Answer:
The car must have a speed of 25 kilometres per hour to stop after moving 7 metres.
Step-by-step explanation:
Let be
, where
is the stopping distance measured in metres and
is the speed measured in kilometres per hour. The second-order polynomial is drawn with the help of a graphing tool and whose outcome is presented below as attachment.
The procedure to find the speed related to the given stopping distance is described below:
1) Construct the graph of
.
2) Add the function
.
3) The point of intersection between both curves contains the speed related to given stopping distance.
In consequence, the car must have a speed of 25 kilometres per hour to stop after moving 7 metres.
Answer:
I believe that the answer is A or the first choice.
Step-by-step explanation:
because the rule for x is +1 and its y is the only one with a rule.
The rule is +1/2
Answer:
Las cosas que se pueden contar (i.e. Contar y clasificar frutas) así como cosas que se pueden dividir se pueden medir en fracciones (i.e. Cortar un pastel), mientras que las cosas que no se pueden contar, de naturaleza no discreta, así como cosas que no se pueden dividir (i.e. Líquidos, material granulado) se pueden medir en decimales.

The circle is open i think is the right answer i hope i got it right if not im very sorry :(
Answer:
Option D, x = 4
Step-by-step explanation:
Option A: y = 4 doesn't work because that line would be horizontal
Option B: y = 4x doesn't work because that would be diagnol
Option C: x = -4 doesn't work because that would a vertical line at -4
<em>Option D: x = 4 works because that would a vertical line at 4</em>
<em />
Answer: Option D, x = 4
