Answer:
Option (2). 14 m
Step-by-step explanation:
Formula to get the area of a circle 'A' =
where r = radius of the circle
Given in the question,
Area of the circle = 153.86 square meters
By putting the values in the formula,
153.86 = πr²
r =
r =
r = 7 meters
Diameter of circle = 2 × (radius of the circle)
= 2 × 7
= 14 meters
Therefore, diameter of the circle is 14 meters.
Option (2) is the answer.
Answer:
24 Months
Step-by-step explanation:
First you need to know how many books Ronnie read each month. 30 ÷ 15 = 2
Now you know Ronnie reads 2 books every month for 15 months.
So just take 48 ÷ 2 = 24
You take 48 because that's the total number of books so far and you divide it by 2, because he reads 2 books every month. That gives you a total of 24 months he has been with his book club.
F(x) = f(-2.75)
When x = -2.75, y = D. -1 according to the graph

Answer:
7: B, 8: A
Step-by-step explanation:
7. The domain of a function is the set of all of the values of x that are in it. In this case, we are given a series of points, so the domain of the function will be the set of x-coordinates of the points. The x-coordinate of a point is the first coordinate in the ordered pair representing the point. For example, in (0, 1), the x-coordinate is 0.
Applying that here, the x-coordinates of the points are 8, 5, 9, and 6, or 5, 6, 8, 9 in ascending order. Therefore, the domain of the function is {5, 6, 8, 9}, or option B.
8. In a system of coordinates, an abscissa is simply an x-coordinate (option A). For example, in our previous example point, (0, 1), the abscissa would be 0, because the point's x-coordinate is 0. Hope this helps!
