twenty-six=26
2 tens 6 ones= 26
25=25
20+6=26
25 is the odd one out.
Circumference of a circle - derivation
This page describes how to derive the formula for the circumference of a circle.
Recall that the definition of pi (π) is the circumference c of any circle divided by its diameter d. Put as an equation, pi is defined as
π
=
c
d
Rearranging this to solve for c we get
c
=
π
d
The diameter of a circle is twice its radius, so substituting 2r for d
c
=
2
π
r
If you know the area
Recall that the area of a circle is given by
area
=
π
r
2
Solving this for r
r

=
a
π
So
r
=
√
a
π
The circumference c of a circle is
c
=

Answer:
tire A=39 revolutions
tire B=38 revolutions
tire C= 37 revolutions
Step-by-step explanation:
The question is on circumference
Tire A diameter = 15 +4.60+4.60=24.20 inches
Tire B diameter= 16+4.43+4.43=24.86 inches
Tire C diameter=17+4.33+4.33=25.66 inches
Finding the circumference/single revolution
Tire A = 2×3.14×24.20=151.98 inches
Tire B= 2×3.14×24.86=156.12 inches
Tire C=2×3.14×25.66=161.15 inches
Number of revolutions made
Track length=500 feet.............change feet to inches
500×12=6000inches
Revolutions for tire A= 6000/151.98 =39.47⇒39 revolutions
Revolutions for tire B=6000/156.12 =38.43⇒38 revolutions
Revolutions for tire C= 6000/161.15 =37.23⇒37 revolutions
There seems to be a flaw with this question because it says that there are five x-intercepts but the given information only gives you 4 x-intercepts to work with.
Even means the graph is symmetric about the y-axis
The best answer is <span>A.(–6, 0), (–2, 0), and (0, 0)
because you do not have to worry about another point (0,0). Plus we need (-6,0) for it to be symmetric with (6,0).
Consider function f(x) = x²(x-6)(x+6)(x+2)</span>²(x-2)<span>². It is even and fits these conditions as it has x-intercepts at (6,0), (-6,0), (-2,0), (2,0), and (0,0). again, the question does not tell us the fifth x-intercept, so we need to assume that there is another one that needs to be there...and so (-2,0) must have (2,0) for it to be even as well.</span>
