Answer:
a(75) = 793
Step-by-step explanation:
Arithmetic Explicit Formula: an = a1 + (n-1)d
Step 1: Find equation
d = (1-(-10)) = 11
a1 = -21
an = -21 + 11(n-1)
Step 2: Plug in 75 as <em>n</em>
a(75) = -21 + 11(75-1)
a(75) = 793
And we have our final answer!
In the question it gives you what "s" is which is 3, so plug that in instead of s.
c = 25s²
c = 25(3²)
c = 25(9)
c = 225 << your answer
hope this helps, God bless!
Answer:
x different from 2
Step-by-step explanation:
The function is written as the quotient:
that can give us a real value for any value of x except for x=2 that creates a ZERO in the denominator, making the division undefined.
So the only value for which the function cannot be evaluated is x=2, therefore the function's domain is all the real numbers except for x=2.
