Answer:
Vertex ( 0,1) and it is maximum.
Step-by-step explanation:
Given : graph of parabola .
To find : What are the coordinates of the vertex of the graph? Is it a maximum or minimum.
Solution : We have given the graph of parabola
Vertex : the highest point ; the top.
Vertex : ( 0 , 1) because it cut at y ,
When the parabola opens down, the vertex is the highest point on the graph is called the maximum, or max.
Therefore, Vertex ( 0,1) and it is maximum.
Answer:
Step-by-step explanation:
The quadratic equation in its standard form is:
Now, we are given 5 points of the parabola (if you graph a quadratic equation you will have a parabola), however we only need to choose three points to find the coeficients , and in the quadratic equation.
So, let's choose the first three points:
(-1,14):
(1)
(0,7):
(2)
(1,4):
(3)
Substituting (2) in (1) and (3):
(4)
(5)
At this point we have a system with two equations.
Adding (4) to (5):
(6)
Isolating :
(7)
Substituitng (7) in (3):
(8)
Isolating :
(9)
Now we have the three coeficients and we can write the quadratic equation:
13-(-3)
adding the opposites, you get 16 degrees.
-3+13
using a number line: 3 to the left, 13 to the right=10 degrees
For example: 10-(-1)= positive 11. no. you could have -1-(-9). Add the opposites and you get positive 8.
What is %15 of $27.00
Answer:
5.27 , 4.05
Step-by-step explanation:
35.15 times .15= 5.27
27.00 times .15= 4.05
To find the answer to a percent, take the percentage and place a decimal in front of the number than multiply it my the total amount. like so.
The number representing Liam's share is 2; for Sarah's share, it is 3. The difference of those is 1, so each 1 unit of share must be £30, the difference between the amount Sarah got and the amount Liam got.
Emily got 5 shares or £30 × 5 = £150.
