Henry divides 1.060 g by 1.0 mL to find the density of his water sample. How many significant figures should he include in the density value that he reports?

Answers

2 Significant figures should be include in the density value that Henry reports.

What is Significant figure?

" Significant figure are those digit of number which are important in terms of accuracy. They are single digit number from 0 to 9, which express the message of accuracy."

According to question,

Henry divides 1.060g by 1.0mL

1.060 has 4 significant figure

1.0 has 2 significant figure

As per division rule of significant figure

When we divide two more numbers, count the significant figure of the given number. Least is the significant figure of the concluded one.

Here 2 is the lowest among two.

Hence, we conclude that 2 Significant figures should be include in the density value that Henry reports.

If you buy 10 printers for your office and each printer costs $199, what is your cost for all 10?a. $2,990
b. $1,999
c. $1,990

Two factors of –48 have a difference of 19. The factor with a greater absolute value is positive.. . Give the sum of the factors given?. . –19.
–13.
13.
16

Answers

x y = - 48
x - y = 19
y = x - 19
x ( x - 19 ) = - 48
x² - 19 x + 48 = 0
x² - 3 x - 16 x + 48 = 0
x ( x - 3 ) - 16 ( x - 3 ) = 0
( x - 3 ) ( x - 16 ) = 0
Factors : x = 16, and y = -3
( 16 * ( -3 ) = -48; 16 - (-3 ) = 16 + 3 = 19 )
Sum of the factors : 16 + ( -3 ) = 16 - 3 = 13
Answer : C ) 13.

4. If a function, f(x) is shifted to the left four units, what function represents the transformation?. A. f(x-4). B. f(x) - 4. C. f(x+4). D. f(x) + 4. .

Answers

If a function, f(x) is shifted to the left four units, thefunction that represents the transformation would be f(x+4). Thecorrect answer between all the choices given is the third choice or letter C. Iam hoping that this answer has satisfied your query about and it will be ableto help you.

f(x) shifted left 4 units is represented by f(x - (-4)) = f(x + 4). [-4 because ot was shifted LEFT]
