Answer:
I will stick to CCW 216 degrees
Step-by-step explanation:
That pentagon has 5 shape and has the same distance with each angle, so rotate one point to another closest point need 72 degrees (360/5 = 72). When
A rotate to C, it need to rotate 144 degrees for CW and 216 degrees for CCW.
Answer:
x=4/5y-4
Step-by-step explanation:
The answer must take into account that the order is irrelevant, that is that it is the same J, Q, K that Q, K, J, and K, J, Q and all the variations of those the three cards.
The number of ways you can draw 50 cards from 52 is 52*51*50*49*48*47*...4*3 (it ends in 3).
,
But the number of ways that those 50 cards form the same set repeats is 50! = 50*49*49*47*....3*2*1
So, the answer is (52*51*50*49*48*....*3) / (50*49*48*...*3*2*1) = (52*51) / 2 = 1,326.
Note that you obtain that same result when you use the formula for combinations of 50 cards taken from a set of 52 cards:
C(52,50) = 52! / [(50)! (52-50)!] = (52*51*50!) / [50! * 2!] = (52*51) / (2) = 1,326.
Answer: 1,326
The roots are simple
ok, so
remember some nice rules
if the zeores of the function (where the graph hits the x axis) are r1,r2...rn the the factors are (x-r1)(x-r2)...(x-rn)
if the degree (how many factors, or x^degree) is odd, then the ends of the graph go in oposite directions, from bottom left to top rght
if the leading coefient (first term) has a negative like f(x)=-3(x-r1)(x-r2)...
then the graph is reflected across the x axis
if the degree is even, the ends go in same direction
if leading coefient is negative, then ends both go down
the roots are wehre the graph hits te x axis
if yo hav a root repeat, that's called a multiplicaty
(x-r1)^2 is even multiplicy
(x-r1)^3 is odd
odd multilicity means the line goes though the graph
even means that the graph just touches the graph at that point and bounces off
this is confusing so sorry
Answer:
x = 0.5
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form: x = -1/2
