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:
Yes
Step-by-step explanation:
In the first equation, sub in (-3x/2) for y:
3x+4y=12
3x+4(-3x/2)=12
3x-(12x/2)=12
3x-6x=12
-3x=12
x=-4
y=-3x/2
y=-3(-4)/2
y=12/2
y=6
Since x=-4 and y=6, (-4,6) is a solution.
Answer:
-6 < x ≤ 6
Step-by-step explanation:
A statement correctly compares functions f and g is that: C. they have the same end behavior as x approaches -∞ but different end behavior as x approaches ∞.
<h3>What is a function?</h3>
A function can be defined as a mathematical expression that defines and represents the relationship between two or more variable, which is typically modelled as input (x-values) and output (y-values).
<h3>The types of function.</h3>
In Mathematics, there are different types of functions and these include the following;
- Piece-wise defined function.
Function g is represented by the following table and a line representing these data is plotted in the graph that is shown in the image attached below.
x -1 0 1 2 3 4
g(x) 24 6 0 -2
Based on the line, we can logically deduce the following points:
- y-intercept approaches -2.43 to 24.86.
- x-intercept approaches negative infinity (-∞) to infinity (∞).
This ultimately implies that, a statement correctly compares functions f and g is that both functions have the same end behavior as x approaches -∞ but different end behavior as x approaches ∞.

Density is calculated by mass divided by volume.
This would be 60/24 (60 grams mass divided by 24 cm^3 volume)
60/24 = 2.5
This means the answer is B. 2.5 g/cm^3
