<h3>
Answer: d. 0, 6, 18, 36</h3>
================================================
Work Shown:
Plug in n = 1 to find the first term
d_n = 3n(n-1)
d_1 = 3*1(1-1)
d_1 = 0
The first term is 0
Then repeat for n = 2
d_n = 3n(n-1)
d_2 = 3*2(2-1)
d_2 = 6
The second term is 6
We have enough to stop here since the sequence {0, 6, ...} is shown by choice D, while the other answer choices have a different two starting values.
------
If you were to keep going, then it would look like this
Plug in n = 3
d_n = 3n(n-1)
d_3 = 3*3(3-1)
d_3 = 18
The third term is 18
and plug in n = 4
d_n = 3n(n-1)
d_4 = 3*4(4-1)
d_4 = 36
The fourth term is 36.
Answer:
52500
Step-by-step explanation:
5% of 50000 is 2500
(50000 * 0.05 = 2500)
50000 + 2500 = 52500
another way to do it is just multiply 50000 by 1.05 (105%)
Answer:
Step-by-step explanation:
Hello there, to answer this question, one must know the formula of area of a circle.
1. Use formula for area of circle to find area of base of cylinder
2. Multiple area of base with height of cylinder for volumne
Area = pi * r * r
Cylinder A:
Area: pi * 6 * 6 = 113.1 inches square
Volumne = Area * Height = 113.1 * 4 = 452.4 inches cube
Cylinder B:
Area: pi * 5 * 5 = 78.54 inches square
Volumne = Area * Height = 78.54 * 5 = 392.7 inches cube
Cylinder C:
Area: pi * 4 * 4 = 50.27 inches square
Volumne = Area * Height = 50.27 * 6 = 301.62 inches cube
Answer:
23.3 mpg
Step-by-step explanation:
For the unit rate of miles per gallon (mpg)
140 miles / 6 gallons = 23 1/3 mpg = 23.3 mpg
The sum of 6x - 2 and 2x - 7 is 8x - 9
<em><u>Solution:</u></em>
Given that we have to find the sum of 6x - 2 and 2x - 7
"Sum" means we have to add both the expressions
Sum of 6x - 2 and 2x - 7:
Remove the parenthesis and solve
Combine the like terms
The like terms are terms that have the same variables and powers. The coefficients do not need to match
Here like terms are 6x and 2x
Thus the sum is 8x - 9
