The Bruce must include X and Z in his report.
We have given the data on four electric circuits listed in the table
For w :
Voltage, V=18\ V
resistance, [tex]R=38\ \Omega[/tex]
What is the formula for ohm's low?The formula of Ohm's low is V=IR
[tex]I=\dfrac{V}{R}[/tex]
[tex]I=\dfrac{18\ V}{38\ \Omega}[/tex]
I=0.47
[tex]q=0.47\times8[/tex]
So charge,q=It
q=3.76\ C
For x :
Voltage, V=24\ V
[tex]resistance, R=34\ \Omega[/tex]
so, V=IR...(Ohm's low)
[tex]I=\dfrac{V}{R}[/tex]
[tex]I=\dfrac{24\ V}{34\ \Omega}[/tex]
I=0.705
[tex]q=0.705\times8[/tex]
So charge,q=It
q=5.64\ C
For y :
Voltage, V=34\ V
resistance, [tex]R=70\ \Omega[/tex]
so, V=IR.......(Ohm's low)
[tex]I=\dfrac{V}{R}[/tex]
[tex]I=\dfrac{34\ V}{70\ \Omega}[/tex]
I=0.485
[tex]q=0.485\times8[/tex]
So charge,q=It
q=3.88\ C
For z :
Voltage, V=12\ V
resistance, [tex]R=18\ \Omega[/tex]
so, V=IR......(Ohm's low)
[tex]I=\dfrac{V}{R}[/tex]
[tex]I=\dfrac{12\ V}{18\ \Omega}[/tex]
I=0.66
[tex]q=0.66\times8[/tex]
So charge,q=It
q=5.28\ C
Therefore, the circuits X and Z deliver 5.64 C and 5.28 C of charge.
Hence, Bruce must include X and Z in his report.

3x2-9=0 GCF. It’s Precalculus btw
Answer:
x = ± [tex]\sqrt{3}[/tex]
Step-by-step explanation:
3x² - 9 = 0 ( add 9 to both sides )
3x² = 9 ( divide both sides by 3 )
x² = 3 ( take square root of both sides )
x = ± [tex]\sqrt{3}[/tex]
or
3x² - 9 = 0 ← factor out 3 from each term
3(x² - 3) = 0
equate x² - 3 to zero and solve for x
x² - 3 = 0 ( add 3 to both sides )
x² = 3 ( take square root of both sides )
x = ± [tex]\sqrt{3}[/tex]

A rectangular driveway is 7 feet wide, and it has an area of a square feet. How long is the driveway?
Please give how to solve every step
☆ Thank you ☆
Answer:
x = a/7
Step-by-step explanation:
Area is length x width, so let's call our unknown, the length, x
So the total area is 7 (the width) times x
If the total area is a, then we can write the equation a = 7(x)
Next, we have to isolate the variable for the length, x
To do this, we divide both sides by 7, leaving a/7 = x, or x = a/7

The answer will be t=-35Sin{[tex]\pi[/tex]/6m)+55 average daily temperature, t, in degrees Fahrenheit for a city as a function of the month of the year.
What is temperature?Temperature is the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
For the equation: 35cos(pi/6(m+3)+55)
Simplify it by multiplying pi/6 in the bracket values:
[tex]=35 Cos (\dfrac{\pi m}{6}+\dfrac{3\pi }{6}+55)[/tex]
[tex]=35 Cos(\dfrac{\pi m}{6}+55+\dfrac{\pi}{2})[/tex]
Now suppose x = m.pi/6+55, while pi/2 = 90⁰

B) A 3-year loan with a 4. 00% interest rate compounded annually. C) A 4-year loan with a 3. 75% interest rate compounded annually. D) A 5-year loan with a 3. 00% interest rate compounded annually
The loan option that would allow Charles to pay the LEAST in interest is option A.
What is Compound Interest?Compound Interest is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. and this continues for t period of time.
It is given by the formula,
[tex]A=P(1+r\%)^n[/tex]
where A is the value after t period of time, P is the principal amount, and,
r is the rate of interest.
A.) Principle amount = $10,000
Time Period of loan = 2 years
Rate of Interest = 4.75% per annum
Now, the total amount can be written as
[tex]=P(1+r\%)^n\\\\= \$10,000 \times (1+0.0475)^2\\\\= \$10,972.56[/tex]
The interest will be = $10,972.56 - $10,000 = $972.56
B.) Principle amount = $10,000
Time Period of loan = 3 years
Rate of Interest = 4.00% per annum
Now, the total amount can be written as
[tex]=P(1+r\%)^n\\\\= \$10,000 \times (1+0.04)^2\\\\= \$11,248.64[/tex]
The interest will be = $11,248.64 - $10,000 = $1,248.64
C.) Principle amount = $10,000
Time Period of loan = 4 years
Rate of Interest = 3.75% per annum
Now, the total amount can be written as
[tex]=P(1+r\%)^n\\\\= \$10,000 \times (1+0.0375)^2\\\\= \$11,586.5[/tex]
The interest will be = $11,586.5- $10,000 = $1,586.5
D.) Principle amount = $10,000
Time Period of loan = 5 years
Rate of Interest = 3.00% per annum
Now, the total amount can be written as
[tex]=P(1+r\%)^n\\\\= \$10,000 \times (1+0.03)^5\\\\= \$11,592.74[/tex]
The interest will be = $11,592.74 - $10,000 = $1,592.74
Hence, the loan option that would allow Charles to pay the LEAST in interest is option A.
