Answer: f(x) is just a fancy way of writing y in an equation
Step-by-step explanation:
Example: f(x)= 2x+4 is the same as y= 2x+4
To convert radians to degrees, multiply by 180/p, like this:
<span>degrees = radians x (180 / π ) </span>
<span>To convert degrees to radians, multiply by p/180, like this : </span>
<span>radians = degrees x ( π/180) </span>
<span>(A) This will use the formula for radians to degrees. </span>
<span>π/3 x (180/π) </span>
<span>The pi's cancel, leaving you with: 180/3 = 60 degrees
False
(B) </span><span>An angle that measures π/6 radians also measures 30°
</span>π/6 x (180/π) = 30 degrees.
<span>True
</span>(C) <span>An angle that measures π/3 radians also measures 60°
</span><span>π/3 x (180/π) = 60 degrees.
</span>True
(D) An angle that measures 180 degrees also measures <span>π/2</span>
π/2 x (180/π) = 90 degrees.
False

I'm not sure if these are all right...
The <u>/</u> means that it is a fraction
Some fractions your may need to simplify
Answer:
a=21
AB=23.9
BC=19.5
CD=(23.9)
AD=19.5
Step-by-step explanation:
Each pair of parallel sides are equal in a parallelogram. Sense both pairs use the same variable we can just choose the easiest to solve which would be:
a-1.5=19.5
add 1.5 to both sides
a=21
now substitute 21 in for a in each equation.
AB=CD so
AB=23.9
BC=AD so
BC=19.5
CD=(21)+2.9 so
CD=(23.9)
AD is given so
AD=19.5
When the ball reaches the ground, its height is 0.
We set the height function equal to zero and solve for t, the time.
h = -16t^2 + 250
-16t^2 + 250 = 0
16t^2 - 250 = 0
or
or
or
We discard the negative solution since time must be positive.
The positive solution is
Answer: 4.0 seconds
