Answer:
Step-by-step explanation:
The formula for determining the the area of a sector is expressed as
Area of Sector = θ/360 × πr²
Where
θ represents the central angle.
π is a constant whose value is 3.14
r represents the radius of the circle.
From the information given,
The central angle is π/7 radian. Converting to degrees, it becomes
π/7 × 180/π = 180/7 = 25.714 degrees.
Area of sector = 77 square meters
Therefore
77 = 25.714/360 × 3.14 × r²
77 = 0.2243r²
r² = 77/0.2243 = 343.29
r = √343.29 = 18.53 meters
Ohhhh, I did this stuff last year. i wish i can remember... but your best bet is A because that angle is super small so A would be best. Hope I helped brainliest plz
Answer:
See explanation
Step-by-step explanation:
You have not provided the options to help us give you a specific answer.
If a quadratic function is written in the form

Then (h,k) is the vertex, and 'a' is a constant.
For instance

has vertex at (2,3).
Also, an absolute function in the form

has vertex at (h,k).
This means

also has vertex at (1,3).
I hope this explanation is helpful.

Step-by-step explanation:
I used a graphing program to graph the given system. I also graphed the points given.
Options B's choice lies in the double shaded area, so it would be a solution to the system.
See the graph attached!
Hope this helps you!
Find a common denominator...
1/5 = 7/35
7/35 = 7/35
6/25 = ... can't have 35 as a denominator. Not equivalent.
