Answer: 4.83
Step-by-step explanation:
2.3*2.1= 4.83
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:
-10
Step-by-step explanation:
You always want to solve the inner function first.
g(-2)=(-2)³+3
=-8+3
=-5
g(-2)=-5 so you can replace g(-2) with -5
Now you just have f(-5)
Solve.
f(-5)=-5-5
f(-5)=-10
