Answer:
A. The function is always decreasing
Step-by-step explanation:
we read a graph from left to right, so we can always compare the increase/decrease of a function by seeing how an x value compares with an x value to the left
(I am aware that this paragraph is really confusing)
we can see that as x increases, from -∞ to 0,
y decreases in correspondence
and that as x increases, from 0 to ∞,
y decreases in correspondence also
So, even though the graph doesn't quite look like it, when x < 0; the function decreases, when x > 0; function decreases--so the function is always decreasing
hope this helps!! have a lovely day :)
The equation indicates that the center of the window is 12 feet from the ground and the distance the window spans 6 feet.
<h3>What is the general equation of a circle?</h3>
The equation of a circle is given by the formula,
where (a,b) is the coordinate of the center of the circle, and r is the radius of the circle.
According to the given equation, if we compare this equation with the general equation of the circle.
On observing this equation we will get that the value of (a,b) is (4,12).
Thus, The equation indicates that the center of the window is 12 feet from the ground
window span = diameter of circle
window span = 2r
= 2 × 3 (radius = 3)
= 6
Hence, The equation indicates that the center of the window is 12 feet from the ground and the distance the window spans 6 feet.

To find the area of a square with it's diagonal, there's actually a formula = (1/2)d², but here's how to do it if you don't have the formula:
The diagonal <em>c</em> separates the square into two of the same triangles. Therefore, we can apply Pythagorean Theorem
a²+b²=c² ← Since this is a square, a=b is a must
a²+a²=c² ← Combine like terms, and plug 26 in for c
2a²= 26² ← 26²=676, then divide 2 on both sides
a²= 676/2
a²=338 ← We can just stop here! Since <em>a </em>is a side of the square, therefore the area of a square = a²
Answer: 338 units²
7 = r^1/2 is the same as saying 7 = square root of r. So, to get rid of the square root sign on the r, you need to square it, and when you do something to one side of the equation, you have to do the same to the other side. So after squaring both sides, you get 49 = r.
Answer: $357 is more amount budgeted for food increase.
Explanation:
Since we have given that
Number of people according to the budget = 150
Cost of food per person= $4.25
Total cost of food is given by
If the number of guests attending the opening was 56% more than expected,
So, number of guests now is given by
Total cost of food is given by
Difference between them is given by
Hence, $357 is more amount budgeted for food increase.
