Answer:
a8 = 512.
Step-by-step explanation:
This is geometric sequence with common ratio r = 2 and first term a1 = 4.
nth term = a1 r^(n-1)
So a8 = 4 2(^8-1)
= 4 * 2^7
= 4*128 = 512.
Answer:
13 weeks
Step-by-step explanation:
multiply $30 by 13 weeks you get $390 add the $210 and get $600
Answer:
y = 1500 - 63x. See the attached for a graph.
Step-by-step explanation:
Each withdrawal will total $63, which includes $60 cash and a $3 fee. Then x withdrawals will total 63x dollars. This amount is subtracted from the initial account balance of 1500 to give the amount remaining.
If y represents the account balance, the equation can be written as
... y = 1500 -63x
The graph will have a y-intercept of 1500, and a slope of -63.
Answer:
Using Math.
Step-by-step explanation:
You solve it using math.
See, you should have been more specific with your question, maybe said "What is the answer" not "How do I solve".
But I guess I'll help you out bro
<em>Multiply</em> both sides by 6
that gives you -x>18
then <em>multiply</em> both sides by -1
which means you gotta <u>flip the sign</u>
so final answer is x<-18
Step-by-step explanation:
1. Use the Pythagorean theorem to solve for side KM:
- 16^2+KM^2=34^2
- 256+KM^2=1156
- KM^2=900
- KM=30
2. Cosine is adjacent over hypotenuse, so cosine of M would be KM/34, or 30/34
3. Tangent is opposite over adjacent, so tangent of L will be KM/16, or 30/16
4. Sine is opposite over hypotenuse, so sine of M will be 16/34
5. KM=30, solved for in step 1.
hope this helps!!
