Answer:
C. this is not a functional relationship.
Step-by-step explanation:
In other words, for each x-value, there is only one corresponding y-value.
For the equation x2 + y2 = 10, find the y-value for a given x-value.
Let x = 1.
Since (-3) · (-3) = 9 and 3 · 3 = 9, there are two y-values for x = 1.
There are 9! ways in total, however, notice that certain letters repeat themselves.
For example, a permutation could be assistant but the third s could replace the first it would still be assistant.
So,
9!/(3!)(2!)(2!) <-- 3 s's, 2 a's and 2 t's
Therefore, the total permutations are: 15120
Hope I helped :)
Answer:
Step-by-step explanation:
= x²(-3 +5) +y²(2 -3) +5xy -2y
= 2x² -y² +5xy -2y
a) there are 4 terms in the simplified expression
b) 2 terms have negative coefficients (-y² and -2y)
radius of small circle = 16 m
radius of large circle is doubled so it will be 32 m
Area of the larger circle = π x 32^2 = 1,204π m^2
answer
1,204π m^2
Answer:
0
Step-by-step explanation:
Simplifying
x2 + -4x + -12 = 0
Reorder the terms:
-12 + -4x + x2 = 0
Solving
-12 + -4x + x2 = 0
Solving for variable 'x'.
Factor a trinomial.
(-2 + -1x)(6 + -1x) = 0
