A. would be the answer because if you distribute/factor the expression you would get A.
Answer:
3.5 m/s²
Step-by-step explanation:
We are given;
- The force of a bicycle as 3.5 × 10² N
- Mass of the bicycle as 1.0 × 10² kg
We are required to determine the acceleration of the bicycle;
From Newton's second law of motion;
F = ma
Rearranging this;
a = F÷ m
Therefore;
Acceleration = 3.5 × 10² N ÷ 1.0 × 10² kg
= 3.5 m/s²
Thus, the acceleration of the bicycle is 3.5 m/s²
Width of rectangle = x
Length =3x+7
Perimeter of rectangle = 158cm
2(l+w)=158
2(3x+7+x)=158
2(4x+7)=158
8x+14=158
8x=158-14
x=144/8
x=18
Therefore the width of the rectangle is 18cm
Length=3x+18+7
54+7=61cm
Area=lxw
=61x18
=1098^2
For this case we have a quadratic equation of the form:

What we must keep in mind to know which direction opens the parabola, is the value of a.
We have two options:
If a <0 the parabola opens down
If a> 0 the parabola opens up
We have the following equation:

We observed that:

Therefore, the parable opens up.
Answer:
the direction that this parabola opens is:
Upwards
Answer:
yes, it is
