To find the seventh term of the geometric sequence, divide first the fifth term by the fourth term to obtain the common ratio. -40 divide by -8 is 5. Then, multiply a5 by the common ratio, 5 twice or a4 by 5 three times. Both solutions will give, an a7 equal to -1000. Thus, a7 is -1000.
Answer:
just divide 18 by 1920 duh
Step-by-step explanation:
Put the given information into the formula and solve for the variable of interest.
.. V = π*r^2*h
.. 252π = π*r^2*7
.. (252π)/(7π) = r^2
.. 36 = r^2
.. 6 = r
The radius is 6 cm. Selection D is appropriate.
_____
We would prefer that the offered selections had the appropriate cm units attached.
