intercept, put y=0

<span>x^4 - 10x^2 + 9  = 0
</span>
<span>x^4 - 9x^2  - x^2 + 9 = 0

x^2(x^2 - 9) - 1(</span><span>x^2 - 9) = 0

(</span><span>x^2 - 9)(x^2-1) =0

x^2 - 9 = 0
⇒ x^2 = 9
⇒x = +3, -3

x^2 - 1 = 0
x^2 = 1
x = +1, -1

X intercepts are -3, -1, 1, 3

Considering the expression x/2 + y2. Which statements are true?Mark all that apply.
Svet_ta [14]

Answer:

  D.  8/2 +(-10)² = 104

Step-by-step explanation:

To find which statements are true, evaluate the expression for the given variable values. You do this by putting the numbers in place of the respective variables, then doing the arithmetic.

The respective expression values are ...

  A 83 ≠ 37 . . . . (4/2) +9² = 2 +81 = 83

  B 31 ≠ 61

  C 52 ≠ 61

  D 104 =104 . . . . true statement

__

I find it less tedious to write a function into a calculator or spreadsheet and let it do the repetitive math. Examples of the calculation are shown above.

Amir stands on a balcony and throws a ball to his dog, who is at ground level. The ball's height (in meters above the ground), x
Y_Kistochka [10]
When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.

0=-(x-2)^{2}+16 \\  \\ &#10;(x-2)^{2}=16 \\  \\ &#10;x-2= \sqrt{16} \\  \\ &#10;x-2=4 \\  \\ &#10;x=6

This means the ball will hit the ground 6 seconds after Amir threw it
