Answer:
185 cents
Step-by-step explanation:
11 inches -------------> cost 55 cents
1 inch -----------------> cost 55/11 = 5 cents (unit rate)
37 inches -------------> costs 5 cents x 37 = 185 cents
Answer:
a) Vertex:
b) Vertex:
Step-by-step explanation:
First we need to realize that these equations are the equations of parabolas.
the equation of parabola are generally written as:
where the vertex is the point . <u>(note that the sign of 'h' is changed!)</u>
<u>(also note that the value of 'a' doesn't matter for finding vertex point)</u>
given this information we can now easily find out the vertex of both parabolas
a)
by comparing it with the general equation above, we can see that -5 is in the place of '-h' and +3.5 is in the place of '+k'
we can write
and solve for h.
similarly,
hence the vertex of this graph is
b)
by comparing it with the general equation above, we can see that +1 is in the place of '-h' and -8 is in the place of '+k'
we can write
and solve for h.
similarly,
hence the vertex of this graph is
The find the answer for this particular question you would you would
multiply 12 by 300 which is 3600, and you would then multiply that by 5
which is 18000
Needing to find the circumference of a circle you you find that you need to use the equation C=2 π R
C= 28.26
this is how much fence they would need around the garden approximately.
60/30 as a mixed # is 2/1 or 2
