write a quadratic function in the given form whose graph satisfies the given condition.
has a vertex of (5, -2) & passes through the point (3, 6) in vertex form
pls help...important...dont steal
Answer:
f(x) = 2(x-5)²-2
Step-by-step explanation:
The equation of a parabola in vertex form is y=a(x-h)²+k where (h,k) is the vertex and "a" represents how stretched or compressed the parabola is and what direction it travels.
Given a vertex of (5,-2) the equation so far is y=a(x-5)²-2
Since we want the parabola to pass through the point (3,6) we must find a value of "a" that satisfies this:
y=a(x-5)²-2
6=a(3-5)²-2
6=a(-2)²-2
6=4a-2
8=4a
2=a
This means that the quadratic function is f(x) = 2(x-5)²-2
The radius of the a circle is:
is a line segment with its endpoints on the circle.
is a line segment from the center of a circle to a point on the circle
is a chord that passes through the center of a circle. It is twice the length of a radius of that circle
is a part of a circle with all its points on the circle
Step-by-step explanation:
The radius of the a circle is:
Is a line segment from the center of a circle to a point on the circle.
So, (b) part is the correct answer.

V=πr2h/3
r=3V
πh=3·72
π·6≈3.38514cm
Matt is bringing 0.4 of a cake to school. What fraction of the cake is he bringing?
Answer:
2/5
Step-by-step explanation:
also=4/10
4/10
=2/5
Here, Matt is bringing 0.4 of cake.
For the denominator:
We are taking 1 for [.] decimal and take 0 for 4.
So, its fraction becomes 4/10=2/5 [if we divide both denominator and lobe by 2].

Answer:
B) -1/2
Step-by-step explanation:
(2, 3) and (4, 2)
Slope:
m=(y2-y1)/(x2-x1)
m=(2-3)/(4-2)
m= (-1)/2
m= -1/2
The Slope of the given line is -1/2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
We take two points from the graph as (2, 3) and (4, 2).
Now, the slope of line is
= (3-2)/ (4-2)
= -1 / 2
= -0.5
Using Slope intercept form
y= mx+ b
y= -0.5x+ b
and, b = 4
so, the Equation of line is y= -0.5x+ 4.

Step-by-step explanation:
intercepts are points where the graph cuts the axes
Answer:
(- 40, 0 ) and (0, 15 )
Step-by-step explanation:
The x- intercept is the point on the x- axis where the line crosses, then
x- intercept = (- 40, 0 )
The y- intercept is the pont on the y- axis where the line crosses, then
y- intercept = (0, 15 )
