Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
- vertices of hyperbola:(±a,0) and (0,±b) if reversed
<h3>given:</h3>
- vertices: (0,±10)
- the hyperbola equation is inversed since the vertices is (0,±10)
- asymptotes:
<h3>let's solve:</h3>
- the asymptotes are in simplest and we know b is ±10
according to the question
therefore we got
note: the equation will be inversed
let's create the equation:
Answer:
c = 49/4
Step-by-step explanation:
The given expression is x^2 - 7x + c
This trinomial must be a perfect square.
Therefore, c must be a prefect square number.
So b^2 - 4ac = 0. That is discriminant must be equal to zero.
In the given expression a =1 and b = -7
Now plug in these values in the discriminant formula.
(-7)^2 - 4*1*c = 0
49 -4c = 0
4c = 49
c = 49/4
x^2 - 7x + 49/4 = (x - 7/2)^2
which is perfect square trinomial.
Thank you.
If a square contains 171 tiles you will need multiply 21 by 171 (171x21) which should give you the amount for the entire roof.
Hope this helps! :)
