I didnt fully understand what the questions was asking. all I got from it was slope-intercept and even then it didn't make sense so I created the equation that goes throw those 2 points and added the y intercept to it.

hope this somehow helped...

Which of the following is the graph of y= - x + 1

Ksivusya [100]

Answer:

See picture below

Step-by-step explanation:

To graph properly, remember that:

The y intercept of the function, is the value of the function when x=0, and tells (in this case y=1 is the intercept). Locate this point in the graph.
The x intercept, which is the value of x when y=0 is x=1. Locate it in the graph.
You now have two points of a straight line: join this two points and you would have done it!

The length and width of a rectangle are measured as 30cm and 24cm, respectively, with an error in measured of

larisa [96]

Answer:

The maximum error in the calculated area of rectangle is 5.4 cm².

Step-by-step explanation:

Given : The length and width of a rectangle are measured as 30 cm and 24 cm, respectively, with an error in measured of at most 0.1 cm in each.

To find : Use differentials to estimate the maximum error in the calculated area of rectangle ?

Solution :

The area of the rectangle is $A=l\times w$

The derivative of the area is equal to the partial derivative of area w.r.t. length times the change in length plus the partial derivative of area w.r.t. width times the change in width.

i.e. $dA=\frac{\partial A}{\partial L}\Delta L+\frac{\partial A}{\partial W}\Delta W$
