Step-by-step explanation:

Answer:
Square root 112 Units.
Step-by-step explanation:
See the image attached for the work.
So you know 50% means half right? So then do 32*2 and you get 64.
Answer:
60 miles is equal to 4.8 inches.
Step-by-step explanation:
To find the answer to this question, we need divide 60 by 25 to find out how much to multiply 2 by so its equal.
60/25=2.4
2*2.4=4.8
60 miles is equal to 4.8 inches.
Hope this helps!
To get the vertex of the parabola we proceed as follows;
y=-7(x-4)^2-5
The above can be written as:
y=-7x^2+56x-117
The values of a,b and c are:
a=-7, b=56 and c=-117
x=-b/(2a)
x=-56/(-7*2)=4
but;
y=-7x^2+56x-117
y=-7(4)^2+56(4)-117
y=-5
Thus;
x=4 and y=-5
The vertex will be at point (4,-5)
