Answer:
The equivalent function: 
Step-by-step explanation:
The x-intercepts of the given function on the graph can be obtained by equating the function to zero.
This is because on the x-axis, the y-coordinate is zero.
The function that has the same x-intercepts on the graph from the given options is:
Alternate Method:
The answer can also be obtained by factorizing the question.
Answer:
25π cm^2 ≈ 78.5 cm^2
Step-by-step explanation:
The base is a circle with a radius of 5 cm. Its area is given by ...
A = πr^2
A = π(5 cm)^2 = 25π cm^2 ≈ 78.5 cm^2
x=0 and y=
Step-by-step explanation:
We need to solve the system by elimination and find values of x and y
Subtract eq(1) and eq(2)
Now Multiply equation (1) by 2 and subtract with eq(2)
So, x=0 and y=

Answer: 2
Step-by-step explanation:
I did it on a test!
The equation for the area of a circle is: A = πr^2.
A: Area
π: pi
r: radius
To find exact area (we leave pi in the answer):
- Find the radius of the circle.
The diameter 5ft.
The radius is half the diameter so r = 2.5 ft
-plug in 2.5 for r in the area equation
A = π(2.5)^2
2.5^2 is 6.25
A = π6.25
A = 6.25π
There you go! The exact area of the circle is 6.25π ft^2
To approximate the area instead of using π in the equation we use (3.14)
So,
A = (3.14)(2.5)^2
A = (3.14)*6.25
Approximated Area = 19.625 ft^2
