Answer:
D
Step-by-step explanation:
The answer is A, 2x represents two times the number minus 25% is 0.25 as a decimal answer.
(n-5)+45
<span>where n is the number, you always take away 5 and you add 45 because that is the first number of the sequence</span>
D. V=12 R=12
I=V/R so Current = 1 amp
e.3 ohm resistor
V=IR
V=3 V
At the 4 ohm
4 V
And at the 5 ohm
5 volts
f. The voltage drops across the resistors add up to give the voltage supplied by the battery
4
Answer:
Step-by-step explanation:
<u>Given sequence:</u>
<u>It is an AP with:</u>
- The first term is a = -4
- Common difference is d = 5
<u>Nth term of this sequence is:</u>
- aₙ = a + (n - 1)d
- aₙ = - 4 + 5(n - 1) = -4 + 5n - 5 = 5n - 9
Correct option is d.
