The quadratic equation in its generic form is:
ax2 + bx + c
To complete squares we must add the following term:
(b / 2) ^ 2
The equation is:
ax2 + bx + c + (b / 2) ^ 2
We have the following equation:
x ^ 2 - 5x + k = 7
By completing squares we have:
x ^ 2 - 5x + (-5/2) ^ 2 = 7 + (-5/2) ^ 2
Rewriting:
x ^ 2 - 5x + 6.25 = 7 + 6.25
Answer:
A constant term should be used to complete the square is:
6.25
Answer:
u = (b/hn)
Step-by-step explanation:
The inverse!!
Answer:
Step-by-step explanation:
If APB is measured in radians, then the arc length AB = APB(r) where r is the radius of the circle.
1,000,000 is 1 million
look at the previous digit
if it is less than 5 then leave the millions place as is and replace the following digits with zeroes
if it is equal to or greater than 5, add 1 to the millions place and replace the following digits with zeroes
296,386,482
3<5
round down (leave as is baseically)
296,000,000 is rounded
The parabola hits (-2,1) and (0,-1).
As you can see from the pictures, we can immediately cross out options B and D, since both parabola open upwards.
From the pictures, we can see that the answer is C, since only that parabola opens downwards and hits the points (-2,1) and (0,-1).
