The formula I = √W/R gives the electric current I in amperes that flows through an appliance, where W is the power in watts and R is the resistance in ohms. Which set of numbers best describes the value of I for the given values of W and R ? W=100, R=25

Answers

Answer 1

The equation be I = √W/R  

Where I is the current.

W stands for electrical power.

R stands for resistance in ohms then the value of I = 1.414

What is meant by electrical power?

A circuit's ability to transport electrical energy is referred to as its electric power. One joule per second, or one watt, is the SI unit of power. Similar to other SI units, watts have standard suffixes that refer to thousands, millions, and billions of watts as kilowatts, megawatts, and gigawatts, respectively.

Let the equation be I = √W/R

Where W and R are both within the square root symbol and 

I is the current.

W stands for electrical power.

R stands for resistance in ohms.

When W = 100, R = 25, to solve for the value of I for each set.

I = √100/25

The square root of I = √4

W = 100, R = 50 and I = 2.

I = √100/25

The square root of I = √2

Therefore, the value of I = 1.414

Which line is parallel to the line 5 x+6 y=30 ?
f. 5 x+9 y=30
g. 9 x+6 y=30
h. 5 x+6 y=9
i. 6 x+5 y=30

Answers

The equation of the line h. 5x + 6y = 9 is parallel with the equation of the line 5x + 6y = 30.

Two lines are parallel with each other if they do not intersect no matter how much you extend both lines. Parallel lines have equal slopes.

The slope, m, determines the steepness of a line. It can be measured by the vertical distance from one point to another divided by the horizontal distance of the same points. In an equation in slope-intercept form, y = mx + b, the slope, m is the coefficient of x.

Determine the slope of the given line and each given choices by transforming each into slope-intercept form.

5x + 6y = 30

6y = -5x + 30

y = -5/6 x + 30/6

y = -5/6 x + 5

m = -5/6

f. 5x + 9y = 30

9y = -5x + 30

y = -5/9 x + 30/9

y = -5/9 x + 10/3

m = -5/9

g. 9x + 6y = 30

6y = -9x + 30

y = -9/6 x + 30/6

y = -3/2 x + 5

m = -3/2

h. 5x + 6y = 9

6y = -5x + 9

y = -5/6 x + 9/6

y = -5/6 x + 3/2

m = -5/6

i. 6x + 5y = 30

5y = -6x + 30

y = -6/5 x + 30/5

y = -6/5 x + 6

m = -6/5

Since h. 5x + 6y = 9 has a slope of -5/6 and equal to the slope of the given line, then they are parallel lines.

Explain how point-slope form is related to the formula for slope.

Answers

The point slope form finds the equation of a straight line that passes through a given point and is inclined to the x-axis. Each point on a line must satisfy the line's equation. Two-variable linear equations symbolize lines. The point slope formula is utilized when we know the line's slope and a point. The next section explains the point slope form and how to calculate its formula.

The equation of a straight line that is inclined at a particular angle to the x-axis and passes at a given point may be found by using the point slope form. This form is used to get the equation of the line. An equation may be said to be the equation of a line if it can be shown to be fulfilled by every point along the line. This indicates that a line is represented by a linear equation that has two variables. Whereas the Point slope formula is only used in situations in which both the slope of the line and a point on the line are known. In the next part, let's get more in-depth knowledge about the point slope form as well as how to derive the formula that is used to express the point slope form.

Answers

Answer:  3.4 x 10^1  mg

=====================================================

Explanation:

Multiply the given values. This is because,

total mass = (number of paperclips)*(mass per paperclip)

So,

(5.0 x 10^−4)(6.85 x 10^4)

(5.0 * 6.85) x (10^−4 * 10^4)

34.25 x 10^(-4+4)

34.25 x 10^0

(3.425 x 10^1) x 10^0

3.425 x 10^(1+0)

3.425 x 10^1

3.4 x 10^1

We round the first value to 2 sig figs because it is the smaller sig fig count of 5.0 and 6.85; the 0 in 5.0 is significant.

Notice how I rewrote 34.25 into 3.425 x 10^1. I did this to get the number in the form a x 10^b, where [tex]0 \le a < 10[/tex], which fits scientific notation form.

The value 3.4 x 10^1 simplifies to 34. So an estimate of the total mass is about 34 mg. But we'll stick with scientific notation since your teacher instructed it.

Step-by-step explanation:

For the graphs just look for the middle point, and thats essentially your center, and the radius is how many units the edge of the circle is to the center. So for 1 the center would be (3,4) and the radius 3. For problem 3 use the equation  ( x − a )^2 + ( y − b )^2 = r^2, where you substitute the radius for r, your x center coordinate as a, and your y coordinate as b. In problem 5, use 12 as your x value for the center coordinate, and 5 as your y value. Then just take the root of 16 to get your radius, and apply that to the other problem. Hope this helps :)

Step-by-step explanation:

Part (a)

Theorem:  Interior angles of a quadrilateral sum to 360°.

Given angles:

100°65°100°

Let x be the unknown angle.

⇒ 100° + 65° + 100° + x = 360°

⇒ 265° + x = 360°

We comprehend that the pie's total value is always 100%. It is also assumed that a circle has a circumference of 360°. As a result, the sum of all pieces of data equals 360°. Based on these, there appear to be primarily two pie chart formulas:

We use the mentioned format to calculate a percentage of a set of data: 100 (Frequency ÷ Total Frequency) × 100We use the following equations to convert the data to degrees:  (Informed Data ÷ Total value of Data) × 360°

Now, the stated data of the pie chart are-

When a circle is wholly rotated, the center forms a 360-degree angle.

A complete rotation at the central point of the circle yields 360 degrees.

The total color percentage is 100%.

Divide a red value by 3.6 because 360 ° / 100% = 3.6.

The spinner's pointer displays an overall percentage of red of 40%.

P = 40/3.6 (probability of each pointer landing on red).

Step-by-step explanation:

the sum to n terms of an arithmetic sequence is

where a₁ is the first term and d the common difference

given S₁₄ = - 63 , then

[tex]\frac{14}{2}[/tex] [ 2a₁ + 13d ] = - 63

7(2a₁ + 13d) = - 63 ( divide both sides by 7 )

2a₁ + 13d = - 9 → (1)

the nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

given a₁₄ = - 24 , then

a₁ + 13d = - 24 → (2)

Answers

The line's equation is y=3x-4.

What is Equation of line?

Whenever the equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation where the slope of line is m and b is the y- intercept. The slope is defined as

m = (y-y1)/(x-x1)

Given:

For two lines to be perpendicular to each other, they must have slopes that are negative reciprocals of each other (i.e. the negative reciprocal of n is -1/n). The slope of the given line is –1/3 which means the slope of a line perpendicular to it would be 3.

From the given slope equation of the line

y=3x+b,

where b is the y-intercept. Since we know the line passes through the point (2,2).

(y-2)/(x-2) = 3

y-2 = 3*(x-2)

y=3x-6+2

y=3x-4

The value of b = -4

Jenny's Bakery sells carrot muffins at 2 each. The electricity to run the oven is 120 per day and the cost of making one carrot muffin is 1.40 . How many muffins need to be sold each day to break even?

Answers

If Jenny's Bakery sells carrot muffins at 2 each and the electricity to run the oven is 120 per day and the cost of making one carrot muffin is 1.40, then the number of muffins needed to be sold each day to break even is equal to 200.

The number of muffins needed to be sold each to break even can be determined by forming a linear equation.

A linear equation, sometimes also referred to as a first-degree equation can be described as an equation that contains variables that have the maximum power of not more than one.

The linear equation for this problem will be,

Cost of electricity to run the oven + Cost of making x number of muffins = Sale price of x number of muffins

120 + 1.40 (x) = 2 (x)

Here x is equal to the number of muffins

Rearranging the equation,

120 = 2(x) - 1.40 (x)

120 = 0.6 (x)

120/0.6 = x

x = 200

Hence, 200 muffins are needed to be sold each day to break even.
