There are 4 colors, White ,Green , Red and Orange. And there is a spinner which has 4 sections.
To see how many there are visually you could write out the outcomes.
-White and section 1
-White and Section 2
-White and Section 3
-White and Section 4
-Green and Section 1
-Green and section 2
-Green and Section 3
-Green and Section 4
-Red and Section 1
Red and Section 2
Red and Section 3
Red and Section 4
Orange and Section 1
Orange and Section 2
Orange and Section 3
Orange and Section 4
When you count them up it equals 16 outcomes.
FAST WAY: just multiply the colors and spinner sections, which is also 16.
$32.072 ≈ $32.07
20% of $38 is equal to $7.60
$38 - $7.60 = $30.40
5.5% of $30.40 = 1.672
$30.40 + $1.672 = $32.072
Answer:
The vertex is at (-4, -18) (Fourth answer choice)
Step-by-step explanation:
The standard vertex equation of a parabola is f(x) = (x - h)^2 + k.
"Completing the square" is one of the faster and better ways of determining the vertex:
f(x) = x^2 + 8x - 2 => f(x) = x^2 + 8x + 16 - 16 - 2 => (x + 4)^2 - 18. Comparing this to (x - h)^2 + k, we see that h = -4 and k = -18. The vertex is at (-4, -18).
X is greater than or equal to 1.5
