Answer:
A is the correct answer
Step-by-step explanation:
The radius is half of the diameter. So it has to start from point 'A'. The only choice using point A is TA, so choice A is the correct choice
Other radii could be AG, AP, or AR, but none of those choices are listed.
Answer:
5n
Step-by-step explanation:
cost of one helmet = $5
let 'n' be the number of person that is n=1,2,3,4........
note that the value of n is always a natural number
therefore the expression = 5n
where 5 is the cost one helmet
n is the number of persons
Answer:
The vertex is (-3, 7)
Step-by-step explanation:
As the equation is already in 'rectangular form), to work out the vertex, we can just compare this equation to that of the standard parabola y = x^2, and in particular, consider how it has been translated:
the (x+3) part moves the graph the the left 3 (i.e in the negative direction), while the +7 moves the graph up 7.
So as the vertex of the simple parabola y = x^2 is (0,0), the vertex of this graph is just (-3,7).
Note that the -2 at the front doesn't impact this vertex - this -2 just changes the 'scale' of the parabola (i.e makes it more narrow, and also turns it upside down as it's a negative number).
Answer:
18%
Step-by-step explanation:
total = 72 + 328 = 400
percent non-fiction = 72/400 × 100% = 18%
No. Only a line reflection will change orientation
