4 The size 4 soccer ball Sean's team uses should weigh
1 answer:
Most 2 balls could weigh = 0.74 kilograms, Least 2 balls could weigh = 0.62 kilograms
Step-by-step explanation:
<em>Maximum weight of soccer ball = 0.37 kilogram</em>
<em>Minimum weight of soccer ball = 0.31 kilogram</em>
<u>One bag has two balls</u>
<em>1. To find out the most weight, we need to assume that both balls are of the maximum weight so,</em>
Weight of ball 1 + Weight of ball 2
0.37 + 0.37
= 0.74 kilograms
<em>2. To find out the least weight, we need to assume that both balls are of the minimum weight so,</em>
Weight of ball 1 + Weight of ball 2
0.31 + 0.31
= 0.62 kilograms
The weight of two balls are
<em>Therefore, the most these two balls could weigh together is 0.74 kilograms and the least these two balls could weigh together is 0.62 kilograms.</em>

ANSWER
EXPLANATION
Since the directrix is
the axis of symmetry of the parabola is parallel to the y-axis.
Again, the focus being,
also means that the parabola will open upwards.
The equation of parabola with such properties is given by,
where
is the vertex of the parabola.
The directrix and the axis of symmetry of the parabola will intersect at
The vertex is the midpoint of the focus and the point of intersection of the axis of the parabola and the directrix.
This implies that,
and
The equation of the parabola now becomes,
Thus, the distance between the vertex and the directrix.
This means that,
Since the parabola opens up, we choose
Our equation now becomes,
This simplifies to
or
This is the same as,
The correct answer is D .
