</u>
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
3x + 2 = 17
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Subtraction Property of Equality] Subtract 2 on both sides: 3x = 15
- [Division Property of Equality] Divide 3 on both sides: x = 5
the balloon starts at 158 thats our set number
then it goes up 56 feet a minute, you add that to your height
after that you have the variables h and t you would write it as
h= 56t+ 158
x=3 and y = -1. ....thank uh.. ,
Answer is 31.83
Explanation: The circumference is 2pir where r is the radius
2pi= 200
r= 200/2pi = 100/pi= 31.83
Hope this helps!
Radians are another way to measure angles.
<span>There are 2*pi radians in a full turn so 360 degrees = 2*pi radians </span>
<span>180 degress = pi radians </span>
<span>90 degrees = pi/2 radians etc </span>
<span>Quite often we talk about measures of radians in terms of multiples (or fractions) of pi. </span>
<span>To convert from degrees to radians you divide by 180 and multiply by pi. </span>
<span>To convert from radians to degrees you do the reverse and divide by pi and multiply by 360. </span>
<span>The term "two radians" therefore is the size of an angle. We can think of it in degrees if that makes more sense by converting it as described above. </span>
<span>2/pi*180 = about 114.6 degrees. </span>
<span>If you are doing any calculus you should always make sure you use radians for your angles.</span>
