The handbook of chemistry and physics lists the density of a certain liquid to be 0.7988 g/mL. Taylor experimentally finds this

liquid to have a density of 0.7925 g/mL. The teacher allows up to +/- 0.500% error to make an “A” on the lab. Did Taylor make an “A”?

Answer:

Yes

Step-by-step explanation:

0.7988-0.5= 0.7488

0.7988+0.5= 1.2988

0.7925 lies between these values.

however, are you certain that the question has 0.500 as the uncertainty not 0.050

What is the x intercept for y=(2x(x-3))/(x-1). ?
Ainat [17]

Answer:

( 0,0) and (3,0)

Step-by-step explanation:

y=(2x(x-3))/(x-1)

Set y = 0

0 =(2x(x-3))/(x-1)

Multiply each side by x-1, which makes x not equal to 1

0 =(2x(x-3))

Using the zero product property

2x=0  x-3 =0

x=0   x= 3

The x intercepts are x=0   x= 3

( 0,0) and (3,0)

75 Points If You get This Right
NNADVOKAT [17]

Answer:

1.   2

2.  6

3.  2

4.  3

5.  1

6.   1

Step-by-step explanation:

First put the data in order from smallest to largest

2,2,2,3,3,6

The minimum is 2

The maximum is 6

The median is 2,2,2    ,3,3,6  is between the 2 and 3  (2+3)/2 = 2.5

The 1st quartile is 2,2,2  is the middle number   = 2

The third quartile is   3,3,6  is the middle number is 3

The interquartile range is 3-2 =1

The mean average deviation is

First find the mean: ( 2+2+2+3+3+6)/6 =18/6 = 3

Then find how far each point is from the mean

(3-2) + (3-2) + (3-2) + (3-3) + (3-3) + (6-3)  = 6

Divide this by the number of data points

6/6 =1

What is the equation of the graph below?
IgorC [24]
ANSWER

f(x) = (x  +  3)^{2}  - 1



EXPLANATION

The vertex of the graph is at


(-3,-1)


The equation of the graph in vertex form is given by the formula,



f(x) =  a{(x - h)}^{2}  + k


The above graph has a minimum point, hence
a >  \: 0

When we put these values into the equation we obtain,

f(x) = a(x -  - 3)^{2}   +  - 1


This implies that,

f(x) = a(x  +  3)^{2} - 1

The point (-2,0) lies on the line.


a( - 2 + 3)^{2}    - 1 = 0

a = 1


f(x) = (x  + 3)^{2}  - 1

The correct answer is D.
