1. You con solve the quadratic equation x^2+20x+100=50<span> by following the proccedure below:
2. Pass the number 50 from the right member to the left member. Then you obtain:
x^2+20x+100-50=0
</span><span> x^2+20x+50=0
</span><span>
3. Then, you must apply the quadratic equation, which is:
x=(-b±√(b^2-4ac))/2a
</span><span>x^2+20x+50=0
</span><span>
a=1
b=20
c=50
4. Therefore, when you substitute the values into the quadratic equation and simplify ir, you obtain that the result is:
-10</span>±5√2 (It is the last option).
Answer:
Acute
Step-by-step explanation:
All you have to do is rotate the current dots, and bam.
The equation showing the relationship between w and t is 
From the table, we have the following points:
(0,0) and (1,4)
Start by calculating the slope (m)

So, we have:

Simplify the numerator and the denominator

Divide 4 by 1

The equation is then calculated as:

This gives

Simplify

Hence, the equation is
