Answer:
The function will be: f(n) = 2n
Step-by-step explanation:
An arithmetic sequence is a sequence where the common difference between consecutive terms is same
The sequence according to given information is:
2,4,6...
Here
a_1 = 2
a_2 = 4
a_3 = 6
the common difference will be:
The arithmetic sequence is given by:
Putting the values
Hence,
The function will be: f(n) = 2n
Answer:
the coefficient of the 2nd term: - 38
Step-by-step explanation:
V = 2x (4x + 1) (5x - 6)
=(8x² + 2x) (5x - 6)
= 40x³ - <u>38</u> x² - 12x
Answer:52
Step-by-step explanation:
Given
one-fifth of the plants in a garden are grape tomato plant
two-ninth of the plants in the garden are cherry tomato plants
Also there are 18 grape tomato and 20 cherry tomato plants.
Let Total plants be x
Then Grape tomato plants
x=90
thus there are total of 90 plants
also grape tomato+cherry tomato=18+20=38
Thus there are 90-38=52 remaining plants.
Can't give you the "expression" but here's the rest....
(b) 60+20=80; 150+10=160 answer: Tom (1st month pay) and 60+(20x12)=300;
150+(10x12)=270 answer: Edward.
(c) 60+(20x9)=240; 150+(10x9)=240 answer: 9th month.
(d) the better deal for a gym membership would be the membership to the Superfit Gym. The reason is because by the end of the 12 month year, Edward will pay $270.00 instead of $300.00 that Platinum Gym will charge.
