Answer:
41.99 or 42.0 volts.
Step-by-step explanation:
We have been given the impedance (Z) of the circuit which is:
[tex]Z=3.342+4.176i[/tex]
and the current through the circuit is:
[tex](5.772-5.323i)[/tex]
The voltage across the circuit is given by:
[tex]V= I\times Z=IZ[/tex], where 'V' is the voltage, 'I' is the current, and 'Z' is the impedance.
Plugging the values of 'I' and 'Z' we get:
[tex]V=(5.772-5.323i)\times 10^{-3}\times (3.342+4.176i)\times 10^3[/tex]
[tex]V=(5.772-5.323i)\times(3.342+4.176i)[/tex]
[tex]V= (41.51+6.31i)[/tex]
Now that we have the voltage, we can find the magnitude of the voltage as follows:
[tex]V= \sqrt{(41.51)^2+(6.31)^2}=\sqrt{1723.08+39.81}=\sqrt{1762.89}=41.98 \approx 42.0[/tex]
So the magnitude of the voltage across the circuit is 42.0 Volts.
find the least common multiple of 4 and 7
28 is the least common multiple. To find the least common multiple, you look through the numbers both 4 and 7 go into. The smallest of those number is the least common multiple, or LCD.
Answer: The least common multiple of 4 and 7 is 28.
Step-by-step explanation:
↓↓↓↓↓↓↓↓
First, find the prime factorization of 4.
2×2=4
Next, find the prime factorization of 7.
7×1=7
Then, multiply each factor the greater number of times it occurs.
7×2×2=28

what is the y intercept of -3x-5y=60
Answer: y-intercept = -12
Step-by-step explanation:
[tex]-3x = 60+5y[/tex] Add [tex]5y[/tex] on both side
[tex]-3x-60 = 5y[/tex] Subtract [tex]60[/tex] on both sides
[tex]-\frac{3}{5}x-12=y[/tex] Divide 5 on both sides
The y-intercept of the line -3x - 5y = 60 is equal to -12.
What is the slope-intercept form?In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;
y = mx + b
Where:
m is the slope or rate of change.x and y are the points.b is the y-intercept or initial value.Based on the information provided about this line, a linear equation in standard form that models it is given by;
-3x - 5y = 60
By making y the subject of formula, we have the following:
5y = -3x - 60
y = -3x/5 - 12
By comparison, we have the following:
y-intercept, b = -12.
slope, m = -3/5.

shen baked b cookies. his family ate 11 of them. using b, write an expression for the number of cookies that remained.
Step-by-step explanation:
So, lets write out the equation you have right now.
B - 11 = ?
You can have B be whatever you want. It must be higher than 11 (unless your teacher or whoever your guardian is allows negative numbers). In this case, I will use 15.
B = 15
15 - 11 = ?

What is the Recipical of 8/19?
The question states that we are looking for the reciprocal of 8/19.
Recall what a reciprocal is. A reciprocal, when looking at a number, is what is multiplied with it for it to equal 0. It is commonly regarded as just the fraction flipped. (For example, the reciprocal of 1/2 would be 2, or 2/1. 2 * 1/2 = 1)
But why does flipping a fraction work?This goes back to the simplifying, when multiplying two fractions together.
If you were to multiply two fractions, say [tex]\frac{5}{4}[/tex] and [tex] \frac{4}{5}[/tex], you could look at the numerator of one and the denominator of another, and cancel them out. In this case, the numerator of one is 5, and the other is also 5. Cancelling those out makes both one. If you cancel out 4 and 4 too, you get 1/1 * 1/1, or just 1.
We could go on asking why these methods work forever. Why does cancelling out a numerator and a denominator of separate fractions work? (A simple explanation is when the separate fractions are multiplied together, you could divide both sides by the factor which was originally used to cancel out with, which is what was stated above but simpler.)
Now, we can figure out the answer.Since we know the reciprocal is just the flipped form of the fraction, we can simply flip 8/19 to get our answer.
8/19 flipped is 19/8, which is our answer.
Hope this helped!1 1/3x2/3= what is the answer ? How do I do this?
1 1/3 is simplified to 4/3
multiply 4/3 * 2/3 =8/9
1 1/3 x 2/3 = 4/3 x 2/3 = 8/9 = 1 1/9
When you are multiplying fractions, you would multiply them like you would regular numbers. first, multiply the the numeraters together, then the denominaters together.
Example: 3/8 x 5/7 = 15/56
When you are multiplying whole fractions, you need to make them improper first before you multipy. Then you can multipy like normal.
Example: 2 3/4 x 6 2/4 = 11/4 x 26/4 = 286/16 (which can be simplified to 71 1/2

We want to find the value of x
Simplifying we have to:
[tex]\frac{1}{8} = 0.125\\\\\frac{1}{2} = 0.5\\[/tex]
Therefore:

Fifteen percent of an employee’s taxable income is collected each paycheck. Before taxes are removed from each paycheck, $350 of tax-exempt expenses is taken out. If the variable x represents the employee’s pay before tax-exempt expenses and taxes are removed, which expression represents the employee’s take-home pay after these deductions?
Answer:
0.85(x - 350)
Step-by-step explanation:
Here "x" represents the pay before tax.
Take exempted amount = 350.
The taxable amount = x - 350.
The tax rate = 15% = 15/100 = 0.15
Take home pay after the tax deduction = Taxable amount - tax
= (x - 350) - 0.15(x - 350)
Now we have to simplify this.
= (x - 350)(1 - 0.15)
= (x - 350)(0.85)
The employee’s take-home pay after these deductions= $0.85(x - 350).
Thank you.

Drag the correct steps into order to solve the equation -3x – 6 = 18 for x.
The solution to the linear equation -3x - 6 = 18 is x = - 8
What is the solution of the equation?The solution of the linear equation is calculated as follows;
The given linear equation;
-3x - 6 = 18
Move the constant term to the other side of the equation.
-3x - 6 + 6 = 18 + 6
-3x = 24
Divide both sides of the equation by the coefficient of x (-3) to isolate x.
(-3x) / (-3) = 24 / (-3)
x = -8
Thus, the solution to the linear equation -3x - 6 = 18 is x = - 8

a swimming center builds a new pool that has the dimensions 3a^6 by a^2 by b4 . what is the volume of the pool
Answer:
Volume = length * width * depth
= 3a^6 * a^2 * b^4
= 3a^(6+2)b^4
= 3a^8b^4 cubic units Answer.
Step-by-step explanation:
The exponents 6 and 2 are added when the terms are multiplied
Swimming pool is generally build as a cuboid.
Volume of cuboid refers to the measurement of the space in the cuboid. It is the product of length, breadth and height of the cuboid.
Therefore the formula to calculate volume of cuboid will be:
[tex]\rm Volume\:of\:cuboid = \rm length\times breadth \times height[/tex]
The volume of the pool will be [tex]\rm 3a^8 b^4[/tex].
To reach the above answer, following calculations are required:
Given:
Dimensions of the pool:
[tex]\begin{aligned} \rm Length &= 3a^6\\\rm Breadth &= a^2\\\rm Height &= b^4\end[/tex]
Therefore, volume of pool will be as follows:
[tex]\begin{aligned} \rm Volume\:of\:cuboid &= \rm length\times breadth \times height\\&= 3a^6 \times a^2 \times b^4 \\&= 3a^{6+2}b^4\\&= 3a^8b^4 \end[/tex]
Volume of pool = [tex]\rm 3a^8b^4[/tex]

(7x²+10y²-2x) is what I got.
(7x-10y-2x) is what Marcus got.
Marcus didn't add the squared symbol for 10y and he added a negative sign for 10y. He did -10y but it is +10y² because -2y²+12y²=10y². So, his problem is that Marcus didn't add right.

Martina counts the number of candy pieces in each bag and plots the results on two dot plots. A dot plot is shown. The title of the plot is Brand A. The line is numbered with tick marks at 40, 45, 50, 55, 60, 65, and 70 and is labeled Number of Candy Pieces. There are 2 dots at 52, 1 dot at 53, 2 dots at 55, 1 dot at 56, 2 dots at 57, and 2 dots at 62. A dot plot is shown. The title of the plot is Brand B.

The number of candies in the bags from Brand B is greater and less consistent than the number of candies in the bags from Brand A is valid statement.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Lets compare the dot plots of the two brands.
In Brand A,
The number of candy pieces per bag ranges from 52 to 62, and the dots are relatively evenly spread out across this range.
In Brand B,
the number of candy pieces per bag ranges from 44 to 69, and the dots are more spread out, with a larger range of values.
As we observe the majority of the dots are clustered around 52, 55, 62, 65, and 67, indicating that these values are more common in Brand B than in Brand A.
Brand B has more dots in total than Brand A, suggesting that Brand B generally has more candy pieces per bag than Brand A..
Hence, the number of candies in the bags from Brand B is greater and less consistent than the number of candies in the bags from Brand A is valid statement.
