Answer:
Basically, when a scientific calculator displays a number as aEb, it means to move the decimal point in a as follows:
If b is positive, move the decimal point b units to the right.
If b is negative, move the decimal point b units to the left.
Step-by-step explanation:
It’s the first one, seven (7)
Answer:
-7x⁸ + 5x⁷ - 11x + 2
Explanation:
Before we begin, remember the following:
(-ve) * (-ve) = +ve
(-ve) * (+ve) = -ve
(+ve) * (+ve) = +ve
(+ve) * (-ve) = -ve
Now, for the given we have:
(5x⁷ - 8x + 2) - (7x⁸ + 3x)
First, we will get rid of the brackets based on the above rules. This will give us:
5x⁷ - 8x + 2 - 7x⁸ - 3x
Next, we will combine like terms as follows:
5x⁷ + (-8-3) x - 7x⁸ + 2
This will give us the final expression:
-7x⁸ + 5x⁷ - 11x + 2
Hope this helps :)
Answer:
A) A graphic rating scale- a scale where the participant places his or her response along a line or continuum; the score or measurement is its distance in millimeters from either endpoint.
B) A multiple rating list- a single interval or ordinal numerical scale where raters respond to a series of objects; results facilitate visualization.I will recommend a multiple rating list, because it is an easier process to conduct in a employee environment.
Step-by-step explanation:
The circumference of a circle is pi x 2 x radius.
To find the radius, divide the circumference by pi, then divide that by 2:
36/3.142 = 11.4576703
Radius = 11.4576703/2 = 5.7288
Rounded to one decimal place the radius is 5.7 units.
