Answer:
it is 20.5
Step-by-step explanation:
you need to add all of the numbers together
Well, ok, the x intercepts aer where the function equals 0
also
if the x intercepts are r1 and r2 then the factored form of the function is
f(x)=a(x-r1)(x-r2) where a is a constant
well, we have it already in that form
f(x)=(x-3i)(x-3i)
the x intercept is at x=3i
standard form requires expansion
we expand to get
f(x)=x²-6i-9
Answer:
<h2>x = 10.3</h2>
Step-by-step explanation:
Use sine.
We have:
<em>look at the table in the picture</em>
Substitute:
<em>multiply both sides by 16</em>
Answer:
= 72a + 20s
Step-by-step explanation:
Given that;
a = number of adult tickets sold
s = number of student tickets sold.
According to given condition:
For first night;
=2(9a) + 5s
=18a + 5s
For second night:
= 3*18a + 3*5s
= 54a + 15s
Expression for total money of both nights:
= (18a + 5s ) + (54a + 15s )
Adding same terms:
= 72a + 20s
i hope it will help you!
