Answer:

<em>6.73</em> × 10^{-8}

Step-by-step explanation:

7.4 × 10^{-8}

6.7 × 10^{-9} = 0.67 × 10^{-8}

7.4 × 10^{-8} - 0.67 × 10^{-8} = ( 7.4 - 0.67 ) × 10^{-8} = <em>6.73 ×</em> 10^{-8}

Answer:

0.0000000673

Step-by-step explanation:

7.4*10^-8=0.000000074

6.7*10^-9=0.0000000067

0.000000074-0.0000000067

=0.0000000673=673*10^-10

Review of Significant Figures: How many significant figures does the result of the following calculation have: 24.78*(37.3-31.72
horsena [70]

Answer:

The significant figure of the result is 138.8

Step-by-step explanation:

24.78*(37.3 - 31.72)

Solving the bracket first:

37.3 - 31.72 = 5.58

A zero is added to 37.3 before the substraction, so;

37.3 - 31.72 = 37.30 - 31.72 = 5.58

Following the rule of significant figure; we have the answer of the substraction as 5.6 since the least number of significant is one decimal place.

The new expression will be:

24.78 * 5.6 = 138.768

Therefore, the result of our expression 138.8 by following the rule of significant figure

The function f is defined as follows for the domain given.
SCORPION-xisa [38]

Answer:

The range of the function in ascending order is:

Range R = {-2, 0, 2, 4}

Step-by-step explanation:

Given the function

f(x) = 2-2x

We know that the domain of the function is the set of input or arguments for which the function is real and defined.  

In other words,  

  • Domain refers to all the possible sets of input values on the x-axis

As the domain of the function is given such as

Domain D = {-1, 0, 1, 2}

<u>Determining the range </u>

We also know that range is the set of values of the dependent variable for which a function is defined.  

In other words,  

Range refers to all the possible sets of output values on the y-axis.

As the domain is

Domain D = {-1, 0, 1, 2}

FOR x = 1

substitute x = -1 in the function

f(x) = 2-2x

f(-1) = 2-2(-1) = 2+2=4

so

at x = -1, y = 4

FOR x = 0

substitute x = 0 in the function

f(x) = 2-2x

f(-1) = 2-2(0) = 2-0=2

so

at x = 0, y = 2

FOR x = 1

substitute x = 1 in the function

f(x) = 2-2x

f(-1) = 2-2(1) = 2-2=0

so

at x = 1, y = 0

FOR x = 2

substitute x = 2 in the function

f(x) = 2-2x

f(-1) = 2-2(2) = 2-4=-2

so

at x = 2, y = -2

Thus combining all the output or y values correspond to the given input values, we get the range of the function.

Thus, the range of the function in ascending order is:

Range R = {-2, 0, 2, 4}
