For the answer to the question above,
a1 = 40
<span>a2 = 20 </span>
<span>a3 = 10 </span>
<span>.. </span>
<span>aN = (1/2^N-1) a1 { in general aN= (r^N-1) A1 </span>
<span>a5 = (1/2^4) 40 = 40/16 = 2.5
</span>
So the answer to your question is 2.5
I hope my answer helped you. Feel free to ask more questions. Have a nice day!
<u>Answer:</u>
-
It will take 1 week for both classmates to catch up with each other
- Each child has passed about 9 tests.
<u>Step-by-step explanation:</u>
<u>We know that:</u>
-
Q = 8 + 1(w)
- S = 4 + 5(w)
- Q = S
<u>Work:</u>
-
8 + w = 4 + 5w
- => 8 - 4 = -w + 5w
- => 4 = 4w
- => w = 1
<u>Hence, it will take 1 week for both classmates to catch up with each other. Now, let's substitute the value of w into the first equation to find how many tests have each child passed.</u>
-
Q = 8 + (w)
- => Q = 8 + 1
- => Q = 9
Hence, <u>each child has passed about 9 tests.</u>
Hoped this helped.
Answer:
A and C
Step-by-step explanation:
A) y = (1/2)x + 2 {Compare with y =mx +b}
slope = (1/2)
C) y = -2x + 4
Slope = -2
When product of two slopes is (-1), then the lines are perpendicular.
