Answer:
b
Step-by-step explanation:
b is the answer to your test
Yea. The text book is either wrong or it knows something that we don't. Like as to why they would need to have two more feet. You're right though
Step-by-step explanation:
the diameter of a circle is simply 2×radius.
2×15.4 = 30.8 m
the diameter is 30.8 m is true.
the circumference of a circle is
2×pi×radius
2×pi×15.4 = 30.8×pi m
the circumference is 30.8pi m is true.
therefore, the circumference can be found using
2(pi)(15.4)
is true.
now, doing the pi multiplication :
30.8 × pi = 96.76105373... m
the approximate circumference is 96.7 m is true.
6 diameters would be
30.8×6 = 184.8 m
that is much longer than the circumference.
so, more than 6 diameters could be wrapped around the circle is false, if we understand it that this is supposed to wrap the circle once without any overhanging remainder.
Answer:
Step-by-step explanation:
You need to use vertex form of a quadratic to solve this.
Consider the vertex to be 
Another way of representing a quadratic is in "vertex form":
Now all you have to do is solve for a. You know that the vertex is 
and you have know the point of 
. Now, all you have to do is plug in these values and solve for a.
Now you know the equation is 
, but you need it in quadratic form. All you have to do is solve is distribute the 6:
You get:
a = 6
b = 0
c = 2
Please mark this as brainliest if it satisfies your question
Answer:
f(1/a) = 1/a² + 2/a + 1
Step-by-step explanation:
Step 1: Define
f(x) = x² + 2x + 1
f(1/a) is x = 1/a
Step 2: Substitute and Evaluate
f(1/a) = (1/a)² + 2(1/a) + 1
f(1/a) = 1/a² + 2/a + 1
