Answer:
No, they are not congruent
Step-by-step explanation:
By CD and EF being congruent, we want to know if they are equal.
What we can simply do here is to find the distance between the points present.
That is, the distance between C and D, the distance between E and F
To get the distances between two points , we use the following equation
D = √(x2-x1)^2 + (y2-y1)^2
For CD, we have
D = √(6 -(-1)^2 + (-7 + 7)^2
D = √(7)^2 = 7 units
For EF, we have
D = √(5-5)^2 + (-5-3)^2
D = √(-8)^2
D = √(64) = 8 units
This clearly shows that they are both not congruent
Answer:
a=6
Step-by-step explanation:
distribute:
3a-15-6=-15
combine like terms:
3a-21=-15
add 21 to each side:
3a=6
divide by 3:
a=2

Answer:
a) 2211.6812281 rad/min
b) 352 rpm
Step-by-step explanation:
A bicycle with 24-inch diameter wheels is traveling at 16 mi/h. Find the angular speed of the wheels in radians per minute. ___ radians per minute
How many revolutions per minute do the wheels make? (Round your answer to three decimal places.) ___ revolutions per minute
truck with 24-in.-diameter wheels is traveling at 16 mi/h.
---------
1 mile per hour = 88 feet per minute
16 mi/hr = 1408ft/minute
----------
Each revolution = pi*d feet = 4pi feet
(b) How many revolutions per minute do the wheels make?
rev/min
-------------
Each revolution = pi*d feet = 4pi feet
rpm = 1408 ft/min / 4pi feet
=~ 352 rpm
---------------
(a) Find the angular speed of the wheels in rad/min.
rad/min
-------------
rad/min = rpm*2*pi
= 352 rpm × 2× π
= 2211.6812281 rad/min
