Answer:
It’s A
Step-by-step explanation:
The area (A) of a circle with radius r is given by
... A = π·r²
For a radius of 7 ft, the area is
... A = π·(7 ft)² = 49π ft² ≈ 154 ft²
The area of the bottom of a circular tent with radius 7 ft is about 154 ft².
Answer:
Correct answer: B
Step-by-step explanation:
Syntax: in piecewise functions such as the one attached, the "if:" section shows the domain, or x-axis values which that function pertains to.
In the graph, you can see that the graph is defined for (not-including 1 because there is an open hole there, indicating it is not part of the domain), and .
Now that we know the domain, we can attach it to the graphs that lie on those domains.
We see that the leftmost line appears to have a positive slope and a negative y-intercept, and that the second line should have a positive y-intercept and a negative slope.
At this point, you can just start crossing off answers that don't meet this criteria.
