Given:
The equation of a parabola is:
To find:
The vertex of the graph of the given equation by using a graphing calculator.
Solution:
We have,
By using the graphing calculator, draw the graph of the given equation as shown below.
From the below graph it is clear that the function is maximum at point (1.75,10.125).
So, the vertex of the given equation is (1.75,10.125).
Therefore, the correct option is c.
In order to calculate the
number of steps, we need to know how much 22cm goes into 3.3m.
Formula:
1 meter = 100 centimeters
3 meters = 300 centimeters
.3 meters = 30 centimeters
3.3 meters = 330 centimeters
=
And now we know, 165 divided by 11 is equal to
15.
So there you go. 15 steps.
Answer:
11.0 cm
P=38 cm
38/3=12.67cm length of one side
Base of triangle = 12.67/2 =6.34 cm
Use formula 
x = altitude of triangle
"Enlargement" here implies that the two pentagons are similar. Because of similarity, the following equation of ratios must be true: 7/15 = x/7. Then 15x=49, and x = 49/15 = 3.27 cm, approximately.
Rounded to the nearest tenth, that comes to 3.3 cm.
