If you raise -4 to the power of 2, you will get -4x-4. So (-4)^2 is the answer.
Answer:
n=13
Step-by-step explanation:
n-29-33=-49
Always work left to write in these types of equation, so subtract -29-33 to get -62:
n-29-33=-49
n-62=-49
Add 62 to both sides:
n-62=-49
+62 <u>+62</u>
n = 13

Answer:
(a) an = -4·2^(n-1)
Step-by-step explanation:
The form for the general term is ...
an = a1·r^(n-1) . . . . . a1 is the first term; r is the common ratio
For a1=-4 and r=-8/-4 = 2, the rule will be ...
an = -4·2^(n-1)
Answer:
1/3 of an hour = 60/3 = 20 minutes.
250 words / 20 minutes = 12.5 words per minute.
This can be rounded to 13 words per minute as an approximation.
