Answer:
The factors of given expression are 10+10√2 and 10-10√2.
Step-by-step explanation:
We have given a quadratic expression.
s²-20s-100
We have to find factors of given expression.
We use quadratic formula to find factors.
x = (-b±√b²-4ac) / 2a
From given expression, a = 1 , b = -20 and c = -100
Putting values in above formula, we have
x = (-(-20)±√(-20)²-4(1)(-100) ) / 2(1)
x = (20±√400+400 ) / 2
x = (20±√800) / 2
x = (20± √400×2) / 2
x = (20±20√2) / 2
x = 10±10√2
Hence, the factors of given expression are 10+10√2 and 10-10√2.
The answer is 19. You have to do 1/4 x 76/1 which is basically 76 divided by 4, which gives you 19.
Answer:
The slope of line k is - 4 .
Step-by-step explanation:
The slope of given line p is 1/4
Let the slope of line k which is perpendicular to is m.
When the two line are perpendicular to each other, the product of the slopes is always negative 1.
So, the slope of line k is given by
$2.27
4.99x0.55=2.74 off
4.99-2.74=2.25 before tax
2.25x0.01=0.02 tax
2.25+0.02=2.27 total
