When given points (1,1) and (2,2), what is the slope ?

scoray [572]

Answer:

$m=1$

Step-by-step explanation:

Slope can be calculated using following formula

$m=\frac{y_2-y_1}{x_2-x_1}$ ----------- (1)

<u>Here</u>

$(x_1, y_1)=(1, 1) \ \ and \ \ (x_2, y_2) = (2, 2)$

Substitute values in equation (1)

$m=\frac{2-1}{2-1}$

$m=1$

High concentrations of carbon monoxide CO can cause coma and possible death. The time required for a person to reach a COHb leve

ale4655 [162]

Answer:

A) 10.38hours

B) 617.95 is the concerntration of CO

Step-by-step explanation:

A) when x=600

T= 0.0002x^2 - 0.316x + 127.9

T= 0.0002(600)^2 -0.316(600) + 127.9

T= 10.38secs

B) to find the concerntration, use Almighty formular

X=-b+-sqrt(b^2-4ac)/2a

0.0002x^2-0.316x-127.9=9

0.0002x^2 - 0.316x + 118.9=0

X= 0.316 +- sqrt(0.316^2) -4(0.0002×118.9)/(2×0.0002)

X= 0.316+(0.68817/0.0004)=962.05 or

X=-0.316 -0.68817/0.0004 =617.95

Therefore X is within the domain of 617.95 is the concerntration
