<u>Part A</u>
<u />
So, the x-intercepts are 
<u>Part B</u>
The vertex will be a minimum because the coefficient of 
is positive.
The x-coordinate of the vertex is 
Substituting this back into the function, we get 
So, the coordinates of the vertex are 
<u>Part C</u>
Plot the vertex and the x-intercepts and draw a parabola that passes through these three points.
The graph is shown in the attached image.
Answer:
The circumference is pi times larger than the diameter of a circle.
Step-by-step explanation:
The formula of the circumference of a circle is
C = 2(pi)r = (pi)d
C = (pi)d
To find the ratio of the circumference to the diameter, divide both sides of the equation by d.
C/d = pi
The circumference is pi times larger than the diameter of a circle.
Hi there, the formula of a circle is C=πr. So, r=C/2π=28/2*π=4.45634, Therefore, the answer is 4.45634
Answer:
he saved $25
Step-by-step explanation:
The answer is 25 because 15 multiplied by 5 is 75 and 5 multiplied by 5 is 25.
Answer:
2.5 inches
Step-by-step explanation:
To find the radius when you only have the diameter then you divide the diameter in half and you get your radius
5/2= 2.5
