Answer:
<u><em>7 hours 30 minutes and 0 Seconds</em></u>
Step-by-step explanation:
- <em>60 minutes in 1 hour</em>
- <em>7:30 - 3:00</em>
- <em>60 * 10 = 600 Seconds</em>
- <em>Plus the 30 minutes which converts to 20 seconds</em>
- <em>Change that into hours and minutes</em>
Answer:
y = 3 - x + x²
Step-by-step explanation:
Given the data:
x. y
-5 33
-2 9
-1 5
0 3
3 9
4 15
6 33
General formof a quadratic model:
y = A + Bx + Cx²
Using the quadratic regression model solver for the data Given:
The quadratic model fit obtained is :
y = 3 - x + x²
A number is multiplied by 8 and the result is 28.
A number= x.
8(x)= 28
Divide both sides by 8.
28/8= 3.5
x= 3.5
I hope this helps!

Answer:

Step-by-step explanation:
Consider the given equation

Factor form of a parabola: It displays the x-intercepts.
.... (1)
where, a is a constant and, p and q are x-intercepts.
So, we need to find the factored form of the given equation.
Splinting the middle term we get


.... (2)
On comparing (1) and (2) we get

It means x-intercepts of the given parabola are 4 and 2.
Therefore, equivalent forms of the equation is y=(x-4)(x-2).
