Answer:
-3x^3+74x-5
Step-by-step explanation:
(x+5)(-3x^2+15x-1)
-3x^3+15x^2-x-15x^2+75x-5
-3x^3+15x^2-15x^2+75x-x-5
-3x^3+74x-5
Answer:
<u>-53</u>, f(n) = -6(n-1) + 13
Step-by-step explanation:
given the equation to this linear/arithmetic sequence for the nth term: f(n) = -6(n-1) + 13
f(12) = -6(12-1) + 13
f(12) = -6(11) + 13
f(12) = -66 + 13
f(12) = -53
*substitute and simplify*
______________
f(n) = f(1) + d(n-1)
given f(1) = 13, f(2) = 7, and f(3) = 1
7-13 = 1-7 = <u>-6</u> = d
= f(1) + d(n-1)
f(1) = <u>13</u> so
the equation must be f(n) = <u>13</u> <u>-</u><u> </u><u>6</u>(n-1) or -6(n-1) + 13
Answer:
24.2 feet.
Step-by-step explanation:
pythagorean theorem will solve this so A^2 + B^2=C^2
we have a and c so you do c -a and square root it to get your answer
Answer:
2, 6, 10, 14, 18
Step-by-step explanation:
You start at 2 then add 2+4 which eqaul 6 and keep adding 4
Example:
2+4= 6. 6+4=10. 10+4=14. 14+4=18
N
J corresponds to N as they are both on the same line just on different sides of the graph
