1) The domain is represented in interval notation as [0, 20]. 2) The range is denoted as [100, 700]. Given that Beth saves $30 per month for 20 months and started with an account of $100, we express the total amount saved as Y = $100 + $30 × X, allowing us to accurately define both the domain and range.
The dimensions of the book cover are 28.3 centimeters in length and 21 centimeters in width. Calculate the range of values for both the actual length and width of the book cover. Minimum length = (28.3 - 0.05) cm and maximum length = (28.3 + 0.05) cm, thus 28.25 cm ≤ length < 28.35 cm.
Hope this information is helpful!
m = 6.57 and n = -2
Detailed explanation:
To solve this question, convert the thickness of a dollar bill into standard notation and compare the two thicknesses.
0.07 compared to 0.0043 results in 0.0657
0.0657 = 6.57 x 10^-2
Thus, a quarter is thicker than a dollar by 6.57 x 10^-2.
m = 6.57 and n = -2
