Answer:
1 : 30
Step-by-step explanation:
4 seconds : 2 min
however we know that 1 min has 60 seconds. Hence 2 min will have 2 x 60 = 120 seconds
Therefore we can substitute 2 min with 120 seconds
4 seconds : 2 min
4 seconds : 120 seconds (simplify by dividing both sides by 4)
4/4 : 120/4
1 : 30
Answer:
The leading coefficient is positive, which means that the function has a minimum value.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
It's vertex is the point
In which
If a<0, the vertex is a maximum point, otherwise, it is a minimum point.
In this question:
So , which means that the function has a minimum value.
Yes it can be considered as a rectangle

Step-by-step explanation:
Answer:
The solutions will contain an infinite amount of negative numbers.
Step-by-step explanation:
Given x < 0
What does this mean?
First, carefully examine the sign in the inequality. It says less (which is different from less and equal)
Then explain it's meaning.
x < 0 just means that the solutions will contain an infinite amount of negative numbers but NOT zero. This defines the correct answer.
