Answer:
20%
Step-by-step explanation:
Well if there's 5 answers for the question, and he answered two questions. That means the two questions together have 10 answers.
He chose one answer for each question, that is 2/10 or 1/5 or 20%
Ok so domain is all allowed numbers
look at deonomenator and don't allow any numbers that will make it zero
none
that means
domain=all real numbers
vertex
in form
y=a(x-h)^2+k
(h,k)=vertex
we have
y=-2(x+3)^2-1
h=-3
k=-1
vertex=(-3,-1)
range
the vertex opens down so max is y=-1
y≤-1
domain is all real
vertex is (-3,-1)
y≤-1
C
Step-by-step explanation:
(x−1)²−9=0
(x-1)²= 9
x-1 = ±√9
x-1 = ±3
x = 1-3=-2 or x=1+3=4
the solution = {-2,4}
Answer:
(a) 74553
(b) 172120
(c) 234802
Step-by-step explanation:
Given
Solving (a): 1998
Year 1998 means that:
So, we have:
--- approximated
Solving (b): 2003
Year 2003 means that:
So, we have:
--- approximated
Solving (c): 2006
Year 2006 means that:
So, we have:
--- approximated
