The standard form of the quadratic function whose graph is a parabola with the given vertex and that passes through the given point is;
y = x² + 6x + 13
We are given;
Vertex coordinate; (-3, 4)
A point on the graph; (0, 13)
The vertex form of a quadratic equation is given by;
y = a(x - h)² + k
Where h, k are the coordinates of the vertex.
a is the letter in general form of quadratic equation which is;
y = ax² + bx + c
Thus, at point (0, 13) at the vertex of (-3, 4), we have;
13 = a(0 - (-3))² + 4
⇒ 13 - 4 = 9a
9a = 9
a = 9/9
a = 1
Since y = a(x - h)² + k is the vertex form, let us put the vertex values for h and k as well as the value of a to get the quadratic equation;
y = 1(x - (-3))² + 4
y = x² + 6x + 9 + 4
y = x² + 6x + 13

Answer:
The formula for this quadratic function is x*2 +6x+13
Step-by-step explanation:
If we have the vertex and one point of a parabola it is possible to find the quadratic function by the use of this
y= a (x-h)*2 + K
Quadratic function looks like this
y= ax*2 + bx + c
So let's find the a
y= a (x-h)*2 + K where
y is 13, x is 0, h is -3 and K is 4
13= a (0-(-3))*2 +4
13=9a +4
9=9a
9/9=a
1=a
The quadratic function will be
y= 1(x+3)*2 + 4
Let's get the classic form
(x+3)*2 = (x+3)(x+3)
(x*2+3x+3x+9)
x*2 +6x+13
f(0) = 13

Answer:
part A - 256 stickers
part B - 8 stickers each
Step-by-step explanation:
hope this helps
Answer:
a) 256
b) 8
Step-by-step explanation:
a) as it says in the question, each box contains 64 stickers. Mrs Kim bought 4 boxes , so she has 4 times more than a single box (64 stickers)
The calculation is simple: 64 x 4, which equals 256
b) If there are 256 stickers all-together and she has 32 people to share them equally with, you have to divide 256 by 32 to see how many stickers each person will get:
256 ÷ 32 = 8
Answer:
Average of Gilbert in last 5 test = 86.6
Step-by-step explanation:
Given:
Score earned by Gilbert in last 5 test = 94, 72, 83, 94, 90
Find:
Average of Gilbert in last 5 test
Computation:
Average value = Sum of all events / Total number of events
Average of Gilbert in last 5 test = Sum of all last results / Number of results
Average of Gilbert in last 5 test = [94 + 72 + 83 + 94 + 90] / 5
Average of Gilbert in last 5 test = [433] / 5
Average of Gilbert in last 5 test = 86.6

Step-by-step explanation:
Answer:
0.5 seconds (at 100 feet in the air).
Step-by-step explanation:
So, the height of the ball can be modeled by the function:
Where h(t) represents the height in feet after t seconds.
And we want to find its maximum height.
Notice that our function is a quadratic.
Therefore, the maximum height will occur at the vertex of our function.
The vertex of a quadratic function in standard form is given by the formula:
In our function, a=-16; b=16; and c=96.
Find the x-coordinate of the vertex:
So, the ball reaches its maximum height after 0.5 seconds of its projection.
Notes:
To find it’s maximum height, we can substitute 1/2 for our function and evaluate. So:
Evaluate:
So, the ball reaches its maximum height of 100 feet 0.5 seconds after its projection.
