The graph of the function f(x) = (x + 2)(x − 4) is shown.Which describes all of the values for which the graph is negative and increasing?
all real values of x where x < −2
all real values of x where −2 < x < 4
all real values of x where 1 < x < 4
all real values of x where x < 0

It would be increasing from the vertex to the zero,4.
So the answer would be 1 < x < 4
The values for which the graph is negative and increasing are all real values of x where 1 < x < 4.
Given
The graph of function;
What is a graph?
A graph goes from being negative to positive (or the other way around) by passing through the x-axis. in other words when f(x) = 0.
Then,
For increasing and decreasing for anything other than a quadratic and linear function you need calculus.
The function is negative below the zeros which would be from -2 to 4.
It would be increasing from the vertex to zero,4.
Hence, the values for which the graph is negative and increasing are all real values of x where 1 < x < 4.

of the result is the same every time. It only changes if you leave out what
you picked the first time, because then the total number of possibilities is
different.
With this reasoning, they might say that iii. is dependent because you
don't replace what you draw the first time. I'm not comfortable with that.
Sure, you don't replace the first number you picked, but how many odd
numbers are left ? Still an infinite number.
So I think iii. is the answer they want here, but I don't think any of the
choices is really dependent.
2). By the same reasoning, i. and ii. are independent. The coins have
no memory. They don't remember what happened last time.
3). The probability of any result is
(number of successes)/(number of possibilities).
Total number of possibilities each time is 8.
Probability of an even number (2, 4, 6, or 8) the first time = 4/8 = 0.5
Probability of an odd number (1, 3, 5, or 7) the second time = 4/8 = 0.5
Probability of an 8 the third time = 1/8 = 0.125 .
Probability of all 3 events = (0.5) x (0.5) x (0.125) = 0.03125 (3.125%)

Final answer:
The total cost of Dara's purchases was $38.07. Upon subtracting this amount from her initial $50, she is left with $11.93 change.
Explanation:
To solve the problem, you need to add up how much Dara spends and subtract that from $50. First, add the cost of the sandals, shorts, and hat together:
- $13.02 for sandals
- $9.85 for shorts
- $15.20 for the hat
When you add these three amounts together, you get $38.07. So, Dara has spent $38.07 in total. Now, subtract that amount from $50:
$50.00 - $38.07 = $11.93
This means Dara should get back $11.93 in change.

Circumference = π d
d = diameter is twice the radius
C = 3.14 * 2 * 18ft
C = 3.14 * 36 ft
C = 113.04 ft
However, with the choices we only need to get the diameter as the longest distance from one end of the circular patio to the other.
d = 2 r
d = 2 * 18ft
d = 36 ft. CHOICE C.
'longest distance' could mean Diameter.
r*2= d
radius = 18 feet
18*2 = 36
d = 36
The answer would be: 36 ft
