Circumference of a circle is found with the equation
C = 2 × pi × r
where r is the radius. So for your problem...
C = 2 × 3.14 × 4
C = 25.12 meters
The correct graph is graph 4.
You can find this by looking for recognizable points. This is the easiest way to find composite graphs. In the graph f(x) =|x − 5| + |x − 4| both 5 and 4 yield the answer of 1. You can see that in the examples below:
<span>f(x) =|x − 5| + |x − 4|
</span><span>f(5) =|5 − 5| + |5 − 4|
</span><span>f(5) =|0| + |1|
f(5) = 0 + 1
f(5) = 1
</span><span>f(x) =|x − 5| + |x − 4|
</span><span>f(4) =|4 − 5| + |4 − 4|
</span><span>f(4) =|-1| + |0|
f(4) = 1 + 0
f(4) = 1
Now we can look for graphs that have those two reference points. The 4th graph is the only one that has those. </span>
30% of 90 <em>whenever it says "of" put in a multiplication sign </em>
30% x 90 <em> take out the % sign (percent means divided by 100)</em>
30/100 =3/10 <em>simplify,then multiply by 90</em>
3/10 x 90 = 270/10 <em> simplify</em>
270 = 27
90 - 27 = 63 <em>subtract 27 because it is the amount read so far from the total</em>
Keisha has to read 63 more minutes to reach her goal.
Answer:
39 = r-13
Step-by-step explanation:
The sum of gains is
... (14 yd) + (-32 yd) + (3 yd) + (-19 yd)
... = (14 +3 -19 -32) yd . . . . . . it is often convenient to rearrange the numbers to facilitate mental arithmetic
... = (-2 -32) yd
... = -34 yd
The net change of position was -34 yards.
