A of n = 2n^2 - 3
the nth term = 2 times n to the power of 2 minus 3
Answer:
this is quite easy. if the tire is 14 ft. tall, that would mean the diameter is 14 ft. as well (do to a tire being round). the radius is half of the diameter, meaning the radius is 7 ft. finally, to find the circumference, you would have to multiply pi by 2 (6.28) then multiply this by the radius to make 43.98 ft.
Step-by-step explanation:
D = 14
R = 14/2 = 7
C = 2(pi) x 7 = 6.28 x 7 = 43.98
Answer:
Given Two equations :-
- multiplying eq.(i) by 2 eq.(ii) by 3.
- <u>placing this value of y² in eq. (i)</u>
3x²- 2×9 = 57
3x² - 18 = 57
3x² = 57 + 18
3x²= 75
x² = 25
<u>x = ± 5</u>
<h3>So, the values of x are <u>+5 and -5</u> </h3><h3>and the values of y are
<u>+3 and -3</u></h3>
