Answer:

A. 0.25 inches

B. 0.125 inches

Step-by-step explanation:

A.

The smallest increment is represented by 1/4. Converting this into decimal form would make this 0.25.

Work:

1/4 = x/100

1 × 100 = 4 × x

100 = 4x

25 = x

25/100

0.25

B.

The uncertainty is what is not labeled on the ruler. We know 0.25 (1/4), 0.50 (2/4), and 0.75 (3/4) are labeled on the ruler. Out of all the options, 0.125 is not labeled. Therefore, 0.125 is the uncertainty.

What is the slope of the line that passes through the points (-4, -9) and (5, 3)
egoroff_w [7]

Answer:

4/3

Step-by-step explanation:

Moving from (-4, -9) to (5, 3), x (the 'run') increases by 9 from -4 to 5, and y (the 'rise') increases by 12 from -9 to +3.  Thus, the slope of the line connecting the two points is

m = rise / run = 12/9 = 4/3

It may help to think of the change in x (9) as the horizontal leg of a right triangle and the change in y (12) as the vertical leg.  Then  

m = (vertical leg length) / (horizontal leg length) = 12/9 = 4/3

P-4=-9+p i don't know how to determine whether its an infinite solution, or n solution.
lara [203]
Subtract P from both sides and be left with -4 = -9, which means no solutions.

The radius of a circular disk is given as 21 cm with a maximum error in measurement of 0.2 cm. (a) Use differentials to estimate
sergiy2304 [10]

Answer with Step-by-step explanation:

We are given that

Radius of circular disk=r=21 cm

dr=0.2 cm

a.Area of circular disk=A=\pi r^2

d A=2\pi rdr

d A=2\pi (21)(0.2)=8.4 \pi cm^2

d A=8.4\times 3.14

Where \pi=3.14

d A=26.38 cm^2

b.Relative error=\frac{dA}{A}=\frac{26.38}{\pi (21)^2}

Relative error=0.0191

Percentage(%) error=0.0191\times 100=1.91%
