Bruce collects the data on four electric circuits listed in the table. a 3 column table with 4 rows. the first column is labeled
cricket20 [7]

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, R=38\ \Omega

<h3>What is the formula for ohm's low?</h3>

The formula of Ohm's low is V=IR

I=\dfrac{V}{R}

I=\dfrac{18\ V}{38\ \Omega}

I=0.47

q=0.47\times8

So charge,q=It

q=3.76\ C

For x :

Voltage, V=24\ V

resistance, R=34\ \Omega

so, V=IR...(Ohm's low)

I=\dfrac{V}{R}

I=\dfrac{24\ V}{34\ \Omega}

I=0.705

q=0.705\times8

So charge,q=It

q=5.64\ C

For y :

Voltage, V=34\ V

resistance, R=70\ \Omega

so, V=IR.......(Ohm's low)

I=\dfrac{V}{R}

I=\dfrac{34\ V}{70\ \Omega}

I=0.485

q=0.485\times8

So charge,q=It

q=3.88\ C

For z :

Voltage, V=12\ V

resistance, R=18\ \Omega

so, V=IR......(Ohm's low)

I=\dfrac{V}{R}

I=\dfrac{12\ V}{18\ \Omega}

I=0.66

q=0.66\times8

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.

think of 83 as 80 + 3
80/4 = 20
3/4= 3/4
20+3/4 = 20 3/4 thats your mixed number  or 20 and 3/4 twenty and three fourths

If you invest $1,500 today in a bank that gives you a 5 percent annual interest rate, which of these items can you buy in two ye
Andre45 [30]
<span>First, we must calculate the amount that will be available after two years. This is given by: Amount = initial amount * (1 + interest rate)^time Amount = 1500 * (1 + 0.05)^2 Amount = $1,653.75 Therefore, the only items you can buy using this amount are the electronics worth $1,650</span>

The first three steps of completing the square to solve the quadratic equation x^2+8x+5=0
defon
Subtract 5 from both sides
X^2 +8x =-5


2. 8/2=4

3. 4^2=16

Add 16 to both sides

X^2+8x+16=-5+16
