Answer:
Vertex: (-4, 1)
X intercepts: (-6, 0) and (-2, 0)
Y Intercepts: (0, -5)
Axis of Symmetry: X= -4
Step-by-step explanation:
Vertex of the parabola is the maximum or minimum point on the graph of the quadratic function
X intercepts are points of when a line or in this case a parabola intercepts the x axis, and where y = 0
Y intercepts are point of when a line or in this case a parabola intercepts the y axis, and where y = 0
Axis of symmetry is the point where if you divide the parabola in half, shows a symmetrical side
La respuesta correcta es la C
Answer:
The probability that a letter at random is from V is 5/26 or 19.23%
The student is not correct.
Absolute value means distance from zero
|-9| = 9
|4| = 4
Since 9 is greater than 4,
|-9| is greater than |4|
In other words, -9 is further from zero then 4
Using an exponential function, it is found that if the original statement is true, children were killed by guns in 1995.
<h3>Exponential function:
</h3>
An increasing exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the increase rate, as a decimal.
In this problem:
- Researching on the internet, the original problem states that the number of children killed by guns has doubled each year since 1950, hence there is an increase of 100% every year, that is, .
- 100 children were killed by guns in 1950, hence .
Then:
1995 is 45 years after 1950, hence:
If the original statement is true, children were killed by guns in 1995.
