Answer:
Step-by-step explanation:
x^2.x^1
=9^2.9^1
= 9 multiplied by 9
=81
9 multiplied by 1
=9
81 multiplied by nine
=585.198599
Y=12+2x
y represents the number of pieces she now knows, x represents the number of weeks she has taken lessons, 2 is the slope (the number of pieces she'll learn each week), and 12 is the y intercept (the number of pieces she knew before taking lessons).
To solve the equation for 11 weeks, we replace x with 11.
2×11+12= 24
y=24
Answer:
Ok so QR=10 because x=5 and the bisector I believe is LM :)
Step-by-step explanation:
The problems of physics that are given here can be solved using Ohms laws. As per the Ohms law, we can write
Resistance = Current/Voltage.
Now coming to the questions that are given.
1. In this question,
Current = 15 amperes
Voltage = 5 volts
Then
Resistance = 5/15
= 1/3
= 0.33 ohms
So the resistance of the tube will be 0.33 ohms
2. Given information's are noted below
Current = 2 amperes
Voltage = 120 volts
Resistance = 120/2
= 60 ohms
So 60 ohms of resistance is present in the bulb.
3. Given information's
Current = 250 watt
Voltage = 240 volts
Resistance = 250/240
= 25/24
= 1.04 ohms.
The radio will draw 1.04 ohms.
