Answer:
C.) Corresponding; B.) m<6 = m<2; and for the last one you probably have to divide so perhaps it might be 30 .
Step-by-step explanation:
Answer:
A: an = 6n - 9
Step-by-step explanation:
third term in an arithmetic sequence is 9
a3 = a + 2d
a + 2d = 9
the fifth term is 21
a5 = a + 4d
a + 4d = 21
a + 2d = 9 (1)
a + 4d = 21 (2)
Subtract (1) from (2) to eliminate a
4d - 2d = 21 - 9
2d = 12
d = 12/2
d = 6
Substitute d = 6 into (1)
a + 2d = 9 (1)
a + 2(6) = 9
a + 12 = 9
a = 9 - 12
a = -3
nth term of this sequence = a + (n - 1)d
= -3 + (n - 1)6
= -3 + 6n - 6
= 6n - 9
an = 6n - 9
Answer:
x = 13
y = 9
Step-by-step explanation:
Answer: 6 fishes
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere = 4/3 x π x (diameter/2)^3
Replacing with the values given:
V = 4/3 x π x (20/2)^3
v = 4/3 x π x (10)^3 = 4,188.79 in3
Finally, we have to divide the volume of the fish tank by the volume that each goldfish needs.
4,188-79 / 693 = 6.04 = 6 fishes
Feel free to ask for more if needed or if you did not understand something.
