Answer:
81.64
Step-by-step explanation:
do 13 times 2 times pi
so 26 times 3.144
correct me if this is wrong
Problem 1
We replace every copy of x with 4c and simplify like so:
f(x) = 8 - 5x
f(4c) = 8 - 5*4c
f(4c) = 8 - 20c is the answer
This is equivalent to -20c+8.
====================================================
Problem 2
Same idea as before, but this time we'll plug in x = 2-k
Each x gets replaced with (2-k)
f(x) = 8 - 5x
f(2-k) = 8 - 5(2-k)
f(2-k) = 8 - 10 + 5k
f(2-k) = -2 + 5k
This is the same as saying 5k - 2.
====================================================
Problem 3
The steps are similar to earlier.
f(x) = 8 - 5x
f(4p+3) = 8 - 5(4p+3)
f(4p+3) = 8 - 20p - 15
f(4p+3) = -7-20p
This is the same as writing -20p - 7.
Answer:
(4.0) and (6.0)
Step-by-step explanation:
when the function cross the x- axis
the y-coordinate equals to zero
x2 - 10x + 24=0
x=6,4
y=0
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
