Answer:
y = 2.5(x + 2)^2 - 3
The answer is A
Step-by-step explanation:
The general equation for the vertex is
y = a (x + b)^2 + c
a we are not certain about
b = 2
c = - 3
y = a(x + 2)^2 - 3 Now we have to solve for a.
a is found by using the one point we know (0,7) It means when x = 0 y = 7 so just put those two numbers in.
7 = a(0 - 2)^2 - 3
7 = a (- 2)^2 - 3 Add 3 to both sides.
7 + 3 = a(4) Combine 7 and 3
10 = 4a Divide by 4
10/4 = a Do the actual division
2.5 = a
Answer: See above
Answer:
240
Step-by-step explanation:
The circuit's power is modeled by a quadratic function, whose graph is a parabola.
The maximum power is reached at the vertex.
So in order to find the maximum power, we need to find the vertex's y-coordinate.
We will start by finding the vertex's x-coordinate, and then plug that into P(c).
The vertex's x-coordinate is the average of the two zeros, so let's find those first.
-15c(c-8)=0, so either -15c or c-8 equals 0, so c=0 or c=8.
Now let's take the zeros' average:
(0+8)/2=4.
The vertex's x-coordinate of this parabola is 4. Now let's find P(4).
P(4)=-15(4)(4-8)
240.
The maximum power of this circuit is 240 watts.

Answer:
calculus, geometry, arithmetic among a few
Step-by-step explanation:
Mathematics is involved in winter Olympics in different aspects like arithmetic which helps in scores, measurements, quantities and motion of the sport like hockey, running.
Scoring in ice skating involves arithmetic operation when an individual element is assigned points and judged on performance level( triple axle is 3 points but overall performance and artistry is measured by the judges).
Another is Calculus which helps to understand the change in acceleration and velocities while each skaters start at zero then win, Lines in Geometry such as the finish/start/sight lines helps players with angles of reflection, measuring angles and angles of incidence.
